Powernow K7 question

Powernow K7 question

[Davin Carter]

I have a mobile athlon 2400+ cpu on a shuttle AK32-E motherboard running
Suse 9.0.  
The module powernow-k7 is loaded.
The kernel messages when loading the module are:
Powernow:  AMD K7 CPU detected.
Powernow: PowerNOW? Technology present.  Can Scale: frequency and voltage.

I do not see any cpu information in /proc/cpufreq or /proc/sys/cpu/0/*.  

I also looked through this list and found a utility
http://poup.poupinou.org/cpufreq/powernow-k7/dump_psb.c
<http://poup.poupinou.org/cpufreq/powernow-k7/dump_psb.c> , which should
dump some table data.  Running the utility produced no output.  
Is powernow-k7 missing some data that should be supplied by the motherboard?
Do you know of a good link for this?
Also, is it possible to change the core voltage with the powernow module
without any table data?. The current core voltage is not correct for the
cpu.  The motherboard thinks the core should be 1.55V instead of 1.35V.   I
can drop the core by 100mv in bios, but would at lease like to drop by
another 100mv.

There was a lengthy discussion about Athlon XP-M on desktop boards (in
my case, Asus A7V8X) some weeks ago - check the archives. The mainboard
needs to support at least the frequency tables for the CPU. I know of no
mainboard that does. 

What does /proc/cpuinfo say in your case? 

There are several patches to powernow-k7 that enable you to supply your own
PSB on the command line for instance. Unfortunately, the powernow
maintainers want to save the world from exploding CPUs and don't add such a
patch ;-) Contact me directly if you're interested (prepend an "h" to the
e-mail address above). 

Ciao,
