This is a no-frills custom kernel for the Pixel 2 and Pixel 2 XL designed to be used with the stock ROM and custom Android 10 ROMs. It's intended to be a simple replacement for the stock kernel that brings several under-the-hood enhancements. This kernel is not meant to be customized by users.

Changelogs for each update can be found in the 2nd post of this thread.

Features:

Compiled with GCC 10.2 from the Arch Linux repository

Built with Link Time Optimization (LTO) for improved overall kernel performance

Built with Dead Code Elimination (DCE) to shrink the kernel's size by removing unused code

Removed lots of excessive bloat (improves security and performance)

Simple LMK, a custom low memory killer that improves memory management

Fast fingerprint unlock and screen power on

Improved touch latency

Optimized CPU frequencies and EAS energy model for improved performance and battery life

Haptic feedback disabled while the camera is in use

Hall sensor disabled by default (it can be re-enabled by flashing the optional enable-flip-cover-support zip)

Removed maximum screen brightness limitation

WireGuard, a next generation secure VPN tunnel

Passes SafetyNet bootloader unlock check

Improved overall system fluidity and graphics performance

Improved stability

Westwood+ TCP congestion algorithm

Vibration strength control

Many other miscellaneous improvements not listed here

Installation instructions:

First of all, this kernel comes with a custom dtbo so DO NOT FLASH A DIFFERENT DTBO AFTER INSTALLING THIS KERNEL! To install this kernel, simply download and flash it in a custom recovery. Do the same when there is a new update available.

Note that there are some caveats if you'd like to flash Magisk and/or TWRP in addition to this kernel. If you want to flash TWRP, then you must flash it after flashing the kernel first. If you want to flash Magisk, then you must flash it after flashing both the kernel and TWRP first. You don't need to re-flash Magisk after every kernel update though.

This is the order in which the kernel, TWRP, and Magisk should be flashed:

Kernel -> TWRP (optional) -> Magisk (optional)

The optional enable-flip-cover-support zip can be flashed at any point of the installation process. It does not need to be re-flashed after each update.
