Hi there,

I was wondering whether there is a possibility to use cool 'n' quiet with the Hexacore-Opteron 4180. Is the kernel already supporting powernow?

When I tried to load the module acpi_cpufreq I just get:

kvmserver:~# modprobe acpi_cpufreq
FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.32-4-pve/kernel/arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.ko): No such device

When I look at the path, shouldn't there be something like 'x64' instead of 'x86'?

Any help is appreciated!

Regards, Yves
 
Hi Udo,

thanks for the advice. Indeed I didn't, but loading the module was successfull. Frequency went from 2600000 down to 800000 with scaling governor ondemand.

Let's have a look how this will affect the vm's ;-)

Thanks a lot!
Yves
