First off, I am NOT the maker of this sexy ass Kernel! This was compiled by Imoseyon & i had nothing to do with making it, so please give thanks to him for this. I'm just posting our builds here so he don't have to maintain multiple threads!This is an AOSP kernel (Jellybean only). Use this thread to report bugs, etc.

DOWNLOADFEATURES
  • Unnecessary components removed for lean and fast kernel.
  • Compiled using latest Linaro compiler with additional optimizations.
  • Latest Linux updates applied.
  • Some commits from latest CM10 kernel cherry-picked and merged. Starting v2.0, cm-10.1 source is used as base.
  • Ramdisk optimizations.
  • OC'ed to 1.9Ghz (limited to 1.51Ghz at boot, use an app to change max freq), and all frequencies undervolted
  • Tuned Deadline I/O scheduler. ROW Scheduler default.
  • Fast Charge (toggle via the "ffc" script - open terminal, type ffc then enter, plug in phone via USB)
  • On-demand governor backported from Linux 3.5
  • InteractiveX V3 - optimized for S3, screen_off_maxfreq sysfs interface (default set to 810Mhz). (Note: I didn't change the name to interactivex in the kernel this time)
  • Auto-brightness tweak - slightly brighter than stock kernel in some instances where it gets too dark.
  • Fixed governor switching bug where switching from ondemand to another governor could keep cpu1 offline until you switch back.
  • wakelock tweaks for better power efficiency.
  • Modified thermal control - flashing zip will replace thermald with my version that will prevent ROM from setting max freq beyond what you initially set it to.
  • Fixed governor transition latency.
  • Custom voltage control via sysfs (recommend using setcpu, voltage control, or system tuner)
  • lkflash script to flash latest kernel versions
  • lkconfig script to configure leanKernel specific features
  • Two more sleep states: Retention and Standalone Power Collapse
leanKernel scripts
lkflash (flash latest leanKernel versions from your phone)

root@android:/ # lkflash

leanKernel flasher
------------------
1) latest stable (recommended)
2) latest experimental
3) check/display versions

FLASH AT YOUR OWN RISK. I'm not responsible for my mistakes or yours. ;)

---
1) Restore stock behavior of keeping voltage minimum at 1150mV if CPU needs it.
2) Remove the above vmin override (leanKernel default).
3) Overclock 3D GPU to 480Mhz (exp build only, for now).
4) Return to stock GPU max at 400Mhz (exp build only, for now).
5) Revert /system/bin/thermald to stock.

Please enter a number between 1 and 5 (or press enter to exit): 1
vmin override re-enabled.
ffc (force fast charge toggler)

FAQ

Having trouble from the media process?
Try this command in terminal : pkill -f media (after "su" of course!)
SIO vs Deadline?
OnDemand vs Interactive(X)?
Read this post: http://rootzwiki.com...280#entry938766

Are you having intermittent weirdness and suspect issues with cpu voltage? If so read this post:
http://rootzwiki.com...010#entry953903
TLDR; In order to allow custom user undervolting, my kernels bypass stock samsung kernel's code subroutine that overrides your minimum voltage to 1150mV. Your phone's CPU may be one of the few that needs the extra juice for stability; if so, increase minimum voltage up to 1150mV.

How do I OC GPU?
First download the latest experimental version. Then use the "lkconfig: command!

on bluetooth motorola headphones i get static, even with the volume all the way down...on phone

at first i thought i had a defective pr. of headies, but i tried them out on the mez with devil kernel and it was clear as bell.

just seems CM10 stock without any flashed kernel doesnt affect the bluetooth areas for me. both kernels this one and the the other gimmie static
