Some reading..

Welcome to SimpleGX kernel ! a kernel that aims for simplicity, stability, better performance, smoothness and battery life over a pure stock kernel.

This kernel is designed for people who are (like me) bored to flash kernels which integrate tons of unneeded things.

Main goals of it, is to stay MUCH closer to stock than every kernels shared here and almost not to be a “custom kernel” on its own. So beware, no exotic stuffs here !

No need for any third app or whatever to control this kernel. Just "flash-n-joy" ! this is how I always liked thing.

Keep in mind that this kernel has been designed for my daily use first.

As always, I'm enjoying sharing my contribution here on XDA for free, which taking me a lot of (my free) time to test before releasing. So, if you can offer me a little beer, it will be really appreciated!

This kernel must be only flashed over an official Google Pixel 3/XL firmware !

​

★ WHAT TO EXPECT ★ :​

(over a pure stock kernel)

:

Slightly better battery life

Slightly better performance

Include only efficient (but definitely not experimental) tweaks

Stay as close as possible from pure stock source

★ FEATURES (up-to-date) ★ :​

Base

:

Always directly based from latest available "android-msm-crosshatch-4.9-pie-qpr2" Android source from Google (for clean work)

Compiled with stock Google (4.9.x / CLANG) toolchain with stock LTO/CFI options (for best stability and security)

Featuring AnyKernel3 (for all ramdisk compatibility)

Stock Linux

Main

:

Completely optimized stock 'cfq' I/O scheduler

All TCP congestion control modules activated with Westwood currently as default

mmc/core: disabled CRC check

tcp_output: set initial TCP window size to 64K

fs: default to noatime

WireGuard support (thanks to [MENTION=5434776]zx2c4[/MENTION])

Removed verify and forced encryption + patched SafetyNet flags to pass CTS

Some miscellaneous tweaks, fixes, and security patches

Various tweaks

:

Full changes to be discovered directly in my Github source below

Features that will NEVER be included in this kernel

:

adding any other governor/IO schedulers than those stock

root/busybox auto-installation

CPU/GPU overclocking/undervolting

KCAL

adreno idler

state_notifier

any upstream of Linux kernel

dual-boot

etc

★ PREREQUISITE ★ :​

An unlocked Bootloader

An Android Pie firmware

Optional : to control some kernel options, you can install Kernel Adiutor)

★ INSTALLATION PROCEDURE ★ :​

METHOD 1 : testing kernel without real flashing

Backup

everything

you need (internal & external)

Unlock your bootloader (if not already done)

adb reboot bootloader

Extract 'Image.lz4-dtb' from kernel ZIP (SimpleGX_KERNEL_Pixel3-XXX_vX.X.zip)

fastboot boot Image.lz4-dtb

Enjoy ! (but beware.. kernel will be lost after any single reboot!)

METHOD 2 : flashing kernel classically

Backup

everything

you need (internal & external)

Unlock your bootloader (if not already done)

adb reboot bootloader

fastboot boot twrp-3.2.3-0-blueline.img (or better)

ADB sideload SimpleGX_KERNEL_Pixel3-XXX_vX.X.zip

OPTIONAL (if you want to root the kernel) : ADB sideload Magisk-v18.1.zip (or better)

Enjoy ! (kernel will stay after any single reboot)

★ Frequently Asked Questions (FAQ) ★ :​

How can I update my SimpleGX kernel version ?

- Just make a dirty flash over it. If there is a special thing to do, then it will be precised directly into the announce.

How can I go back to stock kernel ?

Just flash back your full usual firmware back.

Is there a LineageOS (LOS) version of you kernel ?

No, and there won’t be any.

My battery is draining like hell, what's wrong ?

As [MENTION=6842057]nathanchance[/MENTION] perfectly said for his kernel: "The kernel doesn't drain any battery, use an app like BetterBatteryStats to figure out what app is screwing with your phone".

Also, generally, I remarked that wiping cache+dalvik between updates may drain a lot for the percentage left and the first cycle. Anyway, be sure to make

at least

two full cycles (from 100% to 0%) before judging battery life for any kernel.

How to recover excellent battery life ?
