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 July 10, 2016 Vulkan 1.0.20 spec update: * Bump API patch number and header version number to 20 for this update. Github Issues: * Replaced existing reference pages by text automatically extracted from the specification source, or generated from vk.xml in some cases. This isn't a complete solution for the reference pages, but puts them in a much better state. The ref pages (only) are now placed under a CC BY open source license, which is more current than the obsolete license previously used. Further improvements to the pages should not edit them directly, but instead concentrate on the specification source from which the ref pages are being extracted (public issues 44, 55, 160; internal issue 389).

Change log for July 22, 2016 Vulkan 1.0.22 spec update: * Bump API patch number and header version number to 22 for this update. Github Issues: * Translate the subpass self-dependency language into concrete validity statements, and added a validity statement about the restrictions on layout parameters (public issue 267). * Add validity requirement that slink:VkAttachmentDescription::pname:finalLayout and slink:VkAttachmentReference::pname:layout must not be ename:VK_IMAGE_LAYOUT_UNDEFINED or ename:VK_IMAGE_LAYOUT_PREINITIALIZED (public issue 268). * Clarify that slink:VkSubpassDescription::pname:pResolveAttachments layouts are used. Make language consistent with other attachment arrays (public issue 270). * Changed 64-bit definition for dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE to work for x32 platform in +vk.xml+ and the resulting +vulkan.h+ (public issue 282). * Add missing error return code for flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties (public issue 285) * Fix several cases of stext::VkStructName.memberName markup to stext::VkStructName::pname:memberName, to match other usage in the spec, and describe this markup in the style guide (public issue 286). * Modified validity language generation script to avoid redundant common ancestor language if covered by generic parent language, and used `Both' instead of `Each' when appropriate (public issue 288). Internal Issues: * Add language about behavior of flink:vkAllocateDescriptorSets when allocation fails due to fragmentation, a new error ename:VK_ERROR_FRAGMENTED_POOL, and a Note explaining the situation (internal issue 309). * For the features of code:PointSize, code:ClipDistance, and code:CullDistance, the SPIR-V capability is required to be declared on use (read or write) rather than on decoration (internal issue 359). * Have desktop versions of GLSL respect precision qualification (code:mediump and code:lowp) when compiling for Vulkan. These will get translated to SPIR-V's code:RelaxedPrecision decoration as they do with OpenGL ES versions of GLSL (ESSL). The default precision of all types is code:highp when using a desktop version (internal issue 360). * Add validity statement for slink:VkImageCreateInfo specifying that multisampled images must be two-dimensional, optimally tiled, and with a single mipmap level (internal issue 369). * Add validity statements to slink:VkImageViewCreateInfo disallowing creation of images or image views with no supported features. Made some slink:VkImageViewCreateInfo validity statements more precise and consistent. Added a Note to the <<features,features>> chapter about formats with no features (internal issue 371). * Remove +manpages+ from default build targets. Nroff outputs containing imbedded latexmath will not render properly. Fixing this is a lot of work for limited use cases (internal issue 401). Other Commits: * Fix flink:vkRenderPassBeginInfo::pname:clearValueCount validity statement to be based on attachment indices rather than the number of cleared attachments (Vulkan-LoaderAndValidationLayers/issues/601). * Convert registry documentation from LaTeX to asciidoc source and rename from +src/spec/readme.tex+ to +src/spec/registry.txt+. * Fix lack of Oxford commas in validity language. * Lots of cleanup of generator scripts and Makefiles to move extension list for generator into the script arguments instead of the body of genvk.py, and express better dependencies between XML, scripts, and generated files.

Change log for July 10, 2016 Vulkan 1.0.20 spec update: * Bump API patch number and header version number to 20 for this update. Github Issues: * Replaced existing reference pages by text automatically extracted from the specification source, or generated from vk.xml in some cases. This isn't a complete solution for the reference pages, but puts them in a much better state. The ref pages (only) are now placed under a CC BY open source license, which is more current than the obsolete license previously used. Further improvements to the pages should not edit them directly, but instead concentrate on the specification source from which the ref pages are being extracted (public issues 44, 55, 160; internal issue 389).

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 July 22, 2016 Vulkan 1.0.22 spec update: * Bump API patch number and header version number to 22 for this update. Github Issues: * Translate the subpass self-dependency language into concrete validity statements, and added a validity statement about the restrictions on layout parameters (public issue 267). * Add validity requirement that slink:VkAttachmentDescription::pname:finalLayout and slink:VkAttachmentReference::pname:layout must not be ename:VK_IMAGE_LAYOUT_UNDEFINED or ename:VK_IMAGE_LAYOUT_PREINITIALIZED (public issue 268). * Clarify that slink:VkSubpassDescription::pname:pResolveAttachments layouts are used. Make language consistent with other attachment arrays (public issue 270). * Changed 64-bit definition for dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE to work for x32 platform in +vk.xml+ and the resulting +vulkan.h+ (public issue 282). * Add missing error return code for flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties (public issue 285) * Fix several cases of stext::VkStructName.memberName markup to stext::VkStructName::pname:memberName, to match other usage in the spec, and describe this markup in the style guide (public issue 286). * Modified validity language generation script to avoid redundant common ancestor language if covered by generic parent language, and used `Both' instead of `Each' when appropriate (public issue 288). Internal Issues: * Add language about behavior of flink:vkAllocateDescriptorSets when allocation fails due to fragmentation, a new error ename:VK_ERROR_FRAGMENTED_POOL, and a Note explaining the situation (internal issue 309). * For the features of code:PointSize, code:ClipDistance, and code:CullDistance, the SPIR-V capability is required to be declared on use (read or write) rather than on decoration (internal issue 359). * Have desktop versions of GLSL respect precision qualification (code:mediump and code:lowp) when compiling for Vulkan. These will get translated to SPIR-V's code:RelaxedPrecision decoration as they do with OpenGL ES versions of GLSL (ESSL). The default precision of all types is code:highp when using a desktop version (internal issue 360). * Add validity statement for slink:VkImageCreateInfo specifying that multisampled images must be two-dimensional, optimally tiled, and with a single mipmap level (internal issue 369). * Add validity statements to slink:VkImageViewCreateInfo disallowing creation of images or image views with no supported features. Made some slink:VkImageViewCreateInfo validity statements more precise and consistent. Added a Note to the <<features,features>> chapter about formats with no features (internal issue 371). * Remove +manpages+ from default build targets. Nroff outputs containing imbedded latexmath will not render properly. Fixing this is a lot of work for limited use cases (internal issue 401). Other Commits: * Fix flink:vkRenderPassBeginInfo::pname:clearValueCount validity statement to be based on attachment indices rather than the number of cleared attachments (Vulkan-LoaderAndValidationLayers/issues/601). * Convert registry documentation from LaTeX to asciidoc source and rename from +src/spec/readme.tex+ to +src/spec/registry.txt+. * Fix lack of Oxford commas in validity language. * Lots of cleanup of generator scripts and Makefiles to move extension list for generator into the script arguments instead of the body of genvk.py, and express better dependencies between XML, scripts, and generated files.

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.

pname:magFilter to always be used.
This is valid, just not an exact match for OpenGL behavior.
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.

Clamping the maximum LOD to 0.25 allows the [eq]#{lambda}# value to be
non-zero and minification to be performed, while still always rounding down
to the base level.

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.

Change log for September 15, 2017 Vulkan 1.0.61 spec update: * Bump API patch number and header version number to 61 for this update. 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`

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`

Internal Issues: * Update flink:vkAllocateDescriptorSets to specify conditions under which to return ename:VK_ERROR_FRAGMENTED_POOL or ename:VK_ERROR_OUT_OF_POOL_MEMORY instead of out-of-host/out-of-device-memory, and improve the <<fundamentals-errorcodes, description of those errors (internal issue 654). * Add a NOTE documenting that flink:vkAcquireNextImageKHR can only signal a single semaphore, and how to deal with that when multiple physical devices in a logical device need to wait on it (internal issue 730). * Improve description of pname:pNext chains of slink:VkPhysicalDeviceImageFormatInfo2KHR and slink:VkImageFormatProperties2KHR (internal issue 814). * Clean up math markup issues in the <<textures, Image Operations>> chapter (internal issue 818). * Update validusage target to use more robust code for preprocessing, by making direct use of Asciidoctor's preprocessor. Added uniqueItems check to JSON vu schema and add clean_validusage target (internal issue 826). * Update style guide to prohibit writing non-self-contained (on a single bullet point) Valid Usage statements, and modify offending Valid Usage statements in the Specification to match, to assist with automatic extraction for the validation layers (internal issue 828). * Add ename:VK_VALIDATION_CHECK_SHADERS_EXT to elink:VkValidationCheckEXT of the `VK_EXT_validation_flags` extension, to selectively disable shader validation. * Remove duplicate valid usage statement for slink:VkImageMemoryBarrier. * Modify reflow.py script to place VUID tag anchors standalone on a line following their corresponding bullet point, and reflow the spec text accordingly (this had been pending since the initial tag deployment). New Extensions: * `VK_AMD_texture_gather_bias_lod`

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.

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 May 20, 2017 Vulkan 1.0.50 spec update: * Bump API patch number and header version number to 50 for this update. Github Issues: * Fix numerous minor issues with the VK_EXT_debug_report extension (public issues 478, 483, 486, 489, 490). Internal Issues: * Update flink:vkAllocateDescriptorSets to specify conditions under which to return ename:VK_ERROR_FRAGMENTED_POOL or ename:VK_ERROR_OUT_OF_POOL_MEMORY instead of out-of-host/out-of-device-memory, and improve the <<fundamentals-errorcodes, description of those errors (internal issue 654). * Add a NOTE documenting that flink:vkAcquireNextImageKHR can only signal a single semaphore, and how to deal with that when multiple physical devices in a logical device need to wait on it (internal issue 730). * Improve description of pname:pNext chains of slink:VkPhysicalDeviceImageFormatInfo2KHR and slink:VkImageFormatProperties2KHR (internal issue 814). * Clean up math markup issues in the <<textures, Image Operations>> chapter (internal issue 818). * Update validusage target to use more robust code for preprocessing, by making direct use of Asciidoctor's preprocessor. Added uniqueItems check to JSON vu schema and add clean_validusage target (internal issue 826). * Update style guide to prohibit writing non-self-contained (on a single bullet point) Valid Usage statements, and modify offending Valid Usage statements in the Specification to match, to assist with automatic extraction for the validation layers (internal issue 828). * Add ename:VK_VALIDATION_CHECK_SHADERS_EXT to elink:VkValidationCheckEXT of the `VK_EXT_validation_flags` extension, to selectively disable shader validation. * Remove duplicate valid usage statement for slink:VkImageMemoryBarrier. * Modify reflow.py script to place VUID tag anchors standalone on a line following their corresponding bullet point, and reflow the spec text accordingly (this had been pending since the initial tag deployment). New Extensions: * `VK_AMD_texture_gather_bias_lod`

Replace 'pNext list' with 'pNext chain'. Fixed typo in the example code of +VK_KHR_dedicated_allocation+ (internal issue 944). * Fix typo in elink:VkExternalSemaphoreHandleTypeFlagBitsKHR enum descriptions, replacing etext:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_FENCE_FD_BIT_KHR with ename:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SYNC_FD_BIT_KHR, and make the description more consistent with VK_EXTERNAL_FENCE_HANDLE_TYPE_SYNC_FD_BIT_KHR (internal issue 950).

Change log for July 10, 2016 Vulkan 1.0.20 spec update: * Bump API patch number and header version number to 20 for this update. Github Issues: * Replaced existing reference pages by text automatically extracted from the specification source, or generated from vk.xml in some cases. This isn't a complete solution for the reference pages, but puts them in a much better state. The ref pages (only) are now placed under a CC BY open source license, which is more current than the obsolete license previously used. Further improvements to the pages should not edit them directly, but instead concentrate on the specification source from which the ref pages are being extracted (public issues 44, 55, 160; internal issue 389).

Change log for July 22, 2016 Vulkan 1.0.22 spec update: * Bump API patch number and header version number to 22 for this update. Github Issues: * Translate the subpass self-dependency language into concrete validity statements, and added a validity statement about the restrictions on layout parameters (public issue 267). * Add validity requirement that slink:VkAttachmentDescription::pname:finalLayout and slink:VkAttachmentReference::pname:layout must not be ename:VK_IMAGE_LAYOUT_UNDEFINED or ename:VK_IMAGE_LAYOUT_PREINITIALIZED (public issue 268). * Clarify that slink:VkSubpassDescription::pname:pResolveAttachments layouts are used. Make language consistent with other attachment arrays (public issue 270). * Changed 64-bit definition for dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE to work for x32 platform in +vk.xml+ and the resulting +vulkan.h+ (public issue 282). * Add missing error return code for flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties (public issue 285) * Fix several cases of stext::VkStructName.memberName markup to stext::VkStructName::pname:memberName, to match other usage in the spec, and describe this markup in the style guide (public issue 286). * Modified validity language generation script to avoid redundant common ancestor language if covered by generic parent language, and used `Both' instead of `Each' when appropriate (public issue 288). Internal Issues: * Add language about behavior of flink:vkAllocateDescriptorSets when allocation fails due to fragmentation, a new error ename:VK_ERROR_FRAGMENTED_POOL, and a Note explaining the situation (internal issue 309). * For the features of code:PointSize, code:ClipDistance, and code:CullDistance, the SPIR-V capability is required to be declared on use (read or write) rather than on decoration (internal issue 359). * Have desktop versions of GLSL respect precision qualification (code:mediump and code:lowp) when compiling for Vulkan. These will get translated to SPIR-V's code:RelaxedPrecision decoration as they do with OpenGL ES versions of GLSL (ESSL). The default precision of all types is code:highp when using a desktop version (internal issue 360). * Add validity statement for slink:VkImageCreateInfo specifying that multisampled images must be two-dimensional, optimally tiled, and with a single mipmap level (internal issue 369). * Add validity statements to slink:VkImageViewCreateInfo disallowing creation of images or image views with no supported features. Made some slink:VkImageViewCreateInfo validity statements more precise and consistent. Added a Note to the <<features,features>> chapter about formats with no features (internal issue 371). * Remove +manpages+ from default build targets. Nroff outputs containing imbedded latexmath will not render properly. Fixing this is a lot of work for limited use cases (internal issue 401). Other Commits: * Fix flink:vkRenderPassBeginInfo::pname:clearValueCount validity statement to be based on attachment indices rather than the number of cleared attachments (Vulkan-LoaderAndValidationLayers/issues/601). * Convert registry documentation from LaTeX to asciidoc source and rename from +src/spec/readme.tex+ to +src/spec/registry.txt+. * Fix lack of Oxford commas in validity language. * Lots of cleanup of generator scripts and Makefiles to move extension list for generator into the script arguments instead of the body of genvk.py, and express better dependencies between XML, scripts, and generated files.

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 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.

To create a sampler with Y'C~B~C~R~ conversion enabled, add a
slink:VkSamplerYcbcrConversionInfoKHR to the pname:pNext chain of the
slink:VkSamplerCreateInfo structure.
To create a sampler Y'C~B~C~R~ conversion, the
<<features-features-sampler-YCbCr-conversion,pname:samplerYcbcrConversion

Conversion must: be fixed at pipeline creation time, through use of a
combined image sampler with an immutable sampler in
sname:VkDescriptorSetLayoutBinding.
A slink:VkSamplerYcbcrConversionInfoKHR must: be provided for samplers to be
used with image views that access ename:VK_IMAGE_ASPECT_COLOR_BIT if the
format appears in <<features-formats-requiring-sampler-ycbcr-conversion>>.
The sname:VkSamplerYcbcrConversionInfoKHR structure is defined as:

****
include::../validity/structs/VkSamplerYcbcrConversionCreateInfoKHR.txt[]
If pname:chromaFilter is ename:VK_FILTER_NEAREST, chroma samples are
reconstructed to luma channel resolution using nearest-neighbour sampling.
Otherwise, chroma samples are reconstructed using interpolation.
More details can be found in <<textures-sampler-YCbCr-conversion,the
description of sampler Y'C~B~C~R~ conversion>> in the <<textures,Image
Operations>> chapter.

elink:VkSamplerYcbcrModelConversionKHR defines the conversion from the
source color model to the shader color model.
Possible values are:
include::../api/enums/VkSamplerYcbcrModelConversionKHR.txt[]
* ename:VK_SAMPLER_YCBCR_MODEL_CONVERSION_RGB_IDENTITY_KHR specifies that
the input values to the conversion are unmodified.
* ename:VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_IDENTITY_KHR specifies no
model conversion but the inputs are range expanded as for Y'C~B~C~R~.
* ename:VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_709_KHR specifies the
color model conversion from Y'C~B~C~R~ to R'G'B' defined in BT.709 and
described in the "`BT.709 Y’C~B~C~R~ conversion`" section of the
<<data-format,Khronos Data Format Specification>>.
* ename:VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_601_KHR specifies the
color model conversion from Y'C~B~C~R~ to R'G'B' defined in BT.601 and
described in the "`BT.601 Y’C~B~C~R~ conversion`" section of the
<<data-format,Khronos Data Format Specification>>.
* ename:VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_2020_KHR specifies the
color model conversion from Y'C~B~C~R~ to R'G'B' defined in BT.2020 and
described in the "`BT.2020 Y’C~B~C~R~ conversion`" section of the
<<data-format,Khronos Data Format Specification>>.
In the etext:VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_*_KHR color models, for
the input to the sampler Y'C~B~C~R~ range expansion and model conversion:
* the Y (Y' luma) channel corresponds to the G channel of an RGB image.
* the CB (C~B~ or "`U`" blue color difference) channel corresponds to the
B channel of an RGB image.
* the CR (C~R~ or "`V`" red color difference) channel corresponds to the R
channel of an RGB image.
* the alpha channel, if present, is not modified by color model
conversion.
These rules reflect the mapping of channels after the channel swizzle
operation (controlled by
slink:VkSamplerYcbcrConversionCreateInfoKHR::pname:components).
[NOTE]
.Note
====
For example, an "YUVA" 32-bit format comprising four 8-bit channels can be
implemented as ename:VK_FORMAT_R8G8B8A8_UNORM with a component mapping:
* pname:components.a = ename:VK_COMPONENT_SWIZZLE_IDENTITY
* pname:components.r = ename:VK_COMPONENT_SWIZZLE_B
* pname:components.g = ename:VK_COMPONENT_SWIZZLE_R
* pname:components.b = ename:VK_COMPONENT_SWIZZLE_G

[open,refpage='VkSamplerYcbcrRangeKHR',desc='Range of encoded values in a color space',type='enums']
--
The elink:VkSamplerYcbcrRangeKHR enum describes whether color channels are
encoded using the full range of numerical values or whether values are
reserved for headroom and foot room.
elink:VkSamplerYcbcrRangeKHR is defined as:
include::../api/enums/VkSamplerYcbcrRangeKHR.txt[]
* ename:VK_SAMPLER_YCBCR_RANGE_ITU_FULL_KHR indicates that the full range
of the encoded values are valid and interpreted according to the ITU
"`full range`" quantization rules.
* ename:VK_SAMPLER_YCBCR_RANGE_ITU_NARROW_KHR indicates that headroom and
foot room are reserved in the numerical range of encoded values, and the
remaining values are expanded according to the ITU "`narrow range`"
quantization rules.
The formulae for these conversions is described in the
<<textures-sampler-YCbCr-conversion-rangeexpand,Sampler Y'C~B~C~R~ Range
Expansion>> section of the <<textures,Image Operations>> chapter.
No range modification takes place if pname:ycbcrModel is
ename:VK_SAMPLER_YCBCR_MODEL_CONVERSION_RGB_IDENTITY_KHR; the
pname:ycbcrRange field of sname:VkSamplerYcbcrConversionCreateInfoKHR is
ignored in this case.

The elink:VkChromaLocationKHR enum, which defines the location of
downsampled chroma channel samples relative to the luma samples, is defined
as:
include::../api/enums/VkChromaLocationKHR.txt[]
* ename:VK_CHROMA_LOCATION_COSITED_EVEN_KHR indicates that downsampled
chroma samples are aligned with luma samples with even coordinates.
* ename:VK_CHROMA_LOCATION_MIDPOINT_KHR indicates that downsampled chroma
samples are located half way between each even luma sample and the
nearest higher odd luma sample.
