--- Comment #13 from Chris Wilson chris@chris-wilson.co.uk --- Frequency changes are accompanied by a tracepoint (though note we only say what we ask the hw to do, the hw is at liberty to do whatever it wants), and you can enable the tracepoints for batch submission, so if you have the time and patience to correlate them with the test you can draw pretty a graph. For something along those lines, intel-gpu-overlay.
