Change log for January 05, 2019 Vulkan 1.1.97 spec update: * Update release number to 97. Public Issues: * Add a special case to the <<renderpass-compatibility, Render Pass Compatibility>> rules allowing single-subpass renderpasses to be compatible even if they have different resolve attachment references (public issue 835). * Fix the miss shader binding table record address rule in the <<shader-binding-table-indexing-rules, Miss Shaders>> section to index by code:missIndex, not code:sbtOffset (public issue 875). Internal Issues: * Add a missing anchor to the elink:VkSamplerCreateFlagBits language (internal issue 1483). * Add missing implicit valid usage include for slink:VkHdrMetadataEXT and corresponding `noautovalidity` attributes in `vk.xml` for the externally-defined metadata properties (internal issue 1514). * Remove restrictions on the `mask` parameter of SPIR-V's code:OpGroupNonUniformXor in the <<spirvenv-module-validation, Validation Rules within a Module>> appendix (internal merge request 2971). * Restore `noautovalidity` attribute for slink:VkPipelineViewportWScalingStateCreateInfoNV::pname:pViewportWScalings in `vk.xml` (internal merge request 2975). * Update copyright dates on Khronos-copyrighted files to 2019 (internal merge request 2980). New Extensions: * `VK_KHR_depth_stencil_resolve` * `VK_EXT_buffer_device_address` * `VK_EXT_memory_budget` * `VK_EXT_memory_priority` * `VK_EXT_validation_features`

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

Change log for May 12, 2017 Vulkan 1.0.49 spec update: * Bump API patch number and header version number to 49 for this update. Github Issues: * Modify reference page extraction script to make internal links to spec anchors refer to the core specification instead of being dangling links (public issue 455). * Fix GL_KHR_vulkan_glsl typo and add a nor-normative mapping to the newly published StorageBuffer class (public issue 466). * Both flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties return ename:VK_ERROR_LAYER_NOT_PRESENT, which covers the error case of an application providing a layer name that wasn't returned by ftext:vkEnumerate{Instance|Device}LayerProperties (public issue 487). * The specification for flink:VkApplicationInfo::apiVersion says that the driver must return ename:VK_ERROR_INCOMPATIBLE_DRIVER in the case that pname:apiVersion specifies a non-supported version. That means that the valid usage should not also state that, and so the VU statement is removed. The VU had language about "`an effective substitute`" that would have been lost, and so it was moved to the pname:apiVersion description (public issue 488). Internal Issues: * Modify implicit validity generator script to assign asciidoc anchors to all valid usage statements it generates, and reflow.py script to insert Valid Usage ID (VUID) tags into the specification source files for explicit valid usage statements. This has no semantic effects on the specification, but will support the validation layer's detection of valid usage violations and allow it to link into the corresponding part of the specification (internal issue 583). * Assign VUID tags to all explicit VU statements and document the process and tag format in the style guide (internal issue 583). * Clarify the rules of whether to structure new functionality as instance extensions, device extensions, or both in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section (internal issue 749). * Require that SPIR-V run-time arrays are only used with the code:BufferBlock decoration (internal issue 750). * Fix implicit and explicit valid usage statements for slink:VkWriteDescriptorSet::pname:dstSet (internal issue 767) * Fix SPIR-V code sample for ename:VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER in the <<descriptorsets-uniformtexelbuffer, Uniform Texel Buffer>> section (internal issue 770). * Clarify that disabling depth testing also disables depth writes in the <<fragops-ds-state, Depth and Stencil Operations>> section (internal issue 775). * flink:VkDescriptorImageInfo::pname:imageLayout must match the actual imageLayout at the time the image is accessed. This was in the spec text, but needed an associated valid usage statement. * Note that only 32-bit atomic operations are supported in the <<spirvenv-module-validation, Validation Rules within a Module>> section. * Note that code:UniformConstant variables must not have initializers in the <<spirvenv-module-validation, Validation Rules within a Module>> section. * Add a new elink:VkObjectType enumeration to the core API, promoted from elink:VkDebugObjectTypeEXT, since it is used for much more than just the debug_report extension. New Extensions: * `VK_KHR_get_surface_capabilities2` * `VK_KHR_shared_presentable_image`

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`

This extension provides new entry points to query device surface
capabilities in a way that can be easily extended by other extensions,
without introducing any further entry points.
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`

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

* `VK_KHR_surface2`
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`

* One extension, combining a separate display-specific query extension.
Change log for May 12, 2017 Vulkan 1.0.49 spec update: * Bump API patch number and header version number to 49 for this update. Github Issues: * Modify reference page extraction script to make internal links to spec anchors refer to the core specification instead of being dangling links (public issue 455). * Fix GL_KHR_vulkan_glsl typo and add a nor-normative mapping to the newly published StorageBuffer class (public issue 466). * Both flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties return ename:VK_ERROR_LAYER_NOT_PRESENT, which covers the error case of an application providing a layer name that wasn't returned by ftext:vkEnumerate{Instance|Device}LayerProperties (public issue 487). * The specification for flink:VkApplicationInfo::apiVersion says that the driver must return ename:VK_ERROR_INCOMPATIBLE_DRIVER in the case that pname:apiVersion specifies a non-supported version. That means that the valid usage should not also state that, and so the VU statement is removed. The VU had language about "`an effective substitute`" that would have been lost, and so it was moved to the pname:apiVersion description (public issue 488). Internal Issues: * Modify implicit validity generator script to assign asciidoc anchors to all valid usage statements it generates, and reflow.py script to insert Valid Usage ID (VUID) tags into the specification source files for explicit valid usage statements. This has no semantic effects on the specification, but will support the validation layer's detection of valid usage violations and allow it to link into the corresponding part of the specification (internal issue 583). * Assign VUID tags to all explicit VU statements and document the process and tag format in the style guide (internal issue 583). * Clarify the rules of whether to structure new functionality as instance extensions, device extensions, or both in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section (internal issue 749). * Require that SPIR-V run-time arrays are only used with the code:BufferBlock decoration (internal issue 750). * Fix implicit and explicit valid usage statements for slink:VkWriteDescriptorSet::pname:dstSet (internal issue 767) * Fix SPIR-V code sample for ename:VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER in the <<descriptorsets-uniformtexelbuffer, Uniform Texel Buffer>> section (internal issue 770). * Clarify that disabling depth testing also disables depth writes in the <<fragops-ds-state, Depth and Stencil Operations>> section (internal issue 775). * flink:VkDescriptorImageInfo::pname:imageLayout must match the actual imageLayout at the time the image is accessed. This was in the spec text, but needed an associated valid usage statement. * Note that only 32-bit atomic operations are supported in the <<spirvenv-module-validation, Validation Rules within a Module>> section. * Note that code:UniformConstant variables must not have initializers in the <<spirvenv-module-validation, Validation Rules within a Module>> section. * Add a new elink:VkObjectType enumeration to the core API, promoted from elink:VkDebugObjectTypeEXT, since it is used for much more than just the debug_report extension. New Extensions: * `VK_KHR_get_surface_capabilities2` * `VK_KHR_shared_presentable_image`

2) Should additional WSI query functions be extended?
*RESOLVED*:
* flink:vkGetPhysicalDeviceSurfaceCapabilitiesKHR: Yes.
The need for this motivated the extension.
* flink:vkGetPhysicalDeviceSurfaceSupportKHR: No.
Currently only has boolean output.
Extensions should instead extend
flink:vkGetPhysicalDeviceSurfaceCapabilities2KHR.
* flink:vkGetPhysicalDeviceSurfaceFormatsKHR: Yes.
* flink:vkGetPhysicalDeviceSurfacePresentModesKHR: No.
Recent discussion concluded this introduced too much variability for
applications to deal with.
Extensions should instead extend
flink:vkGetPhysicalDeviceSurfaceCapabilities2KHR.
* flink:vkGetPhysicalDeviceXlibPresentationSupportKHR: Not in this
extension.
* flink:vkGetPhysicalDeviceXcbPresentationSupportKHR: Not in this
extension.
* flink:vkGetPhysicalDeviceWaylandPresentationSupportKHR: Not in this
extension.
* flink:vkGetPhysicalDeviceWin32PresentationSupportKHR: Not in this
extension.
