Change log for January 15, 2018 Vulkan 1.0.68 spec update: * Bump API patch number and header version number to 68 for this update.Github Issues: * Added more details in the <<extended-functionality-extensions-compatibility, Extension Compatibility>> section, allowing explicit incompatibilities, and simplify corresponding language in the style guide, which now defers to the API Specification on this point (public issue 638). * Fix typo in description of slink:VkCommandBufferLevel::pname:level (public issue 651). * Only include extension-dependent valid usage statement for slink:VkImageSubresourceRange, and note that the extension names for header files described in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section are only valid links, when the specification being viewed is built with the corresponding extensions enabled (public issue 652).Internal Issues: * Add language to elink:VkResult specifying that when commands return an error, output parameter contents are undefined instead of unmodified (except for pname:sType and pname:pNext). Note that this is a behavior change. Add notes calling out slink:VkImageFormatProperties as an exception (internal issue 1118). * Add "`general-purpose`" to the style guide, and correct existing uses of "`general purpose`" as an adjective (internal issue 1121). * Add the ename:VK_DEBUG_REPORT_OBJECT_TYPE_VALIDATION_CACHE_EXT_EXT token for the `VK_EXT_validation_cache` extension, following the same naming pattern as other tokens in the extension, but keep the old ename:VK_DEBUG_REPORT_OBJECT_TYPE_VALIDATION_CACHE_EXT token around for backwards compatibility (internal issue 1126).Other Issues: * Specify that flink:vkCmdSetDiscardRectangleEXT does not affect copies or clears, matching existing language for the scissor rectangle test. * Move the <<boilerplate-sType, pname:sType>> definition from the boilerplate appendix to the Fundamentals chapter, putting it together with the valid usage of pname:sType rather than having the definition split across two places. * Inline all of the etext:Vk*Flags definitions, moving each one from the boilerplate appendix to appear either after the corresponding etext:Vk*FlagBits value if one is defined, or after the first structure that includes them if not.
Change log for February 19, 2018 Vulkan 1.0.69 spec update: * Bump API patch number and header version number to 69 for this update.Github Issues: * Clean up description of synchronization for flink:vkAcquireNextImageKHR (public issue 626). * Move valid usage statements requiring offset and extent to respect image transfer granularity requirements of the queue family they are submitted against from slink:VkImageCopy and slink:VkBufferImageCopy to the corresponding flink:vkCmdCopyImage, flink:vkCmdCopyBufferToImage, and flink:vkCmdCopyImageToBuffer commands, where are relevant information is known (public issue 654). * Clarify that flink:vkGetDeviceProcAddr only supports device-level commands (public issue 655).Internal Issues: * Associate each elink:VkDescriptorType with a type of descriptor, and link to descriptions of those types (internal issue 860). * Rework valid usage extraction script to better utilize and respond to spec markup, and fix some spec markup accordingly (internal issues 846, 909, 945). * Rephrase flink:vkCmdPushConstants valid usage to allow overlapping push constant ranges in different shader stages (internal issue 1103). * Fix problem with diff_html target in extension.rb (internal issue 1104). * Modify valid usage statements for slink:VkClearDepthStencilValue, slink:VkGraphicsPipelineCreateInfo, slink:VkViewport, and flink:vkCmdSetDepthBounds, and the description of vkCmdSetDepthBias, to clarify that clamping is applied if and only if the `VK_EXT_depth_range_unrestricted` is not enabled (internal issue 1124), in versions of the specification built with that extension included. * Resolve contradictions and use of undefined "`per-sample shading`" term in the <<primsrast-sampleshading, Sample Shading>> and <<shaders-fragment-execution, Fragment Shader Execution>> sections; for the <<features-features-sampleRateShading, sampleRateShading feature>>; for code:FragCoord, code:SampleId, and code:SamplePosition; and for slink:sname:VkPipelineMultisampleStateCreateInfo (internal issue 1134). * Clarify the meaning of the ptext:maxDescriptorSet* limits in footnote 8 of the <<features-limits-required,Required Limits>> table (internal issue 1139). * Fix broken NOTE markup in slink:VkSamplerCreateInfo.txt (internal issue 1140). * Remove extend comparison language from valid usage statement for slink:VkImageCreateInfo, turning it into a simple validation of pname:mipLevels against pname:maxMipLevels (internal issue 1151). * Update valid usage statements for slink:VkImageCopy when the `VK_KHR_maintenance1` extension is enabled to allow multi-slice 2D <-> 3D copies when the pnaem:extent.depth parameter specifies the number of layers being copied, and matches the slink:VkImageSubresourceLayers.layerCount of the 2D image (internal issue 1152). * Rephrase memory / control barrier rules in the <<spirvenv-module-validation, Validation Rules within a Module>> section to avoid "`not use none`", which could be misconstrued to allow no synchronization semantics, and only storage class semantics (internal issue 1154).Other Issues: * Move GLSL extension specifications to the KhronosGroup/GLSL repository on Github. * Add missing description of ename:VK_FILTER_CUBIC_IMG enum to slink:VkFilter. * Update description of code:PrimitiveId in the <<interfaces-builtin-variables,Built-In Variables>> section to clarify its behavior. * Disallow disjoint images from being used with dedicated-memory images in slink:VkMemoryDedicatedAllocateInfoKHR. * Update README to suggest older versions of "mathematical" and "ruby-gems" packages for use on Cygwin. * Fix typosNew Extensions: * `VK_AMD_buffer_marker`
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 16, 2018 Vulkan 1.1.71 spec update: * First public update for Vulkan 1.1.Github Issues: * Refer to standard sparse image block shape format tables explicitly in the <<sparsememory-standard-shapes, Standard Sparse Image Block Shapes>> section (public issue 93). * Add the missing definition of the code:LocalInvocationIndex decoration in the <<interfaces-builtin-variables, Built-In Variables>> section (public issue 532). * Clarify dynamic state definition in the introduction to the <<pipelines, Pipelines>> section and the new <<pipelines-dynamic-state, Dynamic State>> subsection (public issue 620). * Clarified deprecation statement in the `VK_AMD_negative_viewport_height` appendix (public issue 674). * Fix parameter descriptions for flink:vkCreateIndirectCommandsLayoutNVX (public issue 677).Internal Issues: * Remove description of <<primsrast-points, rasterization point size>> being taken from the tessellation control shader, since there are no circumstances under which you can have TCS without TES (internal issue 522). * Define <<copies-images-format-size-compatibility, _size-compatible_ image formats>> for flink:vkCmdCopyImage, add it to the glossary, and use that definition for slink:VkImageViewCreateInfo (internal issue 771). * Change brief descriptions of enumerant names, and of parameters which are enumerants, from "`enum *indicates*`" to "`enum *specifies*`" for consistency, and add a markup style guide rule (internal issue 862). * Clarify how execution dependencies interact with <<synchronization-submission-order, submission order>> at numerous places in the <<renderpass, Render Pass>> and <<synchronization, Synchronization>> chapters (internal issue 1062). * Clarify statement in the <<interfaces-resources-setandbinding, DescriptorSet and Binding Assignment>> section that only interface variables statically used by the entry point used in a pipeline must be present in the descriptor set layout (internal issue 1172). * Flip sparse image diagrams with partially full mip levels vertically, to match graph origins of other image diagrams (internal issue 1176). * Update new SVG diagrams to have consistent style and base font size, increase consistency of primitive topology diagrams, and add a section to the style guide on creating and editing images in a consistent style (internal issue 1177). * Resolve problems with valid usage statement extraction by fixing existing VUID tags for interfaces promoted to version 1.1 and fixing conditional directives around VUID-VkMemoryDedicatedAllocateInfo-image-01797 (internal issue 1184). * Strip `KHR` suffixes from a few interfaces promoted to Vulkan 1.1 that were missed previously (internal issue 1185). * Restrict code:OpImageQuerySizeLod and code:OpImageQueryLevels to only work on code:Image operands with their code:Sampled operand set to 1. In other words, these operations are not defined to work with storage images (internal issue 1193). * Recycle extension slot for extension #82 in `vk.xml`. This extension was never published (internal issue 1195). * Add an issue to the `VK_KHR_maintenance1` appendix noting that zero height viewports are allowed when this extension is enabled (internal issue 1202). * Fix slink:VkDescriptorSetLayoutBinding description so that shader stages always use descriptor bindings, not the other way around (internal issue 1206). * Fix field name for slink:VkInputAttachmentAspectReference::pname:inputAttachmentIndex (internal issue 1210).Other Issues: * Fix a few broken links in the <<versions-1.1, Version 1.1>> appendix. * Replace a few old refBegin/refEnd tags with open block markup around interfaces, and remove old KHX VUID tags that were breaking the valid usage statement extraction. * Fix error codes accidentally tagged as success codes in `vk.xml` for flink:vkGetSwapchainCounterEXT. * Added valid usage statements for ftext:vkBind*Memory2 input structures stext:VkBind*MemoryInfo, and fix a pname:image -> pname:buffer typo in a couple of places. * Fix swapped descriptions of elink:VkDescriptorType enums ename:VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE and ename:VK_DESCRIPTOR_TYPE_STORAGE_IMAGE (reported via tweet).New Extensions: * `VK_ANDROID_external_memory_android_hardware_buffer`
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 April 15, 2018 Vulkan 1.1.73 spec update: * Update release number to 73.Github Issues: * Refine swapchain association with surface for slink:VkSwapchainKHR, with matching valid usage statements for slink:VkSwapchainCreateInfoKHR and discussion following the <<swapchain-wsi-image-create-info>> table (public issue 637). * Re-remove several valid usage statements from slink:VkImageCreateInfo that had previously been removed at the time that ename:VK_IMAGE_CREATE_EXTENDED_USAGE_BIT was introduced. These statements had incorrectly been restored due to an glitch while merging from the old `1.0` branch to the current `master` branch (public issue 683).Internal Issues: * Fix reference page generation and configure build to generate reference pages 1.1 with all extensions, rather than core only, as was the case for the 1.0 ref pages (internal issues 484, 1056, 1205). * Require that slink:VkMemoryDedicatedRequirements::pname:prefersDedicateAllocation is ename:VK_TRUE when slink:VkMemoryDedicatedRequirements::pname:requiresDedicateAllocation is ename:VK_TRUE (internal issue 1222). * Fix Ruby extension code so `diff_html` Makefile target works (internal issue 1230). * Update `genRelease` script to generate 1.1 + all extensions reference pages - but not the single-page HTML / PDF versions, which are even larger than the API spec (internal issue 1245).Other Issues: * Add missing attributes to `vk.xml` for `VK_ANDROID_native_buffer`. * Specify that the slink:VkAttachmentDescription::pname:format member is the format of the image *view* that will be used for the attachment. * Use core sname:VkPhysicalDeviceFeatures2 in the `structextends` `vk.xml` attribute for sname:VkPhysicalDeviceDescriptorIndexingFeaturesEXT and sname:VkPhysicalDeviceDescriptorIndexingPropertiesEXT, rather than the KHR equivalent it was promoted from. * Fix the "`Fragment Input Attachment Interface`" glossary entry to match the specification body. * Clarify the interaction of sRGB images used as storage or texel buffers with <<textures-output-format-conversion, Texel Output Format Conversion>>. * Moved three valid usage statements from slink:VkRenderPassMultiviewCreateInfo up to slink:VkRenderPassCreateInfo, and added a new valid usage statement for slink:VkRenderPassInputAttachmentAspectCreateInfo. * Added valid usage statements for slink:VkBufferMemoryBarrier and slink:VkImageMemoryBarrier reflecting the global requirement that "`non-sparse resources must be bound to memory before being recorded to command`".New Extensions:
Change log for April 21, 2018 Vulkan 1.1.74 spec update: * Update release number to 74.Github Issues: * Clarify which buffer locations are accessed in flink:vkCmdCopyBufferToImage valid usage statements (public issue 676). * Refine description of <<extended-functionality-extensions-dependencies, extension dependencies>>, related NOTE in the <<extended-functionality-extensions, Extensions>> section, and "`Required Extensions`" glossary term (public pull request 693). * Add support for specifying required Vulkan core version in `vk.xml` and the extension metadoc generator (public issue 696). * Update .gitignore for directory reorganization (public pull request 699). * Fix typo (public pull request 703).Internal Issues: * Update valid usage of slink:VkClearRect::pname:layerCount (internal issue 1241).Other Issues: * Fix typo in <<NV_geometry_shader_passthrough>> issues list.
Change log for May 16, 2018 Vulkan 1.1.75 spec update: * Update release number to 75.Github Issues: * Use Github handles (e.g. @handle) for contact information in vk.xml, when available (partial fix for public issue 630). * Add size invariance guarantee to slink:VkMemoryRequirements for buffer/image memory requirements (public issue 661). * Correct scope (conditional constructs) in valid usage statement for slink:VkBindImageMemoryInfo (public pull request 684). * Clean up minor markup issues and typos in the `VK_ANDROID_external_memory_android_hardware_buffer` extension appendix (public pull request 698). * Modify registry processing script to avoid irrelevant warnings of benign enumerant redefinitions (public pull request 705). * Fix some duplicate words and some misspelled "`stagess`" (public pull request 712)Internal Issues: * Enable continuous integration tests on the internal Khronos gitlab server by adding a .gitlab-ci.yml file. Note: this does not implement CI on the public Github repository (internal issue 408). * Add link from description of depth clamping in the <<fragops-depth, depth test>> section to the slink:VkPipelineRasterizationStateCreateInfo::pname:depthClampEnable parameter which enables it, making it easily searchable / findable (internal issue 1125). * Clarify that arrays of arrays of descriptors are not allowed in the <<interfaces-resources-descset, Descriptor Set Interface>> and <<interfaces-resources-setandbinding, DescriptorSet and Binding Assignment>> sections (internal issue 1192). * Comment out some redundant nested asciidoctor conditionals in the slink:VkImageViewCreateInfo valid usage block, and explain in all cases why the redundant conditional exist and are commented out (internal issue 1231). * Move a valid usage statement from slink:VkCommandPoolCreateInfo to the parent flink:vkCreateCommandPool, where the device queue is known (internal issue 1233). * Add new slink:VkBaseInStructure and slink:VkBaseOutStructure types which can be used by extensions and implementations for handling Vulkan sType/pNext style structures in a more generic way (internal issue 1265). * Clarify that slink:VkAndroidHardwareBufferFormatPropertiesANDROID::pname:formatFeatures only applies to external-format images. Add references to this in valid usage statements that previously only referred to slink:VkFormatProperties (internal issue 1244). * Fix the description of elink:VkPipelineCreateFlagBits enumerant ename:VK_PIPELINE_CREATE_VIEW_INDEX_FROM_DEVICE_INDEX_BIT to match the name (internal issue 1279). * Add a NOTE to the <<interfaces-resources-setandbinding, DescriptorSet and Binding Assignment>> section making it clear that variables sharing a storage class may use identical descriptor set and bindings. Specifically state the sometimes misunderstood ability to have one or more differently typed image descriptors sharing a descriptor set and binding (internal SPIR-V issue 264). * Make DynamicIndexing features and capabilities also control the uniformity of the descriptor used in memory access instructions in the <<interfaces-resources-descset, Descriptor Set Interface>> section. This makes them also apply to variable_pointer usage, which can bypass the array indexing operation (internal SPIR-V issue 289).Other Issues: * Correct flink:vkCmdBlitImage limitations on cubic blits to be 2D only, not 3D. * Update valid usage statements for slink:VkRenderPassCreateInfo and slink:VkInputAttachmentAspectReference. * Move YCbCr-related VU statements from slink:VkDescriptorImageInfo to slink:VkWriteDescriptorSet, where all needed information is known, and remove redundant statements. * Move SPIR-V restriction that images be of either sampled or storage types from the <<interfaces-resources-descset, Descriptor Set Interface>> section to the <<spirvenv-module-validation, Validation Rules within a Module>> section of the SPIR-V appendix.
Change log for May 25, 2018 Vulkan 1.1.76 spec update: * Update release number to 76.Internal Issues: * Add an exception clause to the license on `vk.xml`, enabling its use with GPL-based projects (internal issue 1017). * Remove the generated `vulkan_ext.[ch]` files, which are no longer supported. Add `src/ext_loader/README.md` explaining why, and update files in `xml/` to not generate them by default (internal issue 1268)Other Issues: * Fix typos in valid usage statements for the ftext:vkDrawIndexedIndirectCount* commands, replacing sizeof(VkDrawIndirectComment) with sizeof(VkDrawIndexedIndirectCommand). * Modify the <<spirvenv-module-validation, Validation Rules within a Module>> section to require code:NonReadable or code:NonWriteable in SPIR-V code for images with an image format of code:Unknown if one of the requisite code:shaderImageReadWithoutFormat or code:shaderImageWriteWithoutFormat features is disabled.New Extensions: * `VK_KHR_get_display_properties2` * `VK_KHR_draw_indirect_count`
