* 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`

|
|
When submitting work that operates on memory imported from a Direct3D 11
|
|
resource to a queue, the keyed mutex mechanism may: be used in addition to
|
|
Vulkan semaphores to synchronize the work.
|
|
Keyed mutexes are a property of a properly created shareable Direct3D 11
|
|
resource.
|
|
They can: only be used if the imported resource was created with the
|
|
etext:D3D11_RESOURCE_MISC_SHARED_KEYEDMUTEX flag.
|
|
|
|
To acquire keyed mutexes before submitted work and/or release them after,
|
|
add a slink:VkWin32KeyedMutexAcquireReleaseInfoNV structure to the
|
|
pname:pNext chain of the slink:VkSubmitInfo structure.
|
|
|
|
The sname:VkWin32KeyedMutexAcquireReleaseInfoNV structure is defined as:
|
|
|
|
include::../../api/structs/VkWin32KeyedMutexAcquireReleaseInfoNV.txt[]
|
|
|
|
* pname:acquireCount is the number of entries in the pname:pAcquireSyncs,
|
|
pname:pAcquireKeys, and pname:pAcquireTimeoutMilliseconds arrays.
|
|
* pname:pAcquireSyncs is a pointer to an array of slink:VkDeviceMemory
|
|
objects which were imported from Direct3D 11 resources.
|
|
* pname:pAcquireKeys is a pointer to an array of mutex key values to wait
|
|
for prior to beginning the submitted work.
|
|
Entries refer to the keyed mutex associated with the corresponding
|
|
entries in pname:pAcquireSyncs.
|
|
* pname:pAcquireTimeoutMilliseconds is an array of timeout values, in
|
|
millisecond units, for each acquire specified in pname:pAcquireKeys.
|
|
* pname:releaseCount is the number of entries in the pname:pReleaseSyncs
|
|
and pname:pReleaseKeys arrays.
|
|
* pname:pReleaseSyncs is a pointer to an array of slink:VkDeviceMemory
|
|
objects which were imported from Direct3D 11 resources.
|
|
* pname:pReleaseKeys is a pointer to an array of mutex key values to set
|
|
when the submitted work has completed.
|
|
Entries refer to the keyed mutex associated with the corresponding
|
|
entries in pname:pReleaseSyncs.
