--- Comment #12 from Francesco Balestrieri francesco.balestrieri@intel.com --- (In reply to Chris Wilson from comment #11)
An idle gpu is always reported as running at the min(idle) freq. You have to be very careful in the workload you construct that it does indeed keep the gpu busy if you want to use a sampling method.
Apparently the test case uses queries, not the sampled method of metrics measurement.
No sign of a bug yet...
No disagreement there, however any further suggestion as to what to look at to figure out what is going wrong is welcome.
