(In reply to comment #4) > Please try the attached patches. Yay, those help ! Thanks a lot, Alex ! :-) With all three patches (attachements #93015, #103772, #103773) I get working DPM and none of the error messages above. I used the drm-next-3.17-wip kernel from yesterday with the patches applied manually (noticed you committed them just after I started the build). I think you didn't commit #93015 ? I also tried without attachment #93015 [details] [review], but I can't really explain the results. I expected to see the "*ERROR* Unknown table version 3, 1" message, but it didn't show up. Still dpm didn't work and I did get the "*ERROR* ci_upload_dpm_level_enable_mask failed" message. DPM also seems to work quite correcty, the card goes up to over 1GHz (1040MHz should be max for my card) on sclk, mclk always stays the same (but is different than without dpm): # cat /sys/kernel/debug/dri/0/radeon_pm_info power level avg sclk: 100120 mclk: 130000 Without the patches, I always got: power level avg sclk: 30000 mclk: 15000 Half-Life 2 now runs more or less constantly at 60fps with hig details and 8x MSAA :-) Metro Last Light is only at 20-30fps, but that's still great. What I don't really understand is that Metro didn't feel much slower when dpm didn't work (HL2 certainly did). I guess sclk stands for "shader clock" and mclk is for "memory clock" ? On Windows I believe I also have different memory clocks between the desktop and in games - is memory clocking not dynamic yet ?
