I’d like to set my laptop to use the performance governor but it’s not installed on my laptop.

How do I get cpufreq_performance.ko?

Thanks

Hi
You using the wrong tool to verify (as root user);

To check the available governors;


cpupower frequency-info

However, have a read of the governors and why they are set…
https://www.kernel.org/doc/Documentation/cpu-freq/governors.txt

3

It is built in kernel. “zgrep CPU_FREQ_GOV /proc/config.gz”.

Thank you for clarifying the why
