Port Xscale cpufreq to BSD

Hi,

I am trying to port XScale's DVS from Linux to NetBSD. I would
appreciate (1) if you can tell me if anyone has already done this, or
(2) what files I should pay attention to for the port. Thanks very
much

powernow-k7: changing of VID is posible, says tom...

So, I've read many things about this and one of them was thread:
    http://www.linux.org.uk/mailman/private/cpufreq/2004-June/003812.html
about "[PATCH] powernow-k7: Userspace PST for Athlon XP-M on desktop 
boards".

I know that only FID of mobile CPUs can be changed on desktop board. 
Personaly, I've modded my Barton to Mobile one but I had no time to try 
changing FID in Linux. In Window$ all worked well.

BUT !!!

Today, I've read on Tom's Hardware that there IS way to change VID on 
the fly. He says that "AMD keeps the corresponding utility under lock 
and key for security reasons."
    http://www.tomshardware.com/cpu/20041001/index.html

So, if AMD has that utility for Window$,
    http://www.tomshardware.com/cpu/20041001/athlon-underclocking-06.html
I guess it's posible to make something similar for Linux

Or, maybe, Tom just wants to raise number of hits for his site? ;)

ANNOUNCE: GNOME CPU Frequency Scaling Monitor 0.3

Hi all, 

Dominik Brodowski suggested me to announce the GNOME CPUFreq applet releases here :-)

Greetings

Application
===========

GNOME CPUFreq Applet 0.3

Description
===========

GNOME CPUFreq Applet is a CPU Frequency Scaling Monitor for GNOME Panel

Features
========

   * Support for proc or sys filesystems
   * Support for multiprocessor systems

Prerequisites
=============

   * GNOME 2 libraries
   * GNOME Panel libraries
   * GNOME-VFS libraries
   * GConf

Overview of Changes in GNOME CPUFreq Applet 0.2.1
=================================================

   * Added the possibility to change the CPU Frequency (Carlos García)
   * Improved the behavior in userspace governor and /proc interface. 
     Fixes Debian bug #273041 (Carlos García)
   * Support for new governors (Dominik Brodowski, Carlos García)
   * Not show the cpu number in the tooltip in monoprocessor systems
(Carlos García)
   * Other minor bug fixes (Carlos García)
   * New and updated translations:
   	- de (Hendrik Brandt)

Thanks to Alan Swanson, Dominik Brodowski, Marius Gedminas, etc. for bug
reporting

Additional Notes
================

The applet is now able to change the CPU frequency. To do that, a
generic command 
line tool will be installed, and the applet will use it. Since it's
needed to be root 
to change the CPU frequency, the command line tool will be installed
suid root. 
But, this default behavior could be altered by passing arguments to the
configure 
script. 

If you don't want to install the command line tool, you can use --
disable-frequency-selector
If you want to install the command line tool, but you don't want it suid
root, you can 
use --enable-suid=no

Tarballs can be downloaded from
   http://carlosgc.linups.org/files/gnome-cpufreq-applet/gnome-cpufreq-
applet-0.3.tar.gz

CVS
   http://cvs.gnome.org/viewcvs/gnome-cpufreq-applet/

GNOME CPUFreq Applet is currently being packaged as part of Debian
Unstable
   http://packages.debian.org/unstable/gnome/gnome-cpufreq-applet.html

Without the motherboard hardware supporting VID changes, this tool does
nothing. This is also what the article says: "But the motherboard, too, must
fulfill requirements in handling a pseudo-mobile processor." So - with some
boards it may work, most board don't recognize (i.e. connect) the VID pins.
If somebody has a list of boards that do use the VID pins - that would be
great.

Same story:

mymaxfid=0x00 mystartvid=0xb mynumpstates=5 
myfids=0x00,0x0a,0x06,0x04,0x12 myvids=0x0b,0x0d,0x13,0x13,0x13

I guess that my CPU can not be recognised because it's modded Barton. I 
made it 'mobile' by connecting L5 bridge on it. But, in Window$ 
everything works fine and I'm able to change multiplier on the fly.
Maybe I just use wrong mycpuid, but I've tried 0x6a0 and 0x7a0... :(

Is there any way to force powernow to work without checking of CPU?

Re: powernow-k7: changing of VID is posible, says tom...


I'm no expert here, but you may find more info using
dmesg.  Also should fsb be 100 instead of 200?  If you
have /dev/cpuid support in your kernel, I think
cpuinfo will give you the cpuid (I think so anyway)

I should say that I couldnt get this to work either,
although others on the list certainly have :).
