cpufreq in dothan

[Guest]

Hi everyone,
I've installed the Fedora Core 2 in my T42 2378fvu. With the up2date I've upgrade all the
packages. The current version of the kernel installed is the 2.6.7-1.494.2.2
The problem is that cpufreq is not running fine. The laptops woks always at 1.7ghz
To arrange that i've tried to follow the instructions of

http://pmw.org/~gardnerj/Thinkpad/Install.html

and

http://www.fedoraforum.org/forum/showth ... ht=cpufreq

but the gnome-cpufreq-applet. gives me the following message:

There is no cpufreq support in your system, needed to use CPU Frequency Scaling Monitor. If your system already supports cpufreq, chek whether /sys or /proc files systems are mounted.


However I installed the cpufreq with the apt-get. Do you know what happens?

Another question, do you know where to find the rpm for the NTFS support for the kernel
2.6.7-1.494.2.2?.

Regards!

I was experiencing the same problem with my dothan until I came across the following page and followed the instructions there...

... now everything works fine
(note that I specified that speedstep-centrino not be compiled in, but built as a kernel module).

Hope this helps.

Thanks so much for the link! I think it's what i was looking for. I'm scary with the kernel compilation because i've never done that, is there some way to do it easily?

Regards!

it worked!!!
to compile the kernel I followed the insitructions of the first linke that i posted above, and know following the instructions of the spaniard guy of your link the cpufreq varies in a range of 6 speeds. Thanks egain!
A question, the variation of the the dothan is not in smaller steps in Windows XP? I've the impression that in windows is possible is possilble to go below 600Mhz (very useful to save battery).

glad to hear that it worked

You're right, the frequency goes much lower in WinXP (around 197MHz is the lowest I've seen on my Pentium M 745 1.8GHz) than it does in Linux.

I glanced through the code (/usr/src/linux/arch/i386/kernel/cpu/cpufreq/speedstep-centrino.c) and it looks like it was written with speedstep info valid up to the 1.7GHz Pentium M (Someone correct me if I'm wrong).
