Ha, so evidently there is some issue between the way the current client, and the Ubuntu version of the openCL drivers, are identifying compatible openCL GPUs. This looks exactly like the issue that [email protected] has with openCL on AMD.

I don't have this issue on my systems, but they are all running Arch. These are the portions of the AMDGPU-Pro Ubuntu driver that I use:
  • opencl-amdgpu-pro-icd_driverVersion_amd64.deb
  • opencl-orca-amdgpu-pro-icd_driverVersion_amd64.deb
  • libdrm-amdgpu-amdgpu1_2.4.95-driverVersion_amd64.deb
In addition to those packages from the Ubuntu driver the only other things needed is to get the openCL libraries added/linked in the correct locations, the standard libdrm from Mesa, and the Open source OpenCL ICD loader (ocl-icd). Here is a link to the package for opencl-amd from the AUR on Arch. https://www.archlinux.org/packages/e...86_64/ocl-icd/ You can see what it is bringing in from the Ubuntu driver if you click "View PKGBUILD" under "Package Actions".



I haven't tried it yet, but it replicating this should be fairly straight forward on Debian based distros without using all of the additional cruft from the AMDGPU-Pro stack.

Heh, ironically, I had already tried everything you said. I had manually linked all the libraries because the paths weren't correct (x86_64-linux-gnu instead of lib64, I think). Installing opencl-amd didn't work for me either, regardless which kernel I tried it on. The ICD loader wasn't necessary for my last try which got it working.
