I can only state, that by setting radeon.dpm=1 I get 60 FPS in e.g. Portal 2 and without I'm at 15 FPS max. As written in comment #0, I've built your drm-next-3.17-rebased-on-fixes branch, my top commit is commit fa783807977da98da35590fd1d5efdfd4f33fd59 Author: Christian K?nig <christian.koenig at amd.com> Date: Mon Jul 28 13:30:12 2014 +0200 drm/radeon: allow userptr write access under certain conditions It needs to be anonymous memory (no file mappings) and we are requried to install an MMU notifier. Signed-off-by: Christian K?nig <christian.koenig at amd.com> Signed-off-by: Alex Deucher <alexander.deucher at amd.com> I even went through several reboots, switching between "with radeon.dpm=1" and without. All showed the same result. Let me know, if there is something else, I can do to assist in debugging this. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
