Change log for January 5, 2018 Vulkan 1.0.67 spec update: * Bump API patch number and header version number to 67 for this update. * Update copyright dates to 2018 Github Issues: * Fix texture lookup functions in `GL_KHR_vulkan_glsl` specification (public pull request 363). * Clarify the state waited semaphores are left in when a call to flink:vkQueuePresentKHR fails (public issue 572). * Cleanup descriptions of slink:VkObjectTablePushConstantEntryNVX and slink:VkObjectTableDescriptorSetEntryNVX (public issue 583) * Remove redundant flink:vkCmdSetDiscardRectangleEXT valid usage statements (public pull 586). * Make dynamic state array length valid usage statements implicit for flink:vkCmdSetViewportWScalingNV, flink:vkCmdSetDiscardRectangleEXT, and flink:vkCmdSetViewport (public pull 589). * Clarify meaning of window extent (0,0) in slink:VkSwapchainKHR for the Windows and X11 platforms, in their respective extensions (public issue 590). * Allow flink:vkGetPastPresentationTimingGOOGLE to return ename:VK_INCOMPLETE (public issue 604). * Add synchronization valid usage statements to flink:vkAcquireNextImage (public pull 611). * Fix some broken external links and internal xrefs (public pull 613). * Clean up slink:VkViewport valid usage statements in the presence or absence of relevant extensions (public pull 623). * Remove ename:VK_IMAGE_LAYOUT_DEPTH_READ_ONLY_STENCIL_ATTACHMENT_OPTIMAL_KHR token from VK_KHR_maintenance2 from the non-extension VU path for slink:VkGraphicsPipelineCreateInfo (public issue 628). * Miscellaneous minor markup fixes - extension name strings (public pull 631), Notes (pull 633), queue names emitted by generator scripts (pull 634), block formatting in slink:VkDescriptorUpdateTemplateEntryKHR (pull 635), ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_CUBIC_BIT_IMG (pull 641), quotes and apostrophes (pull 643), * Miscellaneous minor grammar fixes (public pull 644). * Fix markup macros so usage like ptext:*Src* works (public pull 647). 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. New Extensions: * `VK_EXT_conservative_rasterization`

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 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.

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.

= Introduction
This document describes the Khronos Vulkan API Registry schema, and
provides some additional information about using the registry and
scripts to generate a variety of outputs, including C header files as
well as several types of asciidoc include files used in the Vulkan API
specification and reference pages. The underlying XML files and scripts
are located on the Khronos public Github server at URL
https://github.com/KhronosGroup/Vulkan-Docs
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`

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 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.

An XML schema and validator target are included.
The schema is based on, but not identical to that used for the previously
published OpenGL, OpenGL ES and EGL API registries. It was extended to
represent additional types and concepts not needed for those APIs, such as
structure and enumerant types, as well as additional types
of registered information specific to Vulkan.
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 5, 2018 Vulkan 1.1.72 spec update: * Update release number to 72. Github Issues: * Restructure the repository to put the specification `Makefile` and associated spec source material at the top level, `vk.xml` and associated scripts material in `xml/`, and generated include and source files in `include/vulkan/` and `src/ext_loader/`, respectively (public issue 436). * Add missing bullet point markup to flink:vkCmdCopyImage valid usage statement, so it gets a VUID assigned (public issue 627). * Fix broken links in a couple of extension appendices (public pull request 665). * Add the \<platform> tag to the index in section 4.1 of the registry schema documentation, and add the protect= attribute of \<extension> tags to the comments in `registry.rnc` (public issues 673, 678). * Add missing valid usage statements for sparse image interactions to flink:VkImageCreateInfo (public pull request 675). * Fix improper usage and grammar of "`can: not`" (public pull request 681). * Remove duplicate spec language and NOTE on present layout between the flink:vkAcquireNextImageKHR and flink:vkAcquireNextImage2KHR commands (public pull request 685). * Fix some typos and markup issues (public pull request 689; public issues 642, 667, 687). * Fix typo etext:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_FENCE_FD_BIT -> ename:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SYNC_FD_BIT in the <<external-semaphore-handle-types-compatibility, External semaphore handle types compatibility>> table (public pull request 691). Internal Issues: * Remove the need for the "`noautovalidity`" attribute on extension structures in `vk.xml`. It is now implied by the "`structextends`" attribute instead (internal issue 942). * Replace uses of "`currently bound`" with "`bound`", since "`currently`" is redundant and distracting, and add a corresponding rule to the style guide (internal issue 993). * Fixed subtle issues with the last updates to flink:vkAcquireNextImageKHR language that had resulted in ambiguities (internal issue 1178). * Make it clear that only one query of a given type is allowed at a time by reordering valid usage statements for flink:vkCmdBeginQuery and flink:vkCmdEndQuery, and removing redundant ones (internal issue 1213). * Swapped OL1 and OL3 in `tessparamUL.svg` to match previous version, and fixed where "`(no edge)`" appears (internal issue 1215). Other Issues: * Fixed a minor problem with the valid usage statement extraction script, and corresponding markup in the spec source. New Extensions: * `VK_AMD_shader_core_properties` * `VK_EXT_descriptor_indexing` * `VK_NV_shader_subgroup_partitioned`

Please tag your issues with `[Registry]` in the subject line to help us
categorize them. We have considered separating the registry from the
specification source into a separate repository, but since there is so
much specification valid usage language imbedded in the registry XML,
this is unlikely to happen.
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 March 5, 2018 Vulkan 1.1.72 spec update: * Update release number to 72. Github Issues: * Restructure the repository to put the specification `Makefile` and associated spec source material at the top level, `vk.xml` and associated scripts material in `xml/`, and generated include and source files in `include/vulkan/` and `src/ext_loader/`, respectively (public issue 436). * Add missing bullet point markup to flink:vkCmdCopyImage valid usage statement, so it gets a VUID assigned (public issue 627). * Fix broken links in a couple of extension appendices (public pull request 665). * Add the \<platform> tag to the index in section 4.1 of the registry schema documentation, and add the protect= attribute of \<extension> tags to the comments in `registry.rnc` (public issues 673, 678). * Add missing valid usage statements for sparse image interactions to flink:VkImageCreateInfo (public pull request 675). * Fix improper usage and grammar of "`can: not`" (public pull request 681). * Remove duplicate spec language and NOTE on present layout between the flink:vkAcquireNextImageKHR and flink:vkAcquireNextImage2KHR commands (public pull request 685). * Fix some typos and markup issues (public pull request 689; public issues 642, 667, 687). * Fix typo etext:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_FENCE_FD_BIT -> ename:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SYNC_FD_BIT in the <<external-semaphore-handle-types-compatibility, External semaphore handle types compatibility>> table (public pull request 691). Internal Issues: * Remove the need for the "`noautovalidity`" attribute on extension structures in `vk.xml`. It is now implied by the "`structextends`" attribute instead (internal issue 942). * Replace uses of "`currently bound`" with "`bound`", since "`currently`" is redundant and distracting, and add a corresponding rule to the style guide (internal issue 993). * Fixed subtle issues with the last updates to flink:vkAcquireNextImageKHR language that had resulted in ambiguities (internal issue 1178). * Make it clear that only one query of a given type is allowed at a time by reordering valid usage statements for flink:vkCmdBeginQuery and flink:vkCmdEndQuery, and removing redundant ones (internal issue 1213). * Swapped OL1 and OL3 in `tessparamUL.svg` to match previous version, and fixed where "`(no edge)`" appears (internal issue 1215). Other Issues: * Fixed a minor problem with the valid usage statement extraction script, and corresponding markup in the spec source. New Extensions: * `VK_AMD_shader_core_properties` * `VK_EXT_descriptor_indexing` * `VK_NV_shader_subgroup_partitioned`

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`
2018-03-07 12:18:52 +00:00

Change log for February 27, 2017 Vulkan 1.0.42 spec update: * Bump API patch number and header version number to 42 for this update (the first anniversary edition).

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 5, 2018 Vulkan 1.1.72 spec update: * Update release number to 72. Github Issues: * Restructure the repository to put the specification `Makefile` and associated spec source material at the top level, `vk.xml` and associated scripts material in `xml/`, and generated include and source files in `include/vulkan/` and `src/ext_loader/`, respectively (public issue 436). * Add missing bullet point markup to flink:vkCmdCopyImage valid usage statement, so it gets a VUID assigned (public issue 627). * Fix broken links in a couple of extension appendices (public pull request 665). * Add the \<platform> tag to the index in section 4.1 of the registry schema documentation, and add the protect= attribute of \<extension> tags to the comments in `registry.rnc` (public issues 673, 678). * Add missing valid usage statements for sparse image interactions to flink:VkImageCreateInfo (public pull request 675). * Fix improper usage and grammar of "`can: not`" (public pull request 681). * Remove duplicate spec language and NOTE on present layout between the flink:vkAcquireNextImageKHR and flink:vkAcquireNextImage2KHR commands (public pull request 685). * Fix some typos and markup issues (public pull request 689; public issues 642, 667, 687). * Fix typo etext:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_FENCE_FD_BIT -> ename:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SYNC_FD_BIT in the <<external-semaphore-handle-types-compatibility, External semaphore handle types compatibility>> table (public pull request 691). Internal Issues: * Remove the need for the "`noautovalidity`" attribute on extension structures in `vk.xml`. It is now implied by the "`structextends`" attribute instead (internal issue 942). * Replace uses of "`currently bound`" with "`bound`", since "`currently`" is redundant and distracting, and add a corresponding rule to the style guide (internal issue 993). * Fixed subtle issues with the last updates to flink:vkAcquireNextImageKHR language that had resulted in ambiguities (internal issue 1178). * Make it clear that only one query of a given type is allowed at a time by reordering valid usage statements for flink:vkCmdBeginQuery and flink:vkCmdEndQuery, and removing redundant ones (internal issue 1213). * Swapped OL1 and OL3 in `tessparamUL.svg` to match previous version, and fixed where "`(no edge)`" appears (internal issue 1215). Other Issues: * Fixed a minor problem with the valid usage statement extraction script, and corresponding markup in the spec source. New Extensions: * `VK_AMD_shader_core_properties` * `VK_EXT_descriptor_indexing` * `VK_NV_shader_subgroup_partitioned`

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 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 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.

See +doc/specs/vulkan/README.html+ and the ``Layers and Extensions'' section of the ``Vulkan Documentation and Extensions'' document for more information on this change. * Register and publish new extensions in the single-branch form: ** +VK_NV_external_memory_capabilities+ ** +VK_NV_external_memory+ ** +VK_NV_external_memory_win32+ ** +VK_NV_win32_keyed_mutex+ Github Issues: * Clarify description of GetInstanceProcAddr and GetDeviceProcAddr (public issue 212). * Add SPIR-V <<textures-operation-validation, instruction validation>> for single-sampled images (public issue 316). * Fix spelling of ``tesselation'' in a few places and note it as an exception to the American spelling rules convention (public issue 327). * Fix Makefile to create output directory for ``styleguide'' target (public issue 329). * Fix numerous minor issues with incorrectly tags on enumerant names and table titles (public issue 330). * Generate specversion.txt date in UTC time and RFC 2822 format (public issue 335). * Convert link to the SPIR-V Specification for flink:VkShaderModuleCreateInfo into an internal link to the normative reference (public issue 336). * Add ename:VK_ERROR_OUT_OF_MEMORY error code to flink:vkCreateDebugReportCallbackEXT (public issue 337). Internal Issues: * Update style guide regarding use of code:NULL and dname:VK_NULL_HANDLE (internal issue 393). * Change the definition of latexmath:[$q$] in the <<textures-image-level-selection,texture image level selection>> section to be the index of the maximum defined level for the view, not the number of levels in the view (internal issue 406). * Allow developers to override dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE with their own binary-compatible definition (internal issue 439). * Fix +vk_platform.h+ conditional logic causing compile failure with some Android compilers (internal issue 441). * Implement the single-branch model as described above (internal issue 461).

Additionally, specific API versions and extensions can be required or
excluded. Based on this information, the generator script extracts the
relevant interfaces and creates a C-language header file for them.
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 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).

The generator script is intended to be generalizable to other languages by
writing new generator classes. Such generators would have to rewrite the C
types and definitions in the XML to something appropriate to their language.
Change log for August 26, 2016 Vulkan 1.0.25 spec update: * Bump API patch number and header version number to 25 for this update. * Structurally change the specification so that multiple extensions are included in the +1.0+ git branch, and specifications will include or not include those extensions at build time based on options passed to the Makefile. See +doc/specs/vulkan/README.html+ and the ``Layers and Extensions'' section of the ``Vulkan Documentation and Extensions'' document for more information on this change. * Register and publish new extensions in the single-branch form: ** +VK_NV_external_memory_capabilities+ ** +VK_NV_external_memory+ ** +VK_NV_external_memory_win32+ ** +VK_NV_win32_keyed_mutex+ Github Issues: * Clarify description of GetInstanceProcAddr and GetDeviceProcAddr (public issue 212). * Add SPIR-V <<textures-operation-validation, instruction validation>> for single-sampled images (public issue 316). * Fix spelling of ``tesselation'' in a few places and note it as an exception to the American spelling rules convention (public issue 327). * Fix Makefile to create output directory for ``styleguide'' target (public issue 329). * Fix numerous minor issues with incorrectly tags on enumerant names and table titles (public issue 330). * Generate specversion.txt date in UTC time and RFC 2822 format (public issue 335). * Convert link to the SPIR-V Specification for flink:VkShaderModuleCreateInfo into an internal link to the normative reference (public issue 336). * Add ename:VK_ERROR_OUT_OF_MEMORY error code to flink:vkCreateDebugReportCallbackEXT (public issue 337).

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 August 26, 2016 Vulkan 1.0.25 spec update: * Bump API patch number and header version number to 25 for this update. * Structurally change the specification so that multiple extensions are included in the +1.0+ git branch, and specifications will include or not include those extensions at build time based on options passed to the Makefile. See +doc/specs/vulkan/README.html+ and the ``Layers and Extensions'' section of the ``Vulkan Documentation and Extensions'' document for more information on this change. * Register and publish new extensions in the single-branch form: ** +VK_NV_external_memory_capabilities+ ** +VK_NV_external_memory+ ** +VK_NV_external_memory_win32+ ** +VK_NV_win32_keyed_mutex+ Github Issues: * Clarify description of GetInstanceProcAddr and GetDeviceProcAddr (public issue 212). * Add SPIR-V <<textures-operation-validation, instruction validation>> for single-sampled images (public issue 316). * Fix spelling of ``tesselation'' in a few places and note it as an exception to the American spelling rules convention (public issue 327). * Fix Makefile to create output directory for ``styleguide'' target (public issue 329). * Fix numerous minor issues with incorrectly tags on enumerant names and table titles (public issue 330). * Generate specversion.txt date in UTC time and RFC 2822 format (public issue 335). * Convert link to the SPIR-V Specification for flink:VkShaderModuleCreateInfo into an internal link to the normative reference (public issue 336). * Add ename:VK_ERROR_OUT_OF_MEMORY error code to flink:vkCreateDebugReportCallbackEXT (public issue 337).

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 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.

Vulkan Specification.
Change log for March 5, 2018 Vulkan 1.1.72 spec update: * Update release number to 72. Github Issues: * Restructure the repository to put the specification `Makefile` and associated spec source material at the top level, `vk.xml` and associated scripts material in `xml/`, and generated include and source files in `include/vulkan/` and `src/ext_loader/`, respectively (public issue 436). * Add missing bullet point markup to flink:vkCmdCopyImage valid usage statement, so it gets a VUID assigned (public issue 627). * Fix broken links in a couple of extension appendices (public pull request 665). * Add the \<platform> tag to the index in section 4.1 of the registry schema documentation, and add the protect= attribute of \<extension> tags to the comments in `registry.rnc` (public issues 673, 678). * Add missing valid usage statements for sparse image interactions to flink:VkImageCreateInfo (public pull request 675). * Fix improper usage and grammar of "`can: not`" (public pull request 681). * Remove duplicate spec language and NOTE on present layout between the flink:vkAcquireNextImageKHR and flink:vkAcquireNextImage2KHR commands (public pull request 685). * Fix some typos and markup issues (public pull request 689; public issues 642, 667, 687). * Fix typo etext:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_FENCE_FD_BIT -> ename:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SYNC_FD_BIT in the <<external-semaphore-handle-types-compatibility, External semaphore handle types compatibility>> table (public pull request 691). Internal Issues: * Remove the need for the "`noautovalidity`" attribute on extension structures in `vk.xml`. It is now implied by the "`structextends`" attribute instead (internal issue 942). * Replace uses of "`currently bound`" with "`bound`", since "`currently`" is redundant and distracting, and add a corresponding rule to the style guide (internal issue 993). * Fixed subtle issues with the last updates to flink:vkAcquireNextImageKHR language that had resulted in ambiguities (internal issue 1178). * Make it clear that only one query of a given type is allowed at a time by reordering valid usage statements for flink:vkCmdBeginQuery and flink:vkCmdEndQuery, and removing redundant ones (internal issue 1213). * Swapped OL1 and OL3 in `tessparamUL.svg` to match previous version, and fixed where "`(no edge)`" appears (internal issue 1215). Other Issues: * Fixed a minor problem with the valid usage statement extraction script, and corresponding markup in the spec source. New Extensions: * `VK_AMD_shader_core_properties` * `VK_EXT_descriptor_indexing` * `VK_NV_shader_subgroup_partitioned`

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.

API.
* <<tag-commands,tag:commands>> - defines API commands
(functions). Usually only one tag is used.
* <<tag-feature,tag:feature>> - defines API feature interfaces
(API versions, more or less). One tag per feature set.
* <<tag-extensions,tag:extensions>> - defines API extension
interfaces. Usually only one tag is used, wrapping many extensions.
Change log for July 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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`

= Platform Names (tag:platform tag)
A tag:platform tag describes a single platform name.
== Attributes of tag:platform tags
* attr:name - required.
The platform name.
This must be a short alphanumeric string corresponding to the platform
name, valid as part of a C99 identifier.
Lower-case is preferred.
In some cases, it may be desirable to distinguish a subset of platform
functionality from the entire platform.
In these cases, the platform name should begin with the entire platform
name, followed by `_` and the subset name.

For example,
`name="xlib"`
is used for the X Window System, Xlib client library platform.
`name="xlib_xrandr"`
is used for the XRandR functionality within the `xlib` platform.
====

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 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

== Contents of tag:types tags
Zero or more tag:type and tag:comment tags, in arbitrary order (though they
are typically ordered by putting dependencies of other types earlier in the
list).
The tag:comment tags are used mostly to indicate grouping of related types.
[[tag-type]]
= API Type (tag:type tag)
A tag:type tag contains information which can be used to generate C code
corresponding to the type. In many cases, this is simply legal C code, with
attributes or embedded tags denoting the type name and other types used in
defining this type. In some cases, additional attribute and embedded type
information is used to generate more complicated C types.

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`
2018-03-07 12:18:52 +00:00
* attr:alias - optional. Another type name which this type is an alias of.
Must match the name of another tag:type element. This is typically used
when promoting a type defined by an extension to a new core version of
the API. The old extension type is still defined, but as an alias of the
new type.

the API, rather than an application filling it out and passing it to
the API.
Change log for July 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

* attr:structextends only applicable if category is `struct` or `union`.
This is a comma-separated list of structures whose `pNext` can include
this type.
This should usually only list the top-level structure that is
extended, for all possible chained structures - the chained structures
themselves should have their `pNext` tagged with attr:noautovalidity.
This will generate a validity statement on the top level structure
that validates the entire chain in one go, rather than each chained
structure repeating the list of valid structs.

Change log for July 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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.

* The tag:name tag is required, and contains the struct/union member
name being described.
Change log for July 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

* The tag:enum tag is optional. It contains text which is a valid
enumerant name found in another tag:type tag, and indicates that this
enumerant must be previously defined for the definition of the command
to succeed. Typically this is used to semantically tag static array
lengths.
* The tag:comment tag is optional. It contains an arbitrary string
(unused).

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.

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.

Change log for July 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

It would make more sense to call these `const` or `define` tags.

Change log for July 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

[[tag-enum]]
= Enumerants (tag:enum tag)
Each tag:enum tag defines a single Vulkan (or other API) token.
== Attributes of tag:enum tags
* attr:value or attr:bitpos - exactly one of these is allowed and
required. attr:value is an enumerant value in the form of a legal C
constant (usually a literal decimal or hexadecimal integer, though
arbitrary strings are allowed). attr:bitpos is a literal integer bit
position in a bitmask.
* attr:name - required. Enumerant name, a legal C preprocessor token
name.
* attr:api - optional. An API name which specializes this definition
of the named enum, so that different APIs may have different values
for the same token. May be used to address a subtle
incompatibilities.
* attr:type - optional. Used only when attr:value is specified. C
suffix for the value to force it to a specific type. Currently only

values, respectively. Separated from attr:value since this eases
parsing and sorting of values, and rarely used.
* attr:alias - optional. Name of another enumerant this is an alias
of, used where token names have been changed as a result of profile
changes or for consistency purposes. An enumerant alias is simply a
different attr:name for the exact same attr:value or attr:bitpos.

tag:enum tags have no allowed contents. All information is contained
in the attributes.
[[tag-unused]]
= Unused Enumerants (tag:unused tag)
Each tag:unused tag defines a range of enumerants which is allocated, but
not yet assigned to specific enums. This just tracks the unused values for
the Registrar's use, and is not used for header generation.

be a good way to avoid the attributes becoming out of date. However, they
are rarely used in the Vulkan XML schema, unlike the OpenGL XML schema it

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 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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`

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: * 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).

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`

The second way of defining a command is as an alias of another command. For
example when an extension is promoted from extension to core status, the
commands defined by that extensions become aliases of the corresponding new
core commands. In this case, only two attributes are allowed:
* attr:name - required. A string naming the command defined by the tag.
* attr:alias - required. A string naming the command that attr:name is an
alias of. The string must be the same as the attr:name value of another
tag:command defining another command.

== Contents of tag:command tags
* tag:proto is required and must be the first element. It is a tag
defining the C function prototype of a command as described below,
up to the function name and return type but not including function
parameters.
* tag:param elements for each command parameter follow, defining its
name and type, as described below. If a command takes no arguments,
it has no tag:param tags.
Following these elements, the remaining elements in a tag:command
tag are optional and may be in any order:
* tag:alias - optional. Has no attributes and contains a string which
is the name of another command this command is an alias of, used
when promoting a function from vendor to Khronos extension or
Khronos extension to core API status. A command alias describes the
case where there are two function names which resolve to the _same_
entry point in the underlying layer stack.
* tag:description - optional. Unused text.
* tag:implicitexternsyncparams - optional. Contains a list of tag:param
tags, each containing asciidoc source text describing an object which is
not a parameter of the command but is related to one, and which also
<<tag-command:param:attr,requires external synchronization>>. The text
is intended to be incorporated into the API specification.
[[tag-command:proto]]
== Command prototype (tag:proto tags)
The tag:proto tag defines the return type and name of a command.
=== Attributes of tag:proto tags
None.
// attr:group - group name, an arbitrary string.
//
// If the group name is defined, it may be interpreted as described in
// <<tag-group:meaning>>.
=== Contents of tag:proto tags
The text elements of a tag:proto tag, with all other tags removed, is
legal C code describing the return type and name of a command. In addition
to text, it may contain two semantic tags:
* The tag:type tag is optional, and contains text which is a valid
type name found in a tag:type tag. It indicates that this type must
be previously defined for the definition of the command to succeed.
Builtin C types, and any derived types which are expected to be
found in other header files, should not be wrapped in tag:type tags.
* The tag:name tag is required, and contains the command name being
described.
[[tag-command:param]]
== Command parameter (tag:param tags)
The tag:param tag defines the type and name of a parameter. Its contents
are very similar to the tag:member tag used to define struct and union
members.
[[tag-command:param:attr]]
=== Attributes of tag:param tags

=== Contents of tag:param tags
The text elements of a tag:param tag, with all other tags removed, is
legal C code describing the type and name of a function parameter. In
addition it may contain two semantic tags:
* The tag:type tag is optional, and contains text which is a valid
type name found in tag:type tag, and indicates that this type must
be previously defined for the definition of the command to succeed.
Builtin C types, and any derived types which are expected to be
found in other header files, should not be wrapped in tag:type tags.
* The tag:name tag is required, and contains the parameter name being
described.

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 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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.

* attr:protect - optional. An additional preprocessor token used to
protect a feature definition. Usually another feature or extension
attr:name. Rarely used, for odd circumstances where the definition
of a feature or extension requires another to be defined first.
* attr:comment - optional. Arbitrary string (unused).
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`

[NOTE]
.Note
====
The attr:name attribute used for Vulkan core versions, such as
`"VK_VERSION_1_0"`, is not an API construct.
It is used only as a preprocessor guard in the headers, and an asciidoctor
conditional in the specification sources.
The similar `"VK_API_VERSION_1_0"` symbols are part of the API and their
values are packed integers containing Vulkan core version numbers.

== Contents of tag:extensions tags
Each tag:extensions block contains zero or more tag:extension tags,
each describing an API extension, in arbitrary order (although they are
typically ordered by sorting on the extension name, to improve human
readability).
[[tag-extension]]
= API Extensions (tag:extension tag)
API extensions are described in individual tag:extension tags. An
extension is the set of interfaces defined by a particular API extension
Change log for February 27, 2017 Vulkan 1.0.42 spec update: * Bump API patch number and header version number to 42 for this update (the first anniversary edition). 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 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: * Update the style guide to describe how to write LaTeX math expressions in table cells (internal issue 908). * Define how framebuffer-local dependencies work between subpasses with the same or different numbers of samples, in the slink:VkSubpassDescription and <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> sections. This clarifies which samples in an input attachment you are allowed to access after a framebuffer-local dependency (internal issue 915). * Specify which storage classes can have an initializer in the <<spirvenv-module-validation, Validation Rules within a Module>> section (internal issue 1023). * Use "LOD" consistently for "level-of-detail", to eliminate spelling inconsistencies.

the corresponding tag:tag attribute just like attr:author.
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. Update the registry schema and documentation accordingly. New Extensions: * `VK_AMD_shader_fragment_mask` (and related `GL_AMD_shader_fragment_mask` GLSL extension) * `VK_EXT_sample_locations` * `VK_EXT_validation_cache`

Change log for August 26, 2016 Vulkan 1.0.25 spec update: * Bump API patch number and header version number to 25 for this update. * Structurally change the specification so that multiple extensions are included in the +1.0+ git branch, and specifications will include or not include those extensions at build time based on options passed to the Makefile. See +doc/specs/vulkan/README.html+ and the ``Layers and Extensions'' section of the ``Vulkan Documentation and Extensions'' document for more information on this change. * Register and publish new extensions in the single-branch form: ** +VK_NV_external_memory_capabilities+ ** +VK_NV_external_memory+ ** +VK_NV_external_memory_win32+ ** +VK_NV_win32_keyed_mutex+ Github Issues: * Clarify description of GetInstanceProcAddr and GetDeviceProcAddr (public issue 212). * Add SPIR-V <<textures-operation-validation, instruction validation>> for single-sampled images (public issue 316). * Fix spelling of ``tesselation'' in a few places and note it as an exception to the American spelling rules convention (public issue 327). * Fix Makefile to create output directory for ``styleguide'' target (public issue 329). * Fix numerous minor issues with incorrectly tags on enumerant names and table titles (public issue 330). * Generate specversion.txt date in UTC time and RFC 2822 format (public issue 335). * Convert link to the SPIR-V Specification for flink:VkShaderModuleCreateInfo into an internal link to the normative reference (public issue 336). * Add ename:VK_ERROR_OUT_OF_MEMORY error code to flink:vkCreateDebugReportCallbackEXT (public issue 337). Internal Issues: * Update style guide regarding use of code:NULL and dname:VK_NULL_HANDLE (internal issue 393). * Change the definition of latexmath:[$q$] in the <<textures-image-level-selection,texture image level selection>> section to be the index of the maximum defined level for the view, not the number of levels in the view (internal issue 406). * Allow developers to override dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE with their own binary-compatible definition (internal issue 439). * Fix +vk_platform.h+ conditional logic causing compile failure with some Android compilers (internal issue 441). * Implement the single-branch model as described above (internal issue 461). Other Issues:
2016-08-28 10:47:19 +00:00
* attr:requires - optional. Comma-separated list of extension names this
extension requires to be supported.
* attr:protect - optional. An additional preprocessor token used to
protect an extension definition. Usually another feature or
extension attr:name. Rarely used, for odd circumstances where the
definition of an extension requires another extension or a header
file to be defined first.
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 February 27, 2017 Vulkan 1.0.42 spec update: * Bump API patch number and header version number to 42 for this update (the first anniversary edition). 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 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. Update the registry schema and documentation accordingly. New Extensions: * `VK_AMD_shader_fragment_mask` (and related `GL_AMD_shader_fragment_mask` GLSL extension) * `VK_EXT_sample_locations` * `VK_EXT_validation_cache`

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 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).

====
The attr:requires attribute is used to specify other extensions that *must*
be enabled for an extension to be enabled.
In some cases, an extension may include functionality which is only defined
*if* another extension is enabled. Such functionality should be specified
within a tag:require, using the attr:extension attribute to specify that
extension.

Change log for July 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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.

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 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`

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`

== Attributes of tag:require tags
These attribues are allowed only for a tag:require tag.
* attr:extension - optional, and only for tag:require tags. String
containing an API extension name. Interfaces in the tag are only
required if the string matches the attr:name of an tag:extension tag,
and that extension is enabled.
* attr:feature - optional, and only for tag:require tags. String
containing an API feature name. Interfaces in the tag are only required
if the string matches the attr:name of a tag:feature tag, and that
feature is enabled.
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. Update the registry schema and documentation accordingly. New Extensions: * `VK_AMD_shader_fragment_mask` (and related `GL_AMD_shader_fragment_mask` GLSL extension) * `VK_EXT_sample_locations` * `VK_EXT_validation_cache`

[NOTE]
.Note
====
The attr:extension attribute currently does not affect output generators in
any way, and is simply metadata. This will be addressed as we better define
different types of dependencies between extensions.

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.

== Contents of tag:require and tag:remove tags
Zero or more of the following tags, in any order:
Change log for July 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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.

* attr:api - optional. An API name which specializes this definition of
the enumerant attr:name, so that different APIs may have different

There are two forms of tag:enum tags:
_Reference enums_ simply pull in the definition of an enumerant given in
a separate tag:enums block. Reference enums are the most common usage,
and no attributes other than attr:name and attr:comment are supported
for them.

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`

_Extension enums_ define the value of an enumerant inline in an tag:feature
or tag:extensions block. Typically these are used to add additional values
specified by an extension or core feature to an existing enumerated type.
There are a variety of attributes which are used to specify the value of the
enumerant, although not all combinations of attributes are either meaningful
or supported. Possible attributes are described first, followed by the
allowed combinations:
* attr:value and attr:type - define a constant value in the same fashion
as an tag:enum tag in an <<tag-enum,tag:enums>> block.
* attr:bitpos - define a constant bitmask value in the same fashion as an
<<tag-enum,tag:enum>> tag in an tag:enums block.
* attr:extends - the name of a separately defined enumerated type (e.g. a
tag:type tag with attr:category`="enum"`) to which the extension
enumerant is added. If not present, the enumerant is treated as a global
constant value.
* attr:extnumber - an extension number. The extension number in turn
specifies the starting value of a block (range) of values reserved for
enumerants defined by or associated with the corresponding tag:extension
tag with the same attr:number. This is used when an extension or core
feature needs to extend an enumerated type in a block defined by a
different extension.
* Attribute attr:offset - the offset within an extension block. If
attr:extnumber is not present, the extension number defining that block
is given by the attr:number attribute of the surrounding tag:extension
tag. The actual numeric value of the enumerant is computed as defined in
the "`Layers and Extensions`" appendix of the Vulkan Specification.
* Attribute attr:dir - if present, the calculated enumerant value will be
negative, instead of positive. Negative enumerant values are normally
used only for Vulkan error codes. The attribute value must be specified
as `dir="-"`.
* attr:alias - the name of another enumerant this is an alias of. An
enumerant alias is simply a different name for the same enumerant value.
This is typically used when promoting an enumerant defined by an
extension to a new core version of the API. The old extension enumerant
is still defined, but as an alias of the new core enumerant. It may also
be used when token names have been changed as a result of profile
changes, or for consistency purposes.
* attr:api - an API name which specializes this definition of the named
enum, so that different APIs may have different values for the same
token. May be used to address subtle incompatibilities.
.Valid Combinations of attr:enum Attributes
|====
| attr:value | attr:bitpos | attr:alias | attr:offset | attr:extnumber | attr:dir | attr:extends | Description
| {yes} | {no} | {no} | {no} | {no} | {no} | {opt}^2^ | Numeric value
| {no} | {yes} | {no} | {no} | {no} | {no} | {opt}^2^ | Bitmask value
| {no} | {no} | {yes} | {no} | {no} | {no} | {opt}^2^ | Alias of another enumerant
| {no} | {no} | {no} | {yes} | {opt}^1^ | {opt} | {yes} | Value added to an enumeration
| {no} | {no} | {no} | {yes} | {opt}^1^ | {opt} | {yes} | Value added to an enumeration
|====
[1]: If attr:extnumber is not present, the tag:enum tag may only be within a
tag:extension. Otherwise, the tag:enum tag may also be within a tag:feature.
[2]: If attr:extends is not present, the enumerant value is a global
constant. Otherwise, the value is added to the specified enumeration.
Examples of <<tag-required-examples,various types of extension enumerants>>
are given below.
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.

=== Type tags
tag:type specifies a required (or removed) type defined in a
tag:types block. Most types are picked up implicitly by using the
tag:type tags of commands, but in a few cases, additional types need
to be specified explicitly. It is unlikely that a type would ever be
removed, although this usage is allowed by the schema. The tag has no
content, but contains elements:
* attr:name - required. Name of the type.
* attr:comment - optional. Arbitrary string (unused).

== Examples of Extension Enumerants
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).

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 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

For people new to the Registry, it will not be immediately obvious how
to make changes. This section includes some tips and examples that will
help you make changes to the Vulkan headers by changing the Registry XML
description.
First, follow the steps described to <<starting,get the Vulkan Github
repository>> containing the registry and assemble the tools necessary to
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: * 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.

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 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.

added, create appropriate new tag:type, tag:enums, tag:enum, or
tag:command tags defining the interface in question.
* Make sure that all added types and commands appropriately tag their
dependencies on other types by adding nested tag:type tags.
* Make sure that each new tag defines the name of the corresponding
type, enum group, constant, or command, and that structure/union
types and commands tag the types and names of all their members and
parameters. This is essential for the automatic dependency process
to work.
If you are _modifying_ existing APIs, just make appropriate changes
in the existing tags.
Once the definition is added, proceed to the next section to create
dependencies on the changed feature.
== API Feature Dependencies
When you add new API elements, they will not result in corresponding changes
in the generated header unless they are _required_ by the interface
being generated. This makes it possible to include different API versions
and extensions in a single registry and pull them out as needed. So you must
introduce a dependency on new features in the corresponding tag:feature
tag.
Initially, the only API feature is Vulkan 1.0, so there is only one

Change log for July 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

Inside the tag:feature tag are nested multiple tag:require tags. These
are just being used as a logical grouping mechanism for related parts of
Vulkan 1.0 at present, though they may have more meaningful roles in the
future if different API profiles are defined.
=== API Feature Walkthrough
This section walks through the first few required API features in the
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 22, 2016 Vulkan 1.0.22 spec update: * Bump API patch number and header version number to 22 for this update.

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.

first causes this to appear first in the output file.
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`

Note that `vk_platform` does not correspond to an actual C type, but instead
to a collection of freeform preprocessor includes and macros and comments.
Most other tag:type tags do define a specific type and are much simpler, but
this approach can be used to inject arbitrary C into the Vulkan headers
*when there is no other way*. In general inserting arbitrary C is strongly
discouraged outside of specific special cases like this.
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 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 July 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

Change log for July 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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.

Change log for August 26, 2016 Vulkan 1.0.25 spec update: * Bump API patch number and header version number to 25 for this update. * Structurally change the specification so that multiple extensions are included in the +1.0+ git branch, and specifications will include or not include those extensions at build time based on options passed to the Makefile. See +doc/specs/vulkan/README.html+ and the ``Layers and Extensions'' section of the ``Vulkan Documentation and Extensions'' document for more information on this change. * Register and publish new extensions in the single-branch form: ** +VK_NV_external_memory_capabilities+ ** +VK_NV_external_memory+ ** +VK_NV_external_memory_win32+ ** +VK_NV_win32_keyed_mutex+ Github Issues: * Clarify description of GetInstanceProcAddr and GetDeviceProcAddr (public issue 212). * Add SPIR-V <<textures-operation-validation, instruction validation>> for single-sampled images (public issue 316). * Fix spelling of ``tesselation'' in a few places and note it as an exception to the American spelling rules convention (public issue 327). * Fix Makefile to create output directory for ``styleguide'' target (public issue 329). * Fix numerous minor issues with incorrectly tags on enumerant names and table titles (public issue 330). * Generate specversion.txt date in UTC time and RFC 2822 format (public issue 335). * Convert link to the SPIR-V Specification for flink:VkShaderModuleCreateInfo into an internal link to the normative reference (public issue 336). * Add ename:VK_ERROR_OUT_OF_MEMORY error code to flink:vkCreateDebugReportCallbackEXT (public issue 337). Internal Issues: * Update style guide regarding use of code:NULL and dname:VK_NULL_HANDLE (internal issue 393). * Change the definition of latexmath:[$q$] in the <<textures-image-level-selection,texture image level selection>> section to be the index of the maximum defined level for the view, not the number of levels in the view (internal issue 406). * Allow developers to override dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE with their own binary-compatible definition (internal issue 439). * Fix +vk_platform.h+ conditional logic causing compile failure with some Android compilers (internal issue 441). * Implement the single-branch model as described above (internal issue 461).

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 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`

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 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 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.

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 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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).

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 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: * 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 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 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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.

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.

This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs.

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 September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update.

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).

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.

VKAPI_ATTR VkResult VKAPI_CALL vkCreateInstance(
Change log for July 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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.

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: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919).

The tag:proto tag defines the return type and function name of the
command. The tag:param tags define the command's parameters in the order
in which they are passed, including the parameter type and name. The contents
are laid out in the same way as the structure tag:member tags described
previously.
== More Complicated API Representations
The registry schema can represent a good deal of additional information, for
example by creating multiple tag:feature tags defining different API
versions and extensions. This capability is not yet relevant to Vulkan.
Those capabilities will be documented as they are needed.
== More Complicated Output Formats And Other Languages
The registry schema is oriented towards C-language APIs. Types and commands
are defined using syntax which is a subset of C, especially for structure
members and command parameters. It would be possible to use a
language-independent syntax for representing such information, but since we
are writing a C API, any such representation would have to be converted into
C anyway at some stage.

in the Python scripts. This output generator is specialized for C, but the
design of the scripts is intended to support writing output generators for
other languages as well as purposes such as documentation (e.g. generating
asciidoc fragments corresponding to types and commands for use in the API
specification and reference pages). When targeting other languages, the
amount of parsing required to convert type declarations into other languages
is small. However, it will probably be necessary to modify some of the
boilerplate C text, or specialize the tags by language, to support such
generators.
== Additional Semantic Tagging
The schema is being extended to support semantic tags describing
various properties of API features, such as:

(non-`NULL`, normalized floating-point, etc.)
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.

* length of arrays corresponding to function pointer parameters
* miscellaneous properties of commands such as whether the application
or system is responsible for threadsafe use; which queues they may
be issued on; whether they are aliases or otherwise related to other
commands; etc.
These tags will be used by other tools for purposes such as helping
create validation layers, generating serialization code, and so on. We
would like to eventually represent everything about the API that is
amenable to automatic processing within the registry schema. Please make
suggestions on the Github issue tracker.

== Stability of the XML Database and Schema
The Vulkan XML schema is evolving in response to corresponding changes
in the Vulkan API and ecosystem. Most such change will probably be
confined to adding attributes to existing tags and properly expressing
the relationships to them, and making API changes corresponding to
accepted feature requests. Changes to the schema should be described in

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`
2018-03-07 12:18:52 +00:00
* 2018-03-07 - Updated for Vulkan 1.1 release.
* 2018-02-21 - Add descriptions of the attr:extnumber and attr:alias
attributes used for defining tag:enum attributes, the attr:alias
attribute used for defining tag:type aliases, the attr:name and
attr:alias attributes used for defining tag:command aliases, the
attr:platform attribute of tag:extension tags, and the attr:feature
attribute of tag:require tags; and update the document to the header
naming and grouping scheme used starting in Vulkan 1.1.
* 2018-01-07 - Add tag:platforms and tag:platform tags for describing
Vulkan platform names and preprocessor symbols.
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`
2017-09-15 05:41:33 +00:00
* 2017-09-10 - Define syntax of member and parameter attr:altlen

* 2017-09-01 - Define syntax of member and parameter attr:len attributes
consistently and correctly for current uses of latexmath:
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. Update the registry schema and documentation accordingly. New Extensions: * `VK_AMD_shader_fragment_mask` (and related `GL_AMD_shader_fragment_mask` GLSL extension) * `VK_EXT_sample_locations` * `VK_EXT_validation_cache`
2017-09-04 10:06:55 +00:00

Change log for July 15, 2017 Vulkan 1.0.55 spec update: * Bump API patch number and header version number to 55 for this update. Github Issues: * Removed unintended optional parameter in +vk.xml+ from the pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted in the generation of an incorrect implicit valid usage clause allowing pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is non-zero (public issue 491). * Add missing attribute to +vk.xml+ documenting that slink:VkSwapchainCounterCreateInfoEXT extends slink:VkSwapchainCreateInfo (public issue 510). * Add const qualifier for some `VK_EXT_debug_market` extension command parameters that were missing it (public issue 513). * Fix definition of q and level~base~ in <<textures-image-level-selection,Image Level(s) Selection>> (public issue 515). * Clarify lifetime requirement for slink:VkRenderPass objects used in object creation (public issue 516). * Fix link to floating/normalized fixed-point conversion from <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue 521). Internal Issues: * Update the style guide to include the general structure of a Vulkan command name, the specific rule for using "`Get`" vs. "`Enumerate`" in names, and a table of verbs commonly used in command names (spinoff of internal issue 753). * Clarified the behavior of automatic layout transitions in case of attachment views that are 2D or 2D array views of 3D images. In addition, restructured the valid usage clauses corresponding to the members of the slink:VkImageSubresourceRange structure and added missing valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer members (internal issues 803, 849). * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a push_constant declaration (internal issue 919). Other Commits: * Modify <<synchronization-framebuffer-regions, Framebuffer Region Dependencies>> to use synchronization scope terminology. * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the `VK_EXT_swapchain_colorspace` extension. * Replace XML comments with `comment` attributes and/or tags, to enable tools which transform the XML without loss of information. * Replace `validextensionstructs` with `structextends`, which is tagged in the child structure instead of the parent. This makes it slightly simpler to add new structs to the XML, causes fewer merge conflicts, and the information is kept localized to the extension structures where it belongs. The old `validextensionstructs` attributes will be retained until we're certain this doesn't cause problems with known consumers of +vk.xml+.

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.

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 September 16, 2016 Vulkan 1.0.27 spec update: * Bump API patch number and header version number to 27 for this update. Github Issues: * Weaken flink:vkGetPipelineCacheData invariance conditions; previous conditions were stronger than agreed and can't be guaranteed (public issue 280). * Add link to "Vulkan Loader Specification and Architecture Overview" document to Normative References section (public issue 359). Internal Issues: * Be more clear in the <<interfaces-resources-layout-std140, uniform buffer layout>> section that block offsets can be out of order (internal issue 396). * Document that extension authors should add support for their extensions to the validation layers (internal issue 398). * Clarify that the valid range of depth clear values should be limited to the 0..1 range and that copies to depth aspect must also be in this range (internal issue 412). * Specify ``a'' vs. ``an'' use in the style guide (internal issue 432). * Increase the maximum pname:nonCoherentAtomSize value in the <<features-limits-required,Required Limits>> section from 128 to 256 (internal issue 435). * Fix vk_platform.h for compiler errors on some Android platforms (internal issue 441). * Clarify that slink:VkPhysicalDeviceFeatures::pname:pEnabledFeatures == `NULL` disables all features, including the "required" feature pname:robustBufferAccess (internal issue 479). Other Issues: * Expand style guide and make it more self-consistent. * Use ISO 8601 date format everywhere. * Emphasise the correct way of using slink:VkSurfaceCapabilitiesKHR::pname:maxImageCount. * Added +VK_EXT_validation_flags+ extension for validation flag mechanism. * Fix an <<credits,author credit>> to include their current employer.

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 September 16, 2016 Vulkan 1.0.27 spec update: * Bump API patch number and header version number to 27 for this update. Github Issues: * Weaken flink:vkGetPipelineCacheData invariance conditions; previous conditions were stronger than agreed and can't be guaranteed (public issue 280). * Add link to "Vulkan Loader Specification and Architecture Overview" document to Normative References section (public issue 359). Internal Issues: * Be more clear in the <<interfaces-resources-layout-std140, uniform buffer layout>> section that block offsets can be out of order (internal issue 396). * Document that extension authors should add support for their extensions to the validation layers (internal issue 398). * Clarify that the valid range of depth clear values should be limited to the 0..1 range and that copies to depth aspect must also be in this range (internal issue 412). * Specify ``a'' vs. ``an'' use in the style guide (internal issue 432). * Increase the maximum pname:nonCoherentAtomSize value in the <<features-limits-required,Required Limits>> section from 128 to 256 (internal issue 435). * Fix vk_platform.h for compiler errors on some Android platforms (internal issue 441). * Clarify that slink:VkPhysicalDeviceFeatures::pname:pEnabledFeatures == `NULL` disables all features, including the "required" feature pname:robustBufferAccess (internal issue 479). Other Issues: * Expand style guide and make it more self-consistent. * Use ISO 8601 date format everywhere. * Emphasise the correct way of using slink:VkSurfaceCapabilitiesKHR::pname:maxImageCount. * Added +VK_EXT_validation_flags+ extension for validation flag mechanism. * Fix an <<credits,author credit>> to include their current employer.

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.

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
