    [kernel][TW][MB1 v2.2, 4/7/13] Leankernel: Minimalistic Kernel

    Unofficial build of the minimalistic kernel, Lean Kernel! This is another unofficial release by myself and this was posted with permission as always!

    This is for TouchWiz roms ONLY. This will not work with AOSP and as of right now, I do not plan on building the AOSP version of this. Bugs should be reported here. Always fix permissions as with any kernel.

    Mod Type:: Kernel

    Difficulty:: Very Easy

    Mod Status:: Stable

    Apply In:: CWM Recovery

    Requires Root:: Yes

    Source::
    This is a Touchwiz kernel. Use this thread to report bugs, etc.

    DOWNLOAD


    FEATURES
    • Unnecessary components removed for lean and fast kernel.
    • Two new sleep states: Retention and Standalone Power Collapse
    • Compiled using latest Linaro compiler with additional optimizations.
    • Latest Linux updates applied.
    • Ramdisk optimizations.
    • OC'ed to 1.9Ghz (limited to 1.51Ghz at boot, use an app to change max freq), and all frequencies undervolted
    • ROW v4 I/O 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)
    • Fixed governor switching bug where switching from ondemand to another governor could keep cpu1 offline until you switch back.
    • Power efficiency fixes - wakelock tweaks, gsiff_daemon workaround, etc.
    • Modified thermal control to play nicely with OC.
    • 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

    leanKernel scripts
    lkflash (flash latest leanKernel versions from your phone - must su first)
    Code:
    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. ;)
    
    Please enter a number between 1 and 3 (or press enter to exit): 3
    Please wait...
    
    >>> Current version: 1.0, Latest stable: 1.0, Exp: 1.0exp1
    lkconfig (configure leankernel specific settings which will persist between reboots - must su first)
    Code:
    root@android:/ # lkconfig
    
    leanKernel configurator
    
    ---
    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)
    Code:
    root@android:/ # ffc
    Fast USB Charge: ON
    root@android:/ # ffc
    Fast USB Charge: OFF

    How do I use USB Fast Charge?


    • 1) Unplug from USB cable.
    • 2) Open Terminal Emulator, type "ffc" (without quotes) and enter. This command will toggle your fast charge state.
    • 3) Plug it back in.
    • Note: running the same command again will disable fast charge.
    • Also, when fast charge is enabled USB communication will be disabled.

    Why does my top speed become 1.9Ghz even though I never set it higher than 1.5Ghz?
    Your ROM's thermal control will automatically set your max speed to top kernel speed, *after* it's been tripped once due to high cpu temperature. Unfortunately there's not a whole lot I can do to fix that in the kernel. Ask your ROM dev to see if they can fix /system/bin/thermald. Read
    this post


    . UPDATE: v0.5 (and higher) kernel has a workaround to fix this issue.

    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.

    What is the kernel default voltages?

    lol I'm actually considering tackling that anyways to be honest...

    I got lean kernel built for d2cri but v2.1 isn't holding the clock settings and keeps reverting to stock speeds when I close out my OC apps (I tested with SetCPU and Rom Toolbox Pro to verify it wasn't a bug with one or the other. I'm thinking it could be a problem with not having Busybox installed or even needing 2nd init support built in). I'm about to build imoseyon's v2.2 and use droidroidz's ramdisk. So far however since I rebuilt the 2.1 however it's sticking through the app closes(only have 1 installed at a time)

    ikr... well 2.2 seems more stable and solid. It's based on MB1 so i don't have to sweat non working hardware like the modem. Camera works perfectly so i think I'm going to release it

    I've never changed the kernal on a phone before. I assume you flash it as a normal zip through CWM, or whichever recovery you prefer?

    I love the new boot logo. Never seen that done in a kernel surprisingly.

    That's actually the stock Android animation when there is no other animation. It doesn't look like it has support for it but this is a minimalistic kernel

    Edit after the fact:
    If there's no bootanimation.zip it shows the Android logo. I need to look into getting the Samsung qmg support for this kernel and fall back to the .zip
