I want to enable powernowd. After i compiled it from source, when i ran
# powernowd
here are the output:
powernowd: PowerNow Daemon v1.00, (c) 2003-2008 John Clemens
/sys/devices/system/cpu/cpu0/cpufreq/affected_cpus: No such file or directory
powernowd: err=2
powernowd: Found 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.

It seems that i did not satisfy condition number 2. What should I do next?
