> Does userland print anything relevant?
I checked if OpenCL functions return any errors. No, they do not. Difference in
output of clinfo between versions:

Tried to replace clCreateCommandQueue() with modern
clCreateCommandQueueWithProperties() without any success.
I am reluctant to upgrade to CURRENT, but I can try to cherry-pick related
linux KPI commits on top of releng/12.2 if you can say which commits are
relevant.
Btw, upgrading mesa-libs and mesa-dri, but keeping the old version of clover
seems to be an option.
