Change log for December 19, 2023 Vulkan 1.3.274 spec update:

Github Issues

    allow pname:pMultisampleState to be optional (internal MR 6312).

    ename:VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER (internal MR 6318).
  * Specify alignment requirement VUs for slink:VkSparseMemoryBind

  * Clarify slink:VkDescriptorSetLayoutBinding::pname:stageFlags VU
    (internal MR 6333).
  * Fix some slink:VkGraphicsPipelineCreateInfo VUs to read properly without
    some related extensions enabled in the build (internal MR 6335).
  * Fix code:OutputTriangles -> code:OutputTrianglesNV in the description of
    code:PrimitiveIndicesNV (internal MR 6338).
  * Add capture replay VUs to slink:VkAccelerationStructureCreateInfoKHR to
    ensure that the acceleration structure and buffer are identical and have
    the same addresses (internal MR 6351).

New Extensions

  * VK_KHR_maintenance6
  * Video Encode Extensions
  ** VK_KHR_video_encode_queue (was provisional KHR)
  ** VK_KHR_video_encode_h264 (promoted from provisional EXT)

+
+=== Description
+
+apiext:VK_KHR_maintenance6 adds a collection of minor features, none of
+which would warrant an entire extension of their own.
+
+The new features are as follows:
+
+  * slink:VkBindMemoryStatusKHR may be included in the pname:pNext chain of
+    slink:VkBindBufferMemoryInfo and slink:VkBindImageMemoryInfo, allowing
+    applications to identify individual resources for which memory binding
+    failed during calls to flink:vkBindBufferMemory2 and
+    flink:vkBindImageMemory2.
+  * A new property pname:fragmentShadingRateClampCombinerInputs to indicate
+    if an implementation clamps the inputs to fragment shading rate combiner
+    operations.
+  * dlink:VK_NULL_HANDLE is allowed to be used when binding an index buffer,
+    instead of a valid slink:VkBuffer handle.
+    When the <<features-nullDescriptor, pname:nullDescriptor>> feature is
+    enabled, every index fetched results in a value of zero.
+  * A new property pname:maxCombinedImageSamplerDescriptorCount to indicate
+    the maximum number of descriptors needed for any of the
+    <<formats-requiring-sampler-ycbcr-conversion, formats that require a
+    sampler {YCbCr} conversion>> supported by the implementation.
+  * A new property pname:blockTexelViewCompatibleMultipleLayers indicating
+    whether ename:VK_IMAGE_CREATE_BLOCK_TEXEL_VIEW_COMPATIBLE_BIT is allowed
+    to be used with pname:layerCount > 1
+  * pname:pNext extensible *2 versions of all descriptor binding commands.

-1) Why is there no `VK_PIPELINE_STAGE_VIDEO_ENCODE_BIT_KHR`?
-
-*RESOLVED*: This extension requires `VK_KHR_synchronization2` because the
-new access flags introduced did not fit in the 32-bit enum
-`VkAccessFlagBits`.
-Accordingly, all new pipeline stage and access flags have been added to the
-corresponding 64-bit enum and no new flags have been added to the legacy
-32-bit enums.
-While the new pipeline stage flag introduced uses bit #27 which would also
-fit in the legacy `VkPipelineStageFlagBits` enum, there is no real benefit
-to include it.
-Instead the bit is marked reserved.
