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 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
  • 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.

    Installed the kernel using Franco Kernel Manager. The phone is frozen on the animation G

    If you're using riru then you need to update to the new version released today.

    Some people who don't have experience with how this works may see all the hotfixes and think "what's going on?" There's something SUPER important to note as a developer myself:

    Hotfix builds = very competent development. Recognizing bugs in your code and fixing them promptly may make it appear that you're making more errors than others - what it really means is you're catching more errors - not making more errors. Lastly - putting stability before ego is something not enough Devs do. A lot of Devs just leave bugs like this until their next planned release.

    Thanks very much for fixing things as they come & keeping us all informed & up to date!
