cpufrequtils error

Hiyas

I have followed the wikiguide about cpufrequtils and when im going to do

modprobe acpi_cpufreq

it just gives me the following error

FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.28-ARCH/kernel/arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.ko): No such device

anyone know about this and what to do?

regards

Re: cpufrequtils error

Well ... tell us more, I believe that's because that module doesn't support your cpu, try inserting other modules. That module doesn't work for my Turion X2 or Athlon 64 (although in the wiki it says most cpus should be able to be controlled with that module). Give the other modules a try.

Most modern notebooks and desktops can simply use the acpi-cpufreq driver, however other options include the p4-clockmod, powernow-k6, powernow-k7, powernow-k8, and speedstep-centrino drivers.

(Even if you have an AMD k10 CPU like Phenom X4, use the powernow-k8 driver.)

Re: cpufrequtils error

I don't have that cpu (or any Intel ones) someone with a similar cpu should be able to help you.
You may be after one of the following modules: p4-clockmod speedstep-ich speedstep-lib
Its what I have on my system .... give them a try.

Re: cpufrequtils error

acpi_cpufreq is definitely the right module for Q6600. Is something else loaded that is blocking it? Try lsmod |grep cpu and see if it returns anything to do with cpufreq. If not, maybe you need to install some acpi package?

Aye, i had to enable CPU Enhanced Halt and/or CPU EIST Function in my bios. That driver manage clock to best serve therm/power/speed requirments. That is what i can read i my bios info about those funtions.

Hope that can help you out!
