<pre>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.</pre>
