Phoronix: Mesa 23.3 Lands Support For Rusticl On Zink To Have OpenCL Atop Vulkan Drivers

Merged for this quarter's Mesa 23.3 release is the ability to have the Rusticl Rust-written OpenCL driver running atop Zink, the Gallium3D driver known for OpenGL-on-Vulkan. With Rusticl on Zink this now means getting this OpenCL 3.0 driver working atop Vulkan hardware drivers...

Wait a minute.
If Rusticl works on top of Zink, then Compute Shaders work on top of Zink.

Which basically means that Zink is the de-facto multi-platform, multi-vendor Compute Language provider.

Rusticl doesn't even work on my Polaris. Clinfo shows exactly zero devices.

Turtle all the way down! Bring on the turtles I say, bring on the turtles...

I think RustiCL isn't enabled by default on any platform yet. Try setting RUSTICL_ENABLE=radeonsi to enable it. (I think on Intel you also need to set RUSTICL_ENABLE=iris too for example

It's hidden behind an environmental variable.

Here (Debian sid) both Clover and rusticl are detected, regardless if environmental flag set or not, just their order is reversed:

Rusticle in Zink with Vulkan

Sounds like a Clue guess
