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?
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...
Regards Sam |

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.

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:

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?

It's not a hardware limitation. The driver relies on what the OEM put in the power tables as that is what was validated with the OEM. You might check to see if your OEM offers an updated bios for your system.
