ok, let me give you a mini-tutorial (the scripts are so powerful that a full description woiuld take a lot of time to write):
Note: this refers to kernel-power-flasher >= v27 and kernel-power-settings >= 0.8 from
extras-testing.
in theory, if you install the new version the old settings should still work and be loaded during boot.
(kernel-config = sudo /usr/sbin/kernel-config, here abbreviated)
shows you the current configuration of the kernel.
If you have loaded an old config, or changed the current settings manually or using ClockfreqUI you can save the current settings with
this will automatically save it in /home/user/.kernel/myconfig
and create the directory if necessary (replace myconfig with any name you like).
To save it somewhere else (why would you?) use the absolute path.
loads the configuration. if the filename is not absolute (e.g. "./myconfig") it searches
for the file in the current dir, /home/user/.kernel and /usr/share/kernel-power-settings/
Without a file name it loads /etc/default/kernel-power, or /usr/share/kernel-power-settings/default
Do NOT modify the files in /usr/share/kernel-power-settings. They are templates.
The template names are: default, lv, ulv, xlv, ideal.
copies the configuration file to /etc/default/kernel-power (or symlinks if it is a template file from /usr/share/kernel-power-settings). If you do not specify a filename, the current settings are saved in /etc/default/kernel-power.
These settings are then loaded during boot.
sets the limits to [min,max].
If you use "-" for a frequency, the current value is used. For example, "kernel-config limits - 850" only changes the upper limit to 850Mhz.
(e.g. 500 48 400)
can be used to test voltage and dsp settings with a certain frequency.
it overwrites the current settings for that frequency and locks the CPU
to only that frequency until you run "kernel-config unlock" to unlock it.
The boot sequence:
the kernel settings are only loaded if you had a normal reboot or shutdown
but not after a crash. In that case the file /etc/kernel-power/.notloaded is created
and a GUI app could notify you and ask whether to load the settings again.
The settings will be loaded at the next boot again unless it crashes again.
you can edit the files in /home/user/.kernel/.
here is the content of the default template:
there is a separate file /etc/defaul/kernel-boot for boot options.
these two options are highly experimental and may brick your device!
operations before mounting /home:
if you have a script (e.g. for repartitiong) called /etc/kernel-power/pre-mount.once
it will be executed once and then moved away.
with FSCK_HOME enabled the /home partition (first ext3 on eMMC) will be fsck on boot.
alternatively
should check it only during next boot.
disables it only for the next boot.
if you reset or reboot the device during fsck, it will not fsck (only) during the next boot.
all messages are logged to /etc/kernel-power/pre-mount.log
If you know how one could show a fancy LED animation from the shell during fsck contact me.

This 500 Mhz kernel, is saving the same or less battery then yours 125 Mhz. It uses same or less voltage (check the wiki to know the correct values) (3 reasons)

@titan, that's some serious amount of work.
Now we just need a really nice GUI front-end app to make it easy to take advantage of all the special things we can do with these scripts. I wish I was a good coder but I'm not. =(

My doubt is the Next ...
I use the clock at 850MHz - 1GHz
minimum is 850MHz.
When I receive a phone call to the Clock falls 500mhz
How do I maintain it to 850MHz, even after receiving a phone call?
Can Make a shortcut to leave the desktop, selecting him for Ira 850MHz.
Thanks

please help with this? thanks.
you can reinstall it after the upgrade in PR1.2 (works fine with PR1.2alpha)
for the version info

Great work titan!
Does the new kernel-power-settings support the 'avoid_frequencies' feature?
(So I can get rid of my 'kernel-power-step2' script
)
