Hi!

I don't have AMD GPUs currently, but I guess it's an upstream issue, and I'm unsure if it's already known or not, but several people have reported issues with OpenCL. At this point, I'd probably suggest to revert to 7.6.13 (aur/foldingathome?) until the next beta release and then, if the problem persists, report it upstream.

Hi,

For some reason foldingathome does not work if it does not have a freshly configured GPU slot (amdgpu, opencl-amd). Instead I get this in the log:

14:41:57:WARNING:FS00:No OpenCL 1.2+ support detected for GPU slot gpu:-1:-1.  Disabling.
14:41:57:FS00:Initialized folding slot 00: gpu:-1:-1 - DISABLED
14:41:57:ERROR:No valid folding configuration

I've noticed these two lines (in the config file at /opt/fah/config.xml) are the culprit:

    <pci-bus v='3'/>
    <pci-slot v='0'/>

Removing those, and on the next restart foldingathome will start folding on the GPU as it should. Same can be achieved by removing these options via the GUI (FAHControl), and restarting service (just removal is not enough). However, on next shutdown, foldingathome will rewrite those options into the configuration file, and subsequent starts of the service will fail detecting the slot.

Is this an upstream issue? I can not find anything similar via search. Can other opencl-amd users confirm this?

Foldingathome (stable) has other problems with the cores on the GPU, and I'm trying to determine if this client has fixes for those.

(as a sidenote, the slots automatically added to the configuration file seem to be right according to lspci; why it still fails, I have no idea)

Good job. This package gives some of us options to actually start gpu folding again. Up-voted

That fixed it, all working again. Thanks

Thank you! Could you please try the updated package? --exec-directory and --data-directory options were replaced with --chdir in beta.

Having an issue with the latest version. The error claims the dir doesn't exist which obviously isn't the case. I think this might be an upstream issue though?
