* Update release number to 95.
Public Issues:
* Fix valid usage and XML issues found in public issues 789 and 790 for
the `VK_EXT_debug_utils` extension (public pull request 794).
* Replace references to `VK_NV_dedicated_allocation` with links to the
corresponding slink:slink:VkMemoryDedicatedRequirements and
slink:slink:VkMemoryDedicatedAllocateInfo structures in the description
of elink:VkExternalMemoryFeatureFlagBits (public issue 801).
* Fix miscellaneous minor markup and spelling issues in
`VK_NV_ray_tracing` extension (public pull request 860).
* Remove "returnedonly" from XML for
slink:VkPhysicalDeviceInlineUniformBlockFeaturesEXT and
slink:VkPhysicalDeviceVulkanMemoryModelFeaturesKHR (public issue 862).
Internal Issues:
* Add to the description of the
<<features-limits-maxComputeSharedMemorySize,
pname:maxCompureSharedMemorySize>> feature to state the shared variables
should be packed at least as tightly as std430 (internal issue 1386).
* Fix and clarify various references to image and image view usage in
flink:vkCmdBindShadingRateImageNV, flink:vkCmdBeginRenderPass, and
slink:VkImageStencilUsageCreateInfoEXT (internal issue 1432).
* Require that the slink:VkImage mipmap chain match the Android hardware
buffer mipmap chain for slink:VkMemoryAllocateInfo (internal issue
1479).
* Fix the definition of slink:VkSwapchainCreateInfoKHR valid usage
statement 01778 (Vulkan-ValidationLayers!15)
* Fix descriptions of <<interfaces-builtin-variables-launchid,
code:LaunchIDNV>> and <<interfaces-builtin-variables-launchsize,
code:LaunchSizeNV>> to code:uvec3.
New Extensions:
* `VK_KHR_shader_float16_int8`
* `VK_KHR_shader_float_controls`
* Update release number to 94.
Public Issues:
* Use the terms "`texel block`" and "`texel block size`" instead of "`data
element`" and "`element size`", and define "`element`" as an array slot.
In addition to the terminology changes, retitled the <<texel-block-size,
Representation and Texel Block Size>> section and added texel block size
/ no. of texels/block information to the
<<features-formats-compatibility, Compatible Formats>> table. There is
some additional work underway to make sure the compatibility language
makes sense for all of uncompressed, compressed, and multiplanar formats
(public issue 763).
* Cleanup `VK_NV_ray_tracing` language (public issues 858, 859).
Internal Issues:
* Specify in <<shaders-invocationgroups, Invocation and Derivative
Groups>> and <<textures-output-format-conversion, Texel Output Format
Conversion>> that derivative groups are quads when code:SubgroupSize >=
4 (internal issue 1390).
* Make the type of slink:VkDescriptorUpdateTemplateCreateInfo::pNext
`const` following pattern for the other stext:Vk*CreateInfo structures
(internal issue 1459).
* Specify that flink:vkCmdClearAttachments executes as a drawing command,
rather than a transfer command (internal issue 1463).
* Update `VK_NV_ray_tracing` to use code:InstanceId instead of
code:InstanceIndex.
New Extensions:
* `VK_KHR_swapchain_mutable_format`
* `VK_EXT_fragment_density_map`
* Update release number to 93.
Public Issues:
* Add spec language for ename:VK_INDEX_TYPE_NONE_NV and fix up
slink:VkAccelerationStructureTypeNV (public issue 848).
* Add missing suffix in description of slink:VkSubpassDescription2KHR
parameters (public pull request 851).
* Fix miscellaneous typos (public pull request 855).
* Add driver ID for Pastel (public pull request 856).
* Add missing include directive for slink:VkMemoryWin32HandlePropertiesKHR
implicit valid usage statements (public pull request 857).
Internal Issues:
* Restrict the storage classes permitted for SPIR-V atomics to what is
actually supported, in the <<spirvenv-module-validation, Validation
Rules within a Module>> section (internal issue 1123).
* Add a missing Valid Usage statement to slink:VkRenderPassCreateInfo for
the case pname:stencilLoadOp == ename:VK_LOAD_OP_CLEAR, pname:layout ==
ename:VK_IMAGE_LAYOUT_DEPTH_STENCIL_READ_ONLY_OPTIMAL (internal issue
1408).
* Modify optimize-pdf script and Makefile to retain non-optimized original
PDF on errors (internal issue 1435).
* Add <<spirvenv-module-validation, SPIR-V validation rules>> stating that
only the listed code:BuiltIn decorations are permitted, and only when
relevante features and extensions are enabled (internal issue 1449).
* Remove some duplicated Valid Usage IDs created via cut & paste error
(internal issue 1455).
* Build HTML output for extension reference pages (internal issue 1461).
** Improve genRef.py handling of aliases defined inside other refpages.
** Emit aliases in pygenerator.py.
** Add XML noautovalidity flag for VkRenderPassCreateFlags until there
are some corresponding FlagBits defined.
** Corrected types= attribute on some refpage blocks to 'flags'
** Added refpage blocks for some missing types detected by CI tests.
* Fixed many Valid Usage statement issues in slink:VkRenderPassCreateInfo,
slink:VkSubpassDescription, slink:VkSubpassDescription2KHR,
slink:VkSubpassDependency2KHR, flink:vkCmdBeginRenderPass,
flink:vkCmdBeginRenderPass2KHR, and slink:VkRenderPassBeginInfo
discovered while adding `VK_KHR_create_renderpass2` to the validation
layers.
New Extensions:
* `VK_EXT_scalar_block_layout`
* `VK_EXT_separate_stencil_usage`
* Update release number to 92.
Public Issues:
* Move and modify valid usage statements dealing with pname:aspectMask in
flink:vkCmdClearColorImage, flink:vkCmdClearDepthStencilImage, and
slink:VkClearAttachment, so they are in places where all necessary
information is available (public issue 529).
* Fix math markup in <<textures-texel-anisotropic-filtering, Texel
Anisotropic Filtering>> (public pull request 840).
* Fix misspellings (public pull request 845).
Internal Issues:
* Add installation instructions and a Makefile "`chunked`" target for
chunked HTML generation (internal issue 1352).
* Fix pipeline mesh diagram style; also fix a minor bug in the classic
pipeline diagram where vertex/index buffers wrongly fed into the vertex
shader (internal issue 1436).
* Make asciidoctor ERROR output raise an error, and don't suppress
executed command output from CI make invocation (internal issue 1454).
* Minor typo fixes and clarifications for `VK_NV_raytracing`.
* Cleanup extension-specific properties
** Remove duplicated documentation for pname:maxDiscardRectangles,
pname:pointClippingBehavior, and pname:maxVertexAttribDivisor (they
shouldn't be documented with the other members of
slink:VkPhysicalDeviceLimits at all).
** Remove duplicate anchor for pname:maxVertexAttribDivisor
** Consistently document stext:VkPhysicalDevice<Extension>PropertiesKHR
*** Always document pname:sType/pname:pNext (was inconsistent before)
*** Always mention chaining to slink:VkPhysicalDeviceProperties2 (and not
as slink:VkPhysicalDeviceProperties2KHR)
*** Always include Valid Usage statements last
* Update Makefile 'checklinks' target and associated scripts, and fix
markup problems identified by checkLinks.py, so that we can rely on the
checklinks script as part of Gitlab CI.
* Update release number to 91.
Public Issues:
* Update Ubuntu subsystem build instructions in `BUILD.adoc` (public pull
request 624).
* Delete the `VK_KHR_mir_surface` extension from the Specification and
XML, due to EOL of the only driver known to have supported it, and
near-EOL of Mir itself (public issue 814).
* Fix options for some figures that were using old ones (public pull
request 841).
* Fix various accidentally repeated words (public pull request 843).
* Use `time.process_time()`, introduced in Python 3.3, in the scripts
instead of `time.clock()`, which will be removed in Python 3.8 (public
pull request 844).
Internal Issues:
* Update valid usage statements for
`VK_ANDROID_external_memory_android_hardware_buffer` in
slink:VkMemoryAllocateInfo,
slink:VkImportAndroidHardwareBufferInfoANDROID, and
flink:vkGetAndroidHardwareBufferPropertiesANDROID to actually be
verifiable (internal issue 1419).
* Update valid usage statements for
`VK_ANDROID_external_memory_android_hardware_buffer` in
slink:VkMemoryAllocateInfo, slink:VkImageCreateInfo, and
slink:VkImageViewCreateInfo to move valid usage statements in
doubly-nested bullet points up one level, accomodating limitations of
the valid usage extraction script that creates `validusage.json`
(internal issue 1434).
* Fix typo etext:VK_ACCESS_SHADING_RATE_IMAGE_BIT_NV to the correct
ename:VK_ACCESS_SHADING_RATE_IMAGE_READ_BIT_NV.
* Add missing etext:VK_STRUCTURE_TYPE_* tokens to appendices for
extensions missing them.
New Extensions:
* `VK_AMD_memory_overallocation_behavior`
* `VK_NV_ray_tracing`, replacing `VK_NVX_raytracing`
