• I/O Schedulers included: BFQ, CFQ, NOOP, DeadLine, ROW(default), SIO, ZEN
• Overclocked to 1.6GHz (1.4 GHz default, overclocking is optional).
• Optional overclocking for GPU upto 520 MHz
• Lot of Configurable Tweaks via STweaks
• CPU Frequency stepping in 16 steps when full range is used.
• GPU Frequency stepping in 5 steps. (Samsung uses 2. Cyanogenmod uses 3)
• View live GPU stats
• Profile management via STweaks for performance and battery
• Dynamic Hotplug Mode (Less CPU1 usage)
• Swappiness is set to 0 in zram-swap script. With ZRam is in action while you run out of memory.
• Fully customized RAM-DISK to inherit more optimization
• Fuel-Gauge Auto-Reset on first boot for proper battery calibration when user deletes respective script from init.d.

******* THIS KERNEL IS NOT RESPONSIBLE FOR ANY OF YOUR CRY
******* BE POLITE OR ELSE YOU WILL BE REPORTED FOR INFRACTION
******* SELECT PROPER-CLEAN TOUCHWIZ ROM. I RECOMMENDED MINIMAL TOUCHWIZ ROM.

******* MOST IMPORTANT => IF YOU ARE UNHAPPY WITH THIS KERNEL "MOVE ON"
******* THIS KERNEL IS ON PUBLIC DEMAND. JUST FOR YOU.

​

Warning:

• It's your device. It's your responsibility for what you flash. Do not blame us.
• DO NOT flash over other custom kernel as that kernel that has incompatible/unstable/non-tested init.d scripts.

You may post anything related kernel. Make sure to mention ROM name, Governor name, IO Scheduler name.
Feature request is served if feasible.

Happy user? How about small cup of coffee for me? Click Here.
​

Flash Superuser_CWM only if root is lost. I will be implementing sure-root method in kernel soon.
Install Performance Control to set CPU OC/UV, schedulers, governors.
Install STweaks only if it is not auto-installed on flashing kernel. It gives control over GPU and many other tweaks.

Topic explaining all basic Governors & I/O Schedulers: Click Here

Governor we HIGHLY RECOMMEND to use as default:

Hyper -

The Hyper (formerly known as kenobi) is an aggressive smart and smooth, optimized for SMDK4210 board getweakt and, based on the Ondemand, which was getweakt of Arighi and was equipped with several features of Ondemandx suspend imoseyon. (Added by sysfs, the settings suspend_freq and suspend Imoseyon's code) is the behavior of the hyper Ondemand if he is in action, very similar. He also has the Arighi's fast_start deep_sleep and detection features. In addition, the maximum frequency is in suspend mode 500Mhz​

IO Scheduler we HIGHLY RECOMMEND to use as default:

ROW -

ROW is Read Over Right. As name suggests it services more READ requests than WRITE taking care that WRITE requests don't starve.
It is most suitable because Android handhelds unlike desktop hardly uses multi-threading and a user seeks more of responsiveness than giving more input.
​

zzmoove is ported governor (by me) from SGS3. Read about it HERE.​

My Recommendations:
Recommended Governors: HYPER > SmartAssv2 > LulzActiveq > Abyssplug > Zzmoove > Pegausq > Others
Recommended Schedulers: ROW > ZEN > CFQ > SIO > NOOP > Others​

In case you have SOD (Sleep of death), please check minimum frequency. It should be greater than 100 MHz.
Recommended 200 MHz.​

F.A.Q.:

Q. I am getting FC / Performance control not working. What is the solution ?
A. Reboot in recovery. Wipe cache and dalvik cache.

Q. I am getting sleep of death. What do I check ?
A. Adjust minimum frequency to 200 MHz and not lower.

Q. Which is best governor and IO Scheduler?
A. All of us have different choices. There is no thing like best governor or IO Scheduler.
You need to set your personal favorite. I have posted my recommendation in above post.

Q. It takes long time to boot. What is wrong ?
A. Nothing is wrong. Let NXTW optimize your apps and database.

Q. How to insert a module that's available in /system/lib/modules?
A. Safe to be root. In terminal or adb
su
insmod /lib/modules/<module_name.ko>
You can request your required module, if you want.

Q. How to know which modules are pre-loaded by kernel?
A. Terminal or adb:
lsmod

Q. I want to help dev debug an issue providing a kmsg. How to?
A. After the problem (random reboot/freeze/lockup), do not pull out battery to recover. Just long press power button so that device can reboot. Then connect device to PC, (provided you have setup adb), type
adb pull /proc/last_kmsg
Save the file as .txt and post in the thread along with description of the problem and possible way to reproduce it.
If you can't use adb from pc, just copy last_kmsg file from /proc directory to internal sd, copy it to your PC and post in the thread.

Go for zai89's suberbean lt4, for me it is currently the best one. Stable, great battery life, fast and clean. I had to install xposed separately but it was a breeze. Highly recommended !

Finally.....
Will flash it later, thank you.

I don't believe I made a TW Kernel.

My device with your work = PERFECTION ACHIEVED!

lol... which ROM? And do you even read before downloading?

I'm on sweet rom v7 lt4 and come from coh kernel. I 've done a wipe cache and dalvik. First boot ok and about 2 mins my phone freeze. Trying to reboot in recovery mod = blackscreen
I fix it with philz kernel lt4 and odin, my download mode wotking fine ; )

Recovery is same as COH Kernel. I actually got from him on PM.
I am JonROM, after 1-2 min it got stable.

This (Initial jitter) is expected behavior since merges are not complete.

 

[pikaone]

I know your good kernel neobuddy, i will wait for another testers, sometimes freezes can arrived, but unable to boot in recovery mode. Maybe a bad flash ....

Agreed. Sweet Rom V7 slows down to almost freeze.
Tried to reboot recovery but black screen after N7000 Logo.
No normal reboot, no recovery.

Odin-> Philz-Kernel. Reboot ok.
Back to c.o.h.-Kernel.

Neobuddy, remove your download link before noobs flash this and crying after you.
