"No CUDA or OpenCL 1.2+ support detected for GPU slot" for AMD GPUs

[anand-bhat]

There appear to be a growing number of reports where AMD GPUs (specifically Radeon RX 5600 OEM/5600 XT/5700/5700 XT) fail to run FAH due to the error "No CUDA or OpenCL 1.2+ support detected for GPU slot".

Despite the client detecting the GPU during startup, it doesn't appear to be able to detect OpenCL.

Installing the AMD GPU drivers does not appear to address the problem. What has strangely worked in a couple of cases is installing the CUDA Toolkit.

I wonder if the CUDA detection is happening before the OpenCL and thus, causing issues instead of running both and seeing what's available 🤔

[anand-bhat]

It's very strange that this is only reported for one particular series of AMD cards, all on Windows and starting mid October. Installing CUDA hasn't helped in one case and wasn't required in another so perhaps it may not be tied to the OpenCL/ CUDA detection sequence. I'll see if there is a common FAHClient version amongst these reports.

I have the same issue with my HD 8490 (on Windows 7), and in the advanced control panel, the GPU was marked 'Disabled'. Installing the latest CUDA software and the latest AMD driver did not help.

I have a similar-looking issue: https://foldingforum.org/viewtopic.php?f=81&t=36445

This is with a Vega 64 on Linux, though, so it may be a different bug. I did try installing the CUDA libraries but it didn't help.

I have an.. adjacent? issue on Linux. I explicity installed the openCL packages but still recieve this message on boot. However, if I restart folding at home (i.e. sudo systemctl restart foldingathome.service) it magically works. Sometimes.
