* 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`
* Update release number to 96.
Public Issues:
* Fix typo in `vk.xml` for `structextends` attribute of
slink:VkPhysicalDeviceShadingRateImagePropertiesNV (public PR 870).
* Fix links in optimized PDF output (public PR 879).
Internal Issues:
* Add a link to GitHub contributors in the <<credits, Other Credits>>
section (internal issue 808).
* Clarify the behavior of command aliases described in the <<versions,Core
Revisions>> and <<initialization-functionpointers, Command Function
Pointers>> sections and the registry schema document with respect to
whether they are or are not the same entry point, and what the behaviour
of the ftext:vkGet*ProcAddr commands is for each alias (internal issue
1462).
* Update slink:VkPipelineShaderStageCreateInfo valid usage statements for
writing to code:Layer and code:viewportIndex to apply to any vertex
processing stage (internal issue 1475).
* Make sparse image creation optional for Y'C~B~C~R~ formats in the
<<features-required-format-support, Required Format Support>> section
and the <<features-formats-requiring-sampler-ycbcr-conversion, Formats
requiring sampler Y'C~B~C~R~ conversion for
ename:VK_IMAGE_ASPECT_COLOR_BIT image views>> table (internal issue
1476).
* Modify the valid usage statement for
flink:vkCmdDrawIndirectByteCountEXT::pname:vertexStride to use the
pname:maxTransformFeedbackBufferDataStride limit rather than the
pname:maxVertexInputBindingStride limit, which is a better match for
transform feedback related operations (internal issue 1487).
* Changed all members of slink:VkPhysicalDevicePCIBusInfoPropertiesEXT to
have the `uint32_t` type. This is an imcompatible change to an EXT
that's very recently released; although this is against usual Vulkan WG
policy, we discussed and consider this an acceptable risk, but have
polled the mesa-dev list in case there are use cases we missed (internal
issue 1492).
* Set spec vetsion to 1 for `VK_GOOGLE_hlsl_functionality1` and
`VK_GOOGLE_decorate_string` in `vk.xml` (internal MR 2948).
* Remove redundant valid usage statement `VkImageCreateInfo-pNext-02395`
(internal MR 2950).
* Add `check_spec_links.py` script, use it in Gitlab CI, and fix many
minor markup issues discovered by the script (internal MR 2955).
* Update `BUILD.md` to the current Ruby version (2.5.3), and make some
corresponding updates to per-platform build instructions (internal MR
2956).
* Fix binding numbers and other details in
flink:vkUpdateDescriptorSetWithTemplate.txt example code blocks
(internal MR 2960).
* Remove some nautovalidity="true" in `vk.xml` for NV extensions where
it's clearly wrong (internal MR 2970).
* Update release number to 85.
Public Issues:
* Add self-dependency ename:VK_DEPENDENCY_BY_REGION_BIT valid usage
statements for slink:VkSubpassDependency(public pull request 778).
* Apply fix from pull request 742 to slink:VkSubpassDependency and
slink:VkSubpassDependency2 (public pull request 779).
* Specify the units of slink:VkBufferImageCopy::pname:bufferRowLength and
pname:bufferImageHeight as texels (public pull request 781).
* Better specify promoted parameter mapping in the
`<<VK_KHR_create_renderpass2>>` appendix (public pull request 782).
Internal Issues:
* Only include the <<fundamentals-validusage-versions, Valid Usage for
Newer Core Versions>> section in Vulkan 1.1 or later (internal issue
1381).
Other Issues:
* Clean up redundant valid usage language for the
`VK_ANDROID_external_memory_android_hardware_buffer` extension
interaction with slink:VkImageCreateInfo.
* Fix error in a flag name within valid usage statements for
slink:VkMemoryAllocateInfo.
* Clarify that memory types are not totally ordered in
slink:VkPhysicalDeviceMemoryProperties.
* For slink:VkWriteDescriptorSetInlineUniformBlockEXT, set
structextends="VkWriteDescriptorSet" in `vk.xml`, and make
slink:VkDescriptorSetLayoutBindingFlagsCreateInfoEXT::pname:pBindingFlags
optional.
* Add documentation of 'provisional' XML attribute to registry.txt.
New Extensions:
* `VK_NV_compute_shader_derivatives`
* `VK_NV_corner_sampled_image`
