CPU frequency scaling not working

[sylvainsjc]

Hi,

Like with many others distribution, I needs to have the frequency scaling working for my CPU

With ROSA 2012 LTS, the frequency scaling isn't enabled, what should I do to make it work ?

This bug in Bugzilla http://bugs.rosalinux.ru/show_bug.cgi?id=245

[sylvainsjc]

Yes !!!

I forgot that I had already reported this problem during my first tests with ROSA

Now ROSA LTS is the main distribution on my desktop but unfortunately, this problem is still here

[philippe.roubach]

it's an old pb.
amd athlon x2 64

with mandriva 2010.2 32 bit with kernel desktop 2.6.33.7 no pb. the profile list is powersave,ondemand,conservative,users,performance
but
if you use kernel server 2.6.33.7 because you have 6 GB ram then the profile is users,perfomance.

same pb with all mib kernels nrj pae desktop

same pb with mageia kernels

Currently, I use this workaround which works with my CPU~Triple core AMD Athlon II X3 460

Under root, I've created a script called script-frequence-cpu.sh

Код: Выделить всё

[root@rosa2012lts ~]# cat script-frequence-cpu.sh 
sleep 30
modprobe powernow-k8
service cpufreq restart
[root@rosa2012lts ~]# 

Then I've added it in crontab system

[philippe.roubach]

to simply launch a driver (a module)

put a statement "powernow-k8"
in /etc/modprobe.preload file

the contents of my modeprobe.preload file for 2010.2
becareful the name powernow_k8 or powernow-k8 changes with mandriva version
*************************************************************************************
# /etc/modprobe.preload: kernel modules to load at boot time.
#
# This file should contain the names of kernel modules that are
# to be loaded at boot time, one per line. Comments begin with
# a `#', and everything on the line after them are ignored.
# this file is for module-init-tools (kernel 2.5 and above) ONLY
# for old kernel use /etc/modules

powernow_k8
******************************************************************************************

yes the powernow_k8 not launched by default is a pb since 2010.2 !

[PastorDi]

Yes, I'm so in Bagzille and writing.
Iam tested in AMD k8-k9-k10 series processors. All OK in kernel-3.0.38.

Thank you Philippe, it works by this way and it's easier than my workaround with crontab
