how to switch cpu scaling mode of TLP with cli command ?

when I change TLP mode, I need to change /etc/tlp.conf:

#CPU_SCALING_GOVERNOR_ON_AC=powersave

CPU_SCALING_GOVERNOR_ON_AC=performance

then, restart tlp service.

is there any way using cli command to switch it ?

Re: how to switch cpu scaling mode of TLP with cli command ?

First of all: the correct way to apply changed TLP settings is

sudo tlp start

Refer to the FAQ.

Now to your question: a temporary change of settings without adjusting the configuration file is possible as follows:

sudo tlp start -- CPU_SCALING_GOVERNOR_ON_AC=performance

After the '--' you can also enter several parameters separated by blanks.

This is actually a testing API, but it can also be used generally. However, the change only lasts until the next power source change or reboot.
