## What it is
Updated versions of the example drivers from the book 'Linux Device Drivers 3rd Edition', maintained so they compile against recent Linux kernels. It serves as a hands-on learning resource for kernel driver development.

## Use cases
- learn how to write Linux device drivers
- compile LDD3 book examples on modern kernels
- study kernel module programming with working sample code
- test example drivers against recent kernel versions
- set up a kernel driver development environment with Eclipse CDT

## When to choose
- you are learning Linux kernel driver development from the LDD3 book
- you need the original book examples updated to build on recent kernels
- you want reference C code for character devices, memory allocation, and kernel APIs

## When to avoid
- you need production-ready device drivers for specific hardware
- you are developing drivers for operating systems other than Linux
- you want a maintained driver framework rather than educational examples

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, embedded
- domain: operating-systems, embedded-systems, tutorials, developer-tools
- platform: c
- tags: linux-kernel, device-drivers, ldd3, kernel-modules, book-examples, linux
