Description

This extension adds a new FormatFeatureFlagBits2KHR 64bits format feature flag type to extend the existing FormatFeatureFlagBits which is limited to 31 flags. At the time of this writing 29 bits of FormatFeatureFlagBits are already used.

Because FormatProperties2 is already defined to extend the Vulkan 1.0 getPhysicalDeviceFormatProperties entry point, this extension defines a new FormatProperties3KHR to extend the FormatProperties.

On top of replicating all the bits from FormatFeatureFlagBits, FormatFeatureFlagBits2KHR adds the following bits :

Prior to version 2 of this extension, implementations exposing the shaderStorageImageReadWithoutFormat and shaderStorageImageWriteWithoutFormat features may not report FORMAT_FEATURE_2_STORAGE_READ_WITHOUT_FORMAT_BIT_KHR and FORMAT_FEATURE_2_STORAGE_WRITE_WITHOUT_FORMAT_BIT_KHR in FormatProperties3KHR::bufferFeatures. Despite this, buffer reads/writes are supported as intended by the original features.

New Structures

New Enums

New Bitmasks

New Enum Constants

Promotion to Vulkan 1.3

Functionality in this extension is included in core Vulkan 1.3, with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.
