I should give some explanation about this parameter. |
| 8 |
It enables an older power management mechanism in the kernel that |
| 9 |
gives better performance with my GPU than the newer one. |
| 10 |
|
| 11 |
With radeon.dpm=1 I can use a script in /etc/local.d/ that contains |
| 12 |
this line: |
| 13 |
|
| 14 |
echo "performance" > /sys/class/drm/card0/device/power_dpm_state |
| 15 |
|
| 16 |
Positive effect is, that desktop/window operations and also video |
| 17 |
playback are much smoother. |
| 18 |
Negative side effect is, that the power consumption of my GPU and |
| 19 |
also its temperature is a bit higher than with the default settings. |
| 20 |
|
| 21 |
If I don't use radeon.dpm=1 it is also possible to manually set |
| 22 |
a GPU scheduler: |
| 23 |
|
| 24 |
echo "profile" > /sys/class/drm/card0/device/power_method |
| 25 |
echo "high" > /sys/class/drm/card0/device/power_profile |
| 26 |
|
| 27 |
But as I already mentioned, performance isn't as good as with the |
| 28 |
older power management. |
| 29 |
|

However I checked this out many months ago. Maybe it isn't relevant |
| 31 |
anymore. |
