Description

The VK_KHR_8bit_storage extension allows use of 8-bit types in uniform and storage buffers, and push constant blocks. This extension introduces several new optional features which map to SPIR-V capabilities and allow access to 8-bit data in Block-decorated objects in the Uniform and the StorageBuffer storage classes, and objects in the PushConstant storage class.

The StorageBuffer8BitAccess capability must be supported by all implementations of this extension. The other capabilities are optional.

Promotion to Vulkan 1.2

Vulkan APIs in this extension are included in core Vulkan 1.2, with the KHR suffix omitted. However, if Vulkan 1.2 is supported and this extension is not, the StorageBuffer8BitAccess capability is optional. External interactions defined by this extension, such as SPIR-V token names, retain their original names. The original Vulkan API names are still available as aliases of the core functionality.
