sI don't want to write a big OP.

This is a kernel and liblights modules I compiled to use with the Galaxy s II Plus.

Features

- BLN(Backlight-button-notification)

- compiled with linaro-gcc 4.9.1

- additional cpufreq governors: smartassv2 and scary

- additional I/O scheduler: fiops

- optional overclocking

- performance/battery tweaks(not many yet, more to come)

- linaro arm topology

- frandom

- dynamic fsync control

- init.d support for stock rom

- f2fs support

- linux kernel 3.0.101

Installation

- be sure, that you have a GT-I9105(P) and are on a compatible rom

- flash the .zip file with a custom recovery

- wipe cache

- To change your kernel settings I recommend you Performance Control

- BLN could eat some more battery

- the initial name of this project was custom_kernel

Configure BLN notifications

You can execute these lines in any terminal as root. If you want the settings to persst after reboot, create an init.d script with your settinǵs.

enable:

Code:

echo 1 > /sys/class/misc/backlightnotification/enabled

disable:

Code:

echo 0 > /sys/class/misc/backlightnotification/enabled

disable blinking:

Code:

echo 0 > /sys/class/misc/backlightnotification/led_blink_duration

change blinking duration (in milliseconds):

Code:

echo <time> /sys/class/misc/backlightnotification/led_blink_duration

Please attach a kmsg and a logcat, too. You can get a kmsg like that with adb:

First. Downloading...
I have a question... You can set overclock to 1.3-1.4ghz? Because on actually 4.4.2 we can't overclock... Thanks

hasdroid · Jan 18, 2014

Thanks but see this...
Why???

Will this kernel work with the vibration fix for your cm11?
Thanks for doing this, by the way

Yes.Install this after installed vibration fix and you will have no problem.

BLN control from market worked for me. Did you try "Led notification", and turning your screen off?

I tested free version and it's worked perfectly but pro version didn't work ?

Thanks. Should I wipe cache and dalvik after I have installed this kernel?

Well, it works fine, but I can't see smartassv2 governor, should it be there (Scary is present)? And I can still oc to 1300Mhz (I could do this after vibration fix).

EDIT: Oh and @CoolDevelopment have you already included this sdcards swapping via build.prop here? Because I see I can mount pendrive via OTG (well, it does not work, but shows as it was mounted - I used app called stickMount).

CoolDevelopment · Jan 18, 2014

I think I forgot to enable Smartassv2 in defconfig. And pro version of bln control works for me, try to clear it's data. Usb otg fix isn't inclueded and swap sdcard needs some more testing

I works on pro too...
Test works fine. But
Make sure that you have switched off scedule BLN which is on by default. and you have enabled BLN for Android-OS apps.

nice work devs .. i'm loving this phone because of u guys .. and i think in the future don't make oc kernel it has problem without perf .. i think we are doing it with wrong way ..it needs some moding to feel perf in 1300 or above ... can anyone post antutu score ......good luck

hi devs use this .. just flash Zimage with this you can make flashable zip .. for all rom's without ramdisk .. it will extract ramdisk and build boot.img itself .. one zip for all rom's .. replace zimage and modules no need to ramdisk any more ... good luck
