[KERNEL][ICS] Suave Kernel v6 ☰ Battery Friendly ☰ {OC,UV,2WCR,Gov,IO,FS,Net} 19-Jun

Guys, the latest kernel sources are out from SONY!! So, for all those who wanted kernel with OC and more features, here it is :)
With most of the useful features inbuilt! Link to old kernel -> here
Enjoy..

Q. Features?
  • init.d support
  • ro.secure=0 (that is now adb has native root access!)
  • Device is identified correctly (both Neo and Neo V) in recovery
  • ADB access in recovery
  • Clockworkmod 5.0.2.7 (credits DoomLord)
  • Overclock (OC): upto 1.6 GHz (use with discretion, i will not be responsible for ANY damage)
    new.gif
  • Governors: Smartassv2, Intellidemand, OndemandX, Smoothass, InteractiveX, SavagedZen, BrazilianWax
    new.gif
  • IO scheduler: sio added built in (default)
  • Filesystems: ext4 inbuilt, isofs, ntfs as modules added
  • Network: VPN support (tun/tap driver)
  • USB OTG: USB OTG support built in(mass storage, hid, mouse, keyboard)
  • Enable only features you want!! (See instructions below)
  • userinit support
  • Undervolting with vdd_levels sysfs
  • 2-way call recording patch (experimental)
  • swap:Enable with single line (How-to here)

Download
Please see new install instructions!!

suave-kernel-v6-neov.img <- NEO V
suave-kernel-v6-neo.img <- NEO
OC increased to 1.6 GHz, swap (can be enabled with a single line) How-to here.

Much better battery life!! + BrazilianWax & SavagedZen governors
CPU OC only till 1.4 GHz. Please see discussion here.

Previous:

suave-kernel-v3.1-exp-neov.img <- NEO V
Small bug-fix (no more kernel errors on logcat)!

suave-kernel-v3-exp-neov.img <- NEO V
suave-kernel-v3-exp-neo.img <- NEO
Added 2-way call recording + battery saver tweaks (full changelog post 2)

suave-kernel-v2-neov.img <- NEO V
suave-kernel-v2-neo.img <- NEO
Added UV (How-to below) + NTFS inbuilt (all changelog 2nd post)


suave-kernel-v1-neov.img <- NEO V
suave-kernel-v1-neo.img <- NEO


Stock WiFi modules
Required by only those coming from Night-elf kernel, CWM flashable.

Q. How to install?
Just as you install a custom kernel.

Steps:
1. Power down device and get into FASTBOOT MODE -> switch off device hold menu key & plugin usb. (LED notification turns BLUE)
2. check fastboot with "fastboot devices"
3. flash boot image
fastboot flash boot boot.img
4. Reboot with "fastboot reboot"
5. Enjoy!

new4.gif
How to enable/disable features?
This kernel sets properties to features so that they can be enabled or disabled easily
Code: 
shardul.module.tun=0
shardul.module.isofs=0
shardul.module.ntfs=0
shardul.module.hid_apple=0
shardul.module.hid_microsoft=0
Method 1: Edit /data/local.prop directly
Method 2: "writeprop shardul.module.isofs 1" on shell / terminal emulator for individual properties set/unset
Module will be loaded on next boot!
If you want to load module only for the current session, see this app!



Q. How to undervolt (UV)?
Easy methods -> andrev_oc, IncrediControl (Thanks to adridu for the tip)
OR
Query vdd levels (output: first column: frequency (kHz), second column: vdd* (mV))
Code: 
cat /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels

incrementing/decrementing all levels by a specified amount* (mV):
Code: 
echo '-25' > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
echo '+25' > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels

adjusting the supply voltage* (second value, mV) at a specific frequency (first value, kHz):
Code: 
echo '998400 1250' > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels

*: vdd values must be a multiple of 25 (enforced by the interface; the regulator doesn't accept other values)

@ALL:
1. I have noticed that v6 supercharger script adds "pm.sleep_mode=1" in build.prop

This causes high drain on some networks in sleep.. Just remove that line after install v6 supercharger script by zeppelinrox

2. If data is on overnight, it uses a lot of battery.. Use any script or app to turn off data when not required

Did you even read the OP?
There is a section on how to undervolt!!


@kibol44: Values are reset at boot.. So try low values (individually for all frequencies), if phone freezes or random reboots, then you are too low ;). After you have found the correct values for your phone, you would need an init.d script for setting values on every boot..


@ALL: 2-way call recording, some debugging features turned off (logcat is still enabled), VM readahead increased, NFS (which i dont think anybody uses, but available as module) turned off for better battery..

My phone running stable on it since the last 4 hours. Anyone else who is willing to test?

    Updated to v6!

    Changelog:
    = OC increased to 1.6 GHz (Popular request)
    + Swap on system (change amount by editing /data/local.prop)
    + VM readahead increased

    How to enable swap on /system?
    For first time users, it is enabled automatically (50 MB on system)

    For those using previous versions of my kernel..
    1. Make sure how much space you have on system
    2. Edit /data/local.prop and add the line
    Code: 
    shardul.swap.mb=[COLOR="Red"]64[/COLOR]
    Change 64 any value you want (in MB)
    3. Reboot
    4. After reboot, check amount of swap used by typing
    Code: 
    busybox free
    in terminal

    Updated v5

    Updated to v5 (v4 skipped ;))

    + MUCH better battery life
    + Governors: BrazilianWax and SavagedZen
    = Governors: Tweaked values
    - OC only till 1.4 GHz, removed some frequency steps (reverted to stock freq)

    OC code was causing battery drain (maybe vdd levels were not correct).. So I have reverted to stock frequency steps, with minimal changes required to unlock the 1.2 and 1.4 GHz OC.

    [Please reset values to min 245 and max 1024 MHz in No-frills CPU or SetCPU or any script that you are using before flashing this]

    Battery life is much better now (3% drain in 9 hours on idle) :D
