Phoronix: Mesa's Rusticl OpenCL Driver Nearly Ready With AMD Radeon GPU Support

The Rusticl Rust-based OpenCL driver implementation that was merged last year into Mesa 22.3 has been an extremely promising effort. One of the issues though is that with the current mainline state inside Mesa has lacked support for working with AMD Radeon GPUs via the RadeonSI Gallium3D driver, but that is now coming to fruition...

There is still one more MR which needs to be merged, but we're almost there: https://gitlab.freedesktop.org/mesa/...2#note_1755422
Talking about ROCm I've managed to compile it on my Raptor CS Talos 2 ppc64le but it fails at runtime: https://github.com/RadeonOpenCompute...ime/issues/158
Rusticl on the other hand already works (at least for some workloads), but it renders black images in darktable.
Which one will enable fully working OpenCL acceleration on ppc64le first? I wouldn't bet on ROCm unfortunately.

Nice! I myself and a lot of other people are waiting for this, I know a few VS filters that can benefit nicely from rusticl

Rusticl is great. OpenCL is a shitshow on Intel too with a huge bloated toolchain and they only support OpenCL to push you into their own "one" API anyway.

OpenCL is a shitshow on Intel

Is it? I've recently tried Intel's Neo on my old Broadwell and it's twice as fast compared to their old Beignet stack. I will benchmark it against Rusticl soon.

Some are probably busted with RustCL thanks to a vendor string check bug, just as they are busted with ROCM/Mesa now:

(And IIRC this isnt is the only vs filter that uses oclutils, but I gave up and just ran it on Nvidia OpenCL...)

This is very good work! But am I the only one who, every time I read Rusticl, think of "testicle"?

No, but it actually is a thing.

A rusticle is a formation of rust similar to an icicle or stalactite in appearance that occurs deep underwater when wrought iron oxidizes. They may be familiar from underwater photographs of shipwrecks, such as the RMS Titanic and the German battleship Bismarck.

At least nnedi3cl seems to work on rusticl I hear.

You taught me something new. I thank you!
