Phoronix: Mesa's Rusticl Adds cl_khr_gl_sharing For Advancing OpenGL/OpenCL Interoperability

Mesa's Rust-based OpenCL implementation "Rusticl" has added initial support for the cl_khr_gl_sharing extension for working on OpenGL and OpenCL interoperability...

This is very neat, because last time I checked DaVinci Resolve required this extension, and the only way to run it on AMD GPUs was to download amdgpu-pro drivers and hack around environment variables to force the program to use those libs, instead of regular mesa.

Davinci works well with ROCm only, no need for close sourced driver.

Given the lack of support for rocm for many models of card, this seems like a win anyway.

Not to mention Vegas Pro and Handbrake; GIMP, ImageMagick, Musemage; Blender, Houdini, Realflow; PlanetExplorers, BeamNG.drive and Leela Zero should all be able to utilize this extension and benefit on ROCM-dropped or never-supported GPUs; and on Intel GPUs which have official support dating back to 11th Gen Core.. so whichever GPU came with that.

i hope soon we will dont need rocm and clover should be remove from mesa

[andre30correia]

since rusticl dont work in my apu only clover and rocm stop working in vega apu

i hope soon we will dont need rocm and clover should be remove from mesa

ROCm supports OpenCL/HIP/HIP RT/CUDA via translator/.
Rusticl supports only OpenCL.

ILL DaVInci Resolve is the only which benefit from adding cl_khr_gl_sharing extension.
Blender have dropped OpenCL usage with 3.0 release.
ILL Handbrake have dropped OpenCL usage.

Well crap I guess I'm years behind when it comes to stuff I don't use! Oh well. I tried to guess!

Thanks for the link. This page is a reminder that compute with AMD is still a fustercluck! The amount of (hardware generations and) pain I had to go through just to get a working OpenCL stack cannot be overstated. AMD makes it really hard to support it as an alternative compute vendor. Here's hoping RustiCL will solve my issues going forward.
