optimized kernel 2.6.32.9-perf

100 posts in this topic

Posted (edited) · Report post

hi all.i made some change in the kernel.

as i find it better i propose it to all...

i made some kernel and wifi optimizations.i also add a few more tweaks...

just flash the zip in recovery in case the zip is not working ,unzip it, then unzip your rom and replace boot.img, compress that at best in zip format then flash your rom . (i use winrar)

please give feed back about it: wifi(speed upload and dl etc...), and all the rest...

Enjoy it!!! i forget to say it is for styx(etc...) and onyx like(cm7.2)

boot for testing purpose---------------->

frandom.ko -----> http://www.mediafire...e610lh74v0hjqzy

push in system/lib/modules...and use it in conjonction with crossbreeder... http://forum.xda-dev...d.php?t=2113150 (if you have rngd and entro in system/xbin, delete them as they would conflict with haveged) you can type in terminal lsmod | grep frandom to check that frandom.ko is loaded... (once crossbreeder is installed /or if you using an init.d file to insmod the module.

Hi desalesouche,

I've tried to install your new kernel, but I couldn't.

Log from Clockworkmod Recovery v3.1.0. 1

Installing: /sdcard/optimized 2.6.32.9 kernel-u8220-8230.zip

Finding update package...

Opening update package...

Installing update...

Amend scripting (update-script) is no longer supported.

Amend scripting was deprecated by Google in Android 1.5.

It was necessary to remove it when upgrading to the ClockworkMod 3.0 Gingerbread based recovery.

Please switch to Edify scripting (updater-script and update-binary) to create working update zip packages.

Installation aborted.

Do you know how I can solve the problem without unzip the kernel?

I think, the problem is your update-script with my Clockworkmod version.

What version of Clockworkmod do you use?

Thanks!!

Solution:----> unzip the file...then copy boot.img on the root of your sd card With Terminal Emulator you must type this:

su

mount/sdcard

flash_image boot /sdcard/boot.img

reboot

tell me if it works for you...and it has been said a lot of time that Clockworkmod Recovery v3.1.0.1 is not working good with our pulse u8220/u8230.

after that you do what you want...if you use it just because of the feature who allow to partition sd card...you can partition sd card on pc.

Hi desalesouche,

My sensation with this kernel is that the power on/off is longer than usual.

What do you think?

hi all this is the link to my thread about compiling module for our 2.6.32.9 kernel....

as you can see, i am still a noob... ;)

but i am trying very hard day after day...to improve my knowledge and find solution....

googling is not all...those who have knowledge have to not forget those who are ignorant and provide them help and information...

often one who know how to read forget how difficult it was to learn...

voilà, c'est la vie!

any help apreciated...

my projects for the moment=compile frandom module..../enable ksm in kernel...

hi all.i managed to enable ksm in 2.6.32.9 kernel.

ksm should help a lot to improve memory and performance...> http://www.linux-kvm...age-merging-kvm

it would also help for cyanmobile 2.3.8 experience who ask for ksm enabled...will upload boot.img soon...

more information----> http://kernelnewbies.org/Linux_2_6_32#head-d3f32e41df508090810388a57efce73f52660ccb

yeah this actual boot.img is working with any rom.but wait a moment so i upload the new one which would be more compatible with cyanmobile 2.3.8 2013 who have the need of ksm anabled....you can set ksm in cyansettings...

i manage to compile frandom.ko. have to check if everything is working fine...

http://billauer.co.il/frandom.html

http://forum.xda-dev...d.php?t=2113150

This module is orders of magnitude (10-50 times) faster than the standard character devices ( Check this out - http://forum.xda-dev....&postcount=134 ). The erandom character device also installed by Frandom doesn't use up system entropy at all on top of being fast. You will need to ask your ROM developer to develop the kernel module for you and then place it in /system/lib/modules. CrossBreeder will then try and load it and if successful, make all the necessary adjustments so that both /dev/random and /dev/urandom are pointing to /dev/frandom and /dev/erandom respectively. The speed benefits are to be seen to be believed. But since each ROM requires a unique kernel module, this option is left optional ( but auto detect )

on cyanx2.3.8 2013 wifi is not working.i couldn't make it work..one can try to fix it. all wifi files are in system/wifi or if you check wifi from cm7 by cyanogenmod , in system/etc/firmware with one module in system/lib/module.

for the moment i am concentrating on ksm which give me reboot once running...and on frandom.

Hi Desalesouche,

I'm using the CM7 nightly versions from CM site, the last one dated is Feb 1st, 2013 but it is based on kernel 2.6.29. The question is, could I apply the new 2.6.32 optmized kernel over the previous one?

I will appreciate your suggestions

Thanks!

yes you can apply it but you will have to make some change...cos wifi wouldn't work .and you would have to check about libs/module

if you open zip from last cm7 update and you open zip from my last cm7 you can compare and make the necessary change...

try it!
