<pre>I tried to change power profile of a GPU to a lower one, so that laptop won't
overheat so quickly.
I found this method on the internet and various documentations:
echo low | sudo tee /sys/class/drm/card0/device/power_profile
tee: /sys/class/drm/card0/device/power_profile: Invalid argument
However this method never worked - Invalid argument show up no matter what
value I try to give the power_profile
Even giving the already existing "default" value to the power_profile leads to
"invalid argument" error.
echo default | sudo tee /sys/class/drm/card0/device/power_profile
tee: /sys/class/drm/card0/device/power_profile: Invalid argument
I would like to know why this is happening.</pre>
