Re: acpi_processor.c - kernel 2.6.1

[christian graf <chr.graf-Mmb7MZpHnFY@public.gmane.org>]

Configure your 2.6.1 kernel 
Power management options (ACPI,..)-> ACPI
	->CPU-Frequency scaling -> and there you see all the "governors".
Include powersave, performance and set the Default CPUFreq governor to
userspace.
DOwn in the make menuconfig screen you have to choose your cpu wich fits
your system !

load the newly added modules and you should find either one of the
following options (depends on your configured modules):
echo 600000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed 
or
echo 600000 > /proc/sys/cpu/0/speed 
or
echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor 

the 600000 is just an example. check out your frequency range by:

if you have mounted your sysfs, you should see the dir (and your
frequency-range min, max):
/sys/devices/system/cpu/cpu0/cpufreq$ ls
cpuinfo_max_freq             scaling_driver    scaling_min_freq
cpuinfo_min_freq             scaling_governor  scaling_setspeed
scaling_available_governors  scaling_max_freq


	
hope this helps
