Configuration

Background

# 'governors' ('platform profiles' in tlp) are exposed by linux to manage your
# cpu-scaling/battery/etc scaling. (ex: performance, powersave, ...)
#
# use either to see available profiles:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
sudo tlp-stat -p
