radeon unable to set DPM state

According to https://wiki.archlinux.org/title/ATI#Dy … management you should be able to set you radeon GPU operation mode by writing to /sys/class/drm/card1/device/power_dpm_state. However if I do this even though the write succeeds the setting still is not changed.

$ cat /sys/class/drm/card1/device/power_dpm_state
performance
$ echo 'balanced' | sudo tee /sys/class/drm/card1/device/power_dpm_state
balanced
$ cat /sys/class/drm/card1/device/power_dpm_state
performance

My setup:

• System: Framework Laptop 13 (AMD edition)

• CPU: AMD Ryzed 7 7840U

• GPU: AMD Radeon 780M (integrated)
