Description
The VK_KHR_16bit_storage
extension allows use of 16-bit types in shader
input and output interfaces, and push constant blocks.
This extension introduces several new optional features which map to SPIR-V
capabilities and allow access to 16-bit data in Block
-decorated objects
in the Uniform
and the StorageBuffer
storage classes, and objects
in the PushConstant
storage class.
This extension allows 16-bit variables to be declared and used as
user-defined shader inputs and outputs but does not change location
assignment and component assignment rules.
Promotion to Vulkan 1.1
All functionality in this extension is included in core Vulkan 1.1, with the
KHR suffix omitted.
However, if Vulkan 1.1 is supported and this extension is not, the
storageBuffer16BitAccess
capability is optional.
The original type, enum and command names are still available as aliases of
the core functionality.
