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 pNext chain of VkBindBufferMemoryInfo and VkBindImageMemoryInfo, allowing applications to identify individual resources for which memory binding failed during calls to vkBindBufferMemory2 and vkBindImageMemory2.

  • A new property fragmentShadingRateClampCombinerInputs to 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 nullDescriptor feature is enabled, every index fetched results in a value of zero.

  • A new property maxCombinedImageSamplerDescriptorCount to 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 blockTexelViewCompatibleMultipleLayers indicating whether VK_IMAGE_CREATE_BLOCK_TEXEL_VIEW_COMPATIBLE_BIT is allowed to be used with layerCount > 1

  • pNext extensible *2 versions of all descriptor binding commands.
