# The Linux Kernel Module Programming Guide
This project keeps the Linux Kernel Module Programming Guide up to date, with [working examples](examples/) for recent 5.x kernel versions.
The guide has been around since 2001 and most copies of it on the web only describe old 2.6.x kernels.
The book can be freely accessed via https://sysprog21.github.io/lkmpg/ or [latest PDF file](https://github.com/sysprog21/lkmpg/releases).
The original guide may be found at [Linux Documentation Project](http://www.tldp.org/LDP/lkmpg/).
You may check other [freely available programming books](https://ebookfoundation.github.io/free-programming-books/books/free-programming-books.html) listed by The [Free Ebook Foundation](https://ebookfoundation.org/) or [Linux online books](https://onlinebooks.library.upenn.edu/webbin/book/browse?type=lcsubc&key=Linux) collected by [The Online Books Page](https://onlinebooks.library.upenn.edu/).
## Getting Started
### Summary
1. Get the latest source code from the [GitHub page](https://github.com/sysprog21/lkmpg).
2. Install the prerequisites.
3. Generate PDF and/or HTML documents.
### Step 1: Get the latest source code
Make sure you can run `git` with an Internet connection.
```shell
$ git clone https://github.com/sysprog21/lkmpg.git && cd lkmpg
```
### Step 2: Install the prerequisites
To gernate the book from source, [TeXLive](https://www.tug.org/texlive/) ([MacTeX](https://www.tug.org/mactex/)) is required.
For Ubuntu Linux, macOS, and other Unix-like systems, run the following command(s):
```bash
# Debian / Ubuntu
$ sudo apt install make texlive-full
# Arch / Manjaro
$ sudo pacman -S make texlive-most texlive-bin
# macOS
$ brew install --cask mactex
$ sudo tlmgr update --self
```
Alternatively, using [Docker](https://docs.docker.com/) is recommended, as it guarantees the same dependencies with our GitHub Actions wokrflow.
After install [docker engine](https://docs.docker.com/engine/install/) on your machine, pull the docker image [twtug/lkmpg](https://hub.docker.com/r/twtug/lkmpg) and run in isolated containers.
```shell
# pull docker image and run it as container
$ docker pull twtug/lkmpg
$ docker run --rm -it -v $(pwd):/workdir twtug/lkmpg
```
[nerdctl](https://github.com/containerd/nerdctl) is a Docker-compatible command line tool for [containerd](https://containerd.io/), and you can replace the above `docker` commands with `nerdctl` counterparts.
### Step 3: Generate PDF and/or HTML documents
Now we could build document with following commands:
```bash
$ make all # Generate PDF document
$ make html # Convert TeX to HTML
$ make clean # Delete generated files
```
