"perf top" doesn't show any obvious suspects. The GPU itself is measured separately, but that only really measures the EU power, not the display or the influence of the GPU on the L3 cache ring. (I would expect the ring power to be tallied under the CPU, so it is entirely possible the GPU is causing it to run at maximum frequency and we end up blaming the CPU.) Best hope is that this is an easily identifiable kernel regression. *fingers crossed*</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
