Thanks for the answer. Here are the updates:
% modprobe thermal && echo OK OK
Ok.
% cpufreq-info cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006 Report errors and bugs to linux@brodo.de, please. analyzing CPU 0: no or unknown cpufreq driver is active on this CPU
% source /usr/bin/cpufreq-detect.sh
% echo $MODULE powernow-k8
% modprobe $MODULE FATAL: Error inserting powernow_k8 (/lib/modules/2.6.20-grml/kernel/arch/i386/kernel/cpu/cpufreq/powernow-k8.ko): No such device
That's bad, so powernow_k8 does not seem to support your CPU. What's inside your syslog (/var/log/syslog) when you try to load the module (modprobe powernow-k8)?
% cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor: No such file or directory
[...]
That's clear, you can't use cpufreq unless the appropriate modules are loaded.
To recap, the problems I see are:
- The thermal kernel loaded ok, but cpufreq-info still says no driver is active
- cpufreq-detect.sh successfully detected my CPU module, but modprobe return weird error "No such device".
Here are more testing/info:
% mkdir /sys/devices/system/cpu/cpu0/cpufreq mkdir: cannot create directory `/sys/devices/system/cpu/cpu0/cpufreq': Operation not permitted
sysfs does not work that way. :)
% /etc/init.d/powernowd start Starting powernowd: required sysfs objects not found!
Sure, as above -> requirements must be fulfilled first of all.
