## What it is
The Raspberry Pi fork of the Linux kernel source tree, containing patches and drivers for Raspberry Pi hardware. It is the upstream source used to build the kernels shipped with Raspberry Pi OS.

## Use cases
- build a custom kernel for Raspberry Pi
- add or patch a device driver for Pi hardware
- debug kernel issues on Raspberry Pi boards
- track Raspberry Pi-specific kernel patches across releases
- compile the kernel for a headless Pi project

## When to choose
- you need kernel-level changes or drivers specific to Raspberry Pi hardware
- you are building a custom or embedded Linux system for Pi boards
- you want to contribute Pi kernel patches upstream

## When to avoid
- you just want a working OS image - use Raspberry Pi OS instead
- your issue is with userspace software or firmware rather than the kernel
- you need a general-purpose kernel for non-Pi hardware

## Facets
- artifact type: library
- maturity: active
- function: embedded, programming-language
- domain: operating-systems, embedded-systems, hardware
- platform: embedded
- tags: linux-kernel, raspberry-pi, kernel-source, device-drivers, firmware, linux, arm
