## What it is
An actively maintained edition of The Linux Kernel Module Programming Guide, updated for 5.x and 6.x kernels with working example code. It is a free book (TeX source, PDF/HTML builds) covering kernel module development, character device drivers, synchronization, memory management, and DMA.

## Use cases
- learn how to write linux kernel modules
- tutorial for writing a linux device driver
- understand kernel synchronization like mutexes spinlocks and RCU
- examples of character device drivers for modern kernels
- learn procfs sysfs and debugfs kernel interfaces
- how to pass parameters to a kernel module
- learn DMA and memory-mapped I/O in the linux kernel

## When to choose
- you want up-to-date kernel module documentation for 5.x/6.x kernels with runnable examples
- you are learning Linux kernel or driver development from scratch
- you need a free, well-structured reference on kernel programming interfaces

## When to avoid
- you need documentation for kernels older than 5.x
- you want general Linux user-space programming rather than kernel-space development
- you need driver development for non-Linux operating systems

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: operating-systems, developer-tools, tutorials, documentation
- platform: cross-platform
- tags: linux-kernel, kernel-modules, device-drivers, book, c, kernel-programming, linux
