Thanks for your reply and thoughts.

Yes I have that mesa version of OpenCL installed. Unfortunately, this
version is too old and not recognized. I need OpenCL 1.2 at least I
think. clinfo says, among many other things:
   Device Version                                  OpenCL 1.1 Mesa 20.3.5
   Driver Version                                  20.3.5
   Device OpenCL C Version                         OpenCL C 1.1

This procedure requires downloading .deb drivers from
https://support.amd.com/en-us/download. Only distros supported are
Ubuntu 18.04.5 HWE, Ubuntu 20.04.3. They will most likely fail in Debian.

I spend some time testing this, best I got is ROCm 3.3 with only one
error (is breaks package "python" which doesn't even exist in debian).
Newer ROCm versions have many package breaks, therefore cannot be installed.

I will try this solution next.
