I'm not a developer, I made this kernel "for fun" and for personal use, but I accept (and I need ) help and suggestions from everyone.

What is needed:
  1. LG Optimus L9 P760
  2. busybox in /system/xbin/
  3. Unlocked Bootloader
  4. JB Stock ROM (V20B/V20C/V20D)

Installation:
  1. Make a backup of your current ROM (or just the boot.img)
  2. Install the .zip file from recovery
  3. Recovery -> Wipe cache
  4. Recovery -> Advanced -> Wipe dalvik-cache

Downloads:
  1. http://q.gs/4JJwr 27-05-2013 (latest) (kernel panic?)
  2. http://q.gs/493ni 26-04-2013
  3. http://q.gs/491lz 18-04-2013

Uninstall:
Features:
  • Default governor: interactive
  • Default I/O scheduler: deadline
  • init.d support
  • Added support for some file systems: NTFS (r/w), UFS (r/w), HFS+ (r/w), CIFS
  • ZRAM (60) enabled and activated at boot (thanks to denzel09 for the commands) (delete /system/etc/init.d/11zram to disable)
  • CLEANCACHE and ZCACHE
  • CPU and GPU undervolted
  • CPU frequencies (MHz): 200 MHz -> 600 MHz -> 999 MHz -> 1100 MHz -> 1220 MHz
  • GPU frequencies (MHz): 227 MHz -> 456 MHz
  • Enabled "sanjose" governor
  • Added "smartassv2" governor
  • Added "pegasusq" governor
  • Added "sio" I/O scheduler
  • Added "row" I/O scheduler
  • KSM availabile
  • NOT TESTED: USB OTG support, I can't try this, if you can please leave a feedback. Maybe a powered USB HUB is needed.
  • "/storage/external_SD/Android/data" will be mounted in "/storage/sdcard0/Android/data" at boot time (delete /system/etc/init.d/12extdataobb to disable).
  • "/storage/external_SD/Android/obb" will be mounted in "/storage/sdcard0/Android/obb" at boot time (delete /system/etc/init.d/12extdataobb to disable).
  • Patches for DriveDroid (from this thread)

Known problems:
  1. Some users get a "kernel panic" at boot time, I don't know why this happen and I don't know how to solve it ..
  2. Offline charging isn't working

Source code: http://q.gs/491lV
I've got problem with github, source code is on gitorious.

Thanks for the feedback
The pegasusq governor will drain more battery then the stock kernel now.. I have to optimize it.
You can set smartassv2 with setcpu/antutu cpu master, it will save battery.

You're right... I'm fixing it in the next version. You can mount that directories with this command (terminal emulator):
"sh /init.post_boot.sh"

Yeah, 51.1 fps in Epic Citadel benchmark. On stock gpu there was 44 fps, so the oc works.
Thank you for fast reply, great work and keep doing.
