cpufrequtils

Deprecated in D13 Trixie. Use linux-cpupower instead.

It provides:

  • /etc/init.d/cpufrequtils - disabled by default (no file ``/etc/default/cpufrequtils``)
  • /etc/init.d/loadcpufreq - loads kernel modules
  • cpufreq-set
  • cpufreq-info
  • cpufreq-aperf

utilities to deal with the cpufreq Linux kernel feature This package contains two utilities for inspecting and setting the CPU frequency through both the sysfs and procfs CPUFreq kernel interfaces. . By default, it also enables CPUFreq at boot time if the correct CPU driver is found. 

/etc/default/cpufrequtils

change governor for all cpus

for ((i=0;i<$(nproc);i++)); do cpufreq-set -c $i -r -g powersave; done

Ansible one liner: 

(cd .. && ansible pves -i $INVENTORY -a "bash -c 'for ((i=0;i<\$(nproc);i++)); do cpufreq-set -c \$i -r -g powersave; done'" --become)
