Verify [AMD GPU on Arch Linux]

Post by raooowty »

Mod note: added OS and GPU type to Subject line

Hello,

I'm oldschool user (some odd 10 years ago), now out of hibernation ready to Fold again.
I understand WUs are scarce. I get WUs for CPU, and my first WU for GFX did not seem to work somehow (that's what the log is about):
If any additional info is needed, I happily provide it.

My question is; does my setup look ready for gfx-folding?

Code: Select all

$ uname -r
5.5.11-arch1-1

Code: Select all

$ yay -Q foldingathome ocl-icd opencl-mesa mesa fahcontrol 
foldingathome 7.5.1-1
ocl-icd 2.2.12-3
opencl-mesa 19.3.4-2
mesa 19.3.4-2
fahcontrol 7.5.1-1

Here is the main log from my "best attempt" at GFX folding. When googling for error code, I retrieved necro-old-threads that all had to do with aged drivers. I cannot see how mine are.

There are some posts from recent users no setting up for Arch Linux, perhaps someone will get you pointed towards them.

In the meantime, to use your HD 7800 series cards you will need to switch to the AMD proprietary drivers and OpenCL support, the GPU folding core does not work with the open source Mesa drivers shown in your second Code block.

Thank you AmunRa, very helpful post.

Unfortunately it does not add to my attempts as of yet.

Since the time of my posting I've progressed slightly and attempted the following:

- removing opencl-mesa
- adding opencl-amd
-> this resulted in foldingathome.service no longer being able to start, with the following error:

Code: Select all

FAHClient[592]: amdgpu_device_initialize: DRM version is 2.50.0 but this driver is only compatible with 3.x.x.
- removing opencl-amd
- adding rocm-amdgpu-pro-orca (per friend recommendation: https://wiki.archlinux.org/index.php/GPGPU#AMD/ATI )
-> this resulted in foldingathome.service no longer being able to start, with the following error:

Code: Select all

FAHClient[592]: amdgpu_device_initialize: DRM version is 2.50.0 but this driver is only compatible with 3.x.x.
- removing rocm-amdgpu-pro-orca
- re:adding opencl-mesa
-> service starts again, and I can at least fold via the CPU.
