[KERNEL] [Oreo-8.1] [libra/aqua] HateKernel-2.0 -UBERTC-5.3.x

[kopter36]

Introduction

HateKernel is a custom kernel compatible with libra/aqua and on LineageOS 15.1-based ROM (Oreo 8.1.0). This kernel source are forked from Cozzmy13's source (CAF) and are made to improve performance, battery life, features and stability of our device. Obviously, I can't guarantee all of those claims at once due to the fact that there is a trade-off among them, so its up to you for applying tweak or setting-up your device based on your usage criteria.

Damn! I'm too lazy to post any. :silly:

Features

-Boeffla wakelock blocker.
-FAUX sound control.
-KCAL advanced color control.
-CPU boost & input-boost. (off by default)
-Kernel samepage merging. (off by default)
-Power-efficient workqueue. (on by default)
-Disable storage CRC check. (reduce IO overhead)
-FSync on/off. (on by default)
-250Hz tick timer-interrupt & dyntick tickless-idle. (may help with battery and UI lagginess? I'm not sure.)
-Added CPU Governor - relaxed, blu-active, despair, zzmoove, elementalx, wheatley, impulse, bioshock.
-Added IO-Scheduler - fiops, sio, sioplus, zen, vr, maple.
-Exposed all TCP congestion algorithm.
-Proper undervolt. (untweakable. Hardcoded in kernel. Blame QCom)
-Compiled with UBERTC-8.x.x -O2 flag.
-A few more optimization.

Installation instruction

Required - TWRP recovery latest version & Nougat-bootloader.
NOTE: For AnyKernel2 flashable zip, I highly recommend to flash your stock ROM's boot.img first.

Flash via 'fastboot':
1) Download 'HateKernel-x.x.img'
2) Put the image in same folder as fastboot executable.
3) Run thru command "fastboot flash boot HateKernel-x.x.img"

Flash via TWRP recovery (boot.img):
1) Select install and change mode to "Flash Image" in TWRP.
2) Flash 'HateKernel-x.x.img' in 'boot' partition.
3) Obviously, reboot.

Flash via TWRP recovery (AnyKernel zip) RECOMMENDED
1) I think you should know how at this point.
2) Install as usual.

+ Preliminary info.

- Kernel in .img format are only compatible with Lineage-15.1 by Cozzmy13 ONLY. Don't flash it on other ROM even from the same source.

- HateKernel-1.5_r2 and up currently had issue with some device won't be able to boot. I'm currently still working on it.



+ Download info.

- Testbuild : There is 2 version (Lineage-15.1 stock & HateKernel build). Please test both version from lower-number to highest and report back which one is working + state last Stable-release of HateKernel that is working before.

- Experimental release is essentially a beta version but have been tested by me, but sometimes it might not working reliably with certain ROM+variant(libra/aqua).

- Stable release, as the name imply, mostly always working and have no major bug. This version have been tested extensively to avoid complaint from users and headache for me

Thank you so much for every feedback.

Whoa, can't wait for this to be released and given a bunch of customization soon

DL link posted. Try it out

 

[hanuraiga]

long time not see a custom kernel, cool
so if you use kernel based on Los 15.1, can I use this for other roms based los15.1 kernel?

 

[IcyGlacial]

nicee, will this compatible with others 15.1 based?

It should work. I've no idea if my kernel will broke something on other LoS-15.1 based rom as I've only tested it on unofficial LoS15.1 by Cozzmy13 but sure, try it and if something breaks, I'll try my best to fix it. :good:

 

[caxwan]

Just try installing on AEX rom, but not explore more.

i've got bootloop on NOS....

 

[ClaviluX]

AEX on libra? Can you give me the thread link?

Sure, here the thread

[kopter36]

i've got bootloop on NOS....

I can see that rom used Cozzmy13 kernel source which is the same tree of my kernel. Probably something changed in boot.img ramdisk for NOS kernel. I try to make anykernel patcher tonight.

Sidenote : HateKernel 1.3 already compiled with GCC 5.3.1 (ubertc-5.3.X) and booted up properly. Will released tonight with some other changes.

Thanks guy! You are really great!

Awesome... I'll be waiting

 

[flammenwerferx]

Is this kind of kernel features only available on kernel version 3.18.xx or is it also available on kernel version of 3.10.xxx

 

[kopter36]

Is this kind of kernel features only available on kernel version 3.18.xx or is it also available on kernel version of 3.10.xxx

Most of those features are not limited to 3.18.xxx kernel. I've seen most of it implemented on Nexus 5X's custom kernel which share same kernel version with our device with the only exception is Qnovo charging driver. In fact, I've seen some of those features implemented on 3.10.9x which arent upstream to latest version at all.

 

[kopter36]

HateKernel-1.3 is up

Changelog ;

-upgrade compiler to UBERTC-5.3.X (GCC-5.3.1)
-revert overclocking code until I found (if possible at all) working code
-proper undervolt to keep thermal-throttle a bit manageable

P.s: Not much changes in this version because I'm currently on holidays. Regarding kernel-patcher (AK2/lazyflasher), I'm currently still learning to do that. Very sorry guys. Development for more feature and upstream will continue soon.


To-do list ;

-upstream with latest CAF tag for msm8992
-upstream security patch
-Boeffla wakelock blocker
-backport zRam, F2FS and ext4 driver
-Adreno idler

I'm open to any suggestion to add other feature, just make sure its reasonable. Would be a great help too if you can point me to the commit if available.

 

[caxwan]

Thanks @kopter36
HateKernel 1.3 intalled on my phone.
AEX Rom, without trouble on booting.

Well, I'mma just suggesting these

1. KCAL Advanced Color Contol [with satutation, contrast and etc. Control]
2. Faux Sound Control [this really useful especially if somebody is experiencing a hissing noise on their headset, so they can reduce the output volume through this control]
3. Intelliplug or any hotplugging [only if it's really necesarry]
4. Adreno idler / booster of course (You've mentioned)
5. Upstreaming to the latest CAF (You've aforementioned)
6. ZRAM LZ4 Backport (On your to-do list)
7. Some kind of power efficient workqueue maybe
8. So-called boeffla wakelock (if i ain't mistaken the name)



PS : Anyway, undervolting seems working flawlessly, I've never reached 50°C now on normal chatting usage (usually it is around 50-55°C after one hour usage)
