Oh I see, I didn't realize that, I thought it was about as dynamic as ondemand.
Then I am sorry about a wrong report!

I'll be happy to test it whenever it's ready. Since I have plenty of workaround
there's of course no sense of urgence on my end.

Yes that is what I meant, I thought scaling_governor=performance with
driver=intel_pstate would scale unlike with driver=cpufreq, I was wrong again.

Well thank you for this patch, I am happy to finally be able to use pstate :)


If you don't mind me asking here, since we talked about many different
governors, and their drivers, which one do you recommend for a desktop, that
does run games, but also other things that don't require much power. Based on
my tests I'm thinking either cpufreq's ondemand or pstate's powersave.

Thank you!
