"Powertop / turbostat -d show no GFX stats reported." Literally, as in no page showing the GFXWatt and rc6 residency? Or just that they don't vary. If the former, that is the /sys/class/drm/cardN/power directory not being exposed. Shouldn't be affected by gvt at all (but yes, it is pointless to build it - but it should just not even initialise on your hw and not impact runtime at all). However, the final figures still show no pc7 even though cpu + gpu is idle. That usually takes i915.enable_fbc=1 as well.</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>
