I’m trying to set GPU performance to high by the command
sudo echo high > /sys/class/drm/card0/device/power_dpm_force_performance_level
But I’m getting the error
<w> fish: An error while redirecting the file sys/class/drm/card0/device/power_dpm_force_performance_level open: permission denied
Any idea what I’m doing wrong?
I followed this guide to know about this step

I’m on AMD stoney graphics processor and AMD A6-9220 R4 processor
