Description
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:
-
VkBindMemoryStatusKHR may be included in the
pNextchain of VkBindBufferMemoryInfo and VkBindImageMemoryInfo, allowing applications to identify individual resources for which memory binding failed during calls to vkBindBufferMemory2 and vkBindImageMemory2. -
A new property
fragmentShadingRateClampCombinerInputsto indicate if an implementation clamps the inputs to fragment shading rate combiner operations. -
VK_NULL_HANDLE is allowed to be used when binding an index buffer, instead of a valid VkBuffer handle. When the
nullDescriptorfeature is enabled, every index fetched results in a value of zero. -
A new property
maxCombinedImageSamplerDescriptorCountto indicate the maximum number of descriptors needed for any of the formats that require a sampler Y′CBCR conversion supported by the implementation. -
A new property
blockTexelViewCompatibleMultipleLayersindicating whether VK_IMAGE_CREATE_BLOCK_TEXEL_VIEW_COMPATIBLE_BIT is allowed to be used withlayerCount> 1 -
pNextextensible *2 versions of all descriptor binding commands.

Promotion to Vulkan 1.4
Functionality in this extension is included in core Vulkan 1.4 with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.
