[KERNEL] [Lollipop] [G901F] [01 May.] ★ SimpleGX KERNEL v1.0.0 ★ topic

WARNING :

This KERNEL is only for Galaxy S5 Plus LTE-A (SM-G901F/kccat6) version !
You will void your warranty after flashing this ROM (knox @ 0x1)
I'am not responsible of any damage caused to your device after flashing this KERNEL



Some reading..

First of all, I would like to thanks a lot my friend @xdamc2010 for his hard investment about making a kernel finally bootable and stable kernel for our G901F and tells me his solution to finally make this kernel living. Huge kudos to him, and also to @JDizzle80 to find the solution at the same time.
SimpleGX is only looking for simplicity and stability, trying to aim for best battery life, smoothness and performance experience, than a pure stock kernel.
I still don’t qualify myself as of a real developer, but just a basic person with some android/linux knowledge already.
As always, I’m enjoying sharing my contribution here on XDA for free, which taking me a lot of time to release, so if you can offer me a little beer, I will really appreciate that.

This kernel must be only flashed over an official Samsung ROM and not AOSP/AOKP !

Feel free to include my kernel to your ROMs / Threads but please don't forget to inform/ask first via PM and credit me in your original thread.

★ WHAT TO EXPECT ★ :

(over a pure stock kernel) :

• Best battery life experience.


• Much better overall performance.


• Efficient (only proven to be good ones and not affecting battery life) tweaks.


• Stay as close as possible from stock source.

★ FEATURES (up-to-date) ★ :

Base :

• Directly based on " SM-G901F_EUR_LL_Opensource.zip" (XXU1ANH5) Lollipop Android 4.4.4 source from Samsung (for clean work and stability)


• Compiled with Linaro Cross Compiler (4.7.4 / 2014.06) toolchain (optimized for Cortex-A15) with optimization flags.


• Ramdisk from XXU1BOC4

Main :

• ZZMoove (v1.0 beta5) governor added


• ZRAM enabled with LZ4 compression and set as default


• TCP congestion control modules activated: Westwood (currently as default), reno, bic, cubic and htcp


• SElinux set to "Permissive"


• init.d support.

Various tweaks :

• Android logger disabled


• Kernel logger disabled


• CRC disabled


• Doubled min-max ReadAhead


• random: increase entropy levels (both read and write)


• slub.c: little tweak for performance improvements

Features that will NEVER be included in this kernel :

• auto-root.


• LED control.


• Charge control.


• Master sequence (screen calibrated).


• ABB (Adaptive Body Bias).
