Change log for June 24, 2017 Vulkan 1.0.53 spec update: * Bump API patch number and header version number to 53 for this update. Github Issues: Internal Issues: * Clarify mappings of coordinates for mutable, compatible image views in slink:VkImageViewCreateInfo (internal issue 815). * Make ename:VK_BIND_SFR_BIT require a logical device with multiple physical devices, so that standard sparse image block dimensions are only required on systems that support multi-GPU (internal issue 835). * Convert all files from use of // refBegin .. // refEnd comments to delimit ref pages, to use of open blocks, and update style guide accordingly (internal issue 839). * Add valid usage for slink:VkWriteDescriptorSet when performing updates to a ename:VK_STORAGE_IMAGE descriptor with layout ename:VK_IMAGE_LAYOUT_GENERAL. * Add a hack to the validity generator script to support an odd interaction between flink:vkCmdFillBuffer and an extension (internal issue 853). * Remove redundant text describing slink:VkBufferCreateInfo::pname:usage, which was already covered by implicit valid usage (internal issue 854). * Update implicit validity generator script to properly handle the pname:sType and pname:pNext members of "returnedonly" structures (internal issue 874). * Note that slink:VkApplicationInfo::pname:pApplicationName & slink:VkApplicationInfo::pname:pEngineName are optional, and add missing implicit valid usage statements for flink:vkDestroyInstance. * Added missing valid usage for flink:vkCmdWriteTimestamp to require a timestamp query pool. * Simplify and/or split "`non-atomic`" valid usage statements. New Extensions: * `VK_AMD_gpu_shader_int16` * `VK_EXT_blend_operation_advanced` * `VK_EXT_sampler_filter_minmax` * `VK_NV_framebuffer_mixed_samples` ----------------------------------------------------- Note: the 1.0.52 spec wasn't published on github, so the 1.0.53 release combines both change sets. ----------------------------------------------------- Change log for June 13, 2017 Vulkan 1.0.52 spec update: * Bump API patch number and header version number to 52 for this update. Github Issues: Internal Issues: * Clarify behavior when non-coherent memory has <<memory-device-unmap-does-not-flush, not been flushed before being unmapped>> (internal issue 819). * Fix description of code:WorkgroupSize builtin to note it decorates an object, not a variable (internal issue 836). * Fix asciidoc attributes so that trailing '{plus}' symbols in [eq] style equations are rendered properly (internal issue 845). * Add language to the "`Extension Handles, Objects, Enums, and Typedefs`" section of the Procedures and Conventions document stating that any new handle type requires a corresponding entry in the elink:VkObjectType enumerated type (internal issue 856). * Update style guide to use slink macro for Vulkan handle type names, and define narrow conditions under which to use the *name and *text macros instead of *link (internal issue 886). * Add a dependency of the <<VK_KHX_device_group,VK_KHX_device_group>> extension on VK_KHX_device_group_creation to +vk.xml+ and the extension appendix. * Change the copyright on Vulkan specification asciidoc *source* files to CC-BY 4.0, and update the proprietary Khronos copyright applied to the generated *output* formats (internal issue 327).

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for November 25, 2016 Vulkan 1.0.35 spec update: * Bump API patch number and header version number to 35 for this update. Github Issues: * Document in the <<memory-device-hostaccess,Host Access>> section that mapping and unmapping does not invalidate or flush the mapped memory (public issues 27, 126). * Redefine the entire <<synchronization>> chapter in terms of consistent and well defined terminology, that's called out at the start of the chapter. This terminology is applied equally to all synchronization types, including subpass dependencies, submissions, and much of the implicit ordering stuff dotted around the spec. Key terms are laid out in the <<synchronization-dependencies,Execution and Memory Dependencies>> section at the top of the rewritten chapter (public issues 128, 131, 132, 217, 299, 300, 302, 306, 322, 346, 347, 371, 407). * Specify order of submission for batches in the <<vkQueueSubmit,vkQueueSubmit>> and <<vkQueueBindSparse,vkQueueBindSparse>> commands (public issue 371). * Add valid usage statements to each of the WSI extension sections indicating that the WSI-specific structure parameters must be valid, and remove automatically generated valid usage statements now covered by the manual sections (public issue 383). * Clarify render pass compatibility for flink:vkCmdExecuteCommands (public issue 390). Internal Issues: * Update +vk.xml+ to make previously explicit valid usage statements for <<vkDebugReportMessageEXT,vkDebugReportMessageEXT>> implicit instead (internal issue 553). * Add valid usage statement for slink:VkCreateImageInfo preventing creation of 1D sparse images (internal issue 573). * Fix Python scripts to always read/write files in utf-8 encoding, and a logic error in reflib.py which could cause a fatal error for malstructured asciidoc (internal issues 578, 586).

Internal Issues: * Clarify for the <<features-features-shaderStorageImageExtendedFormats>> feature and in the <<spirvenv-capabilities-table>> that the feature means that all of the formats are supported, and that otherwise the features can be queried per-format (internal issue 1273). * Clarified interactions of `VK_EXT_external_memory_host` with host cache management commands and structures flink:vkMapMemory, flink:vkFlushMappedMemoryRanges, slink:VkMappedMemoryRange, and flink:vkUnmapMemory using the new glossary term "`Host Mapped Device Memory`" (internal issue 1385). * Update the language for flink:vkCreateViSurfaceNN.txt describing the pname:currentExtent of a VI surface to more accurately reflect current capabilities, replacing "`undefined`" with more explicit behavior (internal issue 1410). New Extensions: * `VK_EXT_calibrated_timestamps` * `VK_EXT_image_drm_format_modifier` (this extension was previously disabled in vk.xml, and has now been enabled after some changes to fix performance issues). * `VK_EXT_pci_bus_info` * `VK_EXT_transform_feedback` * `VK_GOOGLE_hlsl_functionality1`, exposing support for `SPV_GOOGLE_hlsl_functionality1`. * `VK_GOOGLE_decorate_string`, exposing support for `SPV_GOOGLE_decorate_string`.

Internal Issues: * Clarify in the `VK_KHR_surface` and `VK_KHR_swapchain` extensions that parameter combinations which aren't supported for normal images are also unsupported for presentable images, even if the parameter values are individually supported as reported by the surface capability queries (internal issue 1029). * Fixed XML typo in the valid value field of the pname:sType member of slink:VkPhysicalDeviceExternalMemoryHostPropertiesEXT (internal issue 1100). Other Issues: * Add memory semantics validity rules to the <<spirvenv-module-validation, Validation Rules within a Module>> section of the SPIR-V environment appendix, and specify that sequentiality consistency is not supported. This forbids certain cases like "`Load+Release`" that we don't expect to ever be meaningful. * Document mapping of OpenGL Shading Language barriers to SPIR-V scope and semantics in the `GL_KHR_vulkan_glsl` specification.

Change log for February 17, 2019 Vulkan 1.1.101 spec update: * Update release number to 101. Public Issues: * Make clear that memory types for imported host memory must be host visible in slink:VkMemoryHostPointerPropertiesEXT.txt (public issue 897). * Make <<interfaces-resources-layout, WARNING block>> into a NOTE block, per the styleguide (public pull request 916). Internal Issues: * Make <<textures-output-format-conversion, computation of derivatives in non-uniform flow control>> have undefined behavior (internal issue 1367). * Make behavior, not just values, undefined for <<textures-layout-validation, reads from inconsistent YCbCr layouts>> (internal issue 1366). * Consolidate version and extension behavior documentation in the <<extended-functionality, Extended Functionality>> appendix, While a great deal of text was moved from other parts of the Specification into the appendix, this just serves to simplify and make consistent discussions of versions and extensions (internal issue 1473). * Add limits for slink:VkPhysicalDeviceRayTracingPropertiesNV in the <<features-limits-types, Required Limit Types>> and <<features-limits-required, Required Limits>> tables (internal issue 1511). * Disallow <<memory-protected-memory, indirect calls within protected command buffers>> by adding valid usage statements for the related indirect dispatch and draw commands (internal issue 1513). * Add valid usage stataements to slink:VkGraphicsPipelineCreateInfo, slink:VkSubpassDescription, slink:VkSubpassDescription2KHR, slink:VkSubpassDescriptionDepthStencilResolveKHR, and slink:VkImageViewCreateInfo preventing the creation of a renderpass with attachments in formats that are not supported for rendering (internal issue 1552). * Qualify valid usage statements for slink:VkAttachmentReference::pname:layout parameter so restrictions only apply if an attachment is ename:VK_ATTACHMENT_UNUSED (internal issue 1561). * Add valid usage statement for flink:vkCmdDrawIndirectByteCountEXT restricting pname:vertexStride to be positive (internal issue 1566). * Make the `VK_EXT_sample_locations` extension depend on `VK_KHR_get_physical_device_properties2` in `vk.xml`. * Rearrange and simplify the <<interfaces-resources-layout, block layout rules>>. New Extensions: * `VK_NV_cooperative_matrix` * `VK_EXT_depth_clip_enable` (internal issue 1485).

Aliased Range (Memory)::
A range of a device memory allocation that is bound to multiple
resources simultaneously.
Change log for September 30, 2016 Vulkan 1.0.29 spec update: * Bump API patch number and header version number to 29 for this update. Github Issues: * Remove redundant constraint on slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue 224). * Fix typo and remove link in Note in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section (public issue 359). * Fix erroneous validation statement for the pname:layout member of slink:VkComputePipelineCreateInfo (public issue 362). Internal Issues: * Restore long figure captions using asciidoc sidebar blocks, due to restrictions of asciidoc syntax (internal issue 101). * Replace most latexmath equations with comparable markup in straight asciidoc, which significantly improves time required to fully load and process the HTML forms of the Specification. There are known minor font and alignment inconsistencies with MathJax and PDF rendering of latexmath equations. Please do not file github issues about these. We are aware of the inconsistencies and will make refinements over time, while the performance improvements are compelling in at least some major browsers (internal issue 313). * Move handcoded validity statements from +vk.xml+ into the Specification body, easing work in the single-branch model. Specify the distinction between these explicit statements, and the implicit validity statements inferred from vk.xml. Validity statements now appear in two blocks for each command and structure - handcoded "Valid Usage" and the implicit "Valid Usage (Implicit)" (internal issue 392). * Add the +returnedonly="false"+ attribute to WSI output structures, removing incorrectly generated implicit validity statements for slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR, slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR, slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures (internal issue 486). * Update slink:VkImageLayout to require the ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images (internal issue 487). * Use an explicit format specifier string for the date command invocation in the +Makefile+ instead of the shorthand -R option, which doesn't work on BSD and MaxOS X date commands (internal issue 500). Other Issues: * Use the terms ``allocation scope'' and ``extension scope'' instead of just ``scope'', and add them to the glossary.

Allocation Scope::
An association of a host memory allocation to a parent object or
command, where the allocation's lifetime ends before or at the same time
as the parent object is freed or destroyed, or during the parent
command.
Change log for June 24, 2016 Vulkan 1.0.18 spec update: * Bump API patch number and header version number to 18 for this update. Github Issues: * Added "queue operation" terminology, and modified spec to actually use this terminology (public issue 155). The act of submitting a piece of work to a queue now generates "operations" for the queue to execute, including operations to wait on/signal semaphores and fences. Synchronization waits on these operations, making execution dependency chains more obvious for semaphores and fences (though additional work is still needed here). These changes include: ** Overview of "queue submission" commands in chapter <<devsandqueues-submission>>. ** Updated descriptions for fence and semaphore waits and signals in the synchronization chapter <<synchronization-semaphores-waiting>>, <<synchronization-semaphores-signaling>> and <<synchronization-fences-waiting>>. ** Clarifications to semaphore and fence operation within queue submission functions. ** New glossary terms. ** Moved device idle and queue wait idle to synchronization chapter in order to describe them in terms of other synchronization primitives. ** Clarifications to semaphore and fence operation allowed removal of the "implicit ordering guarantees" section, as this information is now wholly covered where these primitives are described. *** The "host writes" section of this is still there for now - in its own section. This could probably be merged into other sections later. *** Modified fundamentals chapter on queue ordering to make sense in context of the new changes, and avoid duplication. <<fundamentals-queueoperation>> * Added "aspect" and "component" definitions to the glossary, and made sure these terms are referenced correctly (public issue 163). * Update valid usage for ftext:vkGet*ProcAddr to only include conditions that must be met to get a valid result. In particular, it's okay to call flink:vkGetDeviceProcAddr with any string and will get a code:NULL if that string is not a core Vulkan function or an enabled extension function (addresses but does not fully close public issue 214). * Change the WSI extension dependencies to refer to version 1.0 of the Vulkan API, instead of the pre-1.0-release internal revisions numbers (public issue 238). * Specified that <<interfaces-fragmentoutput,undeclared fragment shader outputs>> result in undefined values input to the blending unit or color attachment (public issue 240). Internal Issues: * Better documented that the registry XML "optional" tag for values only applies when that value is the size of an array (internal issue 335). * Add a stronger definition for the valid usages of VkSpecializationMapEntry.size in the <<pipelines-specialization-constants,Specialization Constants>> section (internal issue 345). * Change code:OpName to code:OpDecorate (along with appropriate syntax) for vertex shader built-ins (internal issue 368). * Add missing ref pages (those which are not currently stubs) to apispec.txt for the single-page version of the ref pages (internal issue 378). Other Commits: * Fix example in the <<descriptorsets,Descriptor Sets>> section to use M, N, and I, describing set, binding, and index, consistently throughout the example code.

Aspect (Image)::
An image may: contain multiple kinds, or aspects, of data for each
pixel, where each aspect is used in a particular way by the pipeline and
may: be stored differently or separately from other aspects.
For example, the color components of an image format make up the color
aspect of the image, and may: be used as a framebuffer color attachment.
Some operations, like depth testing, operate only on specific aspects of
an image.
Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for November 25, 2016 Vulkan 1.0.35 spec update: * Bump API patch number and header version number to 35 for this update. Github Issues: * Document in the <<memory-device-hostaccess,Host Access>> section that mapping and unmapping does not invalidate or flush the mapped memory (public issues 27, 126). * Redefine the entire <<synchronization>> chapter in terms of consistent and well defined terminology, that's called out at the start of the chapter. This terminology is applied equally to all synchronization types, including subpass dependencies, submissions, and much of the implicit ordering stuff dotted around the spec. Key terms are laid out in the <<synchronization-dependencies,Execution and Memory Dependencies>> section at the top of the rewritten chapter (public issues 128, 131, 132, 217, 299, 300, 302, 306, 322, 346, 347, 371, 407). * Specify order of submission for batches in the <<vkQueueSubmit,vkQueueSubmit>> and <<vkQueueBindSparse,vkQueueBindSparse>> commands (public issue 371). * Add valid usage statements to each of the WSI extension sections indicating that the WSI-specific structure parameters must be valid, and remove automatically generated valid usage statements now covered by the manual sections (public issue 383). * Clarify render pass compatibility for flink:vkCmdExecuteCommands (public issue 390). Internal Issues: * Update +vk.xml+ to make previously explicit valid usage statements for <<vkDebugReportMessageEXT,vkDebugReportMessageEXT>> implicit instead (internal issue 553). * Add valid usage statement for slink:VkCreateImageInfo preventing creation of 1D sparse images (internal issue 573). * Fix Python scripts to always read/write files in utf-8 encoding, and a logic error in reflib.py which could cause a fatal error for malstructured asciidoc (internal issues 578, 586).

Change log for December 1, 2016 Vulkan 1.0.36 spec update: * Bump API patch number and header version number to 36 for this update. Github Issues: * Fix "recorded with" terminology in the valid usage language for the flink:vkCmdExecuteCommands::pname:pCommandBuffers parameter (public issue 390). * Modify +genvk.py+ to support specifying extensions to remove from output generators, allowing the extension loader +vulkan_ext.c+ to be created without WSI extensions which are statically exported by the Vulkan loader (public issue 412). * Added validation language for slink:VkSubpassDependency and in the <<synchronization-access-types-supported,supported access types>> section to catch access masks that include bits which are not supported by pipeline stages in the stage masks (partially addresses public issue 1006). Internal Issues: * Added validation language for flink:vkCmdWaitEvents, flink:vkQueueSubmit, flink:VkRenderPassCreateInfo, and in the <<synchronization-pipeline-stages-supported>> section to prevent recording stage dependencies that aren't supported on the queue (internal issue 516). * Make a few changes that generalize spec language for use with possible future extensions by adding glossary terms and generalizing ``feature'' to ``feature or extension'' where relevant (internal issues 448, 590). * Added "pipeline type" attribute to +vk.xml+ for relevant commands and utilize it in automatic generation of the Command Properties table (internal issue 517). * Specify that WSI implementations must provide both UNORM and sRGB formats in the description of slink:VkColorSpaceKHR (internal issue 529). * Remove nesting of explicit valid usage statements where it is not meaningful (internal issue 583). Other Issues: * Add validity language requiring that slink:VkPushConstantRange::pname:offset be a multiple of 4, as stated in the spec language.

Change log for September 5, 2017 Vulkan 1.0.60 spec update: * Bump API patch number and header version number to 60 for this update. Github Issues: * Document that <<queries-timestamps, Timestamp Queries>> can only be meaningfully compared when they are written from the same queue (public issue 216). * Document that the `<extension>` tag `type` attribute is required for non-disabled extensions (derived from, but does not close public issue 354). * Clean up registry schema length attribute descriptions to be consistent and correct (public issue 555). Internal Issues: * Replace as much of the hand-written extension appendix metadata as possible with asciidoc includes generated from corresponding attributes of +vk.xml+, and enhance the style guide to match. This avoids inconsistencies between +vk.xml+ and the appendices, and produces a more uniform style (internal issue 137). * Remove the generated extDependency.{py,sh} files from the tree and create them dynamically on demand instead, reducing merge conflicts (internal issue 713). * Add a prototype tool for generating in-place difference markup for sections guarded by asciidoc conditionals, and new syntax for open blocks to support it (internal issue 833). * Remove unnecessary restriction of etext:*SYNC_FD_BIT_KHR external handle types to the same physical device in the slink:VkPhysicalDeviceIDPropertiesKHR, flink:VkImportMemoryWin32HandleInfoKHR, slink:VkImportFenceWin32HandleInfoKHR, slink:VkImportFenceFdInfoKHR, slink:VkImportSemaphoreWin32HandleInfoKHR, slink:VkImportSemaphoreFdInfoKHR <<external-memory-handle-types-compatibility, External memory handle types compatibility>>, <<external-semaphore-handle-types-compatibility, External semaphore handle types compatibility>>, and <<external-fence-handle-types-compatibility, External fence handle types compatibility>> sections (internal issue 956). Other Issues: * Remove dependency of +VK_KHX_device_group+ on +VK_KHR_swapchain+ (there is an interaction, but not a strict dependency), and add a new `extension` attribute to the `<require` XML tag to allow classifying a subset of interfaces of an extension as requiring another extension.

Change log for December 1, 2016 Vulkan 1.0.36 spec update: * Bump API patch number and header version number to 36 for this update. Github Issues: * Fix "recorded with" terminology in the valid usage language for the flink:vkCmdExecuteCommands::pname:pCommandBuffers parameter (public issue 390). * Modify +genvk.py+ to support specifying extensions to remove from output generators, allowing the extension loader +vulkan_ext.c+ to be created without WSI extensions which are statically exported by the Vulkan loader (public issue 412). * Added validation language for slink:VkSubpassDependency and in the <<synchronization-access-types-supported,supported access types>> section to catch access masks that include bits which are not supported by pipeline stages in the stage masks (partially addresses public issue 1006). Internal Issues: * Added validation language for flink:vkCmdWaitEvents, flink:vkQueueSubmit, flink:VkRenderPassCreateInfo, and in the <<synchronization-pipeline-stages-supported>> section to prevent recording stage dependencies that aren't supported on the queue (internal issue 516). * Make a few changes that generalize spec language for use with possible future extensions by adding glossary terms and generalizing ``feature'' to ``feature or extension'' where relevant (internal issues 448, 590). * Added "pipeline type" attribute to +vk.xml+ for relevant commands and utilize it in automatic generation of the Command Properties table (internal issue 517). * Specify that WSI implementations must provide both UNORM and sRGB formats in the description of slink:VkColorSpaceKHR (internal issue 529). * Remove nesting of explicit valid usage statements where it is not meaningful (internal issue 583). Other Issues: * Add validity language requiring that slink:VkPushConstantRange::pname:offset be a multiple of 4, as stated in the spec language.

Github Issues: * Fix "recorded with" terminology in the valid usage language for the flink:vkCmdExecuteCommands::pname:pCommandBuffers parameter (public issue 390). * Modify +genvk.py+ to support specifying extensions to remove from output generators, allowing the extension loader +vulkan_ext.c+ to be created without WSI extensions which are statically exported by the Vulkan loader (public issue 412). * Added validation language for slink:VkSubpassDependency and in the <<synchronization-access-types-supported,supported access types>> section to catch access masks that include bits which are not supported by pipeline stages in the stage masks (partially addresses public issue 1006). Internal Issues: * Added validation language for flink:vkCmdWaitEvents, flink:vkQueueSubmit, flink:VkRenderPassCreateInfo, and in the <<synchronization-pipeline-stages-supported>> section to prevent recording stage dependencies that aren't supported on the queue (internal issue 516). * Make a few changes that generalize spec language for use with possible future extensions by adding glossary terms and generalizing ``feature'' to ``feature or extension'' where relevant (internal issues 448, 590). * Added "pipeline type" attribute to +vk.xml+ for relevant commands and utilize it in automatic generation of the Command Properties table (internal issue 517). * Specify that WSI implementations must provide both UNORM and sRGB formats in the description of slink:VkColorSpaceKHR (internal issue 529). * Remove nesting of explicit valid usage statements where it is not meaningful (internal issue 583). Other Issues: * Add validity language requiring that slink:VkPushConstantRange::pname:offset be a multiple of 4, as stated in the spec language.

Change log for June 24, 2017 Vulkan 1.0.53 spec update: * Bump API patch number and header version number to 53 for this update. Github Issues: Internal Issues: * Clarify mappings of coordinates for mutable, compatible image views in slink:VkImageViewCreateInfo (internal issue 815). * Make ename:VK_BIND_SFR_BIT require a logical device with multiple physical devices, so that standard sparse image block dimensions are only required on systems that support multi-GPU (internal issue 835). * Convert all files from use of // refBegin .. // refEnd comments to delimit ref pages, to use of open blocks, and update style guide accordingly (internal issue 839). * Add valid usage for slink:VkWriteDescriptorSet when performing updates to a ename:VK_STORAGE_IMAGE descriptor with layout ename:VK_IMAGE_LAYOUT_GENERAL. * Add a hack to the validity generator script to support an odd interaction between flink:vkCmdFillBuffer and an extension (internal issue 853). * Remove redundant text describing slink:VkBufferCreateInfo::pname:usage, which was already covered by implicit valid usage (internal issue 854). * Update implicit validity generator script to properly handle the pname:sType and pname:pNext members of "returnedonly" structures (internal issue 874). * Note that slink:VkApplicationInfo::pname:pApplicationName & slink:VkApplicationInfo::pname:pEngineName are optional, and add missing implicit valid usage statements for flink:vkDestroyInstance. * Added missing valid usage for flink:vkCmdWriteTimestamp to require a timestamp query pool. * Simplify and/or split "`non-atomic`" valid usage statements. New Extensions: * `VK_AMD_gpu_shader_int16` * `VK_EXT_blend_operation_advanced` * `VK_EXT_sampler_filter_minmax` * `VK_NV_framebuffer_mixed_samples` ----------------------------------------------------- Note: the 1.0.52 spec wasn't published on github, so the 1.0.53 release combines both change sets. ----------------------------------------------------- Change log for June 13, 2017 Vulkan 1.0.52 spec update: * Bump API patch number and header version number to 52 for this update. Github Issues: Internal Issues: * Clarify behavior when non-coherent memory has <<memory-device-unmap-does-not-flush, not been flushed before being unmapped>> (internal issue 819). * Fix description of code:WorkgroupSize builtin to note it decorates an object, not a variable (internal issue 836). * Fix asciidoc attributes so that trailing '{plus}' symbols in [eq] style equations are rendered properly (internal issue 845). * Add language to the "`Extension Handles, Objects, Enums, and Typedefs`" section of the Procedures and Conventions document stating that any new handle type requires a corresponding entry in the elink:VkObjectType enumerated type (internal issue 856). * Update style guide to use slink macro for Vulkan handle type names, and define narrow conditions under which to use the *name and *text macros instead of *link (internal issue 886). * Add a dependency of the <<VK_KHX_device_group,VK_KHX_device_group>> extension on VK_KHX_device_group_creation to +vk.xml+ and the extension appendix. * Change the copyright on Vulkan specification asciidoc *source* files to CC-BY 4.0, and update the proprietary Khronos copyright applied to the generated *output* formats (internal issue 327). This enables broader re-use and modification of the Vulkan specification sources, while not affecting the Reciprocal IP License between Vulkan Adopters and Working Group Members. New Extensions: * `VK_NV_fill_rectangle` * `VK_NV_fragment_coverage_to_color`

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for January 23, 2017 Vulkan 1.0.39 spec update: * Bump API patch number and header version number to 39 for this update. Github Issues: * Clarified that only accesses via the specified buffer/image subresource ranges are included in the access scopes (public issue 306). * Add missing valid usage statements for flink:vkCreateComputePipelines and flink:vkCreateGraphicsPipelines (public issue 427). Internal Issues: * Add a Note to the <<invariance,Invariance>> appendix about a difference between OpenGL and Vulkan with regards to how primitives derived from offsets are handled (internal issue 355). * Add the +<<VK_KHR_get_physical_device_properties2>>+, +<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+ extensions (internal issue 448). * Add the +<<VK_EXT_shader_subgroup_vote>>+ and +<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449). * Update the texture level-of-detail equation in the <<textures-scale-factor,Scale Factor Operation>> section to better approximate the ellipse major and minor axes (internal issue 547). * Forbid non-explicitly allowed uses of interface decorations in the introduction to the <<interfaces,Shader Interfaces>> chapter (internal issue 607). * Replace use of MathJax with KaTeX, for improved load-time performance as well as avoiding the scrolling-and-scrolling behavior due to MathJax asynchronous rendering when loading at an anchor inside the spec. This change also requires moving to HTML5 output for the spec instead of XHTML, and there is a visible difference in that the chapter navigation index is now in a scrollable sidebar instead of at the top of the document. We may or may not retain the nav sidebar based on feedback (internal issue 613). * Improve consistency of markup and formatting in extension appendices (internal issue 631). Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage. If the swapchain has been replaced, then it should not be passed to flink:vkAcquireNextImage. * Add a valid usage statement to flink:vkCreateImageView, that the image must have been created with an appropriate usage bit set. * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section. * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor to account for the multiple viewport feature. If the feature is not enabled, the parameters for these functions have required values that are defined in the <<features-features-multiViewport,multiple viewports>> section of the spec but were not reflected in the valid usage text for these functions. * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common color spaces.

Change log for March 16, 2018 Vulkan 1.1.71 spec update: * First public update for Vulkan 1.1. Github Issues: * Refer to standard sparse image block shape format tables explicitly in the <<sparsememory-standard-shapes, Standard Sparse Image Block Shapes>> section (public issue 93). * Add the missing definition of the code:LocalInvocationIndex decoration in the <<interfaces-builtin-variables, Built-In Variables>> section (public issue 532). * Clarify dynamic state definition in the introduction to the <<pipelines, Pipelines>> section and the new <<pipelines-dynamic-state, Dynamic State>> subsection (public issue 620). * Clarified deprecation statement in the `VK_AMD_negative_viewport_height` appendix (public issue 674). * Fix parameter descriptions for flink:vkCreateIndirectCommandsLayoutNVX (public issue 677). Internal Issues: * Remove description of <<primsrast-points, rasterization point size>> being taken from the tessellation control shader, since there are no circumstances under which you can have TCS without TES (internal issue 522). * Define <<copies-images-format-size-compatibility, _size-compatible_ image formats>> for flink:vkCmdCopyImage, add it to the glossary, and use that definition for slink:VkImageViewCreateInfo (internal issue 771). * Change brief descriptions of enumerant names, and of parameters which are enumerants, from "`enum *indicates*`" to "`enum *specifies*`" for consistency, and add a markup style guide rule (internal issue 862). * Clarify how execution dependencies interact with <<synchronization-submission-order, submission order>> at numerous places in the <<renderpass, Render Pass>> and <<synchronization, Synchronization>> chapters (internal issue 1062). * Clarify statement in the <<interfaces-resources-setandbinding, DescriptorSet and Binding Assignment>> section that only interface variables statically used by the entry point used in a pipeline must be present in the descriptor set layout (internal issue 1172). * Flip sparse image diagrams with partially full mip levels vertically, to match graph origins of other image diagrams (internal issue 1176). * Update new SVG diagrams to have consistent style and base font size, increase consistency of primitive topology diagrams, and add a section to the style guide on creating and editing images in a consistent style (internal issue 1177). * Resolve problems with valid usage statement extraction by fixing existing VUID tags for interfaces promoted to version 1.1 and fixing conditional directives around VUID-VkMemoryDedicatedAllocateInfo-image-01797 (internal issue 1184). * Strip `KHR` suffixes from a few interfaces promoted to Vulkan 1.1 that were missed previously (internal issue 1185). * Restrict code:OpImageQuerySizeLod and code:OpImageQueryLevels to only work on code:Image operands with their code:Sampled operand set to 1. In other words, these operations are not defined to work with storage images (internal issue 1193). * Recycle extension slot for extension #82 in `vk.xml`. This extension was never published (internal issue 1195). * Add an issue to the `VK_KHR_maintenance1` appendix noting that zero height viewports are allowed when this extension is enabled (internal issue 1202). * Fix slink:VkDescriptorSetLayoutBinding description so that shader stages always use descriptor bindings, not the other way around (internal issue 1206). * Fix field name for slink:VkInputAttachmentAspectReference::pname:inputAttachmentIndex (internal issue 1210). Other Issues: * Fix a few broken links in the <<versions-1.1, Version 1.1>> appendix. * Replace a few old refBegin/refEnd tags with open block markup around interfaces, and remove old KHX VUID tags that were breaking the valid usage statement extraction. * Fix error codes accidentally tagged as success codes in `vk.xml` for flink:vkGetSwapchainCounterEXT. * Added valid usage statements for ftext:vkBind*Memory2 input structures stext:VkBind*MemoryInfo, and fix a pname:image -> pname:buffer typo in a couple of places. * Fix swapped descriptions of elink:VkDescriptorType enums ename:VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE and ename:VK_DESCRIPTOR_TYPE_STORAGE_IMAGE (reported via tweet).

Change log for September 30, 2016 Vulkan 1.0.29 spec update: * Bump API patch number and header version number to 29 for this update. Github Issues: * Remove redundant constraint on slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue 224). * Fix typo and remove link in Note in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section (public issue 359). * Fix erroneous validation statement for the pname:layout member of slink:VkComputePipelineCreateInfo (public issue 362). Internal Issues: * Restore long figure captions using asciidoc sidebar blocks, due to restrictions of asciidoc syntax (internal issue 101). * Replace most latexmath equations with comparable markup in straight asciidoc, which significantly improves time required to fully load and process the HTML forms of the Specification. There are known minor font and alignment inconsistencies with MathJax and PDF rendering of latexmath equations. Please do not file github issues about these. We are aware of the inconsistencies and will make refinements over time, while the performance improvements are compelling in at least some major browsers (internal issue 313). * Move handcoded validity statements from +vk.xml+ into the Specification body, easing work in the single-branch model. Specify the distinction between these explicit statements, and the implicit validity statements inferred from vk.xml. Validity statements now appear in two blocks for each command and structure - handcoded "Valid Usage" and the implicit "Valid Usage (Implicit)" (internal issue 392). * Add the +returnedonly="false"+ attribute to WSI output structures, removing incorrectly generated implicit validity statements for slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR, slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR, slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures (internal issue 486). * Update slink:VkImageLayout to require the ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images (internal issue 487). * Use an explicit format specifier string for the date command invocation in the +Makefile+ instead of the shorthand -R option, which doesn't work on BSD and MaxOS X date commands (internal issue 500). Other Issues: * Use the terms ``allocation scope'' and ``extension scope'' instead of just ``scope'', and add them to the glossary.

Change log for March 25, 2016 Vulkan 1.0.7 spec update: * Bump API patch number and header version number to 7 for this update. Github Issues: * Fix slink:VkSpecializationMapEntry example to avoid C/C++ strict aliasing issues (public issue 14). * Clarify the meaning of "matching" in flink:vkCmdBindDescriptorSets validity language (public issue 33). * Add stub reference pages so xrefs to not-yet-written pages don't generate 404 errors. However, the actual content of these pages still needs to be filled in as time allows (public issue 44, but does not close that issue out). * Remove incorrect validity statement for flink:vkGetImageSparseMemoryRequirements (public issue 85). * Reword the <<features-limits-bufferImageGranularity,bufferImageGranularity>> feature in terms of "aliasing", and clarify that it applies to bindings in the same memory object (public issue 90). * Clarify the relationship of the slink:VkPhysicalDeviceLimits pname:maxViewportDimensions and pname:viewportBoundsRange limits (public issue 92). * Specify sparse unbound texture replacement in the <<textures-texel-replacement,Texel Replacement>> section independently of robust buffer access language (public issue 100). * Add the <<fundamentals-architecture-model,Architecture Model>> section to explain architecture constraints Vulkan has chosen to accept in order to enable portable and performant code (public issue 122). * State that an object must not be destroyed until *all* (not *any*) uses of that object have completed (public issue 123). * Minor editorial cleanup (public issues 129, 134, 146, 148). * Add validity language for layer and extension names to slink:VkDeviceCreateInfo matching that used for slink:VkInstanceCreateInfo (public issue 130). * Clean up terminology for the case when the bits set in one bitmask are a subset of the bits set in another bitmask (public issue 138). * Document that input attachments are UniformConstant not Input, in the <<interfaces-inputattachment,Fragment Input Attachment Interface>> section (public glslang bug 169). Internal Issues: * Add max enum values to "flag bits" enums (internal issue #136). * Clarify language around the various uses of the term "block" in the <<appendix-compressedtex-bc,Block Compressed Image Formats>> section (internal issue #202). * Removed "expand" dependency from <enums> groups in vk.xml and added auto-generation code in the scripts to infer it instead, to ensure consistency. This caused renaming of sname:VkColorSpaceKHR and sname:VkPresentModeKHR etext:BEGIN_RANGE (etc.) tokens, but those tokens are metadata, not part of the API, and the Vulkan WG is OK with this change. This change adds ranges to two additional enums that were missing them due to not defining the "expand" attribute (internal issue 217). * Tweak makefile to generate ref page nroff (.3) files in the right output directory, working around an a2x limitation (internal issue 223). Other Commits: * Add validity requirements for flink:vkCmdCopyQueryPoolResults pname:dstBuffer parameter. * Fix ref page build to generate .3 targets in the right output directory.

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Github Issues: * Clarified that only accesses via the specified buffer/image subresource ranges are included in the access scopes (public issue 306). * Add missing valid usage statements for flink:vkCreateComputePipelines and flink:vkCreateGraphicsPipelines (public issue 427). Internal Issues: * Add a Note to the <<invariance,Invariance>> appendix about a difference between OpenGL and Vulkan with regards to how primitives derived from offsets are handled (internal issue 355). * Add the +<<VK_KHR_get_physical_device_properties2>>+, +<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+ extensions (internal issue 448). * Add the +<<VK_EXT_shader_subgroup_vote>>+ and +<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449). * Update the texture level-of-detail equation in the <<textures-scale-factor,Scale Factor Operation>> section to better approximate the ellipse major and minor axes (internal issue 547). * Forbid non-explicitly allowed uses of interface decorations in the introduction to the <<interfaces,Shader Interfaces>> chapter (internal issue 607). * Replace use of MathJax with KaTeX, for improved load-time performance as well as avoiding the scrolling-and-scrolling behavior due to MathJax asynchronous rendering when loading at an anchor inside the spec. This change also requires moving to HTML5 output for the spec instead of XHTML, and there is a visible difference in that the chapter navigation index is now in a scrollable sidebar instead of at the top of the document. We may or may not retain the nav sidebar based on feedback (internal issue 613). * Improve consistency of markup and formatting in extension appendices (internal issue 631). Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage. If the swapchain has been replaced, then it should not be passed to flink:vkAcquireNextImage. * Add a valid usage statement to flink:vkCreateImageView, that the image must have been created with an appropriate usage bit set. * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section. * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor to account for the multiple viewport feature. If the feature is not enabled, the parameters for these functions have required values that are defined in the <<features-features-multiViewport,multiple viewports>> section of the spec but were not reflected in the valid usage text for these functions. * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common color spaces.

Minor re-wording to avoid "color space" when actively incorrect, now that we refer to the Data Format Spec which actually makes a distinction between color space and transfer function (public issue 94). * Treat pname:pPropertyCount == 0 consistently in flink:vkEnumerateInstanceLayerProperties and flink:vkEnumerateDeviceLayerProperties (public issue 99) * Cleanup minor editorial issues in chapters 14-17 (public issue 100). * Clarify definition of flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties (public issue 101). * Define the flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties pname:pLayerName parameter to be a pointer to a null-terminated UTF-8 string (public issue 101). * Rearrange "Missing information" references in mandatory format tables (public issue 101). * Clarify that the enumerated extensions returned by flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties will only include extensions provided by the platform or extensions implemented in implicitly enabled layers (public issue 101). * Miscellaneous editorial fixes. Include the Vulkan spec patch number in the PDF title. Fix label on &lt;&lt;fig-non-strict-lines,Non strict lines>> diagram. Use more easily distinguished symbols in tables in the &lt;&lt;features-required-format-support,Required Format Support>> section.

Previously spec only referred to the members of pname:pCommandBuffers being affected by this bit. Added a separate slink:VkSubmitInfo Valid Usage restriction specifying that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT also applies to any secondary command buffers that are recorded into the primary command buffers in pname:pCommandBuffers (internal issue 106). * Clarify that slink:VkDeviceCreateInfo::pname:pEnabledFeatures can be NULL (internal issue 117). * Remove "the value of" where it is redundant (e.g. speaking of an API parameter, struct member, or SPIR-V variable, but not when speaking of color components) (internal issue 175). * Forced patch version to always be 0 in the header. Add a "VK_API_VERSION_<major>_<minor>" macro for people to use to do the right thing. Add a VK_HEADER_VERSION which captures the header release number independent of the spec patch number (internal issue 176). * Correct description of slink:VkPipelineShaderStageCreateInfo::pname:pName to "a pointer to a null-terminated UTF-8 string" (internal issue #197). Other Commits: * Updated DataFormat spec reference to the new date for revision 5 of that spec. * Fixed KEEP option (to retain LaTeX intermediate files) in the Makefile to be included when edited there, as well as set on the command line. * Reserve and add "VK_IMG_filter_cubic" to the registry, and implement script functionality to add and remove validity from existing functions. Includes schema and readme changes. * Update GL_KHR_vulkan_glsl so push_constants do not have descriptor sets.

Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

This change also requires moving to HTML5 output for the spec instead of XHTML, and there is a visible difference in that the chapter navigation index is now in a scrollable sidebar instead of at the top of the document. We may or may not retain the nav sidebar based on feedback (internal issue 613). * Improve consistency of markup and formatting in extension appendices (internal issue 631). Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage.

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported.

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2.

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for January 23, 2017 Vulkan 1.0.39 spec update: * Bump API patch number and header version number to 39 for this update. Github Issues: * Clarified that only accesses via the specified buffer/image subresource ranges are included in the access scopes (public issue 306). * Add missing valid usage statements for flink:vkCreateComputePipelines and flink:vkCreateGraphicsPipelines (public issue 427). Internal Issues: * Add a Note to the <<invariance,Invariance>> appendix about a difference between OpenGL and Vulkan with regards to how primitives derived from offsets are handled (internal issue 355). * Add the +<<VK_KHR_get_physical_device_properties2>>+, +<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+ extensions (internal issue 448). * Add the +<<VK_EXT_shader_subgroup_vote>>+ and +<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449). * Update the texture level-of-detail equation in the <<textures-scale-factor,Scale Factor Operation>> section to better approximate the ellipse major and minor axes (internal issue 547). * Forbid non-explicitly allowed uses of interface decorations in the introduction to the <<interfaces,Shader Interfaces>> chapter (internal issue 607). * Replace use of MathJax with KaTeX, for improved load-time performance as well as avoiding the scrolling-and-scrolling behavior due to MathJax asynchronous rendering when loading at an anchor inside the spec. This change also requires moving to HTML5 output for the spec instead of XHTML, and there is a visible difference in that the chapter navigation index is now in a scrollable sidebar instead of at the top of the document. We may or may not retain the nav sidebar based on feedback (internal issue 613). * Improve consistency of markup and formatting in extension appendices (internal issue 631). Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage. If the swapchain has been replaced, then it should not be passed to flink:vkAcquireNextImage. * Add a valid usage statement to flink:vkCreateImageView, that the image must have been created with an appropriate usage bit set. * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section. * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor to account for the multiple viewport feature. If the feature is not enabled, the parameters for these functions have required values that are defined in the <<features-features-multiViewport,multiple viewports>> section of the spec but were not reflected in the valid usage text for these functions. * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common color spaces.

Github Issues: * Clarify that integer border values are meant to be 0/1, and that integer texture lookups are sign-extended in the <<textures-format-conversion,Format Conversion>> and <<textures-texel-replacement,Texel Replacement>> sections (public issue 52). * Add logic to generate spec boilerplate without using the 'git' command-line client, needed when building from a tarball or another source of the Vulkan tree rather than a cloned git repo. Remove boilerplate as part of 'clean' target (public issue 195). * Document that color writes and clears to unused attachments have no effect for slink:VkClearAttachment and elink:VkColorComponentFlagBits (public issue 198). * Fixed flink:vkCmdExecuteCommands validity statement for sname:VkCommandBufferInheritanceInfo::pname:framebuffer. If used, it must match the framebuffer in the current renderpass instance (public issue 226). * Added valid usage language to require for all functions that set dynamic state that the currently bound graphics pipeline has the corresponding dynamic state enabled (public issue 235). Internal Issues: * Clarify for flink:vkEnumerateInstanceExtensionProperties, in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section, and in the <<glossary,Glossary>> section when functionality should be exposed as an instance extension, as a device extension, or as both (internal issue 109). * Place WorkgroupSize in alphabetical order in the <<interfaces-builtin-variables,Built-in Variables>> section (internal issue 323). * Corrects valid usage in vkEndRenderPass to only affect primary render passes, as secondaries may be entirely within a render pass, and should be able to be ended (previous language disallowed that) (internal issue 338). * Fix relational operator from <= to >= in the <<features-extentperimagetype,Allowed Extent Values>> section (internal issue 343). * Disallow recursion under SPIR-V entry points in the <<spirvenv-module-validation,Validation Rules within a Module>> section (internal SPIR-V issue 37). Other Commits: * Use standard Python ElementTree package instead of lxml.etree in header / validation layer / include autogeneration from XML, reducing platform dependencies.

Device-Level Object::
Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Change log for December 1, 2016 Vulkan 1.0.36 spec update: * Bump API patch number and header version number to 36 for this update. Github Issues: * Fix "recorded with" terminology in the valid usage language for the flink:vkCmdExecuteCommands::pname:pCommandBuffers parameter (public issue 390). * Modify +genvk.py+ to support specifying extensions to remove from output generators, allowing the extension loader +vulkan_ext.c+ to be created without WSI extensions which are statically exported by the Vulkan loader (public issue 412). * Added validation language for slink:VkSubpassDependency and in the <<synchronization-access-types-supported,supported access types>> section to catch access masks that include bits which are not supported by pipeline stages in the stage masks (partially addresses public issue 1006). Internal Issues: * Added validation language for flink:vkCmdWaitEvents, flink:vkQueueSubmit, flink:VkRenderPassCreateInfo, and in the <<synchronization-pipeline-stages-supported>> section to prevent recording stage dependencies that aren't supported on the queue (internal issue 516). * Make a few changes that generalize spec language for use with possible future extensions by adding glossary terms and generalizing ``feature'' to ``feature or extension'' where relevant (internal issues 448, 590). * Added "pipeline type" attribute to +vk.xml+ for relevant commands and utilize it in automatic generation of the Command Properties table (internal issue 517). * Specify that WSI implementations must provide both UNORM and sRGB formats in the description of slink:VkColorSpaceKHR (internal issue 529). * Remove nesting of explicit valid usage statements where it is not meaningful (internal issue 583). Other Issues: * Add validity language requiring that slink:VkPushConstantRange::pname:offset be a multiple of 4, as stated in the spec language.

Internal Issues: * Add the <<fundamentals-abi,Application Binary Interface>> section describing platform ABI requirements and recommendations, add examples of function and function pointer declarations to the <<boilerplate-platform-specific-calling-conventions, Platform-Specific Calling Conventions>> section, and remove related language that existed elsewhere in the specification (internal issue 64). * Describe where to document valid usage interactions of chained structures in the style guide, and fix one case now appearing in slink:VkBufferCreateInfo instead of the child slink:VkDedicatedAllocationBufferCreateInfoNV structure (internal issue 715). * Add example to the style guide of describing enumerated types which are empty when the spec is built without relevant extensions enabled, and apply it to existing examples for elink:VkDescriptorSetLayoutCreateFlagBits and elink:VkSubpassDescriptionFlagBits (internal issue 864). * Add a note to the <<fundamentals-validusage-enums, Valid Usage for Enumerated Types>> section that the special values suffixed with etext:_BEGIN_RANGE, etext:_END_RANGE, etext:_RANGE_SIZE and etext:_MAX_ENUM are not part of the API and should: not be used by applications (internal issue 872). * Added note to flink:vkCmdUpdateBuffers explaining the performance penalty for copies done in this way, and why the upper copy limit is what it is (internal issue 952). * Update `VK_KHX_device_group` to split some functionality into the new `VK_KHR_bind_memory2` extension, and rename that functionality (internal issue 969). * Remove *Status* fields from extension appendices, since they are by definition published and complete by the time they reach the public github repository (internal issue 973). Other Issues: * Update Data Format specification dependency to version 1.2 and change references to DF sections accordingly. * Update XML to make the pname:pAllocator parameter of flink:vkRegisterDeviceEventEXT and flink:vkRegisterDisplayEventEXT in the `VK_EXT_display_control` extension as optional.

Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Internal Issues: * Add the <<fundamentals-abi,Application Binary Interface>> section describing platform ABI requirements and recommendations, add examples of function and function pointer declarations to the <<boilerplate-platform-specific-calling-conventions, Platform-Specific Calling Conventions>> section, and remove related language that existed elsewhere in the specification (internal issue 64). * Describe where to document valid usage interactions of chained structures in the style guide, and fix one case now appearing in slink:VkBufferCreateInfo instead of the child slink:VkDedicatedAllocationBufferCreateInfoNV structure (internal issue 715). * Add example to the style guide of describing enumerated types which are empty when the spec is built without relevant extensions enabled, and apply it to existing examples for elink:VkDescriptorSetLayoutCreateFlagBits and elink:VkSubpassDescriptionFlagBits (internal issue 864). * Add a note to the <<fundamentals-validusage-enums, Valid Usage for Enumerated Types>> section that the special values suffixed with etext:_BEGIN_RANGE, etext:_END_RANGE, etext:_RANGE_SIZE and etext:_MAX_ENUM are not part of the API and should: not be used by applications (internal issue 872). * Added note to flink:vkCmdUpdateBuffers explaining the performance penalty for copies done in this way, and why the upper copy limit is what it is (internal issue 952). * Update `VK_KHX_device_group` to split some functionality into the new `VK_KHR_bind_memory2` extension, and rename that functionality (internal issue 969). * Remove *Status* fields from extension appendices, since they are by definition published and complete by the time they reach the public github repository (internal issue 973). Other Issues: * Update Data Format specification dependency to version 1.2 and change references to DF sections accordingly. * Update XML to make the pname:pAllocator parameter of flink:vkRegisterDeviceEventEXT and flink:vkRegisterDisplayEventEXT in the `VK_EXT_display_control` extension as optional. New Extensions: * `VK_KHR_bind_memory2` * `VK_KHR_image_format_list` * `VK_KHR_maintenance2` * `VK_KHR_sampler_ycbcr_conversion`

We are now using the Ruby-based ``asciidoctor'' implementation, rather than the Python-based ``asciidoc'' implementation, to process the specification. While the actual specification markup changes were minimal, this requires a new set of build tools and a very different installation process, especially because we now use an experimental direct-to-PDF backend for Asciidoctor instead of Docbook->dblatex->PDF. It is no longer possible to build the Specification using asciidoc. See doc/specs/vulkan/README.adoc for some guidance on installing the new toolchain components. * There are some minor rendering issues in the PDF output due to teething problems with the asciidoctor toolchain, especially with mathematical equations. We are aware of these and working on them. Github Issues: * Updated sample code for the <<sparsememory-examples-basic,sparse resource binding example>> (public issue 97). * Modify line and point clipping behavior in the <<vertexpostproc-clipping, Primitive Clipping>> section to allow for pop-free behavior. The ability to check for which behavior is implemented may be added a future feature or extension (public issue 113). * Unify the discussions of implicit ordering throughout the spec, in particular in the new sections <<drawing-primitive-order, Primitive Order>>, <<primrast-order, Rasterization Order>>, and <<synchronization-implicit, Implicit Synchronization Guarantees>>; the discussion of <<synchronization-submission-order, submission order>>; and references elsewhere to these sections (public issue 133). * Clarify \<\<descriptorsets-compatibility,Pipeline Layout Compatibility>> language and introduce the term ``identically defined'' (public issue 164). * Add a dependency to the +VK_EXT_debug_marker+ extension that's needed to reuse the object type enum from +VK_EXT_debug_report+, and moves the definition of that enum into +VK_EXT_debug_report+ where it should be (public issue 409). * Remove redundant valid usage statement from slink:VkImageBlit (public issue 421). * Update GL_KHR_vulkan_glsl to allow the ternary operator to result in a specialization constant (public issue 424). * Fix valid usage for flink:VkPipelineShaderStageCreateInfo (public issue 426). * Correct typo in New Objects list for <<VK_EXT_debug_report>> (public issue 447). Internal Issues: * Moved to asciidoctor for spec builds (internal issue 121). * Update style guide to describe where to put new extensions-specific asciidoc files, and what to name them (internal issue 626). * Add src/spec/indexExt.py to autogenerate registry index entries linking into the 1.0-extensions specification, instead of maintaining the index manually. (internal issue 642). * Autogenerate extension dependencies and lists of all extensions and all KHR extensions from the "supported" attributes in +vk.xml+. Execute +make config/extDependency.sh+ from +doc/specs/vulkan+ when a supported extension is added to vk.xml, to regenerate the dependency script. The consequence is that specifying a single extension to the +makeExt+ script will automatically enable all extensions it depends on as well, and that the +makeAllExts+ and +makeKHR+ scripts do not need to be updated when a new extension is supported (internal issue 648). * Put extension appendices all at the same asciidoc section level, so KHR WSI extensions show up in the HTML index (internal issue 648). Other Issues: * Imbed images in the generated HTML specs instead of loading them from the images/ directory. * Fix missing EXT in extension name (ename:VK_EXT_SWAPCHAIN_COLOR_SPACE_EXTENSION_NAME). * Add new +VK_EXT_SMPTE_2086_metadata+ extension. * In the <<platformCreateSurface_xlib,Xlib Surface>> section of the +VK_KHR_xlib_surface+ specification, add language warning users that they always need to call code:XinitThreads. * Use the term "presentable image" (rather than "swapchain image") consistently in +VK_KHR_swapchain+ and related extensions, and add a glossary term defining it. * Relocate the valid usage for samples of flink:vkGetPhysicalDeviceSparseImageFormatProperties2KHR::pname:pFormatInfo to be below the flink:VkPhysicalDeviceSparseImageFormatInfo2KHR structure.

Change log for October 14, 2016 Vulkan 1.0.31 spec update: * Bump API patch number and header version number to 31 for this update. Github Issues: * Clarifying wording of slink:VkGraphicsPipelineCreateInfo parameters and adding Valid Usage statements on render pass compatibility to the <<drawing,drawing commands>> (public issue 375). * Replace 'texel size' with 'element size', and add a definition to the glossary (public issue 382). * Clarify the description of ename:VK_ERROR_NATIVE_WINDOW_IN_USE_KHR to make it accurate, but still generic (non-exhaustive). Remove two Valid Usage statements describing error situations that will return ename:VK_ERROR_NATIVE_WINDOW_IN_USE_KHR (public issue 387). * Fix refBegin tag for elink:VkDebugReportFlagBitsEXT (public issue 392). * The <<interfaces-builtin-variables,built-in variable>> code:PrimitiveId in a fragment shader needs the code:Input storage class (public issue 393). Internal Issues: * Unused ({y,z} and {height,depth} for 1D, z and depth for 2D) offsets must be 0 and unused extents must be 1. Added basic offset and extent valid usage for slink:VkImageResolve to match that of slink:VkImageCopy (internal issue 413). * Describe what flink:vkGetPhysicalDeviceImageFormatProperties returns for pname:sampleCounts when for pname:usage only includes transfer-related flags (internal issue 478). * Remove mention of slink:VkPhysicalDeviceLimits::pname:maxImageArrayLayers from the valid usage for slink:VkImageCreateInfo::pname:arrayLayers (internal issue 520). * Tag usages of ``dynamically uniform'' as glossary terms and add a glossary entry pointing to the SPIR-V Specification's definition of the term (internal issue 531).

Change log for April 22, 2016 Vulkan 1.0.11 spec update: * Bump API patch number and header version number to 11 for this update. Github Issues: * Clarify the WSI extension language by switching from the fuzzier "ownership" language to more-consistent "acquire" language (public issue 117). * Clarify that memory barriers apply to all commands in the dependency chains in the flink:vkGetRenderAreaGranularity command and the <<synchronization-execution-and-memory-dependencies,Execution And Memory Dependencies>> section (public issue 132). * Clarify that a queue family is a set of queues in the <<fundamentals-execmodel,Execution Model>> section (public issue 166). * Removed requirement from valid usage language that VkPresentInfoKHR::waitSemaphoreCount must be greater than 0 (public issue 171). * Fix broken internal links, describe structures consistently, use consistent style for SPIR-V codewords, and tag normative terms that were missing asciidoc tags (public issue 183 and ancillary markup/normative language fixes). * Fix typos for slink:VkPhysicalDeviceLimits member names in slink:VkImageCreateInfo validity language (public issue 184). Internal Issues: * Document that the requested patch version number specified as part of slink:VkApplicationInfo::pname:apiVersion is ignored when creating an instance (internal issue 176). * Clarify handling of extension structs in the <<fundamentals-validusageValid Usage>> section (internal issue 254). * Update required slink:VkImageFormatProperties::pname:maxMipLevels to be limited to the maximum allowed mipmap pyramid size corresponding to the actual maximum supported size for the format (internal issue 256). * Modify the <<features-extentperimagetype,Allowed Extent Values Based On Image Type>> section so the allowed maximum extent is the maximum image dimension supported for each dimension of the type of texture being queried (internal issue 257). * Clarify in the <<spirvenv-module-validation,Validation Rules within a Module>> section that at least one of the code:LocalSize execution mode or code:WorkgroupSize decoration is required for each compute shader entry point in a shader module (internal issue 279). * Add validity rules for formats in flink:vkCmdClearColorImage and flink:vkCmdClearDepthStencilImage (internal issue 283). * Clarify that slink:VkImageFormatProperties::pname:maxResourceSize is an upper bound, and that it may not be possible to create an image anywhere near that size (internal issue 284). Other Commits: * Fix various minor markup errors reported by validation scripts. * Change copyright from Khronos Free Use License to Apache 2.0 license on relevant script/XML/header files. This does not affect the specification source copyright.

Change log for May 13, 2016 Vulkan 1.0.13 spec update: * Bump API patch number and header version number to 13 for this update. Github Issues: * Improve the description of ename:VK_PRESENT_MODE_FIFO_RELAXED_KHR in the VK_KHR_surface extension (public issue 174). * Clarify use of etext:*_SIMULTANEOUS_USE_BIT for secondary command buffers (public issue 182). * Fix typos in VK_KHR_wayland_surface extension where code:wl_device was used instead of code:wl_display (public issue 193). * Replaced {apiname} with ``Vulkan'' in XML validity statements (public issue 199). * Fix dead links for WSI handle types (public issue 200). *** N.b. this needs to be done in WSI branches as well *** * Use "signaled" instead of "signalled" spelling everywhere (public issue 201). *** N.b. this needs to be done in WSI branches as well *** * Move readme.pdf target directory for XML schema documentation into the target generation directory, instead of leaving it checked into the spec source tree (public issue 203). *** N.b. need to add generated PDF to registry index/1.0 page * Fix duplicate 'which which' typo in description of elink:VkCommandPoolResetFlagBits (public issue 204). * Move the <<Programmable Primitive Shading>> section up one level, out of the <<drawing-primitive-topologies,Primitive Topologies>> section (public issue 209). Internal Issues: * Clarify in the <<pipelines-cache,Pipeline Cache>> section that implementations should not manage the size of pipeline cache (internal issue 192). * Deprecate the concept of device layers and associated commands (internal issue 255). * Remove ename:VK_INCOMPLETE from the list of possible result codes of flink:vkGetPhysicalDeviceSurfaceCapabilitiesKHR (internal issue 314). * Add missing std140/std430 rule: the base alignment of a member following a structure is a multiple of the structure's base alignment (internal issue 321). * Fixes naming of the single elink:VkColorSpaceKHR enum from ename:VK_COLORSPACE_SRGB_NONLINEAR_KHR to ename:VK_COLOR_SPACE_SRGB_NONLINEAR_KHR in XML/header and the VK_KHR_swapchain and VK_KHR_surface extensions to match the style of the typename (space and color are two words, not one) (internal issue 322). * Make it clear that code:LocalInvocationID should only be applied to an input variable and normalize the language describing code:LocalInvocationID to the language for other compute shader variables in the <<interfaces-builtin-variables,Built-in Variables>> section, and add normative language (internal issue 323). * Clarify in the <<fundamentals-returncodes,Return Codes>> section that the result pointer may be modified for specific commands, even if a runtime error is returned (internal issue 324).

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for January 23, 2017 Vulkan 1.0.39 spec update: * Bump API patch number and header version number to 39 for this update. Github Issues: * Clarified that only accesses via the specified buffer/image subresource ranges are included in the access scopes (public issue 306). * Add missing valid usage statements for flink:vkCreateComputePipelines and flink:vkCreateGraphicsPipelines (public issue 427). Internal Issues: * Add a Note to the <<invariance,Invariance>> appendix about a difference between OpenGL and Vulkan with regards to how primitives derived from offsets are handled (internal issue 355). * Add the +<<VK_KHR_get_physical_device_properties2>>+, +<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+ extensions (internal issue 448). * Add the +<<VK_EXT_shader_subgroup_vote>>+ and +<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449). * Update the texture level-of-detail equation in the <<textures-scale-factor,Scale Factor Operation>> section to better approximate the ellipse major and minor axes (internal issue 547). * Forbid non-explicitly allowed uses of interface decorations in the introduction to the <<interfaces,Shader Interfaces>> chapter (internal issue 607). * Replace use of MathJax with KaTeX, for improved load-time performance as well as avoiding the scrolling-and-scrolling behavior due to MathJax asynchronous rendering when loading at an anchor inside the spec. This change also requires moving to HTML5 output for the spec instead of XHTML, and there is a visible difference in that the chapter navigation index is now in a scrollable sidebar instead of at the top of the document. We may or may not retain the nav sidebar based on feedback (internal issue 613). * Improve consistency of markup and formatting in extension appendices (internal issue 631). Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage. If the swapchain has been replaced, then it should not be passed to flink:vkAcquireNextImage. * Add a valid usage statement to flink:vkCreateImageView, that the image must have been created with an appropriate usage bit set. * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section. * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor to account for the multiple viewport feature. If the feature is not enabled, the parameters for these functions have required values that are defined in the <<features-features-multiViewport,multiple viewports>> section of the spec but were not reflected in the valid usage text for these functions. * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common color spaces.

Change log for November 25, 2016 Vulkan 1.0.35 spec update: * Bump API patch number and header version number to 35 for this update. Github Issues: * Document in the <<memory-device-hostaccess,Host Access>> section that mapping and unmapping does not invalidate or flush the mapped memory (public issues 27, 126). * Redefine the entire <<synchronization>> chapter in terms of consistent and well defined terminology, that's called out at the start of the chapter. This terminology is applied equally to all synchronization types, including subpass dependencies, submissions, and much of the implicit ordering stuff dotted around the spec. Key terms are laid out in the <<synchronization-dependencies,Execution and Memory Dependencies>> section at the top of the rewritten chapter (public issues 128, 131, 132, 217, 299, 300, 302, 306, 322, 346, 347, 371, 407). * Specify order of submission for batches in the <<vkQueueSubmit,vkQueueSubmit>> and <<vkQueueBindSparse,vkQueueBindSparse>> commands (public issue 371). * Add valid usage statements to each of the WSI extension sections indicating that the WSI-specific structure parameters must be valid, and remove automatically generated valid usage statements now covered by the manual sections (public issue 383). * Clarify render pass compatibility for flink:vkCmdExecuteCommands (public issue 390). Internal Issues: * Update +vk.xml+ to make previously explicit valid usage statements for <<vkDebugReportMessageEXT,vkDebugReportMessageEXT>> implicit instead (internal issue 553). * Add valid usage statement for slink:VkCreateImageInfo preventing creation of 1D sparse images (internal issue 573). * Fix Python scripts to always read/write files in utf-8 encoding, and a logic error in reflib.py which could cause a fatal error for malstructured asciidoc (internal issues 578, 586).

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter.

Explicit chroma reconstruction::
An implementation of sampler Y'C~B~C~R~ conversion which reconstructs
reduced-resolution chroma samples to luma resolution and then separately
performs texture sample interpolation.
This is distinct from an implicit implementation, which incorporates
chroma sample reconstruction into texture sample interpolation.
Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation.

Change log for September 30, 2016 Vulkan 1.0.29 spec update: * Bump API patch number and header version number to 29 for this update. Github Issues: * Remove redundant constraint on slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue 224). * Fix typo and remove link in Note in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section (public issue 359). * Fix erroneous validation statement for the pname:layout member of slink:VkComputePipelineCreateInfo (public issue 362). Internal Issues: * Restore long figure captions using asciidoc sidebar blocks, due to restrictions of asciidoc syntax (internal issue 101). * Replace most latexmath equations with comparable markup in straight asciidoc, which significantly improves time required to fully load and process the HTML forms of the Specification. There are known minor font and alignment inconsistencies with MathJax and PDF rendering of latexmath equations. Please do not file github issues about these. We are aware of the inconsistencies and will make refinements over time, while the performance improvements are compelling in at least some major browsers (internal issue 313). * Move handcoded validity statements from +vk.xml+ into the Specification body, easing work in the single-branch model. Specify the distinction between these explicit statements, and the implicit validity statements inferred from vk.xml. Validity statements now appear in two blocks for each command and structure - handcoded "Valid Usage" and the implicit "Valid Usage (Implicit)" (internal issue 392). * Add the +returnedonly="false"+ attribute to WSI output structures, removing incorrectly generated implicit validity statements for slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR, slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR, slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures (internal issue 486). * Update slink:VkImageLayout to require the ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images (internal issue 487). * Use an explicit format specifier string for the date command invocation in the +Makefile+ instead of the shorthand -R option, which doesn't work on BSD and MaxOS X date commands (internal issue 500). Other Issues: * Use the terms ``allocation scope'' and ``extension scope'' instead of just ``scope'', and add them to the glossary.

External Handle::
A resource handle which has meaning outside of a specific Vulkan device
or its parent instance.
External handles may: be used to share resources between multiple Vulkan
devices in different instances, or between Vulkan and other APIs.
Some external handle types correspond to platform-defined handles, in
which case the resource may: outlive any particular Vulkan device or
instance and may: be transferred between processes, or otherwise
manipulated via functionality defined by the platform for that handle
type.

Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Change log for April 8, 2017 Vulkan 1.0.47 spec update: * Bump API patch number and header version number to 47 for this update. Github Issues: * Allow <<synchronization-pipeline-barriers-subpass-self-dependencies, self-dependencies>> (also described for slink:VkSubpassDependency) to have earlier stages depend on later stages if all stages are framebuffer-space (public issue 125). * Clarify when pipeline state structures are ignored in the slink:VkGraphicsPipelineCreateInfo strucure, when the tessellation structure must be valid, and remove 'if `NULL`' descriptions from the valid usage statements (public issue 445). * Remove the obsolete "validextensionstructs" attribute for flink:VkPresentRegionsKHR. This caused a pname:pNext valid usage statement to be generated which wasn't consistent with what is stated in the spec (public issue 481). Internal Issues: * Clarify facingness of non-polygon fragments for slink:VkStencilOpState and in the code:FrontFacing <<interfaces-builtin-variables,built-in variable description>>. Define 'facingness' of a fragment as a distinct term from facingness of a polygon (internal issue 662). * Clarify that the texture compression features (e.g. pname:textureCompressionBC) means that all formats of that type (<<features-features-textureCompressionASTC_LDR,ASTC>>, <<features-features-textureCompressionETC2,ETC2>>, <<features-features-textureCompressionBC,BC>>) are supported, and that support for individual formats may: queried separately (internal issue 663). * Clarify in the valid usage for slink:VkBindImageMemoryInfoKHX that each SFR rectangle must be a multiple of the sparse block size for each aspect, e.g. in a depth/stencil image using separate depth/stencil planes (internal issue 721). * Re-remove KHX variants of KHR structure types after promotion (internal issue 762).

Internal Issues: * Add a Note to the <<invariance,Invariance>> appendix about a difference between OpenGL and Vulkan with regards to how primitives derived from offsets are handled (internal issue 355). * Add the +<<VK_KHR_get_physical_device_properties2>>+, +<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+ extensions (internal issue 448). * Add the +<<VK_EXT_shader_subgroup_vote>>+ and +<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449). * Update the texture level-of-detail equation in the <<textures-scale-factor,Scale Factor Operation>> section to better approximate the ellipse major and minor axes (internal issue 547). * Forbid non-explicitly allowed uses of interface decorations in the introduction to the <<interfaces,Shader Interfaces>> chapter (internal issue 607). * Replace use of MathJax with KaTeX, for improved load-time performance as well as avoiding the scrolling-and-scrolling behavior due to MathJax asynchronous rendering when loading at an anchor inside the spec. This change also requires moving to HTML5 output for the spec instead of XHTML, and there is a visible difference in that the chapter navigation index is now in a scrollable sidebar instead of at the top of the document. We may or may not retain the nav sidebar based on feedback (internal issue 613). * Improve consistency of markup and formatting in extension appendices (internal issue 631). Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage. If the swapchain has been replaced, then it should not be passed to flink:vkAcquireNextImage. * Add a valid usage statement to flink:vkCreateImageView, that the image must have been created with an appropriate usage bit set. * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section. * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor to account for the multiple viewport feature. If the feature is not enabled, the parameters for these functions have required values that are defined in the <<features-features-multiViewport,multiple viewports>> section of the spec but were not reflected in the valid usage text for these functions. * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common color spaces.

Internal Issues: * Remove redundant descriptions of the etext:VK_USE_PLATFORM_* macros from the <<wsi,Window System Integration>> chapter in favor of the description in the <<boilerplate-wsi-header,Window System-Specific Header Control>> appendix (internal issue 6). * Replace misleading 'can: be destroyed when not X' with more correct 'must: not be destroyed while X' in the <<fundamentals-objectmodel-lifetime,Object Lifetime>> section. Disallow destroying a pipeline layout while a command buffer using it is recording (internal issue 241). * Clarify that ename:VK_IMAGE_USAGE_TRANSIENT_ATTACHMENT_BIT is valid for all images used as attachments in elink:VkImageUsageFlagBits and the slink:VkImageLayout validity language (internal issue 320). * Note that <<extended-functionality-layers,Layers>> may wrap object handles, but that this is a generally discouraged. A link to additional information in the documentation for layer authors is provided (issue 398) * Replace the mustnot: and shouldnot: macros with equivalent must: not and should: not to get rid of non-English words while still highlighting normative language (internal issue 407). * Disallow creating multisampled images with ename:VK_IMAGE_CREATE_CUBE_COMPATIBLE_BIT in the slink:VkImageLayout validity language and the <<features-supported-sample-counts,Supported Sample Counts>> section (internal issue 445). * Fix typo so that flink:vkCmdDrawIndexedIndirect is defined in terms of flink:vkCmdDrawIndexed rather than flink:vkCmdDrawIndirect (internal issue 446). * Reorganize the per-extension information sections to all be in the <<extensions,Layers & Extensions>> appendix. Also fix a typo in +VK_IMG_filter_cubic+ which incorrectly identified it as a +KHR+ extension (internal issue 461). Other Issues: * Use asciidoc markup instead of latexmath to simplify diagrams in the <<features-formats-non-packed,byte mapping tables>> for color formats. * Fix a markup problem with the wildcarded enumerant names in a NOTE in the <<textures-texel-replacement,Texel Replacement>> section. * Fix missing attributes in the XML interface for elink:VkExternalMemoryHandleTypeFlagBitsNV and elink:VkExternalMemoryFeatureFlagBitsNV (KhronosGroup/Vulkan-Hpp issue #25) * Cleanup reference page builds so only core pages are built for releases.

Github Issues: * Refine swapchain association with surface for slink:VkSwapchainKHR, with matching valid usage statements for slink:VkSwapchainCreateInfoKHR and discussion following the <<swapchain-wsi-image-create-info>> table (public issue 637). * Re-remove several valid usage statements from slink:VkImageCreateInfo that had previously been removed at the time that ename:VK_IMAGE_CREATE_EXTENDED_USAGE_BIT was introduced. These statements had incorrectly been restored due to an glitch while merging from the old `1.0` branch to the current `master` branch (public issue 683). Internal Issues: * Fix reference page generation and configure build to generate reference pages 1.1 with all extensions, rather than core only, as was the case for the 1.0 ref pages (internal issues 484, 1056, 1205). * Require that slink:VkMemoryDedicatedRequirements::pname:prefersDedicateAllocation is ename:VK_TRUE when slink:VkMemoryDedicatedRequirements::pname:requiresDedicateAllocation is ename:VK_TRUE (internal issue 1222). * Fix Ruby extension code so `diff_html` Makefile target works (internal issue 1230). * Update `genRelease` script to generate 1.1 + all extensions reference pages - but not the single-page HTML / PDF versions, which are even larger than the API spec (internal issue 1245). Other Issues: * Add missing attributes to `vk.xml` for `VK_ANDROID_native_buffer`. * Specify that the slink:VkAttachmentDescription::pname:format member is the format of the image *view* that will be used for the attachment. * Use core sname:VkPhysicalDeviceFeatures2 in the `structextends` `vk.xml` attribute for sname:VkPhysicalDeviceDescriptorIndexingFeaturesEXT and sname:VkPhysicalDeviceDescriptorIndexingPropertiesEXT, rather than the KHR equivalent it was promoted from. * Fix the "`Fragment Input Attachment Interface`" glossary entry to match the specification body. * Clarify the interaction of sRGB images used as storage or texel buffers with <<textures-output-format-conversion, Texel Output Format Conversion>>. * Moved three valid usage statements from slink:VkRenderPassMultiviewCreateInfo up to slink:VkRenderPassCreateInfo, and added a new valid usage statement for slink:VkRenderPassInputAttachmentAspectCreateInfo. * Added valid usage statements for slink:VkBufferMemoryBarrier and slink:VkImageMemoryBarrier reflecting the global requirement that "`non-sparse resources must be bound to memory before being recorded to command`". New Extensions:

Change log for September 5, 2017 Vulkan 1.0.60 spec update: * Bump API patch number and header version number to 60 for this update. Github Issues: * Document that <<queries-timestamps, Timestamp Queries>> can only be meaningfully compared when they are written from the same queue (public issue 216). * Document that the `<extension>` tag `type` attribute is required for non-disabled extensions (derived from, but does not close public issue 354). * Clean up registry schema length attribute descriptions to be consistent and correct (public issue 555). Internal Issues: * Replace as much of the hand-written extension appendix metadata as possible with asciidoc includes generated from corresponding attributes of +vk.xml+, and enhance the style guide to match. This avoids inconsistencies between +vk.xml+ and the appendices, and produces a more uniform style (internal issue 137). * Remove the generated extDependency.{py,sh} files from the tree and create them dynamically on demand instead, reducing merge conflicts (internal issue 713). * Add a prototype tool for generating in-place difference markup for sections guarded by asciidoc conditionals, and new syntax for open blocks to support it (internal issue 833). * Remove unnecessary restriction of etext:*SYNC_FD_BIT_KHR external handle types to the same physical device in the slink:VkPhysicalDeviceIDPropertiesKHR, flink:VkImportMemoryWin32HandleInfoKHR, slink:VkImportFenceWin32HandleInfoKHR, slink:VkImportFenceFdInfoKHR, slink:VkImportSemaphoreWin32HandleInfoKHR, slink:VkImportSemaphoreFdInfoKHR <<external-memory-handle-types-compatibility, External memory handle types compatibility>>, <<external-semaphore-handle-types-compatibility, External semaphore handle types compatibility>>, and <<external-fence-handle-types-compatibility, External fence handle types compatibility>> sections (internal issue 956). Other Issues: * Remove dependency of +VK_KHX_device_group+ on +VK_KHR_swapchain+ (there is an interaction, but not a strict dependency), and add a new `extension` attribute to the `<require` XML tag to allow classifying a subset of interfaces of an extension as requiring another extension.

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for January 23, 2017 Vulkan 1.0.39 spec update: * Bump API patch number and header version number to 39 for this update. Github Issues: * Clarified that only accesses via the specified buffer/image subresource ranges are included in the access scopes (public issue 306). * Add missing valid usage statements for flink:vkCreateComputePipelines and flink:vkCreateGraphicsPipelines (public issue 427). Internal Issues: * Add a Note to the <<invariance,Invariance>> appendix about a difference between OpenGL and Vulkan with regards to how primitives derived from offsets are handled (internal issue 355). * Add the +<<VK_KHR_get_physical_device_properties2>>+, +<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+ extensions (internal issue 448). * Add the +<<VK_EXT_shader_subgroup_vote>>+ and +<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449). * Update the texture level-of-detail equation in the <<textures-scale-factor,Scale Factor Operation>> section to better approximate the ellipse major and minor axes (internal issue 547). * Forbid non-explicitly allowed uses of interface decorations in the introduction to the <<interfaces,Shader Interfaces>> chapter (internal issue 607). * Replace use of MathJax with KaTeX, for improved load-time performance as well as avoiding the scrolling-and-scrolling behavior due to MathJax asynchronous rendering when loading at an anchor inside the spec. This change also requires moving to HTML5 output for the spec instead of XHTML, and there is a visible difference in that the chapter navigation index is now in a scrollable sidebar instead of at the top of the document. We may or may not retain the nav sidebar based on feedback (internal issue 613). * Improve consistency of markup and formatting in extension appendices (internal issue 631). Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage. If the swapchain has been replaced, then it should not be passed to flink:vkAcquireNextImage. * Add a valid usage statement to flink:vkCreateImageView, that the image must have been created with an appropriate usage bit set. * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section. * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor to account for the multiple viewport feature. If the feature is not enabled, the parameters for these functions have required values that are defined in the <<features-features-multiViewport,multiple viewports>> section of the spec but were not reflected in the valid usage text for these functions. * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common color spaces.

Change log for November 25, 2016 Vulkan 1.0.35 spec update: * Bump API patch number and header version number to 35 for this update. Github Issues: * Document in the <<memory-device-hostaccess,Host Access>> section that mapping and unmapping does not invalidate or flush the mapped memory (public issues 27, 126). * Redefine the entire <<synchronization>> chapter in terms of consistent and well defined terminology, that's called out at the start of the chapter. This terminology is applied equally to all synchronization types, including subpass dependencies, submissions, and much of the implicit ordering stuff dotted around the spec. Key terms are laid out in the <<synchronization-dependencies,Execution and Memory Dependencies>> section at the top of the rewritten chapter (public issues 128, 131, 132, 217, 299, 300, 302, 306, 322, 346, 347, 371, 407). * Specify order of submission for batches in the <<vkQueueSubmit,vkQueueSubmit>> and <<vkQueueBindSparse,vkQueueBindSparse>> commands (public issue 371). * Add valid usage statements to each of the WSI extension sections indicating that the WSI-specific structure parameters must be valid, and remove automatically generated valid usage statements now covered by the manual sections (public issue 383). * Clarify render pass compatibility for flink:vkCmdExecuteCommands (public issue 390). Internal Issues: * Update +vk.xml+ to make previously explicit valid usage statements for <<vkDebugReportMessageEXT,vkDebugReportMessageEXT>> implicit instead (internal issue 553). * Add valid usage statement for slink:VkCreateImageInfo preventing creation of 1D sparse images (internal issue 573). * Fix Python scripts to always read/write files in utf-8 encoding, and a logic error in reflib.py which could cause a fatal error for malstructured asciidoc (internal issues 578, 586).

Change log for March 10, 2016 Vulkan 1.0.6 spec update: * Bump API patch number and header version number to 6 for this update. Github Issues: * Define 'invocation group' for compute and graphics shaders. Cleanup definition and use of 'workgroup', and add glossary entries (public issue 1). * Various minor editorial fixes (public issue 33). * Clarify locations for block members in the &lt;&lt;interfaces-iointerfaces-locations,Location Assignment>> section (public issue 45). * Editorial fixes for &lt;&lt;commandbuffer-allocation,Command Buffer Allocation>> section (public issues 54, 59). * Clarify behavior of depth test in the &lt;&lt;fragops-depth,Depth Test&gt;&gt; section (public issues 80, 81). * Remove discussion of return codes from flink:vkGetPhysicalDeviceSparseImageFormatProperties and flink:vkGetImageSparseMemoryRequirements, which don't return values (public issue 82). * Allow flink:vkCmdDrawIndirect and flink:vkCmdDrawIndexedIndirect pname:drawCount of 0, as well as 1, when the multiDrawIndirect feature is not supported (public issue 88). * Remove confusing wording in the &lt;&lt;features-limits,Limits>> section describing the slink:VkPhysicalDeviceLimits pname:minTexelBufferOffsetAlignment, pname:minUniformBufferOffsetAlignment, and pname:minStorageBufferOffsetAlignment members as both minimums and maximums (public issue 91). * Clarified that only the RGB components should be affected in places where sRGB is referred to in the spec, such as ASTC formats. Minor re-wording to avoid "color space" when actively incorrect, now that we refer to the Data Format Spec which actually makes a distinction between color space and transfer function (public issue 94). * Treat pname:pPropertyCount == 0 consistently in flink:vkEnumerateInstanceLayerProperties and flink:vkEnumerateDeviceLayerProperties (public issue 99) * Cleanup minor editorial issues in chapters 14-17 (public issue 100). * Clarify definition of flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties (public issue 101). * Define the flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties pname:pLayerName parameter to be a pointer to a null-terminated UTF-8 string (public issue 101). * Rearrange "Missing information" references in mandatory format tables (public issue 101). * Clarify that the enumerated extensions returned by flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties will only include extensions provided by the platform or extensions implemented in implicitly enabled layers (public issue 101). * Miscellaneous editorial fixes. Include the Vulkan spec patch number in the PDF title. Fix label on &lt;&lt;fig-non-strict-lines,Non strict lines>> diagram. Use more easily distinguished symbols in tables in the &lt;&lt;features-required-format-support,Required Format Support>> section. Don't require FQDNs used as layer names be encoded in lower case if not possible, in the &lt;&lt;extensions-naming-conventions, Extension and Layer Naming Conventions>> section (public issues 101, 119, 121). Internal Issues: * Fixed excessive spacing in tables in XHTML (internal issue 18). * Clarify that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT applies to secondary command buffers. Previously spec only referred to the members of pname:pCommandBuffers being affected by this bit. Added a separate slink:VkSubmitInfo Valid Usage restriction specifying that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT also applies to any secondary command buffers that are recorded into the primary command buffers in pname:pCommandBuffers (internal issue 106). * Clarify that slink:VkDeviceCreateInfo::pname:pEnabledFeatures can be NULL (internal issue 117). * Remove "the value of" where it is redundant (e.g. speaking of an API parameter, struct member, or SPIR-V variable, but not when speaking of color components) (internal issue 175). * Forced patch version to always be 0 in the header. Add a "VK_API_VERSION_<major>_<minor>" macro for people to use to do the right thing. Add a VK_HEADER_VERSION which captures the header release number independent of the spec patch number (internal issue 176). * Correct description of slink:VkPipelineShaderStageCreateInfo::pname:pName to "a pointer to a null-terminated UTF-8 string" (internal issue #197). Other Commits: * Updated DataFormat spec reference to the new date for revision 5 of that spec. * Fixed KEEP option (to retain LaTeX intermediate files) in the Makefile to be included when edited there, as well as set on the command line. * Reserve and add "VK_IMG_filter_cubic" to the registry, and implement script functionality to add and remove validity from existing functions. Includes schema and readme changes. * Update GL_KHR_vulkan_glsl so push_constants do not have descriptor sets.

Internal Issues: * Document that the requested patch version number specified as part of slink:VkApplicationInfo::pname:apiVersion is ignored when creating an instance (internal issue 176). * Clarify handling of extension structs in the <<fundamentals-validusageValid Usage>> section (internal issue 254). * Update required slink:VkImageFormatProperties::pname:maxMipLevels to be limited to the maximum allowed mipmap pyramid size corresponding to the actual maximum supported size for the format (internal issue 256). * Modify the <<features-extentperimagetype,Allowed Extent Values Based On Image Type>> section so the allowed maximum extent is the maximum image dimension supported for each dimension of the type of texture being queried (internal issue 257). * Clarify in the <<spirvenv-module-validation,Validation Rules within a Module>> section that at least one of the code:LocalSize execution mode or code:WorkgroupSize decoration is required for each compute shader entry point in a shader module (internal issue 279). * Add validity rules for formats in flink:vkCmdClearColorImage and flink:vkCmdClearDepthStencilImage (internal issue 283). * Clarify that slink:VkImageFormatProperties::pname:maxResourceSize is an upper bound, and that it may not be possible to create an image anywhere near that size (internal issue 284). Other Commits: * Fix various minor markup errors reported by validation scripts. * Change copyright from Khronos Free Use License to Apache 2.0 license on relevant script/XML/header files. This does not affect the specification source copyright.

Change log for November 25, 2016 Vulkan 1.0.35 spec update: * Bump API patch number and header version number to 35 for this update. Github Issues: * Document in the <<memory-device-hostaccess,Host Access>> section that mapping and unmapping does not invalidate or flush the mapped memory (public issues 27, 126). * Redefine the entire <<synchronization>> chapter in terms of consistent and well defined terminology, that's called out at the start of the chapter. This terminology is applied equally to all synchronization types, including subpass dependencies, submissions, and much of the implicit ordering stuff dotted around the spec. Key terms are laid out in the <<synchronization-dependencies,Execution and Memory Dependencies>> section at the top of the rewritten chapter (public issues 128, 131, 132, 217, 299, 300, 302, 306, 322, 346, 347, 371, 407). * Specify order of submission for batches in the <<vkQueueSubmit,vkQueueSubmit>> and <<vkQueueBindSparse,vkQueueBindSparse>> commands (public issue 371). * Add valid usage statements to each of the WSI extension sections indicating that the WSI-specific structure parameters must be valid, and remove automatically generated valid usage statements now covered by the manual sections (public issue 383). * Clarify render pass compatibility for flink:vkCmdExecuteCommands (public issue 390). Internal Issues: * Update +vk.xml+ to make previously explicit valid usage statements for <<vkDebugReportMessageEXT,vkDebugReportMessageEXT>> implicit instead (internal issue 553). * Add valid usage statement for slink:VkCreateImageInfo preventing creation of 1D sparse images (internal issue 573). * Fix Python scripts to always read/write files in utf-8 encoding, and a logic error in reflib.py which could cause a fatal error for malstructured asciidoc (internal issues 578, 586).

Change log for October 13, 2018 Vulkan 1.1.88 spec update: * Update release number to 88. Public Issues: * Make clear that tname:PFN_vkDebugUtilsMessengerCallbackEXT::pname:messageTypes is a bitmask, and correct a typo in the spelling of slink:VkDebugUtilsMessengerCreateInfoEXT.txt::pname:messageType (public pull request 800). * Make an ABI-compatible change of the type of slink:VkPhysicalDeviceDriverPropertiesKHR::pname:driverID to use the new elink:VkDriverIdKHR type (public issue 811). Internal Issues: * Clarify for the <<features-features-shaderStorageImageExtendedFormats>> feature and in the <<spirvenv-capabilities-table>> that the feature means that all of the formats are supported, and that otherwise the features can be queried per-format (internal issue 1273). * Clarified interactions of `VK_EXT_external_memory_host` with host cache management commands and structures flink:vkMapMemory, flink:vkFlushMappedMemoryRanges, slink:VkMappedMemoryRange, and flink:vkUnmapMemory using the new glossary term "`Host Mapped Device Memory`" (internal issue 1385). * Update the language for flink:vkCreateViSurfaceNN.txt describing the pname:currentExtent of a VI surface to more accurately reflect current capabilities, replacing "`undefined`" with more explicit behavior (internal issue 1410). New Extensions: * `VK_EXT_calibrated_timestamps` * `VK_EXT_image_drm_format_modifier` (this extension was previously disabled in vk.xml, and has now been enabled after some changes to fix performance issues). * `VK_EXT_pci_bus_info` * `VK_EXT_transform_feedback` * `VK_GOOGLE_hlsl_functionality1`, exposing support for `SPV_GOOGLE_hlsl_functionality1`. * `VK_GOOGLE_decorate_string`, exposing support for `SPV_GOOGLE_decorate_string`.

Change log for November 27, 2017 Vulkan 1.0.66 spec update: * Bump API patch number and header version number to 66 for this update. Github Issues: * Clarified how and when ename:VK_ERROR_TOO_MANY_OBJECTS is generated in flink:vkAllocate Memory, and remove incorrect valid usage statement about exceeding the API limit (public issue 356). * Minor clarification of the description of flink:vkUpdateDescriptorSetWithTemplateKHR::pname:descriptorUpdateTemplate (public issue 564). * Minor fixes for flink:vkCmdSetViewportWScalingNV (public pull request 588). * Fix random name markup issues (public pull request 603). * Fix code:BuiltIn decoration typo in the <<fxvertex-attrib, Vertex Attributes>> section (public pull request 606). * Fix synchronization language following the definition of flink:vkAcquireNextImageKHR (public issue 607). * Restore descriptions of several commands and structures missing from the generated spec due to a mistyped asciidoctor conditional (public issue 612). * Fix 1.0.41 changelog to refer to public issues 403/404 (public issue 618). Internal Issues: * Refactor valid usage statements with internal conditionals in `copies.txt`, `pipelines.txt`, `renderpass.txt`, and `resources.txt` so each branch of the conditional appears as a standalone statement which can contain a separate VUID. This should have no impact on the generated specs, but is necessary given the present state of the VU extractor and the validation layer code that consumes them (internal issue 1043). * Fix VkQueueGlobalPriorityEXT enum values missing _EXT suffix (internal issue 1045). * Clarified initial ownership of resources bound to shared memory objects, (internal issue 1068). * Fix duplicated valid usage ID tag for flink:vkCmdCopyImage, and make the required layouts include ename:VK_IMAGE_LAYOUT_TRANSFER_SRC_OPTIONAL in both cases (internal issue 1084). Other Issues: * Remove the noise functions from GLSL for SPIR-V for Vulkan in the `GL_KHR_vulkan_glsl.txt` extension. New Extensions: * `VK_EXT_external_memory_host` * `VK_EXT_external_memory_dma_buf` * `VK_EXT_queue_family_foreign`

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for February 10, 2017 Vulkan 1.0.40 spec update: * Bump API patch number and header version number to 40 for this update. * There is a major build change in this release. We are now using the Ruby-based ``asciidoctor'' implementation, rather than the Python-based ``asciidoc'' implementation, to process the specification. While the actual specification markup changes were minimal, this requires a new set of build tools and a very different installation process, especially because we now use an experimental direct-to-PDF backend for Asciidoctor instead of Docbook->dblatex->PDF. It is no longer possible to build the Specification using asciidoc. See doc/specs/vulkan/README.adoc for some guidance on installing the new toolchain components. * There are some minor rendering issues in the PDF output due to teething problems with the asciidoctor toolchain, especially with mathematical equations. We are aware of these and working on them. Github Issues: * Updated sample code for the <<sparsememory-examples-basic,sparse resource binding example>> (public issue 97). * Modify line and point clipping behavior in the <<vertexpostproc-clipping, Primitive Clipping>> section to allow for pop-free behavior. The ability to check for which behavior is implemented may be added a future feature or extension (public issue 113). * Unify the discussions of implicit ordering throughout the spec, in particular in the new sections <<drawing-primitive-order, Primitive Order>>, <<primrast-order, Rasterization Order>>, and <<synchronization-implicit, Implicit Synchronization Guarantees>>; the discussion of <<synchronization-submission-order, submission order>>; and references elsewhere to these sections (public issue 133). * Clarify \<\<descriptorsets-compatibility,Pipeline Layout Compatibility>> language and introduce the term ``identically defined'' (public issue 164). * Add a dependency to the +VK_EXT_debug_marker+ extension that's needed to reuse the object type enum from +VK_EXT_debug_report+, and moves the definition of that enum into +VK_EXT_debug_report+ where it should be (public issue 409). * Remove redundant valid usage statement from slink:VkImageBlit (public issue 421). * Update GL_KHR_vulkan_glsl to allow the ternary operator to result in a specialization constant (public issue 424). * Fix valid usage for flink:VkPipelineShaderStageCreateInfo (public issue 426). * Correct typo in New Objects list for <<VK_EXT_debug_report>> (public issue 447). Internal Issues: * Moved to asciidoctor for spec builds (internal issue 121). * Update style guide to describe where to put new extensions-specific asciidoc files, and what to name them (internal issue 626). * Add src/spec/indexExt.py to autogenerate registry index entries linking into the 1.0-extensions specification, instead of maintaining the index manually. (internal issue 642). * Autogenerate extension dependencies and lists of all extensions and all KHR extensions from the "supported" attributes in +vk.xml+. Execute +make config/extDependency.sh+ from +doc/specs/vulkan+ when a supported extension is added to vk.xml, to regenerate the dependency script. The consequence is that specifying a single extension to the +makeExt+ script will automatically enable all extensions it depends on as well, and that the +makeAllExts+ and +makeKHR+ scripts do not need to be updated when a new extension is supported (internal issue 648). * Put extension appendices all at the same asciidoc section level, so KHR WSI extensions show up in the HTML index (internal issue 648). Other Issues: * Imbed images in the generated HTML specs instead of loading them from the images/ directory. * Fix missing EXT in extension name (ename:VK_EXT_SWAPCHAIN_COLOR_SPACE_EXTENSION_NAME). * Add new +VK_EXT_SMPTE_2086_metadata+ extension. * In the <<platformCreateSurface_xlib,Xlib Surface>> section of the +VK_KHR_xlib_surface+ specification, add language warning users that they always need to call code:XinitThreads. * Use the term "presentable image" (rather than "swapchain image") consistently in +VK_KHR_swapchain+ and related extensions, and add a glossary term defining it. * Relocate the valid usage for samples of flink:vkGetPhysicalDeviceSparseImageFormatProperties2KHR::pname:pFormatInfo to be below the flink:VkPhysicalDeviceSparseImageFormatInfo2KHR structure.

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for January 23, 2017 Vulkan 1.0.39 spec update: * Bump API patch number and header version number to 39 for this update. Github Issues: * Clarified that only accesses via the specified buffer/image subresource ranges are included in the access scopes (public issue 306). * Add missing valid usage statements for flink:vkCreateComputePipelines and flink:vkCreateGraphicsPipelines (public issue 427). Internal Issues: * Add a Note to the <<invariance,Invariance>> appendix about a difference between OpenGL and Vulkan with regards to how primitives derived from offsets are handled (internal issue 355). * Add the +<<VK_KHR_get_physical_device_properties2>>+, +<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+ extensions (internal issue 448). * Add the +<<VK_EXT_shader_subgroup_vote>>+ and +<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449). * Update the texture level-of-detail equation in the <<textures-scale-factor,Scale Factor Operation>> section to better approximate the ellipse major and minor axes (internal issue 547). * Forbid non-explicitly allowed uses of interface decorations in the introduction to the <<interfaces,Shader Interfaces>> chapter (internal issue 607). * Replace use of MathJax with KaTeX, for improved load-time performance as well as avoiding the scrolling-and-scrolling behavior due to MathJax asynchronous rendering when loading at an anchor inside the spec. This change also requires moving to HTML5 output for the spec instead of XHTML, and there is a visible difference in that the chapter navigation index is now in a scrollable sidebar instead of at the top of the document. We may or may not retain the nav sidebar based on feedback (internal issue 613). * Improve consistency of markup and formatting in extension appendices (internal issue 631). Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage. If the swapchain has been replaced, then it should not be passed to flink:vkAcquireNextImage. * Add a valid usage statement to flink:vkCreateImageView, that the image must have been created with an appropriate usage bit set. * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section. * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor to account for the multiple viewport feature. If the feature is not enabled, the parameters for these functions have required values that are defined in the <<features-features-multiViewport,multiple viewports>> section of the spec but were not reflected in the valid usage text for these functions. * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common color spaces.

Change log for April 15, 2016 Vulkan 1.0.10 spec update: * Bump API patch number and header version number to 10 for this update. Github Issues: * Slightly tweak the <<memory-allocation,Host Memory>> allocator language so that an application wrapping the standard C alloc/free/realloc functions is still correct - the previous language was too strong with regards to freeing memory. Also made certain scenarios clearer - an implementation may now continue without error if an allocation failed and it is able to continue correctly (public issue 21). * Require that etext:VK_*_CREATE_SPARSE_BINDING_BIT is set when the corresponding etext:VK_*_CREATE_SPARSE_RESIDENCY_BIT is used, in the <<sparsememory-miptail,Mip Tail Regions>> section and related commands flink:vkCreateBuffer and flink:vkCreateImage (public issue 84). * Update the <<features,Features, Limits, and Formats>> chapter to clarify interactions between optional features and dynamic state for the pname:depthBiasClamp and pname:wideLines features (public issue 89). * Describe the code:WorkgroupSize builtin in the <<interfaces-builtin-variables,Built-In Variables>> section, and update the <<compute-shaders,Compute Shaders>> section to further clarify how to set the number of workgroups to execute in a compute shader (public issue 145). * Use the term *image subresource* everywhere instead of *subresource*, except for the special case of *host-accessible subresource*, which may be either an image subresource or buffer range (public issue 120) * Add a note to the <<features,Features, Limits, and Formats>> section about extensibility of structures (Public issue 165). * Fix return code flink:vkAcquireNextImageKHR when the timeout parameter is 0 to ename:VK_NOT_READY instead of ename:VK_TIMEOUT (public issue 170). * Fix typo in slink:VkLayerProperties::pname:apiVersion field (public issue 172). Internal Issues: * Fix a few minor internally-detected typos. * Minor formatting tweaks to pseudocode in the <<resources,Resource Creation>> chapter (internal issue 179). * Fix typo in the definition of point sampling for elink:VkCullModeFlagBits (internal issue 268).

Github Issues: * Fix type mismatch in swapchain image equivalency table (public issue 289). * Fix a copy-and-paste error in the description of flink:vkGetSwapchainImagesKHR::pname:pSwapchainImages, that said it was an array of ``sname:VkSwapchainImageKHR structures'' instead of an array of ``sname:VkImage handles'' (public issue 292). * Specify that ename:VK_IMAGE_CREATE_CUBE_COMPATIBLE_BIT is only valid for ename:VK_IMAGE_TYPE_2D images (public issue 293). * Add a valid usage statement to flink:vkCmdExecuteCommands saying that when called outside a render pass instance, the secondary command buffers must not have been created with the ename:VK_COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT (public issue 297). * Fix description of +VK_NO_STDINT_H+ in the <<boilerplate-platform-macros,platform macros>> section (public issue 314). Internal Issues: * Normalize the language for the remaining built-in variables in the <<interfaces-builtin-variables,Built-In Variables>> section. Fix code:FrontFacing and code:HelperInvocation, as they should be of code:boolean type rather than code:integer (internal issue 323). * Clarify that when ename:VK_WHOLE_SIZE is used for a buffer descriptor range, the effective range must still be within the max buffer range (internal issue 426). * Clarify that command buffers and descriptor sets are allocated rather than created. Also clarify when the recording state of a command buffer is relevant (internal issue 434).

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Github Issues: * Provide alternate length attributes (altlen=) in the XML schema, for those using length attributes to generate code instead of documentation (public issue 555). * Fix erroneous references to `latex:` being used for asciidoc math markup, rather than `latexmath:` (public pull request 556). * Add author ID to XML for Kazan software renderer (public pull request 557). Internal Issues: * Add the <<fundamentals-abi,Application Binary Interface>> section describing platform ABI requirements and recommendations, add examples of function and function pointer declarations to the <<boilerplate-platform-specific-calling-conventions, Platform-Specific Calling Conventions>> section, and remove related language that existed elsewhere in the specification (internal issue 64). * Describe where to document valid usage interactions of chained structures in the style guide, and fix one case now appearing in slink:VkBufferCreateInfo instead of the child slink:VkDedicatedAllocationBufferCreateInfoNV structure (internal issue 715). * Add example to the style guide of describing enumerated types which are empty when the spec is built without relevant extensions enabled, and apply it to existing examples for elink:VkDescriptorSetLayoutCreateFlagBits and elink:VkSubpassDescriptionFlagBits (internal issue 864). * Add a note to the <<fundamentals-validusage-enums, Valid Usage for Enumerated Types>> section that the special values suffixed with etext:_BEGIN_RANGE, etext:_END_RANGE, etext:_RANGE_SIZE and etext:_MAX_ENUM are not part of the API and should: not be used by applications (internal issue 872). * Added note to flink:vkCmdUpdateBuffers explaining the performance penalty for copies done in this way, and why the upper copy limit is what it is (internal issue 952). * Update `VK_KHX_device_group` to split some functionality into the new `VK_KHR_bind_memory2` extension, and rename that functionality (internal issue 969). * Remove *Status* fields from extension appendices, since they are by definition published and complete by the time they reach the public github repository (internal issue 973). Other Issues: * Update Data Format specification dependency to version 1.2 and change references to DF sections accordingly. * Update XML to make the pname:pAllocator parameter of flink:vkRegisterDeviceEventEXT and flink:vkRegisterDisplayEventEXT in the `VK_EXT_display_control` extension as optional. New Extensions: * `VK_KHR_bind_memory2` * `VK_KHR_image_format_list` * `VK_KHR_maintenance2` * `VK_KHR_sampler_ycbcr_conversion`

Implicit chroma reconstruction::
An implementation of sampler Y'C~B~C~R~ conversion which reconstructs
the reduced-resolution chroma samples directly at the sample point, as
part of the normal texture sampling operation.
This is distinct from an _explicit chroma reconstruction_
implementation, which reconstructs the reduced-resolution chroma samples
to the resolution of the luma samples, then filters the result as part
of texture sample interpolation.

There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Internal Issues: * Add the <<fundamentals-abi,Application Binary Interface>> section describing platform ABI requirements and recommendations, add examples of function and function pointer declarations to the <<boilerplate-platform-specific-calling-conventions, Platform-Specific Calling Conventions>> section, and remove related language that existed elsewhere in the specification (internal issue 64). * Describe where to document valid usage interactions of chained structures in the style guide, and fix one case now appearing in slink:VkBufferCreateInfo instead of the child slink:VkDedicatedAllocationBufferCreateInfoNV structure (internal issue 715). * Add example to the style guide of describing enumerated types which are empty when the spec is built without relevant extensions enabled, and apply it to existing examples for elink:VkDescriptorSetLayoutCreateFlagBits and elink:VkSubpassDescriptionFlagBits (internal issue 864). * Add a note to the <<fundamentals-validusage-enums, Valid Usage for Enumerated Types>> section that the special values suffixed with etext:_BEGIN_RANGE, etext:_END_RANGE, etext:_RANGE_SIZE and etext:_MAX_ENUM are not part of the API and should: not be used by applications (internal issue 872). * Added note to flink:vkCmdUpdateBuffers explaining the performance penalty for copies done in this way, and why the upper copy limit is what it is (internal issue 952). * Update `VK_KHX_device_group` to split some functionality into the new `VK_KHR_bind_memory2` extension, and rename that functionality (internal issue 969). * Remove *Status* fields from extension appendices, since they are by definition published and complete by the time they reach the public github repository (internal issue 973). Other Issues: * Update Data Format specification dependency to version 1.2 and change references to DF sections accordingly. * Update XML to make the pname:pAllocator parameter of flink:vkRegisterDeviceEventEXT and flink:vkRegisterDisplayEventEXT in the `VK_EXT_display_control` extension as optional. New Extensions: * `VK_KHR_bind_memory2` * `VK_KHR_image_format_list` * `VK_KHR_maintenance2` * `VK_KHR_sampler_ycbcr_conversion`

Internal Issues: * Remove duplicate language from the description of the pname:fence parameter to flink:vkQueueSubmit and improve validity language (internal issue 91). * Added documentation for "optional" attribute to XML readme.tex/pdf (internal issue 149). * Clarify the host-side data validity rules and behavior of flink:vkFlushMappedMemoryRanges and flink:vkInvalidateMappedMemoryRanges (internal issue 266). Other Commits: * Added clarification to flink:vkCmdFillBuffer regarding the use of ename:VK_WHOLE_SIZE. * Fixed and documented implementation of "validextensionstructs" attribute. in XML processing scripts and readme.tex/pdf. * Add missing validity statements to flink:vkResetEvent and flink:vkCmdResetEvent. * Fix validity for the ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT flag. Correct all the draw/dispatch commands to mention optimally tiled images as well as linear tiled images, and say image VIEWS instead of images. Add validity statement to flink:vkCmdBlitImage * Replace the {apiname} macro with hardcoded "Vulkan", now that we've committed to that name. * Add the VK_AMD_rasterization_order extension to vk.xml.

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage. If the swapchain has been replaced, then it should not be passed to flink:vkAcquireNextImage. * Add a valid usage statement to flink:vkCreateImageView, that the image must have been created with an appropriate usage bit set. * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section. * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor to account for the multiple viewport feature. If the feature is not enabled, the parameters for these functions have required values that are defined in the <<features-features-multiViewport,multiple viewports>> section of the spec but were not reflected in the valid usage text for these functions. * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common color spaces.

Change log for November 25, 2016 Vulkan 1.0.35 spec update: * Bump API patch number and header version number to 35 for this update. Github Issues: * Document in the <<memory-device-hostaccess,Host Access>> section that mapping and unmapping does not invalidate or flush the mapped memory (public issues 27, 126). * Redefine the entire <<synchronization>> chapter in terms of consistent and well defined terminology, that's called out at the start of the chapter. This terminology is applied equally to all synchronization types, including subpass dependencies, submissions, and much of the implicit ordering stuff dotted around the spec. Key terms are laid out in the <<synchronization-dependencies,Execution and Memory Dependencies>> section at the top of the rewritten chapter (public issues 128, 131, 132, 217, 299, 300, 302, 306, 322, 346, 347, 371, 407). * Specify order of submission for batches in the <<vkQueueSubmit,vkQueueSubmit>> and <<vkQueueBindSparse,vkQueueBindSparse>> commands (public issue 371). * Add valid usage statements to each of the WSI extension sections indicating that the WSI-specific structure parameters must be valid, and remove automatically generated valid usage statements now covered by the manual sections (public issue 383). * Clarify render pass compatibility for flink:vkCmdExecuteCommands (public issue 390). Internal Issues: * Update +vk.xml+ to make previously explicit valid usage statements for <<vkDebugReportMessageEXT,vkDebugReportMessageEXT>> implicit instead (internal issue 553). * Add valid usage statement for slink:VkCreateImageInfo preventing creation of 1D sparse images (internal issue 573). * Fix Python scripts to always read/write files in utf-8 encoding, and a logic error in reflib.py which could cause a fatal error for malstructured asciidoc (internal issues 578, 586).

Change log for December 1, 2016 Vulkan 1.0.36 spec update: * Bump API patch number and header version number to 36 for this update. Github Issues: * Fix "recorded with" terminology in the valid usage language for the flink:vkCmdExecuteCommands::pname:pCommandBuffers parameter (public issue 390). * Modify +genvk.py+ to support specifying extensions to remove from output generators, allowing the extension loader +vulkan_ext.c+ to be created without WSI extensions which are statically exported by the Vulkan loader (public issue 412). * Added validation language for slink:VkSubpassDependency and in the <<synchronization-access-types-supported,supported access types>> section to catch access masks that include bits which are not supported by pipeline stages in the stage masks (partially addresses public issue 1006). Internal Issues: * Added validation language for flink:vkCmdWaitEvents, flink:vkQueueSubmit, flink:VkRenderPassCreateInfo, and in the <<synchronization-pipeline-stages-supported>> section to prevent recording stage dependencies that aren't supported on the queue (internal issue 516). * Make a few changes that generalize spec language for use with possible future extensions by adding glossary terms and generalizing ``feature'' to ``feature or extension'' where relevant (internal issues 448, 590). * Added "pipeline type" attribute to +vk.xml+ for relevant commands and utilize it in automatic generation of the Command Properties table (internal issue 517). * Specify that WSI implementations must provide both UNORM and sRGB formats in the description of slink:VkColorSpaceKHR (internal issue 529). * Remove nesting of explicit valid usage statements where it is not meaningful (internal issue 583). Other Issues: * Add validity language requiring that slink:VkPushConstantRange::pname:offset be a multiple of 4, as stated in the spec language.

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Change log for June 10, 2016 Vulkan 1.0.16 spec update: * Bump API patch number and header version number to 16 for this update. Github Issues: * Clarify that integer border values are meant to be 0/1, and that integer texture lookups are sign-extended in the <<textures-format-conversion,Format Conversion>> and <<textures-texel-replacement,Texel Replacement>> sections (public issue 52). * Add logic to generate spec boilerplate without using the 'git' command-line client, needed when building from a tarball or another source of the Vulkan tree rather than a cloned git repo. Remove boilerplate as part of 'clean' target (public issue 195). * Document that color writes and clears to unused attachments have no effect for slink:VkClearAttachment and elink:VkColorComponentFlagBits (public issue 198). * Fixed flink:vkCmdExecuteCommands validity statement for sname:VkCommandBufferInheritanceInfo::pname:framebuffer. If used, it must match the framebuffer in the current renderpass instance (public issue 226). * Added valid usage language to require for all functions that set dynamic state that the currently bound graphics pipeline has the corresponding dynamic state enabled (public issue 235). Internal Issues: * Clarify for flink:vkEnumerateInstanceExtensionProperties, in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section, and in the <<glossary,Glossary>> section when functionality should be exposed as an instance extension, as a device extension, or as both (internal issue 109). * Place WorkgroupSize in alphabetical order in the <<interfaces-builtin-variables,Built-in Variables>> section (internal issue 323). * Corrects valid usage in vkEndRenderPass to only affect primary render passes, as secondaries may be entirely within a render pass, and should be able to be ended (previous language disallowed that) (internal issue 338). * Fix relational operator from <= to >= in the <<features-extentperimagetype,Allowed Extent Values>> section (internal issue 343). * Disallow recursion under SPIR-V entry points in the <<spirvenv-module-validation,Validation Rules within a Module>> section (internal SPIR-V issue 37). Other Commits: * Use standard Python ElementTree package instead of lxml.etree in header / validation layer / include autogeneration from XML, reducing platform dependencies.

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation.

Instance (Memory)::
In a logical device representing more than one physical device, some
device memory allocations have the requested amount of memory allocated
multiple times, once for each physical device in a device mask.
Each such replicated allocation is an instance of the device memory.
Instance (Resource)::
In a logical device representing more than one physical device, buffer
and image resources exist on all physical devices but can: be bound to
memory differently on each.
Each such replicated resource is an instance of the resource.

The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Minor re-wording to avoid "color space" when actively incorrect, now that we refer to the Data Format Spec which actually makes a distinction between color space and transfer function (public issue 94). * Treat pname:pPropertyCount == 0 consistently in flink:vkEnumerateInstanceLayerProperties and flink:vkEnumerateDeviceLayerProperties (public issue 99) * Cleanup minor editorial issues in chapters 14-17 (public issue 100). * Clarify definition of flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties (public issue 101). * Define the flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties pname:pLayerName parameter to be a pointer to a null-terminated UTF-8 string (public issue 101). * Rearrange "Missing information" references in mandatory format tables (public issue 101). * Clarify that the enumerated extensions returned by flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties will only include extensions provided by the platform or extensions implemented in implicitly enabled layers (public issue 101). * Miscellaneous editorial fixes. Include the Vulkan spec patch number in the PDF title. Fix label on &lt;&lt;fig-non-strict-lines,Non strict lines>> diagram. Use more easily distinguished symbols in tables in the &lt;&lt;features-required-format-support,Required Format Support>> section. Don't require FQDNs used as layer names be encoded in lower case if not possible, in the &lt;&lt;extensions-naming-conventions, Extension and Layer Naming Conventions>> section (public issues 101, 119, 121). Internal Issues: * Fixed excessive spacing in tables in XHTML (internal issue 18). * Clarify that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT applies to secondary command buffers. Previously spec only referred to the members of pname:pCommandBuffers being affected by this bit. Added a separate slink:VkSubmitInfo Valid Usage restriction specifying that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT also applies to any secondary command buffers that are recorded into the primary command buffers in pname:pCommandBuffers (internal issue 106). * Clarify that slink:VkDeviceCreateInfo::pname:pEnabledFeatures can be NULL (internal issue 117). * Remove "the value of" where it is redundant (e.g. speaking of an API parameter, struct member, or SPIR-V variable, but not when speaking of color components) (internal issue 175). * Forced patch version to always be 0 in the header. Add a "VK_API_VERSION_<major>_<minor>" macro for people to use to do the right thing. Add a VK_HEADER_VERSION which captures the header release number independent of the spec patch number (internal issue 176). * Correct description of slink:VkPipelineShaderStageCreateInfo::pname:pName to "a pointer to a null-terminated UTF-8 string" (internal issue #197). Other Commits: * Updated DataFormat spec reference to the new date for revision 5 of that spec. * Fixed KEEP option (to retain LaTeX intermediate files) in the Makefile to be included when edited there, as well as set on the command line. * Reserve and add "VK_IMG_filter_cubic" to the registry, and implement script functionality to add and remove validity from existing functions. Includes schema and readme changes. * Update GL_KHR_vulkan_glsl so push_constants do not have descriptor sets.

Internal Issues: * Fixed excessive spacing in tables in XHTML (internal issue 18). * Clarify that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT applies to secondary command buffers. Previously spec only referred to the members of pname:pCommandBuffers being affected by this bit. Added a separate slink:VkSubmitInfo Valid Usage restriction specifying that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT also applies to any secondary command buffers that are recorded into the primary command buffers in pname:pCommandBuffers (internal issue 106). * Clarify that slink:VkDeviceCreateInfo::pname:pEnabledFeatures can be NULL (internal issue 117). * Remove "the value of" where it is redundant (e.g. speaking of an API parameter, struct member, or SPIR-V variable, but not when speaking of color components) (internal issue 175). * Forced patch version to always be 0 in the header. Add a "VK_API_VERSION_<major>_<minor>" macro for people to use to do the right thing. Add a VK_HEADER_VERSION which captures the header release number independent of the spec patch number (internal issue 176). * Correct description of slink:VkPipelineShaderStageCreateInfo::pname:pName to "a pointer to a null-terminated UTF-8 string" (internal issue #197). Other Commits: * Updated DataFormat spec reference to the new date for revision 5 of that spec. * Fixed KEEP option (to retain LaTeX intermediate files) in the Makefile to be included when edited there, as well as set on the command line. * Reserve and add "VK_IMG_filter_cubic" to the registry, and implement script functionality to add and remove validity from existing functions. Includes schema and readme changes. * Update GL_KHR_vulkan_glsl so push_constants do not have descriptor sets.

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Change log for March 10, 2016 Vulkan 1.0.6 spec update: * Bump API patch number and header version number to 6 for this update. Github Issues: * Define 'invocation group' for compute and graphics shaders. Cleanup definition and use of 'workgroup', and add glossary entries (public issue 1). * Various minor editorial fixes (public issue 33). * Clarify locations for block members in the &lt;&lt;interfaces-iointerfaces-locations,Location Assignment>> section (public issue 45). * Editorial fixes for &lt;&lt;commandbuffer-allocation,Command Buffer Allocation>> section (public issues 54, 59). * Clarify behavior of depth test in the &lt;&lt;fragops-depth,Depth Test&gt;&gt; section (public issues 80, 81). * Remove discussion of return codes from flink:vkGetPhysicalDeviceSparseImageFormatProperties and flink:vkGetImageSparseMemoryRequirements, which don't return values (public issue 82). * Allow flink:vkCmdDrawIndirect and flink:vkCmdDrawIndexedIndirect pname:drawCount of 0, as well as 1, when the multiDrawIndirect feature is not supported (public issue 88). * Remove confusing wording in the &lt;&lt;features-limits,Limits>> section describing the slink:VkPhysicalDeviceLimits pname:minTexelBufferOffsetAlignment, pname:minUniformBufferOffsetAlignment, and pname:minStorageBufferOffsetAlignment members as both minimums and maximums (public issue 91). * Clarified that only the RGB components should be affected in places where sRGB is referred to in the spec, such as ASTC formats. Minor re-wording to avoid "color space" when actively incorrect, now that we refer to the Data Format Spec which actually makes a distinction between color space and transfer function (public issue 94). * Treat pname:pPropertyCount == 0 consistently in flink:vkEnumerateInstanceLayerProperties and flink:vkEnumerateDeviceLayerProperties (public issue 99) * Cleanup minor editorial issues in chapters 14-17 (public issue 100). * Clarify definition of flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties (public issue 101). * Define the flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties pname:pLayerName parameter to be a pointer to a null-terminated UTF-8 string (public issue 101). * Rearrange "Missing information" references in mandatory format tables (public issue 101). * Clarify that the enumerated extensions returned by flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties will only include extensions provided by the platform or extensions implemented in implicitly enabled layers (public issue 101). * Miscellaneous editorial fixes. Include the Vulkan spec patch number in the PDF title. Fix label on &lt;&lt;fig-non-strict-lines,Non strict lines>> diagram. Use more easily distinguished symbols in tables in the &lt;&lt;features-required-format-support,Required Format Support>> section. Don't require FQDNs used as layer names be encoded in lower case if not possible, in the &lt;&lt;extensions-naming-conventions, Extension and Layer Naming Conventions>> section (public issues 101, 119, 121). Internal Issues: * Fixed excessive spacing in tables in XHTML (internal issue 18). * Clarify that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT applies to secondary command buffers. Previously spec only referred to the members of pname:pCommandBuffers being affected by this bit. Added a separate slink:VkSubmitInfo Valid Usage restriction specifying that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT also applies to any secondary command buffers that are recorded into the primary command buffers in pname:pCommandBuffers (internal issue 106). * Clarify that slink:VkDeviceCreateInfo::pname:pEnabledFeatures can be NULL (internal issue 117). * Remove "the value of" where it is redundant (e.g. speaking of an API parameter, struct member, or SPIR-V variable, but not when speaking of color components) (internal issue 175). * Forced patch version to always be 0 in the header. Add a "VK_API_VERSION_<major>_<minor>" macro for people to use to do the right thing.

Other Commits: * Updated DataFormat spec reference to the new date for revision 5 of that spec. * Fixed KEEP option (to retain LaTeX intermediate files) in the Makefile to be included when edited there, as well as set on the command line. * Reserve and add "VK_IMG_filter_cubic" to the registry, and implement script functionality to add and remove validity from existing functions. Includes schema and readme changes. * Update GL_KHR_vulkan_glsl so push_constants do not have descriptor sets.

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for January 23, 2017 Vulkan 1.0.39 spec update: * Bump API patch number and header version number to 39 for this update. Github Issues: * Clarified that only accesses via the specified buffer/image subresource ranges are included in the access scopes (public issue 306). * Add missing valid usage statements for flink:vkCreateComputePipelines and flink:vkCreateGraphicsPipelines (public issue 427). Internal Issues: * Add a Note to the <<invariance,Invariance>> appendix about a difference between OpenGL and Vulkan with regards to how primitives derived from offsets are handled (internal issue 355). * Add the +<<VK_KHR_get_physical_device_properties2>>+, +<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+ extensions (internal issue 448). * Add the +<<VK_EXT_shader_subgroup_vote>>+ and +<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449). * Update the texture level-of-detail equation in the <<textures-scale-factor,Scale Factor Operation>> section to better approximate the ellipse major and minor axes (internal issue 547). * Forbid non-explicitly allowed uses of interface decorations in the introduction to the <<interfaces,Shader Interfaces>> chapter (internal issue 607). * Replace use of MathJax with KaTeX, for improved load-time performance as well as avoiding the scrolling-and-scrolling behavior due to MathJax asynchronous rendering when loading at an anchor inside the spec. This change also requires moving to HTML5 output for the spec instead of XHTML, and there is a visible difference in that the chapter navigation index is now in a scrollable sidebar instead of at the top of the document. We may or may not retain the nav sidebar based on feedback (internal issue 613). * Improve consistency of markup and formatting in extension appendices (internal issue 631). Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage. If the swapchain has been replaced, then it should not be passed to flink:vkAcquireNextImage. * Add a valid usage statement to flink:vkCreateImageView, that the image must have been created with an appropriate usage bit set. * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section. * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor to account for the multiple viewport feature. If the feature is not enabled, the parameters for these functions have required values that are defined in the <<features-features-multiViewport,multiple viewports>> section of the spec but were not reflected in the valid usage text for these functions. * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common color spaces.

Change log for November 25, 2016 Vulkan 1.0.35 spec update: * Bump API patch number and header version number to 35 for this update. Github Issues: * Document in the <<memory-device-hostaccess,Host Access>> section that mapping and unmapping does not invalidate or flush the mapped memory (public issues 27, 126). * Redefine the entire <<synchronization>> chapter in terms of consistent and well defined terminology, that's called out at the start of the chapter. This terminology is applied equally to all synchronization types, including subpass dependencies, submissions, and much of the implicit ordering stuff dotted around the spec. Key terms are laid out in the <<synchronization-dependencies,Execution and Memory Dependencies>> section at the top of the rewritten chapter (public issues 128, 131, 132, 217, 299, 300, 302, 306, 322, 346, 347, 371, 407). * Specify order of submission for batches in the <<vkQueueSubmit,vkQueueSubmit>> and <<vkQueueBindSparse,vkQueueBindSparse>> commands (public issue 371). * Add valid usage statements to each of the WSI extension sections indicating that the WSI-specific structure parameters must be valid, and remove automatically generated valid usage statements now covered by the manual sections (public issue 383). * Clarify render pass compatibility for flink:vkCmdExecuteCommands (public issue 390). Internal Issues: * Update +vk.xml+ to make previously explicit valid usage statements for <<vkDebugReportMessageEXT,vkDebugReportMessageEXT>> implicit instead (internal issue 553). * Add valid usage statement for slink:VkCreateImageInfo preventing creation of 1D sparse images (internal issue 573). * Fix Python scripts to always read/write files in utf-8 encoding, and a logic error in reflib.py which could cause a fatal error for malstructured asciidoc (internal issues 578, 586).

Memory Domain::
A memory domain is an abstract place to which memory writes are made
available by availability operations and memory domain operations.
The memory domains correspond to the set of agents that the write can:
then be made visible to.
The memory domains are _host_, _device_, _shader_, _workgroup instance_
(for workgroup instance there is a unique domain for each compute
workgroup) and _subgroup instance_ (for subgroup instance there is a
unique domain for each subgroup).
Memory Domain Operation::
An operation that makes the writes that are available to one memory
domain available to another memory domain.

Memory Heap::
A region of memory from which device memory allocations can: be made.

Change log for September 30, 2016 Vulkan 1.0.29 spec update: * Bump API patch number and header version number to 29 for this update. Github Issues: * Remove redundant constraint on slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue 224). * Fix typo and remove link in Note in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section (public issue 359). * Fix erroneous validation statement for the pname:layout member of slink:VkComputePipelineCreateInfo (public issue 362). Internal Issues: * Restore long figure captions using asciidoc sidebar blocks, due to restrictions of asciidoc syntax (internal issue 101). * Replace most latexmath equations with comparable markup in straight asciidoc, which significantly improves time required to fully load and process the HTML forms of the Specification. There are known minor font and alignment inconsistencies with MathJax and PDF rendering of latexmath equations. Please do not file github issues about these. We are aware of the inconsistencies and will make refinements over time, while the performance improvements are compelling in at least some major browsers (internal issue 313). * Move handcoded validity statements from +vk.xml+ into the Specification body, easing work in the single-branch model. Specify the distinction between these explicit statements, and the implicit validity statements inferred from vk.xml. Validity statements now appear in two blocks for each command and structure - handcoded "Valid Usage" and the implicit "Valid Usage (Implicit)" (internal issue 392). * Add the +returnedonly="false"+ attribute to WSI output structures, removing incorrectly generated implicit validity statements for slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR, slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR, slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures (internal issue 486). * Update slink:VkImageLayout to require the ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images (internal issue 487). * Use an explicit format specifier string for the date command invocation in the +Makefile+ instead of the shorthand -R option, which doesn't work on BSD and MaxOS X date commands (internal issue 500). Other Issues: * Use the terms ``allocation scope'' and ``extension scope'' instead of just ``scope'', and add them to the glossary.

Change log for September 19, 2018 Vulkan 1.1.85 spec update: * Update release number to 85. Public Issues: * Add self-dependency ename:VK_DEPENDENCY_BY_REGION_BIT valid usage statements for slink:VkSubpassDependency(public pull request 778). * Apply fix from pull request 742 to slink:VkSubpassDependency and slink:VkSubpassDependency2 (public pull request 779). * Specify the units of slink:VkBufferImageCopy::pname:bufferRowLength and pname:bufferImageHeight as texels (public pull request 781). * Better specify promoted parameter mapping in the `<<VK_KHR_create_renderpass2>>` appendix (public pull request 782). Internal Issues: * Only include the <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>> section in Vulkan 1.1 or later (internal issue 1381). Other Issues: * Clean up redundant valid usage language for the `VK_ANDROID_external_memory_android_hardware_buffer` extension interaction with slink:VkImageCreateInfo. * Fix error in a flag name within valid usage statements for slink:VkMemoryAllocateInfo. * Clarify that memory types are not totally ordered in slink:VkPhysicalDeviceMemoryProperties. * For slink:VkWriteDescriptorSetInlineUniformBlockEXT, set structextends="VkWriteDescriptorSet" in `vk.xml`, and make slink:VkDescriptorSetLayoutBindingFlagsCreateInfoEXT::pname:pBindingFlags optional. * Add documentation of 'provisional' XML attribute to registry.txt. New Extensions: * `VK_NV_compute_shader_derivatives` * `VK_NV_corner_sampled_image` * `VK_NV_fragment_shader_barycentric` * `VK_NV_mesh_shader` * `VK_NV_representative_fragment_test` * `VK_NV_scissor_exclusive` * `VK_NV_shader_image_footprint` * `VK_NV_shading_rate_image` * `VK_NVX_raytracing`

Change log for August 5, 2016 Vulkan 1.0.23 spec update: * Bump API patch number and header version number to 23 for this update. Github Issues: * Add explicit valid value attributes to pname:sType members in vk.xml (public issue 34). * Clarify usage of flink:vkGetInstanceProcAddr and flink:vkGetDeviceProcAddr (public issue 225). * Fix a copy-and-paste error in the description of pname:pSwapchainImageCount saying that it was the count of ``format pairs'' instead of ``swapchain images'' (public issue 292). * flink:vkCmdExecuteCommandBuffers requires all command buffers to be allocated from command pools created for the same queue family (public issue 296). * Remove bogus +optional+ attribute for flink:vkEnumerateDeviceLayerProperties::pname:physicalDevice from vk.xml (public issue 301). * Clean up the <<resources-image-views-compatibility,image and image view compatibility table>> reference and contents. Use full enumerant names. Refer to pname:layerCount in the ``view parameters'' column instead of pname:arrayLayers. Require N >= 1 for the cube array subview row, not just arrayLayers >= 6 N (public issue 304). * Modify description of <<resources-memory-aliasing,memory aliasing>> to be consistent with the description of <<resources-bufferimagegranularity,buffer image granularity>> (public issue 307). Internal Issues: * Describe remaining +vk_platform.h+ macros in the <<boilerplate,API Boilerplate>> appendix (internal issue 6). * Clarify <<features-features-robustBufferAccess,pname:robustBufferAccess>> feature behavior; what memory can be accessed, how bounds checking is performed, and allowing for vectorization (internal issue 332). * Document markup for automatic extraction of reference pages from the spec sources in the style guide (internal issue 395). * Allow flink:vkCreateDisplayModeKHR to return ename:VK_ERROR_INITIALIZAION_FAILED_KHR if the user requests mode parameters that the specified display does not support (internal issue 411). * Remove atomic counters (atomic_uint style) from KHR_vulkan_glsl, and more clearly remove the subroutine keyword alongside it (internal issue 421). * Clarify behavior of flink:vkCmdBindDescriptorSets for descriptor sets not contained in the layout (internal issue 427). Other Commits: * Change the order in which members of sname:VkAttachmentDescription and sname:VkPipelineInputAssemblyStateCreateInfo are described to match their order in the structures.

Change log for March 25, 2016 Vulkan 1.0.7 spec update: * Bump API patch number and header version number to 7 for this update. Github Issues: * Fix slink:VkSpecializationMapEntry example to avoid C/C++ strict aliasing issues (public issue 14). * Clarify the meaning of "matching" in flink:vkCmdBindDescriptorSets validity language (public issue 33). * Add stub reference pages so xrefs to not-yet-written pages don't generate 404 errors. However, the actual content of these pages still needs to be filled in as time allows (public issue 44, but does not close that issue out). * Remove incorrect validity statement for flink:vkGetImageSparseMemoryRequirements (public issue 85). * Reword the <<features-limits-bufferImageGranularity,bufferImageGranularity>> feature in terms of "aliasing", and clarify that it applies to bindings in the same memory object (public issue 90). * Clarify the relationship of the slink:VkPhysicalDeviceLimits pname:maxViewportDimensions and pname:viewportBoundsRange limits (public issue 92). * Specify sparse unbound texture replacement in the <<textures-texel-replacement,Texel Replacement>> section independently of robust buffer access language (public issue 100). * Add the <<fundamentals-architecture-model,Architecture Model>> section to explain architecture constraints Vulkan has chosen to accept in order to enable portable and performant code (public issue 122). * State that an object must not be destroyed until *all* (not *any*) uses of that object have completed (public issue 123). * Minor editorial cleanup (public issues 129, 134, 146, 148). * Add validity language for layer and extension names to slink:VkDeviceCreateInfo matching that used for slink:VkInstanceCreateInfo (public issue 130). * Clean up terminology for the case when the bits set in one bitmask are a subset of the bits set in another bitmask (public issue 138). * Document that input attachments are UniformConstant not Input, in the <<interfaces-inputattachment,Fragment Input Attachment Interface>> section (public glslang bug 169). Internal Issues: * Add max enum values to "flag bits" enums (internal issue #136). * Clarify language around the various uses of the term "block" in the <<appendix-compressedtex-bc,Block Compressed Image Formats>> section (internal issue #202). * Removed "expand" dependency from <enums> groups in vk.xml and added auto-generation code in the scripts to infer it instead, to ensure consistency. This caused renaming of sname:VkColorSpaceKHR and sname:VkPresentModeKHR etext:BEGIN_RANGE (etc.) tokens, but those tokens are metadata, not part of the API, and the Vulkan WG is OK with this change. This change adds ranges to two additional enums that were missing them due to not defining the "expand" attribute (internal issue 217). * Tweak makefile to generate ref page nroff (.3) files in the right output directory, working around an a2x limitation (internal issue 223). Other Commits: * Add validity requirements for flink:vkCmdCopyQueryPoolResults pname:dstBuffer parameter. * Fix ref page build to generate .3 targets in the right output directory.

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Github Issues: * Provide alternate length attributes (altlen=) in the XML schema, for those using length attributes to generate code instead of documentation (public issue 555). * Fix erroneous references to `latex:` being used for asciidoc math markup, rather than `latexmath:` (public pull request 556). * Add author ID to XML for Kazan software renderer (public pull request 557). Internal Issues: * Add the <<fundamentals-abi,Application Binary Interface>> section describing platform ABI requirements and recommendations, add examples of function and function pointer declarations to the <<boilerplate-platform-specific-calling-conventions, Platform-Specific Calling Conventions>> section, and remove related language that existed elsewhere in the specification (internal issue 64). * Describe where to document valid usage interactions of chained structures in the style guide, and fix one case now appearing in slink:VkBufferCreateInfo instead of the child slink:VkDedicatedAllocationBufferCreateInfoNV structure (internal issue 715). * Add example to the style guide of describing enumerated types which are empty when the spec is built without relevant extensions enabled, and apply it to existing examples for elink:VkDescriptorSetLayoutCreateFlagBits and elink:VkSubpassDescriptionFlagBits (internal issue 864). * Add a note to the <<fundamentals-validusage-enums, Valid Usage for Enumerated Types>> section that the special values suffixed with etext:_BEGIN_RANGE, etext:_END_RANGE, etext:_RANGE_SIZE and etext:_MAX_ENUM are not part of the API and should: not be used by applications (internal issue 872). * Added note to flink:vkCmdUpdateBuffers explaining the performance penalty for copies done in this way, and why the upper copy limit is what it is (internal issue 952). * Update `VK_KHX_device_group` to split some functionality into the new `VK_KHR_bind_memory2` extension, and rename that functionality (internal issue 969). * Remove *Status* fields from extension appendices, since they are by definition published and complete by the time they reach the public github repository (internal issue 973). Other Issues: * Update Data Format specification dependency to version 1.2 and change references to DF sections accordingly. * Update XML to make the pname:pAllocator parameter of flink:vkRegisterDeviceEventEXT and flink:vkRegisterDisplayEventEXT in the `VK_EXT_display_control` extension as optional.

Change log for March 3, 2019 Vulkan 1.1.102 spec update: * Update release number to 102. Public Issues: * Simplify flink:vkGetImageMemoryRequirements constraint for ename:VK_MEMORY_PROPERTY_LAZILY_ALLOCATED_BIT (public pull request 817). * Fix typo in markup of the <<textures-texel-coordinate-systems-diagrams, Texel Coordinate Systems, Corner Sampling>> image that was generating complaints from chunked HTML output generation (public pull request 928). Internal Issues: * Split the old <<features, Features>> chapter into four chapters: <<features, Features>>, <<limits, Limits>>, <<formats, Formats>>, and <<capabilities, Capabilities>>, with minor edits to the introductory paragraph of each chapter. Anchor names in these chapters were changed, with corresponding effects to xrefs to these anchors elsewhere in spec markup . The purpose is to make the chunked HTML spec output load faster on what was previously a single, gigantic chapter (internal issue 1554). * Add ename:VK_PIPELINE_STAGE_RAY_TRACING_SHADER_BIT_NV, to the supported pipeline stages for ename:VK_ACCESS_UNIFORM_READ, ename:VK_ACCESS_SHADER_READ, and ename:VK_ACCESS_SHADER_WRITE in the <<synchronization-access-types-supported>> table. * Correct legal name of Google, LLC in vk.xml \<tags> section and a copyright statement. * Clarify that Vulkan treats the Android code:AHARDWAREBUFFER_FORMAT_R8G8B8X8_UNORM format as RGBA, and the application is responsible for forcing the X/A component to be read as 1.0, in the <<memory-external-android-hardware-buffer-formats>> table. * Clarify the vertex order of various primitive topologies, and define the order of transform feedback vertex capture based on that. This involves a lot of refactoring and cleanup in the <<drawing-primitive-topologies, Primitive Topologies>>, <<geometry-input, Geometry Shader Input Primitives>> sections, and <<vertexpostproc-transform-feedback Transform Feedback>> sections, and numerous places in the <<tessellation>> chapter, New Extensions: * `VK_EXT_metal_surface` * `VK_EXT_ycbcr_image_arrays` (internal issue 1361). * `VK_NVX_image_view_handle`

Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Internal Issues: * Add the <<fundamentals-abi,Application Binary Interface>> section describing platform ABI requirements and recommendations, add examples of function and function pointer declarations to the <<boilerplate-platform-specific-calling-conventions, Platform-Specific Calling Conventions>> section, and remove related language that existed elsewhere in the specification (internal issue 64). * Describe where to document valid usage interactions of chained structures in the style guide, and fix one case now appearing in slink:VkBufferCreateInfo instead of the child slink:VkDedicatedAllocationBufferCreateInfoNV structure (internal issue 715). * Add example to the style guide of describing enumerated types which are empty when the spec is built without relevant extensions enabled, and apply it to existing examples for elink:VkDescriptorSetLayoutCreateFlagBits and elink:VkSubpassDescriptionFlagBits (internal issue 864). * Add a note to the <<fundamentals-validusage-enums, Valid Usage for Enumerated Types>> section that the special values suffixed with etext:_BEGIN_RANGE, etext:_END_RANGE, etext:_RANGE_SIZE and etext:_MAX_ENUM are not part of the API and should: not be used by applications (internal issue 872). * Added note to flink:vkCmdUpdateBuffers explaining the performance penalty for copies done in this way, and why the upper copy limit is what it is (internal issue 952). * Update `VK_KHX_device_group` to split some functionality into the new `VK_KHR_bind_memory2` extension, and rename that functionality (internal issue 969). * Remove *Status* fields from extension appendices, since they are by definition published and complete by the time they reach the public github repository (internal issue 973). Other Issues: * Update Data Format specification dependency to version 1.2 and change references to DF sections accordingly. * Update XML to make the pname:pAllocator parameter of flink:vkRegisterDeviceEventEXT and flink:vkRegisterDisplayEventEXT in the `VK_EXT_display_control` extension as optional. New Extensions: * `VK_KHR_bind_memory2` * `VK_KHR_image_format_list` * `VK_KHR_maintenance2` * `VK_KHR_sampler_ycbcr_conversion`

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for September 30, 2016 Vulkan 1.0.29 spec update: * Bump API patch number and header version number to 29 for this update. Github Issues: * Remove redundant constraint on slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue 224). * Fix typo and remove link in Note in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section (public issue 359). * Fix erroneous validation statement for the pname:layout member of slink:VkComputePipelineCreateInfo (public issue 362). Internal Issues: * Restore long figure captions using asciidoc sidebar blocks, due to restrictions of asciidoc syntax (internal issue 101). * Replace most latexmath equations with comparable markup in straight asciidoc, which significantly improves time required to fully load and process the HTML forms of the Specification. There are known minor font and alignment inconsistencies with MathJax and PDF rendering of latexmath equations. Please do not file github issues about these. We are aware of the inconsistencies and will make refinements over time, while the performance improvements are compelling in at least some major browsers (internal issue 313). * Move handcoded validity statements from +vk.xml+ into the Specification body, easing work in the single-branch model. Specify the distinction between these explicit statements, and the implicit validity statements inferred from vk.xml. Validity statements now appear in two blocks for each command and structure - handcoded "Valid Usage" and the implicit "Valid Usage (Implicit)" (internal issue 392). * Add the +returnedonly="false"+ attribute to WSI output structures, removing incorrectly generated implicit validity statements for slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR, slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR, slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures (internal issue 486). * Update slink:VkImageLayout to require the ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images (internal issue 487). * Use an explicit format specifier string for the date command invocation in the +Makefile+ instead of the shorthand -R option, which doesn't work on BSD and MaxOS X date commands (internal issue 500). Other Issues: * Use the terms ``allocation scope'' and ``extension scope'' instead of just ``scope'', and add them to the glossary.

Key terms are laid out in the <<synchronization-dependencies,Execution and Memory Dependencies>> section at the top of the rewritten chapter (public issues 128, 131, 132, 217, 299, 300, 302, 306, 322, 346, 347, 371, 407). * Specify order of submission for batches in the <<vkQueueSubmit,vkQueueSubmit>> and <<vkQueueBindSparse,vkQueueBindSparse>> commands (public issue 371). * Add valid usage statements to each of the WSI extension sections indicating that the WSI-specific structure parameters must be valid, and remove automatically generated valid usage statements now covered by the manual sections (public issue 383). * Clarify render pass compatibility for flink:vkCmdExecuteCommands (public issue 390). Internal Issues: * Update +vk.xml+ to make previously explicit valid usage statements for <<vkDebugReportMessageEXT,vkDebugReportMessageEXT>> implicit instead (internal issue 553). * Add valid usage statement for slink:VkCreateImageInfo preventing creation of 1D sparse images (internal issue 573). * Fix Python scripts to always read/write files in utf-8 encoding, and a logic error in reflib.py which could cause a fatal error for malstructured asciidoc (internal issues 578, 586).

Public Issues: * Add a note to the <<features-required-format-support, Required Format Support>> section clarifying that the required formats don't depend on the used flags (public issue 671). * Add a valid usage statement for flink:vkUpdateDescriptors that was previously described for slink:VkImageSubresourceRange, but not as a valid usage statement (public issue 713). * Modify implicit valid usage generator script to not emit 'must: not be 0' for a parameter that is a pointer to a flags field, such as pname:pPeerMemoryFeatures (public issue 729). Internal Issues: * Add definitions of "`obsoleted`" and "`deprecated`", and modify the definition of "`promoted`" in the <<glossary, Glossary>> (internal issue 988). * Add language for integer texel output conversions (the conversion is undefined) to the <<textures-output-format-conversion]] Texel Output Format Conversion>> section. Simplify and clarify the floating-point conversion language in the <<fundamentals-general, General Requirements>> section and the new <<fundamentals-fp-conversion, Floating-Point Format Conversions>> section, and remove obsolete language in the format-specific floating-point sections (internal issue 1275). * Add the elink:VkVendorId enumerated type to the Vulkan API / XML / header, so reserved Khronos vendor IDs can be referred to symbolically by clients. Note that only Khronos vendor IDs (e.g. non-PCI vendor IDs) are defined (internal issue 1299). * Fix typo in the <<fig-non-strict-lines, Non strict lines>> table (internal issue 1315). * Clean up and simplify the <<features-formats-requiring-sampler-ycbcr-conversion, YCbCr format properties>> table and use symbols consistently with other tables.

Change log for April 15, 2016 Vulkan 1.0.10 spec update: * Bump API patch number and header version number to 10 for this update. Github Issues: * Slightly tweak the <<memory-allocation,Host Memory>> allocator language so that an application wrapping the standard C alloc/free/realloc functions is still correct - the previous language was too strong with regards to freeing memory. Also made certain scenarios clearer - an implementation may now continue without error if an allocation failed and it is able to continue correctly (public issue 21). * Require that etext:VK_*_CREATE_SPARSE_BINDING_BIT is set when the corresponding etext:VK_*_CREATE_SPARSE_RESIDENCY_BIT is used, in the <<sparsememory-miptail,Mip Tail Regions>> section and related commands flink:vkCreateBuffer and flink:vkCreateImage (public issue 84). * Update the <<features,Features, Limits, and Formats>> chapter to clarify interactions between optional features and dynamic state for the pname:depthBiasClamp and pname:wideLines features (public issue 89). * Describe the code:WorkgroupSize builtin in the <<interfaces-builtin-variables,Built-In Variables>> section, and update the <<compute-shaders,Compute Shaders>> section to further clarify how to set the number of workgroups to execute in a compute shader (public issue 145). * Use the term *image subresource* everywhere instead of *subresource*, except for the special case of *host-accessible subresource*, which may be either an image subresource or buffer range (public issue 120) * Add a note to the <<features,Features, Limits, and Formats>> section about extensibility of structures (Public issue 165). * Fix return code flink:vkAcquireNextImageKHR when the timeout parameter is 0 to ename:VK_NOT_READY instead of ename:VK_TIMEOUT (public issue 170). * Fix typo in slink:VkLayerProperties::pname:apiVersion field (public issue 172).

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Github Issues: * Changed asciidoctor macros so cross-page links in the standalone reference pages function properly (public issue 462). Internal Issues: * Clarified host visibility discussion for slink:VkMemoryType, flink:vkInvalidateMappedMemoryRanges, elink:VkAccessFlagBits, and the <<synchronization-framebuffer-regions,Framebuffer Region Dependencies>> section, removing duplicated information and adding a central definition in the access types section (internal issue 552). * Change description of slink:vkGetPhysicalDeviceSurfacePresentModesKHR::pname:pPresentModes to return an array of values, not structures (internal issue 699). New Extensions: * Add a NOTE to the <<extensions,Layers & Extensions>> chapter describing the experimental status of `KHX` extensions. * Add new Khronos, Khronos Experimental, and vendor Vulkan extensions for release at GDC: ** VK_KHR_descriptor_update_template ** VK_KHR_push_descriptor ** VK_KHX_device_group ** VK_KHX_device_group_creation ** VK_KHX_external_memory ** VK_KHX_external_memory_capabilities ** VK_KHX_external_memory_fd ** VK_KHX_external_memory_win32 ** VK_KHX_external_semaphore ** VK_KHX_external_semaphore_capabilities ** VK_KHX_external_semaphore_fd ** VK_KHX_external_semaphore_win32 ** VK_KHX_multiview ** VK_KHX_win32_keyed_mutex ** VK_EXT_discard_rectangles ** VK_MVK_ios_surface ** VK_MVK_macos_surface ** VK_NVX_multiview_per_view_attributes ** VK_NV_clip_space_w_scaling ** VK_NV_geometry_shader_passthrough ** VK_NV_sample_mask_override_coverage ** VK_NV_viewport_array2 ** VK_NV_viewport_swizzle * Add new GLSL vendor extensions to support new builtin variables: ** GL_EXT_device_group ** GL_EXT_multiview

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for January 23, 2017 Vulkan 1.0.39 spec update: * Bump API patch number and header version number to 39 for this update. Github Issues: * Clarified that only accesses via the specified buffer/image subresource ranges are included in the access scopes (public issue 306). * Add missing valid usage statements for flink:vkCreateComputePipelines and flink:vkCreateGraphicsPipelines (public issue 427). Internal Issues: * Add a Note to the <<invariance,Invariance>> appendix about a difference between OpenGL and Vulkan with regards to how primitives derived from offsets are handled (internal issue 355). * Add the +<<VK_KHR_get_physical_device_properties2>>+, +<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+ extensions (internal issue 448). * Add the +<<VK_EXT_shader_subgroup_vote>>+ and +<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449). * Update the texture level-of-detail equation in the <<textures-scale-factor,Scale Factor Operation>> section to better approximate the ellipse major and minor axes (internal issue 547). * Forbid non-explicitly allowed uses of interface decorations in the introduction to the <<interfaces,Shader Interfaces>> chapter (internal issue 607). * Replace use of MathJax with KaTeX, for improved load-time performance as well as avoiding the scrolling-and-scrolling behavior due to MathJax asynchronous rendering when loading at an anchor inside the spec. This change also requires moving to HTML5 output for the spec instead of XHTML, and there is a visible difference in that the chapter navigation index is now in a scrollable sidebar instead of at the top of the document. We may or may not retain the nav sidebar based on feedback (internal issue 613). * Improve consistency of markup and formatting in extension appendices (internal issue 631). Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage. If the swapchain has been replaced, then it should not be passed to flink:vkAcquireNextImage. * Add a valid usage statement to flink:vkCreateImageView, that the image must have been created with an appropriate usage bit set. * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section. * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor to account for the multiple viewport feature. If the feature is not enabled, the parameters for these functions have required values that are defined in the <<features-features-multiViewport,multiple viewports>> section of the spec but were not reflected in the valid usage text for these functions. * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common color spaces.

Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for January 23, 2017 Vulkan 1.0.39 spec update: * Bump API patch number and header version number to 39 for this update. Github Issues: * Clarified that only accesses via the specified buffer/image subresource ranges are included in the access scopes (public issue 306). * Add missing valid usage statements for flink:vkCreateComputePipelines and flink:vkCreateGraphicsPipelines (public issue 427). Internal Issues: * Add a Note to the <<invariance,Invariance>> appendix about a difference between OpenGL and Vulkan with regards to how primitives derived from offsets are handled (internal issue 355). * Add the +<<VK_KHR_get_physical_device_properties2>>+, +<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+ extensions (internal issue 448). * Add the +<<VK_EXT_shader_subgroup_vote>>+ and +<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449). * Update the texture level-of-detail equation in the <<textures-scale-factor,Scale Factor Operation>> section to better approximate the ellipse major and minor axes (internal issue 547). * Forbid non-explicitly allowed uses of interface decorations in the introduction to the <<interfaces,Shader Interfaces>> chapter (internal issue 607). * Replace use of MathJax with KaTeX, for improved load-time performance as well as avoiding the scrolling-and-scrolling behavior due to MathJax asynchronous rendering when loading at an anchor inside the spec. This change also requires moving to HTML5 output for the spec instead of XHTML, and there is a visible difference in that the chapter navigation index is now in a scrollable sidebar instead of at the top of the document. We may or may not retain the nav sidebar based on feedback (internal issue 613). * Improve consistency of markup and formatting in extension appendices (internal issue 631). Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage. If the swapchain has been replaced, then it should not be passed to flink:vkAcquireNextImage. * Add a valid usage statement to flink:vkCreateImageView, that the image must have been created with an appropriate usage bit set. * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section. * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor to account for the multiple viewport feature. If the feature is not enabled, the parameters for these functions have required values that are defined in the <<features-features-multiViewport,multiple viewports>> section of the spec but were not reflected in the valid usage text for these functions. * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common color spaces.

Change log for November 25, 2016 Vulkan 1.0.35 spec update: * Bump API patch number and header version number to 35 for this update. Github Issues: * Document in the <<memory-device-hostaccess,Host Access>> section that mapping and unmapping does not invalidate or flush the mapped memory (public issues 27, 126). * Redefine the entire <<synchronization>> chapter in terms of consistent and well defined terminology, that's called out at the start of the chapter. This terminology is applied equally to all synchronization types, including subpass dependencies, submissions, and much of the implicit ordering stuff dotted around the spec. Key terms are laid out in the <<synchronization-dependencies,Execution and Memory Dependencies>> section at the top of the rewritten chapter (public issues 128, 131, 132, 217, 299, 300, 302, 306, 322, 346, 347, 371, 407). * Specify order of submission for batches in the <<vkQueueSubmit,vkQueueSubmit>> and <<vkQueueBindSparse,vkQueueBindSparse>> commands (public issue 371). * Add valid usage statements to each of the WSI extension sections indicating that the WSI-specific structure parameters must be valid, and remove automatically generated valid usage statements now covered by the manual sections (public issue 383). * Clarify render pass compatibility for flink:vkCmdExecuteCommands (public issue 390). Internal Issues: * Update +vk.xml+ to make previously explicit valid usage statements for <<vkDebugReportMessageEXT,vkDebugReportMessageEXT>> implicit instead (internal issue 553). * Add valid usage statement for slink:VkCreateImageInfo preventing creation of 1D sparse images (internal issue 573). * Fix Python scripts to always read/write files in utf-8 encoding, and a logic error in reflib.py which could cause a fatal error for malstructured asciidoc (internal issues 578, 586).

Internal Issues: * Added validation language for flink:vkCmdWaitEvents, flink:vkQueueSubmit, flink:VkRenderPassCreateInfo, and in the <<synchronization-pipeline-stages-supported>> section to prevent recording stage dependencies that aren't supported on the queue (internal issue 516). * Make a few changes that generalize spec language for use with possible future extensions by adding glossary terms and generalizing ``feature'' to ``feature or extension'' where relevant (internal issues 448, 590). * Added "pipeline type" attribute to +vk.xml+ for relevant commands and utilize it in automatic generation of the Command Properties table (internal issue 517). * Specify that WSI implementations must provide both UNORM and sRGB formats in the description of slink:VkColorSpaceKHR (internal issue 529). * Remove nesting of explicit valid usage statements where it is not meaningful (internal issue 583). Other Issues: * Add validity language requiring that slink:VkPushConstantRange::pname:offset be a multiple of 4, as stated in the spec language.

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Planar::
See _multi-planar_.
Plane::
An _image plane_ is part of the representation of an image, containing a
subset of the color channels required to represent the texels in the
image and with a contiguous mapping of coordinates to bound memory.
Most images consist only of a single plane, but some formats spread the
channels across multiple image planes.
The host-accessible properties of each image plane are accessed in a
linear layout using flink:vkGetImageSubresourceLayout.

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Point Sampling (Rasterization)::
A rule that determines whether a fragment sample location is covered by
a polygon primitive by testing whether the sample location is in the
interior of the polygon in framebuffer-space, or on the boundary of the
polygon according to the tie-breaking rules.
Change log for February 10, 2017 Vulkan 1.0.40 spec update: * Bump API patch number and header version number to 40 for this update. * There is a major build change in this release. We are now using the Ruby-based ``asciidoctor'' implementation, rather than the Python-based ``asciidoc'' implementation, to process the specification. While the actual specification markup changes were minimal, this requires a new set of build tools and a very different installation process, especially because we now use an experimental direct-to-PDF backend for Asciidoctor instead of Docbook->dblatex->PDF. It is no longer possible to build the Specification using asciidoc. See doc/specs/vulkan/README.adoc for some guidance on installing the new toolchain components. * There are some minor rendering issues in the PDF output due to teething problems with the asciidoctor toolchain, especially with mathematical equations. We are aware of these and working on them. Github Issues: * Updated sample code for the <<sparsememory-examples-basic,sparse resource binding example>> (public issue 97). * Modify line and point clipping behavior in the <<vertexpostproc-clipping, Primitive Clipping>> section to allow for pop-free behavior. The ability to check for which behavior is implemented may be added a future feature or extension (public issue 113). * Unify the discussions of implicit ordering throughout the spec, in particular in the new sections <<drawing-primitive-order, Primitive Order>>, <<primrast-order, Rasterization Order>>, and <<synchronization-implicit, Implicit Synchronization Guarantees>>; the discussion of <<synchronization-submission-order, submission order>>; and references elsewhere to these sections (public issue 133). * Clarify \<\<descriptorsets-compatibility,Pipeline Layout Compatibility>> language and introduce the term ``identically defined'' (public issue 164). * Add a dependency to the +VK_EXT_debug_marker+ extension that's needed to reuse the object type enum from +VK_EXT_debug_report+, and moves the definition of that enum into +VK_EXT_debug_report+ where it should be (public issue 409). * Remove redundant valid usage statement from slink:VkImageBlit (public issue 421). * Update GL_KHR_vulkan_glsl to allow the ternary operator to result in a specialization constant (public issue 424). * Fix valid usage for flink:VkPipelineShaderStageCreateInfo (public issue 426). * Correct typo in New Objects list for <<VK_EXT_debug_report>> (public issue 447). Internal Issues: * Moved to asciidoctor for spec builds (internal issue 121). * Update style guide to describe where to put new extensions-specific asciidoc files, and what to name them (internal issue 626). * Add src/spec/indexExt.py to autogenerate registry index entries linking into the 1.0-extensions specification, instead of maintaining the index manually. (internal issue 642). * Autogenerate extension dependencies and lists of all extensions and all KHR extensions from the "supported" attributes in +vk.xml+. Execute +make config/extDependency.sh+ from +doc/specs/vulkan+ when a supported extension is added to vk.xml, to regenerate the dependency script. The consequence is that specifying a single extension to the +makeExt+ script will automatically enable all extensions it depends on as well, and that the +makeAllExts+ and +makeKHR+ scripts do not need to be updated when a new extension is supported (internal issue 648). * Put extension appendices all at the same asciidoc section level, so KHR WSI extensions show up in the HTML index (internal issue 648). Other Issues: * Imbed images in the generated HTML specs instead of loading them from the images/ directory. * Fix missing EXT in extension name (ename:VK_EXT_SWAPCHAIN_COLOR_SPACE_EXTENSION_NAME). * Add new +VK_EXT_SMPTE_2086_metadata+ extension. * In the <<platformCreateSurface_xlib,Xlib Surface>> section of the +VK_KHR_xlib_surface+ specification, add language warning users that they always need to call code:XinitThreads. * Use the term "presentable image" (rather than "swapchain image") consistently in +VK_KHR_swapchain+ and related extensions, and add a glossary term defining it. * Relocate the valid usage for samples of flink:vkGetPhysicalDeviceSparseImageFormatProperties2KHR::pname:pFormatInfo to be below the flink:VkPhysicalDeviceSparseImageFormatInfo2KHR structure.

See doc/specs/vulkan/README.adoc for some guidance on installing the new toolchain components. * There are some minor rendering issues in the PDF output due to teething problems with the asciidoctor toolchain, especially with mathematical equations. We are aware of these and working on them. Github Issues: * Updated sample code for the <<sparsememory-examples-basic,sparse resource binding example>> (public issue 97). * Modify line and point clipping behavior in the <<vertexpostproc-clipping, Primitive Clipping>> section to allow for pop-free behavior. The ability to check for which behavior is implemented may be added a future feature or extension (public issue 113). * Unify the discussions of implicit ordering throughout the spec, in particular in the new sections <<drawing-primitive-order, Primitive Order>>, <<primrast-order, Rasterization Order>>, and <<synchronization-implicit, Implicit Synchronization Guarantees>>; the discussion of <<synchronization-submission-order, submission order>>; and references elsewhere to these sections (public issue 133). * Clarify \<\<descriptorsets-compatibility,Pipeline Layout Compatibility>> language and introduce the term ``identically defined'' (public issue 164). * Add a dependency to the +VK_EXT_debug_marker+ extension that's needed to reuse the object type enum from +VK_EXT_debug_report+, and moves the definition of that enum into +VK_EXT_debug_report+ where it should be (public issue 409). * Remove redundant valid usage statement from slink:VkImageBlit (public issue 421). * Update GL_KHR_vulkan_glsl to allow the ternary operator to result in a specialization constant (public issue 424). * Fix valid usage for flink:VkPipelineShaderStageCreateInfo (public issue 426). * Correct typo in New Objects list for <<VK_EXT_debug_report>> (public issue 447). Internal Issues: * Moved to asciidoctor for spec builds (internal issue 121). * Update style guide to describe where to put new extensions-specific asciidoc files, and what to name them (internal issue 626). * Add src/spec/indexExt.py to autogenerate registry index entries linking into the 1.0-extensions specification, instead of maintaining the index manually. (internal issue 642). * Autogenerate extension dependencies and lists of all extensions and all KHR extensions from the "supported" attributes in +vk.xml+. Execute +make config/extDependency.sh+ from +doc/specs/vulkan+ when a supported extension is added to vk.xml, to regenerate the dependency script. The consequence is that specifying a single extension to the +makeExt+ script will automatically enable all extensions it depends on as well, and that the +makeAllExts+ and +makeKHR+ scripts do not need to be updated when a new extension is supported (internal issue 648). * Put extension appendices all at the same asciidoc section level, so KHR WSI extensions show up in the HTML index (internal issue 648). Other Issues: * Imbed images in the generated HTML specs instead of loading them from the images/ directory. * Fix missing EXT in extension name (ename:VK_EXT_SWAPCHAIN_COLOR_SPACE_EXTENSION_NAME). * Add new +VK_EXT_SMPTE_2086_metadata+ extension. * In the <<platformCreateSurface_xlib,Xlib Surface>> section of the +VK_KHR_xlib_surface+ specification, add language warning users that they always need to call code:XinitThreads. * Use the term "presentable image" (rather than "swapchain image") consistently in +VK_KHR_swapchain+ and related extensions, and add a glossary term defining it. * Relocate the valid usage for samples of flink:vkGetPhysicalDeviceSparseImageFormatProperties2KHR::pname:pFormatInfo to be below the flink:VkPhysicalDeviceSparseImageFormatInfo2KHR structure.

Change log for September 30, 2016 Vulkan 1.0.29 spec update: * Bump API patch number and header version number to 29 for this update. Github Issues: * Remove redundant constraint on slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue 224). * Fix typo and remove link in Note in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section (public issue 359). * Fix erroneous validation statement for the pname:layout member of slink:VkComputePipelineCreateInfo (public issue 362). Internal Issues: * Restore long figure captions using asciidoc sidebar blocks, due to restrictions of asciidoc syntax (internal issue 101). * Replace most latexmath equations with comparable markup in straight asciidoc, which significantly improves time required to fully load and process the HTML forms of the Specification. There are known minor font and alignment inconsistencies with MathJax and PDF rendering of latexmath equations. Please do not file github issues about these. We are aware of the inconsistencies and will make refinements over time, while the performance improvements are compelling in at least some major browsers (internal issue 313). * Move handcoded validity statements from +vk.xml+ into the Specification body, easing work in the single-branch model. Specify the distinction between these explicit statements, and the implicit validity statements inferred from vk.xml. Validity statements now appear in two blocks for each command and structure - handcoded "Valid Usage" and the implicit "Valid Usage (Implicit)" (internal issue 392). * Add the +returnedonly="false"+ attribute to WSI output structures, removing incorrectly generated implicit validity statements for slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR, slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR, slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures (internal issue 486). * Update slink:VkImageLayout to require the ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images (internal issue 487). * Use an explicit format specifier string for the date command invocation in the +Makefile+ instead of the shorthand -R option, which doesn't work on BSD and MaxOS X date commands (internal issue 500). Other Issues: * Use the terms ``allocation scope'' and ``extension scope'' instead of just ``scope'', and add them to the glossary.

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Change log for July 1, 2018 Vulkan 1.1.79 spec update: * Update release number to 79. Public Issues: * Add a note to the <<features-required-format-support, Required Format Support>> section clarifying that the required formats don't depend on the used flags (public issue 671). * Add a valid usage statement for flink:vkUpdateDescriptors that was previously described for slink:VkImageSubresourceRange, but not as a valid usage statement (public issue 713). * Modify implicit valid usage generator script to not emit 'must: not be 0' for a parameter that is a pointer to a flags field, such as pname:pPeerMemoryFeatures (public issue 729). Internal Issues: * Add definitions of "`obsoleted`" and "`deprecated`", and modify the definition of "`promoted`" in the <<glossary, Glossary>> (internal issue 988). * Add language for integer texel output conversions (the conversion is undefined) to the <<textures-output-format-conversion]] Texel Output Format Conversion>> section. Simplify and clarify the floating-point conversion language in the <<fundamentals-general, General Requirements>> section and the new <<fundamentals-fp-conversion, Floating-Point Format Conversions>> section, and remove obsolete language in the format-specific floating-point sections (internal issue 1275). * Add the elink:VkVendorId enumerated type to the Vulkan API / XML / header, so reserved Khronos vendor IDs can be referred to symbolically by clients. Note that only Khronos vendor IDs (e.g. non-PCI vendor IDs) are defined (internal issue 1299). * Fix typo in the <<fig-non-strict-lines, Non strict lines>> table (internal issue 1315). * Clean up and simplify the <<features-formats-requiring-sampler-ycbcr-conversion, YCbCr format properties>> table and use symbols consistently with other tables. Add a column for the number of planes. * Add code:Float16 to the <<spirvenv-capabilities-table, List of optional SPIR-V capabilities>> for the `VK_AMD_gpu_shader_half_float` extension.

There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Change log for September 6, 2016 Vulkan 1.0.26 spec update: * Bump API patch number and header version number to 26 for this update. Github Issues: * Bring sample code in the +VK_KHR_surface+ and +VK_KHR_swapchain+ extension summary appendices up to date, and note they will be replaced with pointers to the LunarG SDK examples in the future (public issue 279). * Add a new <<fundamentals-commandsyntax-results-lifetime,Lifetime of Retrieved Results>> section specifying that ftext:vkGet* and ftext:VkEnumerate* results are invariant unless otherwise specified, and specify behavior for individual commands which are not invariant (public issue 280). * Remove conflicting definition of slink:VkDisplayPlaneCapabilitiesKHR::pname:maxSrcPosition and clean up language of the remaining definition (public issue 351). * Fix many minor spelling errors and add rules to the style guide to prevent recurrences (public issue 352). Internal Issues: * Remove redundant descriptions of the etext:VK_USE_PLATFORM_* macros from the <<wsi,Window System Integration>> chapter in favor of the description in the <<boilerplate-wsi-header,Window System-Specific Header Control>> appendix (internal issue 6). * Replace misleading 'can: be destroyed when not X' with more correct 'must: not be destroyed while X' in the <<fundamentals-objectmodel-lifetime,Object Lifetime>> section. Disallow destroying a pipeline layout while a command buffer using it is recording (internal issue 241). * Clarify that ename:VK_IMAGE_USAGE_TRANSIENT_ATTACHMENT_BIT is valid for all images used as attachments in elink:VkImageUsageFlagBits and the slink:VkImageLayout validity language (internal issue 320). * Note that <<extended-functionality-layers,Layers>> may wrap object handles, but that this is a generally discouraged. A link to additional information in the documentation for layer authors is provided (issue 398) * Replace the mustnot: and shouldnot: macros with equivalent must: not and should: not to get rid of non-English words while still highlighting normative language (internal issue 407). * Disallow creating multisampled images with ename:VK_IMAGE_CREATE_CUBE_COMPATIBLE_BIT in the slink:VkImageLayout validity language and the <<features-supported-sample-counts,Supported Sample Counts>> section (internal issue 445). * Fix typo so that flink:vkCmdDrawIndexedIndirect is defined in terms of flink:vkCmdDrawIndexed rather than flink:vkCmdDrawIndirect (internal issue 446). * Reorganize the per-extension information sections to all be in the <<extensions,Layers & Extensions>> appendix. Also fix a typo in +VK_IMG_filter_cubic+ which incorrectly identified it as a +KHR+ extension (internal issue 461). Other Issues: * Use asciidoc markup instead of latexmath to simplify diagrams in the <<features-formats-non-packed,byte mapping tables>> for color formats. * Fix a markup problem with the wildcarded enumerant names in a NOTE in the <<textures-texel-replacement,Texel Replacement>> section. * Fix missing attributes in the XML interface for elink:VkExternalMemoryHandleTypeFlagBitsNV and elink:VkExternalMemoryFeatureFlagBitsNV (KhronosGroup/Vulkan-Hpp issue #25) * Cleanup reference page builds so only core pages are built for releases.

Change log for February 10, 2017 Vulkan 1.0.40 spec update: * Bump API patch number and header version number to 40 for this update. * There is a major build change in this release. We are now using the Ruby-based ``asciidoctor'' implementation, rather than the Python-based ``asciidoc'' implementation, to process the specification. While the actual specification markup changes were minimal, this requires a new set of build tools and a very different installation process, especially because we now use an experimental direct-to-PDF backend for Asciidoctor instead of Docbook->dblatex->PDF. It is no longer possible to build the Specification using asciidoc. See doc/specs/vulkan/README.adoc for some guidance on installing the new toolchain components. * There are some minor rendering issues in the PDF output due to teething problems with the asciidoctor toolchain, especially with mathematical equations. We are aware of these and working on them. Github Issues: * Updated sample code for the <<sparsememory-examples-basic,sparse resource binding example>> (public issue 97). * Modify line and point clipping behavior in the <<vertexpostproc-clipping, Primitive Clipping>> section to allow for pop-free behavior. The ability to check for which behavior is implemented may be added a future feature or extension (public issue 113). * Unify the discussions of implicit ordering throughout the spec, in particular in the new sections <<drawing-primitive-order, Primitive Order>>, <<primrast-order, Rasterization Order>>, and <<synchronization-implicit, Implicit Synchronization Guarantees>>; the discussion of <<synchronization-submission-order, submission order>>; and references elsewhere to these sections (public issue 133). * Clarify \<\<descriptorsets-compatibility,Pipeline Layout Compatibility>> language and introduce the term ``identically defined'' (public issue 164). * Add a dependency to the +VK_EXT_debug_marker+ extension that's needed to reuse the object type enum from +VK_EXT_debug_report+, and moves the definition of that enum into +VK_EXT_debug_report+ where it should be (public issue 409). * Remove redundant valid usage statement from slink:VkImageBlit (public issue 421). * Update GL_KHR_vulkan_glsl to allow the ternary operator to result in a specialization constant (public issue 424). * Fix valid usage for flink:VkPipelineShaderStageCreateInfo (public issue 426). * Correct typo in New Objects list for <<VK_EXT_debug_report>> (public issue 447). Internal Issues: * Moved to asciidoctor for spec builds (internal issue 121). * Update style guide to describe where to put new extensions-specific asciidoc files, and what to name them (internal issue 626). * Add src/spec/indexExt.py to autogenerate registry index entries linking into the 1.0-extensions specification, instead of maintaining the index manually. (internal issue 642). * Autogenerate extension dependencies and lists of all extensions and all KHR extensions from the "supported" attributes in +vk.xml+. Execute +make config/extDependency.sh+ from +doc/specs/vulkan+ when a supported extension is added to vk.xml, to regenerate the dependency script. The consequence is that specifying a single extension to the +makeExt+ script will automatically enable all extensions it depends on as well, and that the +makeAllExts+ and +makeKHR+ scripts do not need to be updated when a new extension is supported (internal issue 648). * Put extension appendices all at the same asciidoc section level, so KHR WSI extensions show up in the HTML index (internal issue 648). Other Issues: * Imbed images in the generated HTML specs instead of loading them from the images/ directory. * Fix missing EXT in extension name (ename:VK_EXT_SWAPCHAIN_COLOR_SPACE_EXTENSION_NAME). * Add new +VK_EXT_SMPTE_2086_metadata+ extension. * In the <<platformCreateSurface_xlib,Xlib Surface>> section of the +VK_KHR_xlib_surface+ specification, add language warning users that they always need to call code:XinitThreads. * Use the term "presentable image" (rather than "swapchain image") consistently in +VK_KHR_swapchain+ and related extensions, and add a glossary term defining it. * Relocate the valid usage for samples of flink:vkGetPhysicalDeviceSparseImageFormatProperties2KHR::pname:pFormatInfo to be below the flink:VkPhysicalDeviceSparseImageFormatInfo2KHR structure.

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Change log for June 24, 2016 Vulkan 1.0.18 spec update: * Bump API patch number and header version number to 18 for this update. Github Issues: * Added "queue operation" terminology, and modified spec to actually use this terminology (public issue 155). The act of submitting a piece of work to a queue now generates "operations" for the queue to execute, including operations to wait on/signal semaphores and fences. Synchronization waits on these operations, making execution dependency chains more obvious for semaphores and fences (though additional work is still needed here). These changes include: ** Overview of "queue submission" commands in chapter <<devsandqueues-submission>>. ** Updated descriptions for fence and semaphore waits and signals in the synchronization chapter <<synchronization-semaphores-waiting>>, <<synchronization-semaphores-signaling>> and <<synchronization-fences-waiting>>. ** Clarifications to semaphore and fence operation within queue submission functions. ** New glossary terms. ** Moved device idle and queue wait idle to synchronization chapter in order to describe them in terms of other synchronization primitives. ** Clarifications to semaphore and fence operation allowed removal of the "implicit ordering guarantees" section, as this information is now wholly covered where these primitives are described. *** The "host writes" section of this is still there for now - in its own section. This could probably be merged into other sections later. *** Modified fundamentals chapter on queue ordering to make sense in context of the new changes, and avoid duplication. <<fundamentals-queueoperation>> * Added "aspect" and "component" definitions to the glossary, and made sure these terms are referenced correctly (public issue 163). * Update valid usage for ftext:vkGet*ProcAddr to only include conditions that must be met to get a valid result. In particular, it's okay to call flink:vkGetDeviceProcAddr with any string and will get a code:NULL if that string is not a core Vulkan function or an enabled extension function (addresses but does not fully close public issue 214). * Change the WSI extension dependencies to refer to version 1.0 of the Vulkan API, instead of the pre-1.0-release internal revisions numbers (public issue 238). * Specified that <<interfaces-fragmentoutput,undeclared fragment shader outputs>> result in undefined values input to the blending unit or color attachment (public issue 240). Internal Issues: * Better documented that the registry XML "optional" tag for values only applies when that value is the size of an array (internal issue 335). * Add a stronger definition for the valid usages of VkSpecializationMapEntry.size in the <<pipelines-specialization-constants,Specialization Constants>> section (internal issue 345). * Change code:OpName to code:OpDecorate (along with appropriate syntax) for vertex shader built-ins (internal issue 368). * Add missing ref pages (those which are not currently stubs) to apispec.txt for the single-page version of the ref pages (internal issue 378). Other Commits: * Fix example in the <<descriptorsets,Descriptor Sets>> section to use M, N, and I, describing set, binding, and index, consistently throughout the example code.

Internal Issues: * Better documented that the registry XML "optional" tag for values only applies when that value is the size of an array (internal issue 335). * Add a stronger definition for the valid usages of VkSpecializationMapEntry.size in the <<pipelines-specialization-constants,Specialization Constants>> section (internal issue 345). * Change code:OpName to code:OpDecorate (along with appropriate syntax) for vertex shader built-ins (internal issue 368). * Add missing ref pages (those which are not currently stubs) to apispec.txt for the single-page version of the ref pages (internal issue 378). Other Commits: * Fix example in the <<descriptorsets,Descriptor Sets>> section to use M, N, and I, describing set, binding, and index, consistently throughout the example code.

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for November 25, 2016 Vulkan 1.0.35 spec update: * Bump API patch number and header version number to 35 for this update. Github Issues: * Document in the <<memory-device-hostaccess,Host Access>> section that mapping and unmapping does not invalidate or flush the mapped memory (public issues 27, 126). * Redefine the entire <<synchronization>> chapter in terms of consistent and well defined terminology, that's called out at the start of the chapter. This terminology is applied equally to all synchronization types, including subpass dependencies, submissions, and much of the implicit ordering stuff dotted around the spec. Key terms are laid out in the <<synchronization-dependencies,Execution and Memory Dependencies>> section at the top of the rewritten chapter (public issues 128, 131, 132, 217, 299, 300, 302, 306, 322, 346, 347, 371, 407). * Specify order of submission for batches in the <<vkQueueSubmit,vkQueueSubmit>> and <<vkQueueBindSparse,vkQueueBindSparse>> commands (public issue 371). * Add valid usage statements to each of the WSI extension sections indicating that the WSI-specific structure parameters must be valid, and remove automatically generated valid usage statements now covered by the manual sections (public issue 383). * Clarify render pass compatibility for flink:vkCmdExecuteCommands (public issue 390). Internal Issues: * Update +vk.xml+ to make previously explicit valid usage statements for <<vkDebugReportMessageEXT,vkDebugReportMessageEXT>> implicit instead (internal issue 553). * Add valid usage statement for slink:VkCreateImageInfo preventing creation of 1D sparse images (internal issue 573). * Fix Python scripts to always read/write files in utf-8 encoding, and a logic error in reflib.py which could cause a fatal error for malstructured asciidoc (internal issues 578, 586).

Change log for December 1, 2016 Vulkan 1.0.36 spec update: * Bump API patch number and header version number to 36 for this update. Github Issues: * Fix "recorded with" terminology in the valid usage language for the flink:vkCmdExecuteCommands::pname:pCommandBuffers parameter (public issue 390). * Modify +genvk.py+ to support specifying extensions to remove from output generators, allowing the extension loader +vulkan_ext.c+ to be created without WSI extensions which are statically exported by the Vulkan loader (public issue 412). * Added validation language for slink:VkSubpassDependency and in the <<synchronization-access-types-supported,supported access types>> section to catch access masks that include bits which are not supported by pipeline stages in the stage masks (partially addresses public issue 1006). Internal Issues: * Added validation language for flink:vkCmdWaitEvents, flink:vkQueueSubmit, flink:VkRenderPassCreateInfo, and in the <<synchronization-pipeline-stages-supported>> section to prevent recording stage dependencies that aren't supported on the queue (internal issue 516). * Make a few changes that generalize spec language for use with possible future extensions by adding glossary terms and generalizing ``feature'' to ``feature or extension'' where relevant (internal issues 448, 590). * Added "pipeline type" attribute to +vk.xml+ for relevant commands and utilize it in automatic generation of the Command Properties table (internal issue 517). * Specify that WSI implementations must provide both UNORM and sRGB formats in the description of slink:VkColorSpaceKHR (internal issue 529). * Remove nesting of explicit valid usage statements where it is not meaningful (internal issue 583). Other Issues: * Add validity language requiring that slink:VkPushConstantRange::pname:offset be a multiple of 4, as stated in the spec language.

Change log for January 23, 2017 Vulkan 1.0.39 spec update: * Bump API patch number and header version number to 39 for this update. Github Issues: * Clarified that only accesses via the specified buffer/image subresource ranges are included in the access scopes (public issue 306). * Add missing valid usage statements for flink:vkCreateComputePipelines and flink:vkCreateGraphicsPipelines (public issue 427). Internal Issues: * Add a Note to the <<invariance,Invariance>> appendix about a difference between OpenGL and Vulkan with regards to how primitives derived from offsets are handled (internal issue 355). * Add the +<<VK_KHR_get_physical_device_properties2>>+, +<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+ extensions (internal issue 448). * Add the +<<VK_EXT_shader_subgroup_vote>>+ and +<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449). * Update the texture level-of-detail equation in the <<textures-scale-factor,Scale Factor Operation>> section to better approximate the ellipse major and minor axes (internal issue 547). * Forbid non-explicitly allowed uses of interface decorations in the introduction to the <<interfaces,Shader Interfaces>> chapter (internal issue 607). * Replace use of MathJax with KaTeX, for improved load-time performance as well as avoiding the scrolling-and-scrolling behavior due to MathJax asynchronous rendering when loading at an anchor inside the spec. This change also requires moving to HTML5 output for the spec instead of XHTML, and there is a visible difference in that the chapter navigation index is now in a scrollable sidebar instead of at the top of the document. We may or may not retain the nav sidebar based on feedback (internal issue 613). * Improve consistency of markup and formatting in extension appendices (internal issue 631). Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage. If the swapchain has been replaced, then it should not be passed to flink:vkAcquireNextImage. * Add a valid usage statement to flink:vkCreateImageView, that the image must have been created with an appropriate usage bit set. * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section. * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor to account for the multiple viewport feature. If the feature is not enabled, the parameters for these functions have required values that are defined in the <<features-features-multiViewport,multiple viewports>> section of the spec but were not reflected in the valid usage text for these functions. * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common color spaces.

Internal Issues: * Change slink:VkMappedMemoryRange valid usage to allow pname:offset + pname:size == size of the allocation. Also, if ename:VK_WHOLE_SIZE is used, require the end of the mapping to be aligned to a multiple of pname:nonCoherentAtomSize (internal issue 611). * Add issue to `VK_KHR_win32_surface` about reusing window objects from a different graphics API or Vulkan ICD (internal issue 639). * Require locations on user in/out in `GL_KHR_vulkan_glsl` (internal issue 783). * Added version info to the json validation output, and updated the schema to match (internal issue 838). * Restructure enumerated type descriptions separately from the command or structure they are used in, allowing better reference page generation (internal issue 841). * Re-sort extension appendices to be in alphabetical order within each author ID section. * Fix enum naming and clarify behavior for `VK_NVX_device_generated_commands` extension.

Internal Issues: * Make <<textures-output-format-conversion, computation of derivatives in non-uniform flow control>> have undefined behavior (internal issue 1367). * Make behavior, not just values, undefined for <<textures-layout-validation, reads from inconsistent YCbCr layouts>> (internal issue 1366). * Consolidate version and extension behavior documentation in the <<extended-functionality, Extended Functionality>> appendix, While a great deal of text was moved from other parts of the Specification into the appendix, this just serves to simplify and make consistent discussions of versions and extensions (internal issue 1473). * Add limits for slink:VkPhysicalDeviceRayTracingPropertiesNV in the <<features-limits-types, Required Limit Types>> and <<features-limits-required, Required Limits>> tables (internal issue 1511). * Disallow <<memory-protected-memory, indirect calls within protected command buffers>> by adding valid usage statements for the related indirect dispatch and draw commands (internal issue 1513). * Add valid usage stataements to slink:VkGraphicsPipelineCreateInfo, slink:VkSubpassDescription, slink:VkSubpassDescription2KHR, slink:VkSubpassDescriptionDepthStencilResolveKHR, and slink:VkImageViewCreateInfo preventing the creation of a renderpass with attachments in formats that are not supported for rendering (internal issue 1552). * Qualify valid usage statements for slink:VkAttachmentReference::pname:layout parameter so restrictions only apply if an attachment is ename:VK_ATTACHMENT_UNUSED (internal issue 1561). * Add valid usage statement for flink:vkCmdDrawIndirectByteCountEXT restricting pname:vertexStride to be positive (internal issue 1566). * Make the `VK_EXT_sample_locations` extension depend on `VK_KHR_get_physical_device_properties2` in `vk.xml`. * Rearrange and simplify the <<interfaces-resources-layout, block layout rules>>.

Github Issues: * Refer to standard sparse image block shape format tables explicitly in the <<sparsememory-standard-shapes, Standard Sparse Image Block Shapes>> section (public issue 93). * Add the missing definition of the code:LocalInvocationIndex decoration in the <<interfaces-builtin-variables, Built-In Variables>> section (public issue 532). * Clarify dynamic state definition in the introduction to the <<pipelines, Pipelines>> section and the new <<pipelines-dynamic-state, Dynamic State>> subsection (public issue 620). * Clarified deprecation statement in the `VK_AMD_negative_viewport_height` appendix (public issue 674). * Fix parameter descriptions for flink:vkCreateIndirectCommandsLayoutNVX (public issue 677). Internal Issues: * Remove description of <<primsrast-points, rasterization point size>> being taken from the tessellation control shader, since there are no circumstances under which you can have TCS without TES (internal issue 522). * Define <<copies-images-format-size-compatibility, _size-compatible_ image formats>> for flink:vkCmdCopyImage, add it to the glossary, and use that definition for slink:VkImageViewCreateInfo (internal issue 771). * Change brief descriptions of enumerant names, and of parameters which are enumerants, from "`enum *indicates*`" to "`enum *specifies*`" for consistency, and add a markup style guide rule (internal issue 862). * Clarify how execution dependencies interact with <<synchronization-submission-order, submission order>> at numerous places in the <<renderpass, Render Pass>> and <<synchronization, Synchronization>> chapters (internal issue 1062). * Clarify statement in the <<interfaces-resources-setandbinding, DescriptorSet and Binding Assignment>> section that only interface variables statically used by the entry point used in a pipeline must be present in the descriptor set layout (internal issue 1172). * Flip sparse image diagrams with partially full mip levels vertically, to match graph origins of other image diagrams (internal issue 1176). * Update new SVG diagrams to have consistent style and base font size, increase consistency of primitive topology diagrams, and add a section to the style guide on creating and editing images in a consistent style (internal issue 1177). * Resolve problems with valid usage statement extraction by fixing existing VUID tags for interfaces promoted to version 1.1 and fixing conditional directives around VUID-VkMemoryDedicatedAllocateInfo-image-01797 (internal issue 1184). * Strip `KHR` suffixes from a few interfaces promoted to Vulkan 1.1 that were missed previously (internal issue 1185). * Restrict code:OpImageQuerySizeLod and code:OpImageQueryLevels to only work on code:Image operands with their code:Sampled operand set to 1. In other words, these operations are not defined to work with storage images (internal issue 1193). * Recycle extension slot for extension #82 in `vk.xml`. This extension was never published (internal issue 1195). * Add an issue to the `VK_KHR_maintenance1` appendix noting that zero height viewports are allowed when this extension is enabled (internal issue 1202). * Fix slink:VkDescriptorSetLayoutBinding description so that shader stages always use descriptor bindings, not the other way around (internal issue 1206). * Fix field name for slink:VkInputAttachmentAspectReference::pname:inputAttachmentIndex (internal issue 1210). Other Issues: * Fix a few broken links in the <<versions-1.1, Version 1.1>> appendix. * Replace a few old refBegin/refEnd tags with open block markup around interfaces, and remove old KHX VUID tags that were breaking the valid usage statement extraction. * Fix error codes accidentally tagged as success codes in `vk.xml` for flink:vkGetSwapchainCounterEXT. * Added valid usage statements for ftext:vkBind*Memory2 input structures stext:VkBind*MemoryInfo, and fix a pname:image -> pname:buffer typo in a couple of places. * Fix swapped descriptions of elink:VkDescriptorType enums ename:VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE and ename:VK_DESCRIPTOR_TYPE_STORAGE_IMAGE (reported via tweet). New Extensions: * `VK_ANDROID_external_memory_android_hardware_buffer`

Change log for October 6, 2017 Vulkan 1.0.62 spec update: * Bump API patch number and header version number to 62 for this update. Github Issues: * Move asciidoc conditionals for `VK_KHR_maintenance1` in slink:VkDescriptorSetAllocateInfo so valid usage statements for `VK_KHR_push_descriptor` aren't accidentally removed when the first extension isn't enabled (public issue 573). * Fixed errors in API example code for flink:vkUpdateDescriptorSetWithTemplateKHR and flink:vkCmdPushDescriptorSetWithTemplateKHR (public issue 577). Internal Issues: * Specify constraints on concurrent access to fences that share payload in the <<synchronization-fences-importing, Importing Fence Payloads>> and <<synchronization-semaphores-waiting-state, Semaphore State Requirements For Wait Operations>> sections (internal issue 820). * Define the term "`retired swapchain`", reorganize some swapchain language, and improve language for pname:oldSwapchain in flink:VkSwapchainCreateInfoKHR, the <<swapchain-wsi-image-create-info>> table, flink:vkDestroySwapchainKHR, and flink:vkAcquireNextImage2KHX (internal issue 869). * Describe in the <<writing-arrays, Describing Properties of Array Elements>> section of the style guide how and when to use "`each`" and "`any`" to refer to properties of array elements, and make those uses in the specification consistent (internal issue 884). * Clarified that events cannot be used for cross-queue synchronization in the <<synchronization-events, Events>> section and for flink:vkCmdWaitEvents (internal issue 970). * Add success and error codes to +vk.xml+ for flink:vkCreateValidationCacheEXT (internal issue 995). * Clarify aspect mask usage for image memory barriers of multi-plane images in slink:VkImageSubresourceRange, slink:VkImageMemoryBarrier, and the <<textures-layout-validation, Layout Validation>> section (internal issue 996). Other Issues: * Fixed typo in flink:VkRenderPassSampleLocationsBeginInfoEXT (renamed field pname:pSubpassSampleLocations to pname:pPostSubpassSampleLocations). * Add missing buffer usage requirements for indirect draws in flink:vkCmdDrawIndirect, flink:vkCmdDrawIndirectCountAMD, flink:vkCmdDrawIndexedIndirect, and flink:vlCmdDrawIndexedIndirectCountAMD. * Modify Makefile to allow specification to build in git "`detached HEAD`" state. * Update valid usage ID generation script to allow recursively operating on all `.txt` files in a specified directory, and move the `startVUID` tracking information into a separate python file that is automatically updated by the script. New Extensions: * Add +vk.xml+ entries for pending `VK_ANDROID_native_buffer` extension (note, this extension is not yet enabled). * `VK_AMD_shader_image_load_store_lod`

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for January 23, 2017 Vulkan 1.0.39 spec update: * Bump API patch number and header version number to 39 for this update. Github Issues: * Clarified that only accesses via the specified buffer/image subresource ranges are included in the access scopes (public issue 306). * Add missing valid usage statements for flink:vkCreateComputePipelines and flink:vkCreateGraphicsPipelines (public issue 427). Internal Issues: * Add a Note to the <<invariance,Invariance>> appendix about a difference between OpenGL and Vulkan with regards to how primitives derived from offsets are handled (internal issue 355). * Add the +<<VK_KHR_get_physical_device_properties2>>+, +<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+ extensions (internal issue 448). * Add the +<<VK_EXT_shader_subgroup_vote>>+ and +<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449). * Update the texture level-of-detail equation in the <<textures-scale-factor,Scale Factor Operation>> section to better approximate the ellipse major and minor axes (internal issue 547). * Forbid non-explicitly allowed uses of interface decorations in the introduction to the <<interfaces,Shader Interfaces>> chapter (internal issue 607). * Replace use of MathJax with KaTeX, for improved load-time performance as well as avoiding the scrolling-and-scrolling behavior due to MathJax asynchronous rendering when loading at an anchor inside the spec. This change also requires moving to HTML5 output for the spec instead of XHTML, and there is a visible difference in that the chapter navigation index is now in a scrollable sidebar instead of at the top of the document. We may or may not retain the nav sidebar based on feedback (internal issue 613). * Improve consistency of markup and formatting in extension appendices (internal issue 631). Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage. If the swapchain has been replaced, then it should not be passed to flink:vkAcquireNextImage. * Add a valid usage statement to flink:vkCreateImageView, that the image must have been created with an appropriate usage bit set. * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section. * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor to account for the multiple viewport feature. If the feature is not enabled, the parameters for these functions have required values that are defined in the <<features-features-multiViewport,multiple viewports>> section of the spec but were not reflected in the valid usage text for these functions. * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common color spaces.

Change log for September 6, 2016 Vulkan 1.0.26 spec update: * Bump API patch number and header version number to 26 for this update. Github Issues: * Bring sample code in the +VK_KHR_surface+ and +VK_KHR_swapchain+ extension summary appendices up to date, and note they will be replaced with pointers to the LunarG SDK examples in the future (public issue 279). * Add a new <<fundamentals-commandsyntax-results-lifetime,Lifetime of Retrieved Results>> section specifying that ftext:vkGet* and ftext:VkEnumerate* results are invariant unless otherwise specified, and specify behavior for individual commands which are not invariant (public issue 280). * Remove conflicting definition of slink:VkDisplayPlaneCapabilitiesKHR::pname:maxSrcPosition and clean up language of the remaining definition (public issue 351). * Fix many minor spelling errors and add rules to the style guide to prevent recurrences (public issue 352). Internal Issues: * Remove redundant descriptions of the etext:VK_USE_PLATFORM_* macros from the <<wsi,Window System Integration>> chapter in favor of the description in the <<boilerplate-wsi-header,Window System-Specific Header Control>> appendix (internal issue 6). * Replace misleading 'can: be destroyed when not X' with more correct 'must: not be destroyed while X' in the <<fundamentals-objectmodel-lifetime,Object Lifetime>> section. Disallow destroying a pipeline layout while a command buffer using it is recording (internal issue 241). * Clarify that ename:VK_IMAGE_USAGE_TRANSIENT_ATTACHMENT_BIT is valid for all images used as attachments in elink:VkImageUsageFlagBits and the slink:VkImageLayout validity language (internal issue 320). * Note that <<extended-functionality-layers,Layers>> may wrap object handles, but that this is a generally discouraged. A link to additional information in the documentation for layer authors is provided (issue 398) * Replace the mustnot: and shouldnot: macros with equivalent must: not and should: not to get rid of non-English words while still highlighting normative language (internal issue 407). * Disallow creating multisampled images with ename:VK_IMAGE_CREATE_CUBE_COMPATIBLE_BIT in the slink:VkImageLayout validity language and the <<features-supported-sample-counts,Supported Sample Counts>> section (internal issue 445). * Fix typo so that flink:vkCmdDrawIndexedIndirect is defined in terms of flink:vkCmdDrawIndexed rather than flink:vkCmdDrawIndirect (internal issue 446). * Reorganize the per-extension information sections to all be in the <<extensions,Layers & Extensions>> appendix. Also fix a typo in +VK_IMG_filter_cubic+ which incorrectly identified it as a +KHR+ extension (internal issue 461). Other Issues: * Use asciidoc markup instead of latexmath to simplify diagrams in the <<features-formats-non-packed,byte mapping tables>> for color formats. * Fix a markup problem with the wildcarded enumerant names in a NOTE in the <<textures-texel-replacement,Texel Replacement>> section. * Fix missing attributes in the XML interface for elink:VkExternalMemoryHandleTypeFlagBitsNV and elink:VkExternalMemoryFeatureFlagBitsNV (KhronosGroup/Vulkan-Hpp issue #25) * Cleanup reference page builds so only core pages are built for releases.

Change log for September 30, 2016 Vulkan 1.0.29 spec update: * Bump API patch number and header version number to 29 for this update. Github Issues: * Remove redundant constraint on slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue 224). * Fix typo and remove link in Note in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section (public issue 359). * Fix erroneous validation statement for the pname:layout member of slink:VkComputePipelineCreateInfo (public issue 362). Internal Issues: * Restore long figure captions using asciidoc sidebar blocks, due to restrictions of asciidoc syntax (internal issue 101). * Replace most latexmath equations with comparable markup in straight asciidoc, which significantly improves time required to fully load and process the HTML forms of the Specification. There are known minor font and alignment inconsistencies with MathJax and PDF rendering of latexmath equations. Please do not file github issues about these. We are aware of the inconsistencies and will make refinements over time, while the performance improvements are compelling in at least some major browsers (internal issue 313). * Move handcoded validity statements from +vk.xml+ into the Specification body, easing work in the single-branch model. Specify the distinction between these explicit statements, and the implicit validity statements inferred from vk.xml. Validity statements now appear in two blocks for each command and structure - handcoded "Valid Usage" and the implicit "Valid Usage (Implicit)" (internal issue 392). * Add the +returnedonly="false"+ attribute to WSI output structures, removing incorrectly generated implicit validity statements for slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR, slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR, slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures (internal issue 486). * Update slink:VkImageLayout to require the ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images (internal issue 487). * Use an explicit format specifier string for the date command invocation in the +Makefile+ instead of the shorthand -R option, which doesn't work on BSD and MaxOS X date commands (internal issue 500). Other Issues: * Use the terms ``allocation scope'' and ``extension scope'' instead of just ``scope'', and add them to the glossary.

Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for January 23, 2017 Vulkan 1.0.39 spec update: * Bump API patch number and header version number to 39 for this update. Github Issues: * Clarified that only accesses via the specified buffer/image subresource ranges are included in the access scopes (public issue 306). * Add missing valid usage statements for flink:vkCreateComputePipelines and flink:vkCreateGraphicsPipelines (public issue 427). Internal Issues: * Add a Note to the <<invariance,Invariance>> appendix about a difference between OpenGL and Vulkan with regards to how primitives derived from offsets are handled (internal issue 355). * Add the +<<VK_KHR_get_physical_device_properties2>>+, +<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+ extensions (internal issue 448). * Add the +<<VK_EXT_shader_subgroup_vote>>+ and +<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449). * Update the texture level-of-detail equation in the <<textures-scale-factor,Scale Factor Operation>> section to better approximate the ellipse major and minor axes (internal issue 547). * Forbid non-explicitly allowed uses of interface decorations in the introduction to the <<interfaces,Shader Interfaces>> chapter (internal issue 607). * Replace use of MathJax with KaTeX, for improved load-time performance as well as avoiding the scrolling-and-scrolling behavior due to MathJax asynchronous rendering when loading at an anchor inside the spec. This change also requires moving to HTML5 output for the spec instead of XHTML, and there is a visible difference in that the chapter navigation index is now in a scrollable sidebar instead of at the top of the document. We may or may not retain the nav sidebar based on feedback (internal issue 613). * Improve consistency of markup and formatting in extension appendices (internal issue 631). Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage. If the swapchain has been replaced, then it should not be passed to flink:vkAcquireNextImage. * Add a valid usage statement to flink:vkCreateImageView, that the image must have been created with an appropriate usage bit set. * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section. * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor to account for the multiple viewport feature. If the feature is not enabled, the parameters for these functions have required values that are defined in the <<features-features-multiViewport,multiple viewports>> section of the spec but were not reflected in the valid usage text for these functions. * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common color spaces.

Change log for May 12, 2017 Vulkan 1.0.49 spec update: * Bump API patch number and header version number to 49 for this update. Github Issues: * Modify reference page extraction script to make internal links to spec anchors refer to the core specification instead of being dangling links (public issue 455). * Fix GL_KHR_vulkan_glsl typo and add a nor-normative mapping to the newly published StorageBuffer class (public issue 466). * Both flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties return ename:VK_ERROR_LAYER_NOT_PRESENT, which covers the error case of an application providing a layer name that wasn't returned by ftext:vkEnumerate{Instance|Device}LayerProperties (public issue 487). * The specification for flink:VkApplicationInfo::apiVersion says that the driver must return ename:VK_ERROR_INCOMPATIBLE_DRIVER in the case that pname:apiVersion specifies a non-supported version. That means that the valid usage should not also state that, and so the VU statement is removed. The VU had language about "`an effective substitute`" that would have been lost, and so it was moved to the pname:apiVersion description (public issue 488). Internal Issues: * Modify implicit validity generator script to assign asciidoc anchors to all valid usage statements it generates, and reflow.py script to insert Valid Usage ID (VUID) tags into the specification source files for explicit valid usage statements. This has no semantic effects on the specification, but will support the validation layer's detection of valid usage violations and allow it to link into the corresponding part of the specification (internal issue 583). * Assign VUID tags to all explicit VU statements and document the process and tag format in the style guide (internal issue 583). * Clarify the rules of whether to structure new functionality as instance extensions, device extensions, or both in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section (internal issue 749). * Require that SPIR-V run-time arrays are only used with the code:BufferBlock decoration (internal issue 750). * Fix implicit and explicit valid usage statements for slink:VkWriteDescriptorSet::pname:dstSet (internal issue 767) * Fix SPIR-V code sample for ename:VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER in the <<descriptorsets-uniformtexelbuffer, Uniform Texel Buffer>> section (internal issue 770). * Clarify that disabling depth testing also disables depth writes in the <<fragops-ds-state, Depth and Stencil Operations>> section (internal issue 775). * flink:VkDescriptorImageInfo::pname:imageLayout must match the actual imageLayout at the time the image is accessed. This was in the spec text, but needed an associated valid usage statement. * Note that only 32-bit atomic operations are supported in the <<spirvenv-module-validation, Validation Rules within a Module>> section. * Note that code:UniformConstant variables must not have initializers in the <<spirvenv-module-validation, Validation Rules within a Module>> section. * Add a new elink:VkObjectType enumeration to the core API, promoted from elink:VkDebugObjectTypeEXT, since it is used for much more than just the debug_report extension.

Internal Issues: * Change slink:VkMappedMemoryRange valid usage to allow pname:offset + pname:size == size of the allocation. Also, if ename:VK_WHOLE_SIZE is used, require the end of the mapping to be aligned to a multiple of pname:nonCoherentAtomSize (internal issue 611). * Add issue to `VK_KHR_win32_surface` about reusing window objects from a different graphics API or Vulkan ICD (internal issue 639). * Require locations on user in/out in `GL_KHR_vulkan_glsl` (internal issue 783). * Added version info to the json validation output, and updated the schema to match (internal issue 838). * Restructure enumerated type descriptions separately from the command or structure they are used in, allowing better reference page generation (internal issue 841). * Re-sort extension appendices to be in alphabetical order within each author ID section. * Fix enum naming and clarify behavior for `VK_NVX_device_generated_commands` extension.

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Internal Issues: * Add the <<fundamentals-abi,Application Binary Interface>> section describing platform ABI requirements and recommendations, add examples of function and function pointer declarations to the <<boilerplate-platform-specific-calling-conventions, Platform-Specific Calling Conventions>> section, and remove related language that existed elsewhere in the specification (internal issue 64). * Describe where to document valid usage interactions of chained structures in the style guide, and fix one case now appearing in slink:VkBufferCreateInfo instead of the child slink:VkDedicatedAllocationBufferCreateInfoNV structure (internal issue 715). * Add example to the style guide of describing enumerated types which are empty when the spec is built without relevant extensions enabled, and apply it to existing examples for elink:VkDescriptorSetLayoutCreateFlagBits and elink:VkSubpassDescriptionFlagBits (internal issue 864). * Add a note to the <<fundamentals-validusage-enums, Valid Usage for Enumerated Types>> section that the special values suffixed with etext:_BEGIN_RANGE, etext:_END_RANGE, etext:_RANGE_SIZE and etext:_MAX_ENUM are not part of the API and should: not be used by applications (internal issue 872). * Added note to flink:vkCmdUpdateBuffers explaining the performance penalty for copies done in this way, and why the upper copy limit is what it is (internal issue 952). * Update `VK_KHX_device_group` to split some functionality into the new `VK_KHR_bind_memory2` extension, and rename that functionality (internal issue 969). * Remove *Status* fields from extension appendices, since they are by definition published and complete by the time they reach the public github repository (internal issue 973). Other Issues: * Update Data Format specification dependency to version 1.2 and change references to DF sections accordingly. * Update XML to make the pname:pAllocator parameter of flink:vkRegisterDeviceEventEXT and flink:vkRegisterDisplayEventEXT in the `VK_EXT_display_control` extension as optional.

Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

When a compressed image format and an uncompressed image format are
size-compatible, it means that the texel block size of the uncompressed
format must: equal the texel block size of the compressed format.

A sparse block in a sparse partially-resident image.
In addition to the sparse block size in bytes, sparse image blocks have
a corresponding width, height, and depth that define the dimensions of
these elements in units of texels or compressed texel blocks, the latter
being used in case of sparse images having a block-compressed format.

This caused renaming of sname:VkColorSpaceKHR and sname:VkPresentModeKHR etext:BEGIN_RANGE (etc.) tokens, but those tokens are metadata, not part of the API, and the Vulkan WG is OK with this change. This change adds ranges to two additional enums that were missing them due to not defining the "expand" attribute (internal issue 217). * Tweak makefile to generate ref page nroff (.3) files in the right output directory, working around an a2x limitation (internal issue 223). Other Commits: * Add validity requirements for flink:vkCmdCopyQueryPoolResults pname:dstBuffer parameter. * Fix ref page build to generate .3 targets in the right output directory.

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Change log for January 23, 2017 Vulkan 1.0.39 spec update: * Bump API patch number and header version number to 39 for this update. Github Issues: * Clarified that only accesses via the specified buffer/image subresource ranges are included in the access scopes (public issue 306). * Add missing valid usage statements for flink:vkCreateComputePipelines and flink:vkCreateGraphicsPipelines (public issue 427). Internal Issues: * Add a Note to the <<invariance,Invariance>> appendix about a difference between OpenGL and Vulkan with regards to how primitives derived from offsets are handled (internal issue 355). * Add the +<<VK_KHR_get_physical_device_properties2>>+, +<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+ extensions (internal issue 448). * Add the +<<VK_EXT_shader_subgroup_vote>>+ and +<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449). * Update the texture level-of-detail equation in the <<textures-scale-factor,Scale Factor Operation>> section to better approximate the ellipse major and minor axes (internal issue 547). * Forbid non-explicitly allowed uses of interface decorations in the introduction to the <<interfaces,Shader Interfaces>> chapter (internal issue 607). * Replace use of MathJax with KaTeX, for improved load-time performance as well as avoiding the scrolling-and-scrolling behavior due to MathJax asynchronous rendering when loading at an anchor inside the spec. This change also requires moving to HTML5 output for the spec instead of XHTML, and there is a visible difference in that the chapter navigation index is now in a scrollable sidebar instead of at the top of the document. We may or may not retain the nav sidebar based on feedback (internal issue 613). * Improve consistency of markup and formatting in extension appendices (internal issue 631). Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage. If the swapchain has been replaced, then it should not be passed to flink:vkAcquireNextImage. * Add a valid usage statement to flink:vkCreateImageView, that the image must have been created with an appropriate usage bit set. * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section. * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor to account for the multiple viewport feature. If the feature is not enabled, the parameters for these functions have required values that are defined in the <<features-features-multiViewport,multiple viewports>> section of the spec but were not reflected in the valid usage text for these functions. * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common color spaces.

Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Other Issues: * Add explicit valid usage statements to slink:VkImageCopy requiring that the source and destination layer ranges be contained in their respective source and destination images. * Add valid usage language for swapchain of flink:vkAcquireNextImage. If the swapchain has been replaced, then it should not be passed to flink:vkAcquireNextImage. * Add a valid usage statement to flink:vkCreateImageView, that the image must have been created with an appropriate usage bit set. * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section. * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor to account for the multiple viewport feature. If the feature is not enabled, the parameters for these functions have required values that are defined in the <<features-features-multiViewport,multiple viewports>> section of the spec but were not reflected in the valid usage text for these functions. * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common color spaces.

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future.

Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Change log for October 13, 2018 Vulkan 1.1.88 spec update: * Update release number to 88. Public Issues: * Make clear that tname:PFN_vkDebugUtilsMessengerCallbackEXT::pname:messageTypes is a bitmask, and correct a typo in the spelling of slink:VkDebugUtilsMessengerCreateInfoEXT.txt::pname:messageType (public pull request 800). * Make an ABI-compatible change of the type of slink:VkPhysicalDeviceDriverPropertiesKHR::pname:driverID to use the new elink:VkDriverIdKHR type (public issue 811). Internal Issues: * Clarify for the <<features-features-shaderStorageImageExtendedFormats>> feature and in the <<spirvenv-capabilities-table>> that the feature means that all of the formats are supported, and that otherwise the features can be queried per-format (internal issue 1273). * Clarified interactions of `VK_EXT_external_memory_host` with host cache management commands and structures flink:vkMapMemory, flink:vkFlushMappedMemoryRanges, slink:VkMappedMemoryRange, and flink:vkUnmapMemory using the new glossary term "`Host Mapped Device Memory`" (internal issue 1385). * Update the language for flink:vkCreateViSurfaceNN.txt describing the pname:currentExtent of a VI surface to more accurately reflect current capabilities, replacing "`undefined`" with more explicit behavior (internal issue 1410).

Change log for November 12, 2018 Vulkan 1.1.92 spec update: * Update release number to 92. Public Issues: * Move and modify valid usage statements dealing with pname:aspectMask in flink:vkCmdClearColorImage, flink:vkCmdClearDepthStencilImage, and slink:VkClearAttachment, so they are in places where all necessary information is available (public issue 529). * Fix math markup in <<textures-texel-anisotropic-filtering, Texel Anisotropic Filtering>> (public pull request 840). * Fix misspellings (public pull request 845).

Change log for September 5, 2017 Vulkan 1.0.60 spec update: * Bump API patch number and header version number to 60 for this update. Github Issues: * Document that <<queries-timestamps, Timestamp Queries>> can only be meaningfully compared when they are written from the same queue (public issue 216). * Document that the `<extension>` tag `type` attribute is required for non-disabled extensions (derived from, but does not close public issue 354). * Clean up registry schema length attribute descriptions to be consistent and correct (public issue 555). Internal Issues: * Replace as much of the hand-written extension appendix metadata as possible with asciidoc includes generated from corresponding attributes of +vk.xml+, and enhance the style guide to match. This avoids inconsistencies between +vk.xml+ and the appendices, and produces a more uniform style (internal issue 137). * Remove the generated extDependency.{py,sh} files from the tree and create them dynamically on demand instead, reducing merge conflicts (internal issue 713). * Add a prototype tool for generating in-place difference markup for sections guarded by asciidoc conditionals, and new syntax for open blocks to support it (internal issue 833). * Remove unnecessary restriction of etext:*SYNC_FD_BIT_KHR external handle types to the same physical device in the slink:VkPhysicalDeviceIDPropertiesKHR, flink:VkImportMemoryWin32HandleInfoKHR, slink:VkImportFenceWin32HandleInfoKHR, slink:VkImportFenceFdInfoKHR, slink:VkImportSemaphoreWin32HandleInfoKHR, slink:VkImportSemaphoreFdInfoKHR <<external-memory-handle-types-compatibility, External memory handle types compatibility>>, <<external-semaphore-handle-types-compatibility, External semaphore handle types compatibility>>, and <<external-fence-handle-types-compatibility, External fence handle types compatibility>> sections (internal issue 956). Other Issues: * Remove dependency of +VK_KHX_device_group+ on +VK_KHR_swapchain+ (there is an interaction, but not a strict dependency), and add a new `extension` attribute to the `<require` XML tag to allow classifying a subset of interfaces of an extension as requiring another extension.

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Github Issues: * Changed asciidoctor macros so cross-page links in the standalone reference pages function properly (public issue 462). Internal Issues: * Clarified host visibility discussion for slink:VkMemoryType, flink:vkInvalidateMappedMemoryRanges, elink:VkAccessFlagBits, and the <<synchronization-framebuffer-regions,Framebuffer Region Dependencies>> section, removing duplicated information and adding a central definition in the access types section (internal issue 552). * Change description of slink:vkGetPhysicalDeviceSurfacePresentModesKHR::pname:pPresentModes to return an array of values, not structures (internal issue 699).

Change log for November 25, 2016 Vulkan 1.0.35 spec update: * Bump API patch number and header version number to 35 for this update. Github Issues: * Document in the <<memory-device-hostaccess,Host Access>> section that mapping and unmapping does not invalidate or flush the mapped memory (public issues 27, 126). * Redefine the entire <<synchronization>> chapter in terms of consistent and well defined terminology, that's called out at the start of the chapter. This terminology is applied equally to all synchronization types, including subpass dependencies, submissions, and much of the implicit ordering stuff dotted around the spec. Key terms are laid out in the <<synchronization-dependencies,Execution and Memory Dependencies>> section at the top of the rewritten chapter (public issues 128, 131, 132, 217, 299, 300, 302, 306, 322, 346, 347, 371, 407). * Specify order of submission for batches in the <<vkQueueSubmit,vkQueueSubmit>> and <<vkQueueBindSparse,vkQueueBindSparse>> commands (public issue 371). * Add valid usage statements to each of the WSI extension sections indicating that the WSI-specific structure parameters must be valid, and remove automatically generated valid usage statements now covered by the manual sections (public issue 383). * Clarify render pass compatibility for flink:vkCmdExecuteCommands (public issue 390). Internal Issues: * Update +vk.xml+ to make previously explicit valid usage statements for <<vkDebugReportMessageEXT,vkDebugReportMessageEXT>> implicit instead (internal issue 553). * Add valid usage statement for slink:VkCreateImageInfo preventing creation of 1D sparse images (internal issue 573). * Fix Python scripts to always read/write files in utf-8 encoding, and a logic error in reflib.py which could cause a fatal error for malstructured asciidoc (internal issues 578, 586).

Change log for December 1, 2016 Vulkan 1.0.36 spec update: * Bump API patch number and header version number to 36 for this update. Github Issues: * Fix "recorded with" terminology in the valid usage language for the flink:vkCmdExecuteCommands::pname:pCommandBuffers parameter (public issue 390). * Modify +genvk.py+ to support specifying extensions to remove from output generators, allowing the extension loader +vulkan_ext.c+ to be created without WSI extensions which are statically exported by the Vulkan loader (public issue 412). * Added validation language for slink:VkSubpassDependency and in the <<synchronization-access-types-supported,supported access types>> section to catch access masks that include bits which are not supported by pipeline stages in the stage masks (partially addresses public issue 1006). Internal Issues: * Added validation language for flink:vkCmdWaitEvents, flink:vkQueueSubmit, flink:VkRenderPassCreateInfo, and in the <<synchronization-pipeline-stages-supported>> section to prevent recording stage dependencies that aren't supported on the queue (internal issue 516). * Make a few changes that generalize spec language for use with possible future extensions by adding glossary terms and generalizing ``feature'' to ``feature or extension'' where relevant (internal issues 448, 590). * Added "pipeline type" attribute to +vk.xml+ for relevant commands and utilize it in automatic generation of the Command Properties table (internal issue 517). * Specify that WSI implementations must provide both UNORM and sRGB formats in the description of slink:VkColorSpaceKHR (internal issue 529). * Remove nesting of explicit valid usage statements where it is not meaningful (internal issue 583). Other Issues: * Add validity language requiring that slink:VkPushConstantRange::pname:offset be a multiple of 4, as stated in the spec language.

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Prefixes are used in the API to denote specific semantic meaning of Vulkan
names, or as a label to avoid name clashes, and are explained here:
2016-02-16 09:53:44 +00:00
VK/Vk/vk::
Vulkan namespace +
All types, commands, enumerants and defines in this specification are
prefixed with these two characters.
PFN/pfn::
Function Pointer +
Denotes that a type is a function pointer, or that a variable is of a
pointer type.
p::
Pointer +
Variable is a pointer.
vkCmd::
Commands that record commands in command buffers +
These API commands do not result in immediate processing on the device.
Instead, they record the requested action in a command buffer for
execution when the command buffer is submitted to a queue.
s::
Structure +
Used to denote the etext:VK_STRUCTURE_TYPE* member of each structure in
pname:sType
