[KERNEL][LOS 7.1.2] Clark-Simple-Kernel - X Style (Pure) Android Development

Clark-Simple-Kernel
The goal of this kernel is to enable the necessary features to try out the Interactive governor profiles by SoniCron. HandBag kernel has worked pretty well for me too, but I get a little too obsessed with all the settings and options so I decided take a step back and keep it simple.
Overall, this kernel is based on the AICP kernel for Clark, with a few tweaks adopted from the ElementalX kernel for the Nexus 5X to allow for the Interactive governor profiles.
I’m using AICP, but it should work on any LOS based ROM as far as I know.
Features
Based on AICP 7.1.2 kernel, which is based on LOS kernel
Touchboost Toggle (adopted from ElementalX)
CPU Boost Options (adopted from ElementalX)
GlassFish 1.2 governor profile (by soniCron) set by default
AnyKernel2 installer
[1.1] Core control tweaks to set minimum big CPUs to 0 instead of 1 (better idling)*
[1.2+] Builds with UberTC 6.x and Linaro 6.3 toolchains (not sure if it's much difference but worth a try!)
[1.3+] zen I/O scheduler (not set by default, you'll have to use a kernel tuner app)
[1.5+] Westwood TCP congestion algorithm (Default)
[1.5+] iptables TTL target support
*I removed my previous core control tweak for the big cpus in version 1.4. Doesn't seem to really help battery life and may actually make it worse now that I've been using it for a while.
I also recommend trying the GlassCannon interactive governor profile and the zen I/O scheduler.

Installation
Flash Zip in Recovery
AnyKernel2 uses your existing ramdisk, so you may want to flash a fresh kernel from whatever ROM you are using before installing this.

Build Instructions
On Ubuntu 17.04:
Code:
apt install build-essential libncurses5-dev device-tree-compiler
mkdir kernel
cd kernel
wget https://dl.google.com/android/repository/android-ndk-r15b-linux-x86_64.zip
unzip android-ndk-r15b-linux-x86_64.zip
cd ..
git clone https://github.com/cmulk/Clark-Simple-Kernel
cd Clark-Simple-Kernel
export CROSS_COMPILE=<full_path>/kernel/android-ndk-r15b/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86_64/bin/aarch64-linux-android-
export ARCH=arm64
make clark-simple_defconfig
make -j4 all #replace 4 with the number of threads/cores on your build machine
cd makezip
make
#flashable zip will be created in the makezip folder

Cool ?

Can I flash it at Hanbag 2.1? @cmulk

I think it should be fine for 2.1, but the latest Handbag (2.2) adds some governor settings to the init files in the ramdisk, so those will get left behind just because of the way AnyKernel2 works.
This kernel does the same sort of thing to apply governor settings in the init files, so the same is true in the other direction (you may get left-over governor settings applied at boot that you didn't intend).
If you have any trouble, flash the full boot.img from your ROM zip (or just the whole ROM zip) and then install this kernel on top of it

Flashed at HBK 2.1, no problems.
Before I did buckup and delete kernel adiutor with twrp.
I'll check battery by night. With HBK(and others) it is always 2~5%.
Thanks for new option for us.

Interactive + ambient display still not work for me. Freezes.

I haven't seen that issue with any kernel on 1575, are you on 1572 maybe? I suppose that could be the difference...

---

Yes, xt1572 reteu. Problem was until I remember, in all custom roms.
I'm on RRemix 24.04, HBK 2.1, wheatley + bricked hotplug.
This is only one custom build where gestures work like on the stock. @cmulk

Running this on CR Droid 3.5, xt1575. Seems good so far. HBK 2.1 and 2.2 were having some bluetooth audio problems for me. Thanks for your development!

I'll have to look up all those things. 10.5 hours is very impressive

Impressive. Would you be able to pass links to the rom and other stuff you mentioned. That'd be really cool. Thanks!

---

Would you able to add bricked_hotplug governor and maple/zenfone io schedulers.

Nice! What CPU & GPU governors are you using? Any other kernel tweaks? Thanks!

I'll look into the IO schedulers, I've never really done much research/testing on how much real world difference they will make.
I plan to stay away from hotplugs: for 1. to keep it 'Simple' and 2. I've never had much luck getting noticeable improvements out of them.

What's the difference between?
clark-simple-kernel_1.2_Linaro.zip
clark-simple-kernel_1.2_Uber.zip
Are they both the same and which one should I flash?

Same kernel built using different toolchains. Flash based on preference.
