[SOLVED] Set ATI DPM settings at boot

I would like to set `power_dpm_force_performance_level` to `low` at boot (and possibly `power_dpm_state` to `battery`). Is this possible?
This is to reduce noise. The card is fast enough for regular usage at the lowest level, and I'd rather jank it up if needed.

Easiest way? Install rc-local from AUR (https://aur.archlinux.org/packages/rc-local/), enable the rc-local.service then edit /etc/rc.local to include two echos:

echo low > /sys/class/drm/card0/device/power_dpm_force_performance_level
echo battery > /sys/class/drm/card0/device/power_dpm_state

...or just put the same in a file like /usr/local/sbin/radpower.sh and write your own quick oneshot service:

[Unit]
Description=Custom radeon power settings
After=network.target 

[Service]
Type=oneshot
ExecStart=/usr/local/sbin/radpower.sh
RemainAfterExit=yes
 
[Install]
WantedBy=multi-user.target

Enable that, same result etc.
