Oh I see, I didn't realize that, I thought it was about as dynamic as ondemand.

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. > Thanks for the testing, the intel_pstate change will be queued up for 4.12 > in the next couple of days. 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! -- You are receiving this mail because: You are the assignee for the bug.
