What's Been Going On With CPUFreq & The Scheduler

[Licaon]

Sounds interesting. Is there a way to switch to schedutil from the kernel boot parameters instead of recompiling with CPU_FREQ_DEFAULT_GOV_SCHEDUTIL enabled?

You have a 4.7 kernel and it has the sched available?

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors

Then

echo schedutil | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

Thanks PuckPoltergeist & Licaon. I do have a 4.7 kernel with CONFIG_CPU_FREQ_GOV_SCHEDUTIL=m but echoing schedutil in scaling_governor returns "Invalid argument". Perhaps because it can't be built as a module, so I'll have to recompile anyway https://lkml.org/lkml/2016/8/19/427

Doesn't modprobing cpufreq_schedutil do the trick? Anyway, it worked out of the box on my Arch install.

Loaded and verified with lsmod, but still unavailable... since I'm also on Arch I'm perplexed, but I'm probably doing something wrong...

No messages in dmesg/journald?

halo9en if you have Intel you need disable Intel_pstate first
Intel_pstate=disable (or disabled) in boot opts should work.

Loading the module is also enough to make it work here. And I like it

Ah, thanks for saving me a headache!

I modprobed the module and switched the scheduler with cpupower and it immediately froze my computer :/

And you are nor using Con's BFS?
