echo 75 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold
echo 150000 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
end script


I have don this, but how do i start the script, or make it start automatic when i start the phone? i have googled but no luck..

Please need help!

(i am a BIG noob, sorry!)
The script run by itself when the phone is loading, so if you just added the script, simple reboot the phone and it will be loaded.

i copy a file from /etc/event.d to /home/user and rename it to overclock and then edit the file and pot the text i whanted.

maybe that whay it donīt work...

what type of file ending(name) do a script have, .txt .ini m.m? (i do not no how to make a script file i x terminal...sorry)

Ah, and for safety, I have extracted the /etc/event.d/kernel-maemo tweaks in a script which I can manually launch after booting
Hi,
Did you try to go to the picture gallery, open a photo, and test the autorotation?
With 125 Mhz it should slows\breack for miliseconds..not smooth.
Have you tried?

Damn!
Some week ago i owerclocked my n900 to 800MHz fiasco kernel , Everything was fine.
Until now.

I just update sygic maps ,and wandering to try it , after application start ,can't lock ,then reboot occured, after boot no more gps lock ...at any gps software - nor a-gps lock (stuck in some place where i never was)
flashed back to stock kernel - no change
Sorry about my englis
Any sugestions ?
....please ...

3. make a file in "/etc/default/" and name it "kernel"
4. edit the "/etc/default/kernel" file to your likening
5. write "start kernel-maemo" in the terminal to get OCd

The two files can be copied from here
Woo that was useful... thanks,,

for step 2: Is that a Notepad file??

,,, btw, what would the following set the dsp to?? and what code needs to be changed to set it to 500?? thnks

UP_THRESHOLD=75
SAMPLING_RATE=150000
VDD1_OPPS_VSEL="30 30 30 30 33 38 45 45 48 48 54 54 60 72 72"
DSP_OPPS_RATE="90000000 90000000 180000000 360000000 400000000 430000000 430000000 430000000 430000000 500000000 500000000 500000000 500000000 520000000 520000000"
MIN_FREQ=500000
MAX_FREQ=850000
SMARTREFLEX_VDD1=0
SMARTREFLEX_VDD2=0

my current plan is to rename kernel-maemo to kernel-power (for power users)
as there are some trademark issues http://maemo.org/legal/terms_of_use/trademarks/.
I would upload the new kernel-*power packages and a tiny transition package "kernel-maemo-flasher maemo23" that would require kernel-flasher-power and could be removed after installation.
I also plan to change the DSP frequencies from Hz to MHz so that we don't need such long numbers.

For the upstart scripts I would create a new package "kernel-power-settings"
that we could develop independently.
In the future it could also contain a daemon that make sure that the min. frequency is preserved over phone calls.

If have suggestions for a better name, please let me know.
I like the name kernel-power and I also think its a good idea to have kernel and upstart scripts/config in separate packages.

EDIT: http://wiki.maemo.org/Overclocking is the most uptodate source of information

the new kernel kernel-power-flasher has been uploaded to extras-devel and is ready to brick your devices
DSP frequencies are now specified as MHz, it includes squashfs, Matan's LED fixes,
and two more crypto modules.

Please vote for it if it works for you here

I've renamed all packages to kernel-power* and made kernel-maemo-flasher
a transition package. I've never done this before in Maemo so I don't know whether
it will work in HAM. It worked for me with
Code:
apt-get install kernel-flasher-maemo
apt-get remove kernel-flasher-maemo
alternatively,
Code:
apt-get install kernel-power-flasher
apt-get remove kernel-flasher-maemo
Don't forget to reboot after the installation!

the new package kernel-power-settings contains the upstart script and
kernel configurations. it is experimental and may totally brick your device!
it will automatically move your old kernel or kernel-maemo upstart scripts to /root

Ideally, you would install it and then as run the following commands as root (install rootsh and enter "sudo gainroot" as user to become root)

1) to try a configuration (you can replace "ideal" with default, lv, ulv, xlv
or specify a file you created based on the template /usr/share/kernel-power-settings/default )
Code:
/usr/sbin/kernel-load /usr/share/kernel-power-settings/ideal
Note: do NOT modify the files in /usr/share/kernel-power-settings/
instead copy them them as in 3) and then modify the file /etc/default/kernel-power

2) to permanently install a default configuration
Code:
rm -f /etc/default/kernel-power
ln -s /usr/share/kernel-power-settings/ideal /etc/default/kernel-power
3) or your own config
Code:
rm -f /etc/default/kernel-power
cp <filename> /etc/default/kernel-power
4) and to immediately apply it
Code:
/usr/sbin/kernel-load
For beginners and "noobs" (beginners that can't spell correctly...):
first reboot. then try 1) and check whether the device is stable.
then do 2).
If want to create your own configuration I recommend the procedure in
http://talk.maemo.org/showpost.php?p...postcount=2891

to reset it to the defaults use
Code:
rm -f /etc/default/kernel-power
and reboot.

Have fun! (and remember not to try >600MHz unless you want to fry your device)

Doesn't seem to.

When I go to update the old one:
Code:
Unable to install 'kernel-flasher-maemo'
Conflict with application packages:  kernel-modules-maemo
                                     kernel-maemo

                                     kernel-maemo
or install the new one:
Code:
Unable to update 'kernel-power-flasher'
Conflict with application packages:  kernel-modules-maemo
                                     kernel-flasher-maemo (<= 2.6.28-maemo22)
                                     kernel-maemo
                                     kernel-modules-maemo
                                     kernel-maemo

apparently HAM doesn't support transitions.
please use apt-get instead.
does anybody know how to convince HAM to upgrade?
