[KERNEL] i9000-B with BLN and more - GAKernel by LuisManson

This a custom kernel for the I9000-B there is no magic here so i wont add a lot of info
it has:
* TinyRCU
* BFQ scheduler
* ondemand governor
* BacklightNotification by Neldar
you will need the app to control/enable BLN: http://forum.xda-developers.com/showthread.php?p=8917392
included in this file:
zImage for heimdal
liblights backup (original in my rom)
liblight.so file inside correct path to replace inside phone (/system/lib/hw)
NOTE: this is for the Froyo rom of VIVO (brazil)
it also has adb as root even in recovery mode
i will try to keep xda updated but im sharing most of this on a spanish forum

man, that is awesome!
I'll try but now i'm using a new froyo rom for the I9000B: BVJJPD. Is that compatible with this kernel?
I did a post at PORTALANDROID forum using the same title as herer, talking about u work. I hope people join us testing, talking and donating, like me.
Just one more thing: thank u so much!!!

what about 2e recovery?

if we need CWM or Recovery mode to flash, i don't know what to do. we just don't have.

i had to remove BLN because it caused a probelm with bluetooth audio
carcassudo, thanks

I am gonna try soon as possible...
Thank you Luis for this.

this kernel is v4, it has a bug in bluetooth audio, and it does not have recovery e3, since the recovery kernel is bassed on the v3 kernel, with no CWM

using CWM gets stuck in INSTALLING UPDATE...

OPENING...
INSTALLING...STCUK!
did twice.

Good work you are doing here luis, HAPPY NEW YEAR.

thanks, you too!!!

[Q] adding governors

how do i add additional cpu governors on a custom boot.img?

I think u need an app like no frills CPU or set CPU to control your CPU and apply govners
just re read your post and I wouldn't no where to start by adding them to a boot.img. do u mean built into the rom ?

i mean adding more governors to the boot.img... i think it has something to do with the kernel??? cm7 only has 4 governors by default... not sure if its the rom that needs editing or the boot.img?

Yes - governors are hardcoded in the kernel as far as I know - so you have to recomile a kernel from source - including your changes - and then flash it. It's not just a simple editing of txt files...
More info about other governors you will find at cyanogen forum - as they developed them (e.g. smartass v1/2).

You are correct sir.

It shows all the files that need to be changed to add in a new governer ... if there's a + before a line, that means it was added, - means it was removed.

First step
1) Make sure you are running linux, or else it won't work
2) Download the source code from either opensource.sonymobile.com (for a stock kernel) or FXP github (https://github.com/freexperia/semc-kernel-msm7x30) for FXP Kernel.
3) unpack the source code
4) make changes to the source code you want to (i.e. adding in governors or io schedulers)
5) Follow this guide on how to build the source (note: the defconfig is probably different you'll have to check the /arch/arm/config folder to figure out which ones is the FXP one...)
6) Make it into a boot img following this tutorial
7) Try booting, if it works, check to make sure that the changes you made sticked. If it doesn't boot, well, you can ask questions in this thread and i'll help you
Any questions?
Pax

will try this.. tnx
EDIT:
-is it not possible to use with windows???
-so i have to build a kernel from scratch?? i can't simply add the new governors to an existing kernel?

A) Nope linux is the only way. I suggest ubuntu 10.04 LTE
B) unless you can create a way to decompile and recompile the zImage file (using linux) you're not going to get anywhere fast. (Governors are part of the built kernel, and can't be added into after the fact)

cant i simply copy the kernel from another boot.img file?? are there any other kernels that are compatible with cm7 fxp111 that has more governors??
is it possible to use kernels from other xperia phones using cm7??

1) technically yes, but kinda pointless because: 2) other than dooms (old) cm kernel (GSM) nope (I'm not sure if he had more governors or if it's compatible with with newer fxp)
3) nope, they use a different board.

tnx for the answers... i already asked about that old cm7 kernel... doomlord said that it was no longer compatible and needs to be updated to work with the newer cm7

[XS][Kernel][STOCK+] V5.4.1OC [14-03-13] Recovery Independent!!

For those who have an UNLOCKED boot loader.
Kernel Stock+ is
= Sony latest ICS .55 kernel base
+ Auto-root with SuperSU
+ Init.d
+ Governor : Badass, Intellidemand, Interactive, Lagfree, Hotplug, Wheatley
+ I/O schedule : SIO, ROW, ZEN
+ elf extract (support recovery in FOTA partiton)
+ few tweak
+ OC to 1674Mhz(some version)
Stock+ V5.4.1 (OC)
- Over clock again to 1674MHz
- Port few lib, optimize from Open SEMC kernel
- Omit smartassv2 it cause my phone stuck at max frequently.
http://www.mediafire.com/download.php?hsma936uzlasgao
Stock+ V5.3 (Not OC)
http://www.mediafire.com/download.php?ohybzjcfu1ad6hc
- Update recovery TWRP 2.4.1
- Support elf extract so you are no longer tie to TWRP 2.4.1. Now you can update TWRP to the latest version or even install CWM. Check http://forum.xda-developers.com/showthread.php?t=2173202
- Fix Auto Root
- Remove PeqasusQ
- Add Lagfree, Hotplug, Wheatley
Stock+ V5.2 (Enable to Over Clock to match XSL speed)
http://www.mediafire.com/?4n0n5b04g76h8ew
- Change max frequency to 1674MHz
- Change RAM Disk to limit max frequency at 1512MHz
Stock+ V5.1 (update TWRP to V2.3.3.0)
http://www.mediafire.com/?ehkzz5lb59zgbxd
- New ramdisk structure. Now ramdisk split into two 1st for recovery and 2nd for Stock ICS boot.
- 1st ramdisk is ported from http://forum.xda-developers.com/showthread.php?t=2075562.
- 2nd ramdisk is exacted from sony stock kernel.sin merge with ramdisk from Advance Stock Kernel this should retain "autoroot" function and "init.d" support
Stock+ V2
link : http://www.mediafire.com/?vzpj4b6kpoa5zsl
This kernel feature
- build from .55 source + fix cache formatting issue
- little mod ram disk to set minimum frequency at 192000
- on demand tweak for better battery life.
- autoroot with superSU
- Xperia boot screen
Stock+ V1
Link : http://www.mediafire.com/?5sb5352k7pz5lc5
It is unmodified STOCK kernel extract from .55 kernel.sin plus CWM with auto root functionality.
I made a little mod to ramdisk to make it auto root with SuperSU instead of Superuser. The wifi module also replace with the one from stock firmware as well. The wifi module in Advance stock Kernel is not compatible with this kernel.
The kernel work just fine but I notice some bug when I try to format cache or wipe cache it will cause your cache partition corrupt. So if you like to use unmodified stock kernel please remember NOT wipe or format cache.
Well if you already wipe/format and want to get around the problem just simply install other kernel e.g. advance stock ICS17 or my stock mod kernel list above then format cache after that reinstall unmodified stock or you can leave it as it is.
Note.
- 28/01/13 : just found a bug regarding to setcpu and antutu set at boot not appear to set both core correctly. Please give No-frills CPU control or Kernel tuner a try but remember not to use with pagasusq.
- To install by fastboot just extract kernel.elf from the zip.
- Source is outdate because I can not upload a big file. I will update source as soon as I get proper internet connection.
- Now you can update TWRP to the latest version using goo.manager or even install CWM. Check http://forum.xda-developers.com/showthread.php?t=2173202
Feedback is appreciate.

Can you make one with SuperUser please?
SuperSU is not much user friendly as Superuser :'(

please verify and confirm..this flashable zip i made is composed of .55 firmware stock kernel, cwm and supersu v.97

I would used it if you used Superuser but you used SuperSU which is not so used friendly as Superuser.

I think this is different mate. The one you provide is not the real recovery. This is the same way people use for Locked boot loader. The recovery is locate in "system". If you format system you will loose it or if you install new ROM which has script to format system you probably loose recovery!!
Mine the recovery is not in system partition. It is loaded in ramdisk. You won't loose it even you format system.
Cheers.

I did it but for now it is in elf format. Please check first post.
You probably not need it because if you already rooted with ICS16 which come with superuser then the kernel will not reroot your system.
I'm still learning, could you please explain or give me some info about how you find user friendly of superuser? I read around here and lot of people said supeSU is quicker.
Cheers,
tosa.th

I am not a Dev but since my 1st Xperia NEO I have always used Superuser. I only once used SuperSu and its was last night When I was looking for a way to Root .55 of my Xperia S.
The used Interface it kinda messy and had a lot of option but in Superuser it just a few thing and easy to understand.
I don't know about others but As far as I know and Experienced most of the xperia user and even my friend use Superuser instead of supersu.

It suppose to work on windows but you will need cgywin. You also need some other software like phyton 7zip java etc. If you have Linux then it will be easy to install all those software.

Great work.
I have a unlock bootloader and Whit this kernel there is an increase of performance.
Now i have the stock. 55 and Whit the antutu and i have 8390
Whit cm10 i have 8900. I think this is a Great kernel.

Hi, I've just added this kernel to the Xperia S Development Index

Init.D Not Working

Hi there guys! I'm currently using CM9 with the following tweaks/mods/kernel that you can see on my signature right now and I'm having problems with init.d not working. I hope you can help me guys! Thanks!

1. Which init.d script is not working, exactly? Only one or several? Or all of them?
2. Post here the result of:
Code:
ls -la /system/etc/init.d

The init.d should be, the ROM itself is supporting init.d ... Any more details?

I upgraded to CM9 RC3 and init.d's working fine right now. I saw on the changelog that it includes init.d scripting fixes so I guess RC2 has a faulty one.

Hi there guys! I'm having some problems again with init.d not working. It only seems to be triggered whenever I install a new custom kernel by flashing it, wiping the dalvik cache and cache then fixing the permissions. The problems is, whenever I check Seeder to see if it's working or not via Terminal Emulator. Seeder says it's off although it's set to run at every boot. The things that I've tried to fix it is by restoring the /system partition of my RC6 backup with no mods/scripts or custom kernels installed. How do I prevent it from happening again as doing all those things are time consuming.

Can anyone help me?
