That should address this. I haven't checked yet this bug closer, but note that RC6/RPS is not enabled on BDW on current -nightly, I'm not sure if it's by overlook or on purpose. At least intel_disable_gt_powersave() is broken on BDW, since it'll try to disable RC6/RPS when it wasn't enabled in the first place. I posted a fix for this issue: <a href="http://lists.freedesktop.org/archives/intel-gfx/2014-April/043695.html">http://lists.freedesktop.org/archives/intel-gfx/2014-April/043695.html</a> As Daniel mentioned, in the same patchset there is also a patch to disable RPM until RC6/RPS is setup, but I'm not sure how that can make a difference on BDW, since we never enabled RC6/RPS there.</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> </ul> </body> </html>
