How to install FOSS OpenCL for AMD GPU on Debian 11 (Bullseye)

It is very easy to set up free-and-open-source OpenCL computing support if you have an AMD GPU and Debian 11:

apt install ocl-icd-libopencl1 mesa-opencl-icd

Then use clinfo (from the package clinfo) to display information about your platform.

You can now use /dev/dri and the files in /etc/OpenCL to run OpenCL applications.
