Clocking

Change clock of various components

  • Print dedicated CPU clocks:

cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

  • Set CPU governor to performance:

sudo cpupower frequency-set -g performance

  • Set CPU governor to powersave:

sudo cpupower frequency-set -g powersave

  • Print dedicated GPU clocks (first card):

sudo cat /sys/kernel/debug/dri/0/pstate

  • Reclock the dedicated GPU:

echo {{pstate}} | sudo tee /sys/kernel/debug/dri/0/pstate
