cpufreq not loaded in amd64?
For some reason, I don't have cpufreq scaling enabled:
damon@dam-main:~$ sudo powernowd -d
PowerNow Daemon v1.00, (c) 2003-2008 John Clemens
/sys/devices/system/cpu/cpu0/cpufreq/affected_cpus: No such file or
directory
err=2Found 2 scalable units: -- 1 'CPU' per scalable unit
/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq: No such file or
directory
PowerNowd encountered and error and could not start.
Please make sure that:
- You are running a v2.6.7 kernel or later
- That you have sysfs mounted /sys
- That you have the core cpufreq and cpufreq-userspace
modules loaded into your kernel
- That you have the cpufreq driver for your cpu loaded,
(for example: powernow-k7), and that it works. Check
'dmesg' for errors.
If all of the above are true, and you still have problems,
please email the author: clemej@alum.rpi.edu

Oops, no powernow-k* listed.
root@dam-main:/home/damon# modprobe powernow-k8
FATAL: Error inserting powernow_k8
(/lib/modules/2.6.32-5-amd64/kernel/arch/x86/kernel/cpu/cpufreq/powernow-k8.ko): No such device
dmesg |grep cpu -i shows (only in part)
[ 18.891118] powernow-k8: Found 1 AMD Athlon(tm) 64 X2 Dual Core
Processor 4800+ processors (2 cpu cores) (version 2.20.00)
so after googling, I see this problem pop up, but the "newest" one is at
least a year old and I don't see a solution.
What do I need to do?
cat /etc/debian_version
squeeze/sid
root@dam-main:/home/damon# uname -a
