AMD 6700XT on Linux fails

Posted: Sat Jan 21, 2023 6:13 am

I'm a bit new to this so could be doing something totally wrong, but I've tried my best to debug it alone and have failed. I've tried mesa openCL drivers and the proprietary AMD ones, and the issue seems to occur on both for me. System info is as follows

Welcome to the folding support forum.

Which version of Linux are you using? The installer was created initially some years ago and not updated for the latest versions of the various distros. Depending on which you may need to add the fahclient user to one or more groups such as the "video" group. There are some write-ups on that here.

As for the drivers, make certain the default drivers are unloaded. The mesa open source drivers have never worked for folding. For an AMD Radeon RX 6700 XT your options are the AMD proprietary drivers and the ROCm open source drivers. There are older posts on how to install the ROCm drivers.

This is running under Arch Linux. I did notice on the wiki a mention of using the AMD proprietary openCL drivers would be needed, and so uninstalled the mesa ones and installed the proprietary ones. Would any configuration past that be needed? If not, then I tested with that correctly. I did also consider the video group, and my user was added to this before any of the above testing took place

You may also need to install the OpenCL developer package.

Which user did you add to the video group? Your own account or the fahclient user that should have been created by the installer to run the background process with the FAHClient portion of the F@h software? Digging into some older posts some distros also require the user to be added to the "render" group.

One o the troubleshooting methods that was used when this first came up with newer Linux distress was running FAHClient from the root account. If it works then, but not from the default account, then it is a group membership issue.

The openCL dev package from AMD was installed for all of the above tests as well.

My own user was added to the video group, and judging by the service file included (attached below) with the AUR package, the service runs as user 'fah' and is automatically added to the video group. Running it directly with the root user does not remedy the issue. As far as I can tell, the render group is unused on arch linux but for good measure I did add my user to that group and the fah user to it. No change.

With that card, you will want to use the latest ROCm OpenCL drivers from AMD.

Also check that /etc/OpenCL/vendors only contains the single .icd for the AMD driver - somethings in the FAH stack does not handle multiple .icd correctly.

You will also need to use the workaround I describe here: viewtopic.php?t=38848
