      Code:
      module.parameter=value
      is only for builtin modules, to the best of my knowledge.
      So you would need to do something like:
      Code:
      echo "options radeon dpm=1">>/etc/modprobe.d/radeon.conf
      If you want a lower clock, see if you can use the "battery" state.
      Radeon is almost always built as a module and dpm works with the Debian stock kernels and it should work in any circumstances if radeon.dpm=1 is passed to the kernel boot options.

      This is the relevant line in dmesg to see if dpm is actually activated:

      Code:
      [    7.075704] [drm] radeon: dpm initialized
      You can see it with the following command:
      Code:
      dmesg | grep " dpm "
      BTW there is the clock utility on the other thread here, you should try it.

          effective power management with DPM?

          I have a question concerning this DPM thing:
          I think I managed to set everything up correctly on my 3.12.6 kernel (at least, so it seems).
          I have a RV710 in my laptop (mobile radeon 4570)
          DPM talks about 7 different profiles..
          but when I switch from battery - balanced - performance using this command:
          Code:
          echo (profile) > /sys/class/drm/card0/device/power_dpm_state
          and monitor the frequency information with this tool:
          Code:
          while(true) do sleep 5; cat /sys/kernel/debug/dri/64/radeon_pm_info; done
          I see no difference at all; I tried:
          - doing nothing in KDE
          - doing nothing in XFCE
          - running glxgears
          - decoding a h264 movie using mplayer and vdpau

          and for every profile, I came to the conclusion: the max performance is 680mhz core and 500mhz memory, and minimal is 220 mhz core and 250 mhz memory
          test was done on AC power

          dpm output:

              I have AMD A4-4355M APU (hate it) on Samsung NP535U3C (do not like it too...).

              I use quite recent version of kernel (3.14.7-031407-generic #201406111644 on Mint 16), Gallium 0.4 on AMD Aruba, Mesa 10.3.0-devel
              Drivers are from Xorg-Edgers PPA.

              I have installed linux-firmware so ARUBA*bin are present.

              My dmesg is quite long so i had to cut it off... alot:

                What else can i do?
                Some people reports power ussage for about 0.5%/min, while i, forcing cpu to stay at lowwest speed can get usually 0.9-1% per minute.

                Please help!

                  ----------

                  Jsollie, there is a diffrence, for example (from Your log):
                  Code:
                  [    2.667173] == power state 0 ==
[    2.667175]  ui class: none
[    2.667178]  internal class: boot 
[    2.667180]  caps: video 
[    2.667182]  uvd    vclk: 0 dclk: 0
[    2.667185]          power level 0    sclk: 68000 mclk: 50000 vddc: 1200
[    2.667186]          power level 1    sclk: 68000 mclk: 50000 vddc: 1200
[    2.667188]          power level 2    sclk: 68000 mclk: 50000 vddc: 1200
[    2.667189]  status: c r b 
[    2.667191] == power state 1 ==
[    2.667192]  ui class: performance
[    2.667194]  internal class: none
[    2.667195]  caps: single_disp video 
[    2.667198]  uvd    vclk: 0 dclk: 0
[    2.667199]          power level 0    sclk: 22000 mclk: 25000 vddc: 950
[    2.667201]          power level 1    sclk: 30000 mclk: 50000 vddc: 950
[    2.667202]          power level 2    sclk: 68000 mclk: 50000 vddc: 1200
                  at 0 (boot) Your gpu is forced to use maximum (or high) frequency at all level while on 1 (performance) it cat switch from high sclk(clock) to low (and change vddc too - voltage i suppose).

                  Regards!
