HELLO Everybody
This Guide Has 4 Parts :
1: Speed Patch : To Speed Up N900
2: Battery Patch : To Have A Long Battery Life
3: Battery Patch Non KP : For non kernel-power users
4: Tweaks : To Make You Enjoy N900
Part 1: Speed Patch
INFO
A lot of you must have heard about the 200 lines to speed up linux while blackhat announced 4 lines to do that and it is called miracle patch
anyway neither of the available tutorials on internel are working on N900
BUT For Fortunately i was able to apply it to Maemo 5 on N900!!!!!
You will notice a lot of improvements in hildon-desktop
and basically every thing will be improved
CURRENT VERSION : 2.0
What Does It Do
The CFS (completely fair scheduler) in our phone's kernel manages the allocation of resources (cpu/mem) between tasks.
It was designed to cope with server-class machines such as web servers and databases, giving all tasks equal access to resources.
This means if a server is really busy, then all tasks on the machine slow down equally.
Desktop/mobile class machines shouldn't work the same way as servers though.
They have a human user who expects the machine to respond and give feedback within a certain time.
If a machine is slow to respond, the user loses some sense of control over the machine.
This patch addresses the problem by taking note of what the user is doing right now, and using that information to accelerate the current task, and decelerate other tasks on the system.
The user won't notice the background stuff going slower, they will just see their app working fast. The patch does this by creating multiple classes of task
-------------------------------------------
/dev/cgroup/cpu/tasks
/dev/cgroup/cpu/desktop/tasks
/dev/cgroup/cpu/applications/tasks
/dev/cgroup/cpu/applications/standby/tasks
/dev/cgroup/cpu/applications/launcher/tasks
-------------------------------------------
If you look at the contents of these files, you'll see the process IDs of all the tasks in each class. CPU and memory are shared out to these classes using the files "cpu.shares", and "memory_limit_in_bytes".
When lots of tasks are demanding CPU/memory at once, the resources are handed out to tasks depending on their share.
This is why your phone feels nicer when you have this patch - the kernel automatically classifies tasks and devotes more of cpu/mem to the "application" and "desktop" class tasks, and much less to other classes like "standby".
Installing Speed Patch
Then Reboot twiceCode:sudo gainroot apt-get install speedpatch
------------------------------------------------------------
IMPORTANT
1-)If there was an error in xterm after speedpatch is installed and launched xterminal
that means speed patch was not applied
2-)Speed Patch may not be activated from the first 2 reboots
it may need up to 4 or 5 reboots
i still don't know why is this happening
but once it's activated it doesn't need any further reboots
to check if it was activated
read at the checking section below
3-)if you are having the xterminal problem and it disappear after xterminal is loaded then:
do this to fix it4-)And if your N900 improperly shut down because of an unexpected rebootCode:#(as user) rm .cache/launch/com.nokia.xterm.pvr
or because of a battery drain
then speedpatch will now be activated on the next reboot
to solve just reboot once
------------------------------------------------------------
Uninstalling Speed Patch
To remove the patch:
Then RebootCode:sudo gainroot apt-get purge speedpatch
------------------------------------------------------
BENCHMARK
The simplest way to see how the patch effect
is to open browser windows about 8 before applying the patch
and 8 after applying the patch
you will notice a huge improvement
---------------------------------------------------------------------------------
Part2 : BATTERY PATCH
INFO
This Tweak Improves The Battery Life of Our N900
For Standby And Continues Time Of Usage
CURRENT VERSION IS: 3.5
Compatible with all KP versions
When device is locked : or system is inactive or the brightness is off (except when having a call)
1-) vfs_cache_pressure goes to 10 : it's proven that doing this saves a lot of battery on standby
2-) change to underclock profile : vdd1 vdd2 enabled, (but with KPv48=> only vdd1 enabled) powersave_bias=20 and the stock voltages to avoid reboots
3-) renice 1 some processes
When the device is unlocked or the brightness is on
1-) vfs_cache_pressure goes back to 100
2-) overclock profile is loaded : vdd1 vdd2 enabled, conservative mode and powersave_bias=20
3-) renice 0 the previous processes
Extra Feature
Someone may say "i don't want my N900 to use underclock profile and pause some processes when i lock the screen because i'm downloading a large application to install it"
Solution is :
Open the keyboard, lock the screen and leave the keyboard opened
in that case batterypatch is temporary disabled
so locking the screen will activate it's features
Dependencies
dbus-scripts, kernel-power, kernel-power-flasher, kernelpower-settings
Installing Battery Patch
Code:sudo gainroot apt-get install batterypatch
Uninstalling Battery Patch
------------------------------------Code:sudo gainroot apt-get purge batterypatch
Part3 : BATTERY PATCH Non kernel-power users
INFO
This version is for people who doesn't use kernel-power
This Tweak Improves The Battery Life of Our N900
ONLY ON STANDBY
UNLIKE THE Battery Patch Full version
CURRENT VERSION IS: 3.0
When device is locked : or system is inactive
1-) vfs_cache_pressure goes to 10 : it's proven that doing this saves a lot of battery on standby
When the device is unlocked or the brightness is on
1-) vfs_cache_pressure goes back to 100
Dependencies
dbus-scripts
Installing Battery Patch Non kernel-power users
Code:sudo gainroot apt-get install batterypatch-non-kp
Uninstalling Battery Patch Non kernel-power users
----------------------------------------------------------------------Code:sudo gainroot apt-get purge batterypatch-non-kp
CHECKING
1. To check if Speedpatch was installed Correctly:
Open an xterm window
if no errors appeared that means speedpatch is applied
or
You Should see some filesCode:cd /dev/cgroup/cpu/user/ ls
-------------------
2.To check if Battery Patch was applied :
Then lock the phone and unlock itCode:sudo gainroot echo 1000 >> /proc/sys/vm/vfs_cache_pressure
Then
you should see 100Code:cat /proc/sys/vm/vfs_cache_pressure
If so then the patch is applied
FAQS
1-)
Q-) I cannot change max frequency with qcpu or any other gui cpu freq changer!!!!
A-) To change the max cpu frequency you need to edit the max freq at :
/usr/share/kernel-power-settings/overclock with any text editor ex:
and then change the maxfreq to anything you want down than save and quitCode:sudo gainroot apt-get install leafpad leafpad /usr/share/kernel-power-settings/overclock
IMPORTANT !!! IF YOU HAVE AN UNSTABLE N900
IT'S RECOMMENDED TO DISABLE VDD1 ... CHANGE IT TO 0
IF YOU WANT TO OVERCLOCK MORE THAN 805
2-)
Q-) My N900 shows low battery and when i lock the phone and leave it idle ..the battery bar will rise up again
A-)N900 will recalculate the remaining battery charge according to the way using it
.. if you are using N900 in a heavy way then battery bar will show less than leaving N900 on idle mode
----------------------------------------------------------------------
PART3 : TWEAKS
1-) You may try hardware accelerator wich will make hildon-desktop smoother
BUT it is known to be unstable so if it caused any hildon-dekstop crashs or reboots simply disable it
To enable it :
use any text editor to edit /etc/powervr.d/hildon-desktop.ini and change WSEGL_UseHWSync=0 to WSEGL_UseHWSync=1
so :
and changeCode:sudo gainroot leafpad /etc/powervr.d/hildon-desktop.ini
ToCode:WSEGL_UseHWSync=0
Believe me hildon will be much smoother but as i said before if any reboots occurred then disable it by changingCode:WSEGL_UseHWSync=1
ToCode:WSEGL_UseHWSync=1
Code:WSEGL_UseHWSync=0
IMPORTANT: if you was very unlucky with HWsync you may have to reflash Your N900
because it may cause a reboot loop
otherwise it is stable to use on 80% of N900s
------------------------------------------------------
2-) And you may also want swappolube and it's proposed values
to install it
once installed launch it then press on PROPOSED button then APPLY then STORECode:sudo gainroot apt-get install swappolube
------------------------------------------------------
3-) And you may also want tracker-cfg and lowmemory mode (will make tracker use less CPU and Memory wich will improve the speed a bit)
install it :
once installed launch it and choose lowmemorymodeCode:sudo gainroot apt-get install tracker-cfg
Then save and exit
------------------------------------------------------
4-) And ApMeFo app wich organizes folders your menu(try to reduce the shortcuts by putting them in folders) this will improve transitions
to install:
------------------------------------------------------Code:sudo gainroot apt-get install apmefo
5-) And installing CSSU with it's nice modified hildon-*
for installing it
http://wiki.maemo.org/Community_SSU
------------------------------------------------------
6-)Also kernel-power is recommended
to install it :
----------------------------------------------------------------------Code:sudo gainroot apt-get install kernel-power-flasher
------------------------------------------------------
IF YOU DID ALL THE INSTRUCTIONS CORRECTLY
You should have a really fast and smooth N900
BTW The Tweaks Are All optional But For the best result Apply Them All
Enjoy
Thanks for :
thingonaspring for helping me with speedpatch
vi_ for helping me with batterypatch
------------------------------------------
Full Removal script for speedpatch and batterypatch for people who messed up due the many updates
from attachments
Download and move to /home/user then execute
But remember to reboot after removing before reinstalling the patchesCode:sudo gainroot mv /home/user/MyDocs/speedpatch-batterypatch-remove.txt /home/user/sbr chmod +rwx /home/user/sbr /home/user/sbr

I have reflashed my phone,and i have just installed the lastest CSSU & battery patch & speed patch.
But when I played 2 sample videos with media player: the first time is ok, the second time it stop while playing, and the third times it said that "unable to play...Media...not support". So I uninstall the battery patch and reboot again, and my phone have reboot looped. I have to reflash once again.
The last time i use this version (in the attach), and I think it's the best choose for my phone.
