catpieleaf/kernel-p03

A zero-misplay kernel with Firelzrd, CachyOS, TKG, XanMod, Clear Linux patches and more, built from Fedora Koji SRPMs.

This repository provides a set of tools to automatically build, patch and compile the Linux Kernel from Fedora Koji SPRMs, with a selection of patches and configurations aiming for a better system responsiveness.

F E A T U R E S

• Built on top of Fedora Koji Sources with Fedora's baseconfigs
• Local Automatic Secureboot Signing and Key generation (For nvidia drivers too!)
• NVIDIA-Open Kernel Modules support
• ThinLTO or FullLTO (Copr builds are ThinLTO)
• LRU-Marie
• Nap CPUIdle governor
• Per-CPU ISA Optimizations (Copr only provides Generic x86-64v3 and v2)
• 750hz tickrate
• Built with LLVM + O3 + Polly Clang + Mimalloc
• BORE scheduler
• BBRv3 congestion control and FQ qdisk
• OpenRGB Support
• AMD HDMI-FRL Support
• xConfig and nConfig during build
• ADIOS I/O Scheduler
• Handheld support (ROG Ally, Steam Deck, etc)
• VHBA and AUFS support
• Microsoft Surface support
• Piece-Of-Cake (POC) CPU Selector
• Dynamic PREEMPT (Lazy by default)
• Passive intel_pstate and amd_pstate
• Catastrophic Misplay Screen: A custom P03-themed QR-Code panic screen for those rare, fatal errors.
• And many more!

If it does not detect x86_64_v3 support, do not install the default kernel. Otherwise, you will end up with a non-functioning operating system! You should install the gcc x86_64 v2 kernel by running sudo dnf install kernel-p03-gcc
