Description

This extension enables the FORMAT_R10X6G10X6B10X6A10X6_UNORM_4PACK16 format to be used without a sampler Y′CBCR conversion enabled.

New Structures

• Extending PhysicalDeviceFeatures2, DeviceCreateInfo:

  • PhysicalDeviceRGBA10X6FormatsFeaturesEXT

New Enum Constants

• EXT_RGBA10X6_FORMATS_EXTENSION_NAME

• EXT_RGBA10X6_FORMATS_SPEC_VERSION

• Extending StructureType:

  • STRUCTURE_TYPE_PHYSICAL_DEVICE_RGBA10X6_FORMATS_FEATURES_EXT

Issues

1) Should we reuse the existing format enumeration or introduce a new one?

RESOLVED: We reuse an existing format enumeration, FORMAT_R10X6G10X6B10X6A10X6_UNORM_4PACK16, that was previously exclusively used for YCbCr and therefore had a set of limitations related to that usage. The alternative was to introduce a new format token with exactly the same bit representation as the existing token, but without the limitations.

2) Should we only introduce FORMAT_R10X6G10X6B10X6A10X6_UNORM_4PACK16 or also 1-3 component variations?

RESOLVED: Only the 4-component format is introduced because the 1- and 2- component variations are already not exclusive to YCbCr, and the 3-component variation is not a good match for hardware capabilities.

VkPhysicalDeviceRGBA10X6FormatsFeaturesEXT - Structure describing whether rendering to VK_FORMAT_R10X6G10X6B10X6A10X6_UNORM_4PACK16 formats can be supported by an implementation

Members

This structure describes the following feature:

Description

If the PhysicalDeviceRGBA10X6FormatsFeaturesEXT structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. PhysicalDeviceRGBA10X6FormatsFeaturesEXT can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.

Fields

• formatRgba10x6WithoutYCbCrSampler :: Bool

  formatRgba10x6WithoutYCbCrSampler indicates that FORMAT_R10X6G10X6B10X6A10X6_UNORM_4PACK16 can be used with a ImageView with subresourceRange.aspectMask equal to IMAGE_ASPECT_COLOR_BIT without a sampler Y′CBCR conversion enabled.
