* Update release number to 82.
Public Issues:
* Add flink:vkDestroyPipelineLayout valid usage statement that the layout
must not have been used with command buffers still in the recording
state (public issue 730).
* Correct \<unused> tag for elink:VkResult in `vk.xml` (public merge
request 746).
Internal Issues:
* Add a valid usage statement to flink:vkQueueSubmit, and similar language
to the definitions of <<synchronization-queue-transfers-acquire, acquire
operations>> requiring that an acquire operation follow a previous
release of the same subresource (internal issue 1290).
* Add <<resources-image-format-features,Image Format Features>> and
<<resources-image-view-format-features,Image View Format Features>>
sections that precisely define the slink:VkFormatFeatures supported by
images and image views, and rewrite valid usage statements to reference
these sections instead of duplicating language (internal issue 1310).
* Reword and consolidate synchronization valid usage statements for
flink:vkCmdPipelineBarrier such that they correctly account for mutiple
possible self-dependencies (internal issue 1322).
* Change order of <<Standard sample locations>> for 2xMSAA (internal issue
1347).
* Add definitions of "`<<Correctly Rounded>>`" and "`<<ULP>>`" in the
SPIR-V environment appendix, and "`Units in the Last Place (ULP)`" in
the glossary.
New Extensions:
* `VK_NV_device_diagnostic_checkpoints`
* Update release number to 81.
Public Issues:
* Fix missing "`valid`" phrasing in some obscure cases (public pull
request 605).
* Replace improper use of cannot: referring to the implementation in the
description of the
<<features-limits-maxUpdateAfterBindDescriptorsInAllPools,
pname:maxUpdateAfterBindDescriptorsInAllPools>> limit (public pull
request 738).
* Reorder description of bits in elink:VkPipelineStageFlagBits and the
<<synchronization-pipeline-stages-supported, Supported pipeline stage
flags>> table to match their definition order (public pull request 740).
* Add description of ename:VK_BUFFER_USAGE_CONDITIONAL_RENDERING_BIT_EXT
to elink:VkBufferUsageFlagBits (public pull request 741).
* Fix value usage statement for slink:VkSubpassDependency stage mask
parameters (public pull request 742).
* Fix visible markup in registry schema document (public pull request
#745).
Internal Issues:
* Make the <<geometry-invocations, geometry shader invocation
description>> and <<shaders-geometry-execution, Geometry Shader
Execution>> descriptions consistent with other pipeline stages (internal
issue 1325).
* Mark the `VK_NV_glsl_shader` extension as deprecated.
* Adjust the per-instance vertex attribute offset formula specified by
`VK_EXT_vertex_attribute_divisor` for
slink:VkVertexInputBindingDivisorDescriptionEXT so that the interaction
between pname:firstInstance and pname:divisor matches the OpenGL
convention (internal issue 1333).
- update script to detect better structs that do not need "valid"
- update vk.xml and schema to say `noautovalidity` as a hint to the
script
- fix missing const in VkValidationFlagsEXT
- update some cases that were probably avoiding the bug
* 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.
* 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.
* 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`
associated material at the top level, vk.xml and associated material in
xml/, and generated include and source files in include/vulkan/ and
src/ext_loader/, respectively (public issue 436).
