Totally clueless in cpufreq, cpufreqd, acpi land.


This just seems WAY too simple a concept for the great volumes of information out there on the subject, none of which actually gets me working.

I just want to set my cpu to ondemand scaling. I don't care how at this point.

Some points of total confusion:

1) what is the difference between cpufreq and cpufreqd?
2) why is it sometimes acpi-cpufreq and others acpi_cpufreq
3) where is the configuration file if I use cpufreq (i.e. not cpufreqd)?
4) should I just be using cpufreqd...how?

This is maddeningly frustrating. Please help.

Thanks.

if the ondemand governor is running, you don't need cpufreq. Those are for userspace governor.

enter the following directory:
/sys/devices/system/cpu/cpu0/cpufreq/
run "cat scaling_governor"
to see what yours is set at.
