Frequently Asked Questions
Well the name of this section is misleading - but hey - I think they are the kinds of questions which would be asked frequently!
hat is the current status?
For now, it works with my laptop, a 3000-100.
Since the 400 is absolutely the
same as the 100 (the only difference is that the 400 has a CD-RW instead
of a CD-R...), it will work on both of these laptops.
How do I use this kernel module?
echo -n 50 65 > /proc/toshiba3k/state
will set the trip points for your fan to 50° - 60°. This means
that it will turn on at 65° and off once it reaches 50°. Change
these settings as you wish.
cat /proc/toshiba3k/state will tell you the
current trip points as well as if the fan is currently off or on (for
the hearing impaired :-) )
If you compiled the module with SpeedStep Support:
echo 0 > /proc/toshiba3k/cpu
permit you to be on high frequency mode.
echo 1 > /proc/toshiba3k/cpu
is for the low frequency mode.
Why can't I use the SpeedStep function with my laptop?
The 100 and 400 Models use the ICH2-M Chipset.
Dominik Brodowski also found a way to do a SpeedStep transition with
this chipset without a need to do some some calls to an undocumented
APM interface. I only needed to found the "missing link" (that
is, bus master arbitration should be disabled) to have a correct implementation.
You can also check the cpufreq webpage <http://www.advogato.org/proj/CPUFreq/>
for more details and for a working alternative for a SpeedStep support.
Note that, for other Satellite models other than the 100-400, the SpeedStep
could be easily implemeted, but it was reported to me it already worked
under ACPI (but with this "myterious" APM interface), and
I was too lazy at that time to do a correct implementation (mainly correct
values detections for the core frequencies (this one is ok) of the CPU
and for the power comsuption (not ok)) for all models.
Toshiba Satetellite 3000-601
Somebody has tried the (now obsolete) utilities at ftp://ftp.poupinou.org/
so that it work on toshiba 3000-601. This person also reported me that
it worked on AC, but not when the laptop was on battery. I don't know
why.
I hope also the module will work as expected on the toshiba 3000-601.
Is there any chance at all that this will work with
my Satellite XXX?
It is possible that it will work for all the
models of the Sattelite 3000.
I think it could also work for all toshiba laptops with a Phoenix bios.
Please contact me <ducrot@poupinou.org> if you
think that your laptop
could work with that module. I also need some feedback, so don't hesitate
to write me in all cases (success or failure).
