Howto get CPU frequency scaling to work in 2.xx

[HairyWill]

Nice idea. I'm amazed that no one has done it before it seems so obvious.

You might want to consider offering --performance as an option as well, this doesn't require a module to be loaded.

Localization too.
The \n in your localization string doesn't create a newline on the terminal. This seems to work for me
*) echo $l_usage | sed 's/\\n/\n/g';;

It would also be nice to get a message at the end confirming that something had been done. Maybe something like

cpu scaling set
scaling govenor: ondemand
CPU frequency: 800MHz

excellent

Very much thank you Will!!!
I do it.
And I want made GUI...

I use the "powersave" governor by default, but created a script that switches between powersave and "ondemand" (and vice versa), then set up a keyboard shortcut to run it...

I use powernowd, no need for anything else.

And where you can find pet ?

Why ruin a commandline program with a GUI.

The package manager includes a pet for gtkdialog-DOC which has examples for many of the widgets available. These can be written using a simple shell script.

Yess... I made GUI-script.
And its contain script cpu_power_save_eee directly for ASUS eeePC, that use module p4-clockmod...

This script use some script from Xubuntu that auto find needed cpu module, but it not find anymore for ASUS eeePC CPU
Maybe I use old version?

And don't work switching to perfomance mode (from another mode).
Because don't work this command:
echo perfomance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

Well done, works well for me

Good idea to make an autodetect script, Kazm.

Because don't work this command:
echo perfomance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

Correct spelling is performance (with two r), and it does work on my laptop. It's also the default mode in Puppy, as one can verify (e.g. after fresh live-CD boot with pfix=ram) with

Code: Select all

cd /sys/devices/system/cpu/cpu0/cpufreq/
cat scaling_governor

.
Anyway I much prefer the ondemand mode, for reasons explained in [url=ttp://www.murga-linux.com/puppy/viewtopic.php?t=28443]how to keep your cpu cool and you fan quiet[/url]
