This is a no-frills custom kernel for the Pixel 4 and Pixel 4 XL designed to be used with the stock ROM and custom Android 11 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 11.2 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
  • Optimized CPU frequencies and EAS energy model for improved performance and battery life
  • WireGuard, a next generation secure VPN tunnel
  • Passes SafetyNet bootloader unlock check
  • Improved gaming performance
  • Improved overall system fluidity and graphics performance
  • Improved stability
  • Many other miscellaneous improvements not listed here

Source code:
11.0.0-sultan branch: https://github.com/kerneltoast/android_kernel_google_floral

Credits:
  • zx2c4 (for WireGuard)
  • osm0sis (for AnyKernel3)
  • kdrag0n (for quite a few useful commits)
  • If your name should be here and it isn't, then replace my camera with a OnePlus 3

Installation instructions:
You can flash this kernel normally in TWRP, LineageOS recovery, or Franco Kernel Manager.
