# Cpupower
|
|
|
|
Default governor is _ondemand_ for older CPUs and kernels and _schedutil_ for new CPUs and kernels.
|
|
|
|
## TL;DR
|
|
|
|
```sh
|
|
# Install.
|
|
apt install 'linux-cpupower'
|
|
dnf install 'kernel-tools'
|
|
zypper install 'cpupower'
|
|
|
|
# List the available governors.
|
|
cpupower frequency-info --governors
|
|
cpupower -c "3-6" frequency-info --governors
|
|
cpupower --cpu "0-$(( $(nproc) - 1 ))" frequency-info --governors
|
|
|
|
# Get the current active governor.
|
|
cpupower frequency-info --policy
|
|
cpupower -c '4' frequency-info --policy
|
|
cpupower --cpu '4,5' frequency-info --policy
|
|
|
|
# Set new governors until reboot.
|
|
sudo cpupower frequency-set -g 'performance'
|
|
sudo cpupower -c '1' frequency-set --governor 'powersave'
|
|
sudo cpupower --cpu '2,4,7' frequency-set --governor 'schedutil'
|
|
|
|
# Get the current frequency of CPUs.
|
|
cpupower frequency-info -f
|
|
cpupower -c '4-7' frequency-info -fm
|
|
cpupower --cpu '2,5' frequency-info --freq --human
|
|
```
