Hello again,

This is my work on the stock Marshmallow Kernel for Zenfone 2, based on the officially released ZF2 kernel source code.

Please note that I do my testing on a ZE551ML 4GB 2,3GHz

Note: This kernel works ONLY on stock based versions!​

Features:
Based on Zenfone 2 V4.21.40.184 kernel source (completely from scratch)
Built with gcc4.9 toolchain
UC to 333MHz
Touchboost input event handler
Added the following CPU governors:
- Lionheart
- Bioshock
- Yankactive
- TheSSJactive (Yankactive with hotplugging)

Added IO schedulers:
- sio
- zen
- vr
- fifo
- sioplus (credits to @boype, fixed afterwards for zf2 by me)
- fiops
- working ROW scheduler!!!
- deadline

Added TCP congestion algorithms:
-BIC
-CUBIC
-WESTWOOD
-HSTCP
-HYBLA
-HTCP
-VEGAS
-VENO
-SCALABLE
-LP
-YEAH
-ILLINOIS

Approx. 30% faster due to CRC disabling and auditing
Power efficient Work queues
Powersuspend
Dynamic FSync
Set minimum brightness to 2 instead of 15 percent (changeable via kernel adiutor, please set it to 1 there, otherwise your screen is pretty much black)
exfat support (no fuse, all credits to @Dorimanx, automounting of devices fixed by @sorg)
Sweep2Sleep (all credits to Lord Boeffla)
frandom RNG
F2FS support
ZRAM
WLAN Wakelock reducer


More to come:
Init.d

If I should find the time also:
BLX
A separate KVM build
Compiling with another Toolchain

How to install:

1st pre-requisite: Unlock your Bootloader
2nd pre-requisite: Use the stock Marshmallow ROM ;-)
3rd pre-requisite: BACKUP!!!

Download the flashable anykernel zip here:
Drive

Flash it via TWRP and reboot. The Anykernel zip preserves whatever modification you already have (xposed, root,...) and just replaces the needed parts :good:

Project T, reborn! It's incredible to see this project alive agan!
@TheSSJ, about F2FS: it supports mixed setups (F2FS /data and ext4 /system and /cache) or only F2FS-all setups?

@TheSSJ

For some reason, after flashing, the kernel does not install.

I reboot to twrp, dirty flash WW134 ROM, flash supersu, flash xposed, flash twrp and flash this kernel. Wipe cache and d.cache.

Reboot and it stock kernel.

I tried 2nd time. Flash kernel in twrp and it still stock kernel.

Cool it everyone, I think it's just a misunderstanding ;)
I have uploaded a flashable zip for now as Anykernel doesn't work as I want it to work ^^

At the moment this can be only flashed by people
WITH root and
WITHOUT xposed

After flashing the kernel, then you can re-flash xposed, this should work then

Thanks! downloading...

EDIT:
After flashing the kernel the system became unbootable. It boots into recovery after "reboot system".

Okay, did you have xposed installed? Could you please try to remove xposed and just flash the kernel without it? This Anykernel thing seems to be the only available option...

Maybe I'm being paid to break xposed :p
I just need to take the time to see where the script goes wrong (by the way,I took your anykernel as base :laugh: )
Will test it line by line on my linux machine today :good:

    Battery shows the phone is about 95% of the time in deep sleep. Is this normal?

    I am losing 1-2 % per night. Yes, the deep sleep rate is normal...as our phone model becomes older and older, the battery is beginning to struggle more and more...it's pretty normal

    How can i install SuperSu(chainfire) on stock rom(with this kernel) ?

    I flashed the kernel and restarted (no SuperSu work)
    I flashed Magisk7 fixed for ZF2 and install Magisk Manager.apk
    I flashed supersu r277 fixed for ZF2

    And no root..... I dont know what's happening :(

    All sources are in THIS post
    Click to expand...
    Click to collapse

    Can't tell you...I was on stock when I rooted my phone. Only afterwards I flashed my kernel. Since then I am still rooted when I flash an updated kernel version...Maybe you should start from scratch and first root and flash magisk, THEN flash my kernel

    Implemented and building right now. Can*t tell if the sensor problems are fixed in this version though...12 files or so were updated, see my git account for info

    EDIT: Uploaded version 1.5, hopefully the sensors are fixed for the brazilian users, too

    Not that I know of, normally someone would just need to upload his MM system.img, the rest should be the same

    EDIT: Version 1.4 is out:
    - backlight is configurable again (super simple patch)
    - Mechanism to avoid entropy depleting (aka generating random numbers as needed)

    Will have a look for more cool optimizations
