Default [KERNEL][14/07] NX-Kernel v1.4.2

STOP! This kernel supports ONLY CM10.1.x, AOKP-4.2.2, PA-4.2.2 ROMs.
It won't work on Samsung Jellybean/ICS, AOSP ICS, CM9 or CM10.
Carbon ROM may be incompatible with NX-Kernel.


✯ ✯ ✯ ✯ ✯ NX - KERNEL ✯ ✯ ✯ ✯ ✯

... because we deserve more ...

Description:

Welcome folks! NX-Kernel is highly advanced kernel for pure android ROMs. It is under continuous development with new features along with integration of new linux kernel.
NX-Kernel auto-installs NXTweaks app. This app based on STweaks by GokhanMoral. This app is core of this kernel. It will help you to fine-tune and get total-control over your kernel.
Touch-sensitivity, GPU, CPU, Kernel, mDNIe, Charging currents, etc already tweaked and controllable by NXTweaks.
Dynamic Tweaks enabled by CortexBrain will help you to save power and increase performance at the same time! It gives dynamic tweaks based on screen on or off.
Use it to experience it! You can read more features below.

One more thing, I would like everyone to know - Only Kernel is not responsible for your device.
Device configuration, ROM, installed app, usage plays important role!
If you believe kernel is not stable, move on because it's probably you who are unaware how to use kernel.

Features:

✔ Kernel version updated to 3.0.86
✔ Linaro Build Kernel (Much better performance, search on XDA to know more)
✔ Auto-installs kernel tweaking app "NXTweaks" based on STweaks source by GM.
✔ Governors included: HYPER (default-tested), HYDRXQ, Lulzactiveq, Pegausq, SmartAssv2, Adaptive, Conservative, Interactive, Ondemand, Userspace, Powersave, Hotplug, LagFree, Nightmare, Intellidemand
✔ I/O Schedulers included: BFQ, CFQ, NOOP, DeadLine, ROW(default), SIO, ZEN
✔ Overclocked to 1.6GHz (1.4 GHz default, overclocking is optional).
✔ GPU Control interface. Can be overclocked upto 400 MHz!!!
✔ Charge Control Interface. Find it NXTweaks app to increase/decrease charging current.
✔ mDNIe Screen Control Advance Interface
✔ CPU Control Interface
Sound Control Interface - Sound Boost for mic, headphone and more Removed on demand.
✔ Charge Control Interface - Increase/Decrease charging current for USB, AC and Misc
✔ Massive script for kernel/ROM management. It's will work auto and set lots of tweaks: NET tweaks, GPU tweaks, CPU management, Deep Sleep Tuning, Charging states, and more! We call it CortexBrain!
✔ Swappiness is set to 0 in zram-swap script. With ZRam is in action while you run out of memory.
✔ CortexBrain integrated - Gives dynamic tweaks on screen on/off
✔ ZRam Settings on-the-fly
✔ Fully customized RAM-DISK to inherit more optimization
✔ Working FM-Radio with Spirit FM app.
✔ Optionally loadable XBOX controller, USB-to-Serial and many more modules.
✔ Fuel-Gauge Reset
✔ Low Sound fixed. Enjoy more gain to your music and other media.
✔ Frequency adjustable under Performance Control or any relative app.
✔ Battery friendly. Less wakelocks.
✔ Init.d script tweaks: Smart & Fast Zipalign, Database compaction and optimization
✔ UMS and MTP mode can be selected on-the-fly from NXTweaks
✔ No depletion of entropy pool - Increases performance of app loading.
✔ Entropy Tweaks
✔ Philz Touch recovery - Latest
✔ Dyanamic FSync -- Disabled for now
✔ Supports Tegrak 2nd core app for hotplugging.
✔ Ultra KSM from 3.9.y kernel.
✔ Many fixes & upgrades viewable on github source.

How to obtain optimum battery life?
▷ If you are comparing/complaining battery life on NX, CM, touchwiz kernels, NX is not for you, stay with CM/touchwiz.
▷ NX Kernel is more performance driven and little less battery saver compared to CM Kernel.
▷ This is because we use 16 dynamic frequency steps, high performance governor, and advance features.
▷ In case you overclock CPU or even GPU, you are tend to have less battery life. So don't overclock if you wish battery over performance.
▷ Do not undervolt too much, it starves your device and may have adverse effects like SOD/freeze/soft reboot.
▷ There is a app named 'Battery Widget Reborn', use it and enable Night Mode Power save.
▷ One more app 'Fast Dormancy Toggle for I9300', use it if your network doesn't provide dormancy. Google for more info.
▷ Don't keep monitoring battery every now and then. Treat it good.
▷ Have full battery-charge cycles 2-3 times in a week which means when battery drains below 20%, charge it to 100% without interruption.
▷ Sign out google talk / hangout if you don't use, it drains power.
▷ Wakelocks is another enemy if they come unnecessarily from installed apps. You can monitor with very good app named 'Better Battery Stats', it's paid app.
▷ Use Performance/Extreme Performance profile from NXTweaks only when required, restore default whenever possible.
▷ It is highly recommended to turn off AUTO SYNC option day time and use it only when charging.
▷ Even your touch-screen drains power when screen on. Never use full brightness. Use auto-brightness or low brightness.

If you follow these advice atleast for a week, you will have optimum battery life!

In case you have SOD (Sleep of death) or SOFT Reboot, please check following:
✔ Minimum Frequency should not be less than 200 MHz
✔ You are using stock settings for voltages and haven't undervolted
✔ Default Governor is stable one, recommended to use for good stability
✔ You haven't installed or have activated any apps or scripts which interrupt settings of NXTweaks
✔ Similarly, do not use apps that implements profiles like 'screen off' , 'on call', etc

WiFi Issues? Follow the below steps:
▷ Open WiFi Advanced Options. In region, select any region and then select US. This may not be available on all ROMs.
▷ Open NXTweaks, under Tweaks Tab, tap on "Clear WiFi Lease" button.
▷ Under Charging Currents Tab, tap on "Reset Fuel Gauge"
▷ Reboot in recovery, Fix permissions.

If you still face issue, clean install good compatible AOSP ROM + Gapps, (optionally flash NXKernel), follow above steps.
If issue persists, you may need to get hardware checked.


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

Default Governor:
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.

Default IO Scheduler:
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.

My Recommendations:

Recommended Governors: HYPER > NeoX > SmartAssv2 > LulzActiveq > Nightmare > Intellidemand > Others
Recommended Schedulers: ROW > ZEN > BFQ > CFQ > SIO > NOOP > Other

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 NX 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.

Running the kernel on (unofficial) Mad Cow Rom. First impression: Good!

Great to have a AOSP-Kernel with Philz-Recovery!

Small issue: If you select Misc nandroid settings in Backup and Restore, it's not working. Backup and Restore Menue appears again.

That's because PhilZ recovery is not fully open source.
We will switch to better one.
