Radeon 7800 XT not used for folding (Fedora 41) [Solved]

Hi,
I compiled and installed the FAH client from the latest code based on the RPM build instructions:
https://github.com/FoldingAtHome/fah-cl ... ING-RPM.md
Folding with CPU cores works but I want to use my dGPU, Radeon 7800 XT, instead. It seems to be recognized but when I start folding it is not used at all. Is there a way to debug this or is there info I could provide? In "machine details" I see that my dGPU is listed as "not supported" which I find weird because it worked with FAH client v7.
Below is my machine log with my discrete GPU enabled and CPU disabled. It says "machine state fold" but it is not downloading and processing any work units.

Rocm-opencl-sdk is needed and then usermod render and video for your username. Restart the PC and you should be good

Hm, probably I'll create a new thread with the guide for all major distros when I'm home

Thanks for the quick reply!
I added my user to the groups "render" and "video". Additionally, I installed the packages "rocminfo" and "rocm-opencl" via DNF. I could not find a Fedora package for rocm-opencl-sdk. (I also found some Fedora docs:
https://fedoraproject.org/wiki/SIGs/HC)
I rebooted my machine. Both rocminfo and clinfo commands list my 7800 XT. I think that's good! However, FAH client still does not use my card for folding.
Edit: I found an AMD document stating that the integrated GPU, if one exists, should be disabled:
https://rocm.docs.amd.com/projects/inst ... applicable
I have to do that as well I guess.

Remove that rocm-opencl.
Let me get home, and I'll post you the repo name for you to grab actual working stuff

It seems I am travelling around London the whole night today...
Here is a guide. This is copy pasta from another forum comment I wrote, since I'm on the bus:
remove rocm-opencl.
add
https://repo.radeon.com/amdgpu-install/6.2.3/ to your repo list (if you know how to do it).
or
go to
https://repo.radeon.com/amdgpu-install/6.2.3/ choose your distro (probably el or rhel), click on OS version (I think 41 is based on RHEL9.4, you might figure that out, or know yourself).
Download amdgpu-install package from there. Install it, it will add above mentioned repo to your sources.
refresh them. and then install rocm-opencl-sdk
then
sudo usermod -a -G render yourlinuxusername
sudo usermod -a -G video yourlinuxusername
reboot the pc.
check clinfo output. it should show opencl platform as AMD platform and opencl device should be your GPU.
If after reboot fahclient still cannot see your gpu as supported, get rocm icd loader. That should fix it.
Once things are working, go to your software sources and remove amdgpu-install related repo, since that is known to throw a fit or two is kept as repo. It is not being updated anyways, so it was used to get ROCm repo to your system.
Also if you see ROCm 6.3.x available, do not use it, this one is for HPC market, AMD seems to think it is ok to mix HPC ROCm with consumer one...

Hey!
The user groups are already configured. I removed the rocm-opencl package, added the amdgpu-install repo and installed rocm-opencl-sdk.
Rebooted. Clinfo output was OK. Still FAH webclient listed the dGPU as unsupported and work units are not processed.
I installed OpenCL-ICD-Loader but it reported a package conflicht with ocl-icd. Now, clinfo output does not report any platform!
Thanks for your efforts, however, I'll uninstall ROCm packages completely and try to get back to a clean state and will ask in the Fedora forums for additional experience with this problem. I'll report back if I find anything.

Get the sdk back on, and copy and paste clinfo output here

Is it necessary? The client process is executed under the fah-client user account, which is already part of the render and video groups.

That never worked
sudo usermod -a -G video linuxusername
sudo usermod -a -G render linuxusername
commands were always a requirement for AMD to be able to fold. Always

Okay, good news: It worked! I have no idea what I did differently this time but getting the rocm-opencl-sdk and rebooting worked fine. I had to do nothing else. Thanks a lot!
I'm still a bit miffed that AMD drivers are far behind NVidia's when it comes to scientific computing / folding (like a 7800 XT is on par with a 4070 Super with respect to gaming / rasterization performance) but hopefully that changes in the future.

Sometimes it needs couple of reboots, it seems
Regarding compute performance, AMD has something coming, just need to have patience
Once things are in place, announcement post will be made here and across the internet on what it is and how to make it work (since I am 100% sure it will not be easier to set up as it is right now with opencl).

Oh wow!
I'm looking forward to it
