VK_KHR_extended_flags

This extension adds a new VkFormatFeatureFlagBits4KHR format feature flag type, supporting up to 64 additional flags beyond those defined by VkFormatFeatureFlagBits2; and a new VkFormatProperties4KHR structure to extend VkFormatProperties2. The new structure does not replace format feature flag bits specified by existing commands and structures, unlike VkFormatProperties3. Instead, it adds new flags to the existing APIs. Initially, no new format flag bits are defined.

This extension also adds a new VkImageCreateFlagBits2KHR image create flag type, supporting up to 32 additional flags, and a new VkImageCreateFlags2CreateInfoKHR structure to extend VkImageCreateInfo and other commands that specify image create flag bits. The new structure duplicates image create flag bits specified by existing commands and structures, while also adding up to 32 new flags. All the existing VkImageCreateFlagBits are given corresponding VkImageCreateFlagBits2KHR bits with the same meaning. Initially, no new image create flag bits are defined.

This extension also adds a new VkImageUsageFlagBits2KHR image usage flag type, supporting up to 32 additional flags, and a new VkImageUsageFlags2CreateInfoKHR structure to extend VkImageCreateInfo and other commands that specify image usage flag bits. The new structure duplicates image usage flag bits specified by existing commands and structures, while also adding up to 32 new flags. All the existing VkImageUsageFlagBits are given corresponding VkImageUsageFlagBits2KHR bits with the same meaning. Initially, no new image usage flag bits are defined.

The extension is infrastructure used because the API is running out of available bits in the VkFormatFeatureFlagBits2 and VkImageUsageFlagBits types, and will soon thereafter run out of bits in VkImageCreateFlagBits.

Finally, this extension adds all the same 64-bit flag types first introduced by VK_KHR_maintenance5. This will allow API variants like Vulkan SC to support the extended flags without requiring other, unrelated functionality of VK_KHR_maintenance5.
