Coppermine, cpufreq

[Matthias Hannich <dumb@tcpa-info.org>]

Hi,

I have a laptop (Gericom Webboy) with a PIII Coppermine.
I am working on a 2.4.22-kernel (from kernel.org) and patched the 
patch-2.4.22-ac4.bz2 from Alan Cox against it.

Because of having a low battery-capacity I tried to enable cpufreq and 
ACPI-stuff in the kernel (and tried to compile them as modules as well).

If I then boot the machine, I tried the following:

$ cat /proc/cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 8
model name      : Pentium III (Coppermine)
stepping        : 6
cpu MHz         : 1000.916
cache size      : 256 KB
physical id     : 0
siblings        : 1
fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 2
wp              : yes
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge 
mca cmov pat pse36 mmx fxsr sse
bogomips        : 1998.84

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

root:/usr/src/linux-2.4.22# insmod speedstep-ich
Using /lib/modules/2.4.22-ac4-486/kernel/arch/i386/kernel/speedstep-ich.o
/lib/modules/2.4.22-ac4-486/kernel/arch/i386/kernel/speedstep-ich.o:

unresolved symbol speedstep_detect_processor
/lib/modules/2.4.22-ac4-486/kernel/arch/i386/kernel/speedstep-ich.o: 
unresolved symbol speedstep_get_freqs

and didn't saw any real frequencies.

At the moment I don't know if my cpu could handle cpufreq-controlling at 
all, but hope it. I searched the archive of this ml, but except of 
"Coppermines might cause problems, might not work..." I can't find 
helpful things.

Thanks a lot and if there is something you need to help get it running, 
or I should do or try, please tell me. (Well I tried to understand the 
stuff in Documentation/cpu-freq, but...;))

Best regards,
Matthias
