acpi-cpufreq device not found?


This is a rather odd problem. Whenever I try and enable cpu frequency scaling, I get the following:

Code:
[root@localhost grub]# modprobe acpi-cpufreq
FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.18-1.2798.fc6/kernel/arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.ko): No such device
I'm pretty much stumped. I'm runing an Intel Pentium-M ULV 1.0GHz i686 processor. However, some quality time with the terminal and yum shows that the "kernel.i386" version is installed. Should I change to the i686 version? Is there some kmod package I need? My kernel version is 2.6.18, so I don't think there's a issue with that.

Thanks for any help.

You need to be sure your processor supports it. According to:

http://ubuntu.wordpress.com/2005/11/...uency-scaling/

you can have a look at:

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies

and

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors

which gives feedback from the processor hardware as to what it supports and doesn't.

Have you tried

# modprobe cpufreq_ondemand

instead? This is the module that governs my cpu frequency in FC6.

Regards
Chris

I know that my CPU supports it since it worked all the time in Gentoo and Kubuntu.

I tried modprobe cpufreq_ondemand, and that worked without error messages, however, the CPU frequency scaling applet for Gnome doesn't seem to work still (which is how I want to control the frequency scaling, since that'd be easier - I'm trying to keep my system more GTD, rather than my personal Linux playground).

Thanks for your help though. I'm sure I'm getting closer to the solution with your suggestion of cpufreq_ondemand

Yes, you need the 686 kernel. I had the exact same problem with FC6 - it, by default, installed the 586 kernel. Deleted that, and without reboot, installed the 686 kernel. Works with reboot.

If you want to know if you have the i586 or i586 kernel installed, in a console:

Code:
rpm -q kernel --qf '%{ARCH}\n'
If you want to replace the 586kernel with the i686 kernel, in a console

Code:
su -
yumdownloader kernel-2.6.18-1.2798.fc6.i686
rpm -Uvh --replacefiles --replacepkgs kernel-2.6.18-1.2798.fc6.i686.rpm

I found better luck with

Code:
# yum install kernel-2.6.18-1.2798.fc6.i686
Installing now, going to see how it works.

Switching to the i686 kernel worked.

A small hitch for future reference: the i586 kernel that was installed was slightly more up to date than the replacement i686 kernel. After it finished downloading (btw: an easier download would be "$ yum kernel.i686") it quit because the installed was more recent than the replacement. Going to /var/cache/yum/core/packages and then using "$ rpm --force --install kernel-{VERSION}.{ARCH}.rpm" worked.

Thanks for the help! I really appreciate it!
