Hi,
thanks for the explanation. Do you know if this is a hardware limitation, or if an updated version of the driver will come some day?
Regards, Sam

Hi,
thanks for your reply. Here is the dmesg.
Let me know if you need further testing.
As I suspected, on your system all the performance levels are the same:
[ 8.961675] == power state 0 == [ 8.961677] ui class: none [ 8.961679] internal class: boot [ 8.961682] caps: video [ 8.961684] uvd vclk: 0 dclk: 0 [ 8.961686] power level 0 sclk: 45000 mclk: 50000 vddc: 950 [ 8.961688] power level 1 sclk: 45000 mclk: 50000 vddc: 950 [ 8.961690] power level 2 sclk: 45000 mclk: 50000 vddc: 950 [ 8.961691] status: c r b [ 8.961695] == power state 1 == [ 8.961696] ui class: performance [ 8.961698] internal class: none [ 8.961700] caps: video [ 8.961703] uvd vclk: 0 dclk: 0 [ 8.961704] power level 0 sclk: 45000 mclk: 50000 vddc: 950 [ 8.961706] power level 1 sclk: 45000 mclk: 50000 vddc: 950 [ 8.961708] power level 2 sclk: 45000 mclk: 50000 vddc: 950 [ 8.961709] status:
So there is no dynamic switching supported on your system.

Hi,
I was testing 3.11-rc4 with and without radeon.dpm=1 and I expected some results, either in performance or in power consumption, but I do not notice any change... Should I worry? Or do you want me to do any specific test?
Please attach your dmesg output. Some early rv6xx cards had identical performance levels in all power states so they didn't actually support dynamic clock switching.

I have an ATI Mobility HD2400 (RV610).
cat /sys/class/drm/card0/device/power_dpm_state balanced
dmesg: radeon: dpm initialized
No specific error in dmesg...
