    Just to clarify, /sys/class/drm/card0/device/power_dpm_state will always be and say 'performance' right? We cannot change it?

    Hi, I managed to get a dmesg log from the kernel after booting. I'm not sure if it'll help but here it is.

    To summarize my previous post: the patches from the drm-next-3.11-wip-5 branch work fine with my 6870 (with dpm enabled). Using the later patches with dpm enabled result in graphical artifacts all over my screen. The dmesg log I linked is from using the latest patches from the drm-next-3.11 branch.

    Programming Docs

    Will we see the corresponding programming docs for UVD and DPM as well?
    At least for those parts that have been "uncovered" with the recent code drop?

    Tested new version and performance is now OK (same as with disabled dpm) :-) Thanks!

    That is unfortunate, but you will still benefit from clock gating. What do clock frequencies matter when the GPU is clock gated and effectively running at 0 MHz?

    Heh, rechecked everyting with linux-next-20130703:
    • reclocking - works [x]
    • debugfs - works [x]
    • uvd -works [x]

    Everything is so sweet form my 6670 I can't believe it!

    Btw, I've never seen unigene heaven running so smoothly (> 30 fps).

    Thanks a lot!

    Just updated to latest drm-next kernel (07/2) (from ubuntu ppa) and everything is working just fine including being able to see radeon_pm_info.

    Code:
    [email protected]:~$ sudo cat /sys/kernel/debug/dri/0/radeon_pm_info
    uvd    vclk: 0 dclk: 0
    power level 0    sclk: 15700 mclk: 20000 vddc: 900 vddci: 0
    As soon as I refreshed I checked the radeon_pm_info again and it changed just fine:

    Code:
    [email protected]:~$ sudo cat /sys/kernel/debug/dri/0/radeon_pm_info
    uvd    vclk: 0 dclk: 0
    power level 2    sclk: 75000 mclk: 80000 vddc: 1120 vddci: 0
