Problems with scaling governors

Hello. I'm new here.

I can only see the governors "performance" and "powersave". I want to add ondemand, because my laptop is running with too high temps.

# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors 
performance powersave

# ls /lib/modules/$(uname -r)/kernel/drivers/cpufreq
acpi-cpufreq.ko.gz	    cpufreq_conservative.ko.gz	cpufreq_stats.ko.gz	 mperf.ko.gz	    pcc-cpufreq.ko.gz  speedstep-lib.ko.gz
amd_freq_sensitivity.ko.gz  cpufreq_powersave.ko.gz	cpufreq_userspace.ko.gz  p4-clockmod.ko.gz  powernow-k8.ko.gz

I don't know why the cpufreq_ondemand module is not avaible.

Welcome to Arch's forums.

Please use

code tags like this

as it makes stuff much easier to read. (Quote this post or consult the forum etiquette to see how.)

I am guessing you are using an intel CPU and that it is defaulting to the new pstate stuff. This does not use the acpi-cpufreq governors at all but manages power in a completely different way.

If your laptop is running too hot, consult the wiki for ways to reduce power consumption. The intel stuff should work better than the older method - although you can disable the default and load the acpi-cpufreq stuff if you wish.

Thank you. I checked and you were right.

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
intel_pstate

Also, thanks for replying so fast, and for being so useful!
