Hi!

I have an Athlon XP2000+ and I want to make it possible to lower the
freq in software.

I installed the 2.4.22 kernel with ac4 patch and enabled:

[*] CPU Frequency scaling
[*]  CPU frequency table helpers
--- CPUFreq governors
[*]  "userspace" for userspace frequency scaling
--- CPUFreq processor drivers
<*>  AMD Mobile Athlon/Duron K7 PowerNow! 

The kernel boots fine but when I do:

# cat /proc/cpufreq 
   minimum CPU frequency  -  maximum CPU frequency  -  policy

Shouldn't say some frequencys like?

        minimum CPU frequency  -  maximum CPU frequency  -  policy
CPU  0       500000 kHz ( 41 %)  -    1200000 kHz (100 %)  -  performance


Info about my cpu:

# cat /proc/cpuinfo

bogomips        : 2968.78

(Currently it's under clocked but I have tested with it at 2000+ mode)


Have I missed something in the kernel?

Please help.

Fredrik
