3.2.2. CPUfreq Setup

All CPUfreq drivers are built in and selected automatically, so to set up CPUfreq you just need to select a governor.
You can view which governors are available for use for a specific CPU using:
cpupower frequency-info --governors
You can then enable one of these governors on all CPUs using:
cpupower frequency-set --governor [governor]
To only enable a governor on specific cores, use -c with a range or comma-separated list of CPU numbers. For example, to enable the Userspace governor for CPUs 1-3 and 5, the command would be:
cpupower -c 1-3,5 frequency-set --governor cpufreq_userspace
