SPIRV-Registry

SPIR-V is a binary intermediate language for representing graphical-shader stages and compute kernels for multiple Khronos APIs, including OpenCL, OpenGL, and Vulkan.

A complete registry of all official SPIR-V specifications is available at the Khronos SPIR-V Registry.

This Project Contains

A registry of SPIR-V extensions
Issue tracking for all SPIR-V specifications
Pull requests to add new SPIR-V extensions

Publishing new extension

To publish a new extension, please create a pull request which includes:

The extension document in the asciidoc format named following the SPV_<vendor>_<name>.asciidoc pattern. The document should be placed in the extensions/<vendor> folder.
README.md update with the link to the new extension once published

To publish a non-semantic extended instruction set,

The instruction set in the asciidoc format named following the NonSemantic.<name>.asciidoc pattern. The document should be placed in the nonsemantic folder.
README.md update with the link to the new extension once published

Please see BUILD.md for instructions to create an HTML specification for this repo.

Note: we no longer push the HTML along side the extension.
