## Description

On some implementations, setting the VK_IMAGE_CREATE_MUTABLE_FORMAT_BIT on image creation can cause access to that image to perform worse than an equivalent image created without VK_IMAGE_CREATE_MUTABLE_FORMAT_BIT because the implementation does not know what view formats will be paired with the image.

This extension allows an application to provide the list of all formats that can be used with an image when it is created. The implementation may then be able to create a more efficient image that supports the subset of formats required by the application without having to support all formats in the format compatibility class of the image format.

## Promotion to Vulkan 1.2

All functionality in this extension is included in core Vulkan 1.2, with the KHR suffix omitted. The original type, enum, and command names are still available as aliases of the core functionality.

## New Structures

- Extending VkImageCreateInfo, VkSwapchainCreateInfoKHR, VkPhysicalDeviceImageFormatInfo2:

  - VkImageFormatListCreateInfoKHR

## New Enum Constants

- `VK_KHR_IMAGE_FORMAT_LIST_EXTENSION_NAME`

- `VK_KHR_IMAGE_FORMAT_LIST_SPEC_VERSION`

- Extending VkStructureType:

  - VK_STRUCTURE_TYPE_IMAGE_FORMAT_LIST_CREATE_INFO_KHR
