Here are a few examples of adding a Vulkan extension to the specification : https://github.com/KhronosGroup/Vulkan-Docs/pull/966 https://github.com/KhronosGroup/Vulkan-Docs/pull/1001 https://github.com/KhronosGroup/Vulkan-Docs/pull/87/ You can open a Mesa MR in parallel to the extension PR and once the extension is in public release of the Vulkan spec, the Mesa MR can be merged.

[Mesa-dev] Querying Vulkan driver Options
Dear Mesa developers, I'm looking into further improving adriconf[1] as a tool to configure mesa driver options. Vulkan mesa drivers can now read their configuration options from the .drirc configuration file.
