Automatic loading of module/driver powernow-k8?

#1 Postby rpeake » Wed Jan 11, 2012 8:15 am

Hello
I have cpufrequtils 007-1 installed but it does not work because the appropriate driver powernow-k8 is not autoloaded.
It can be loaded manually using 'modprobe powernow-k8'.

<<[root@X73B ron]# modprobe powernow-k8
[root@X73B ron]# cpufreq-info
cpufrequtils 007: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpufreq@vger.kernel.org, please.
analyzing CPU 0:
driver: powernow-k8
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 1000 ns.
hardware limits: 800 MHz - 1.60 GHz
available frequency steps: 1.60 GHz, 1.28 GHz, 800 MHz
available cpufreq governors: powersave, userspace, conservative, ondemand, performance
current policy: frequency should be within 800 MHz and 1.60 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 800 MHz (asserted by call to hardware).

Placing 'modules=(powernow-k8)' into etc/modules did not work. So how should it be done?
The processor is an AMD dual core E-350 APU.

Hello. Like this:

Code: Select all

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
powernow-k8
