Description

Have you ever wanted to create your very own Linux kernel module and start writing kernel code?

Well this step by step course is designed to teach you just that, we start off by installing all the dependencies we need, then we create the simplest kernel module we can a "Hello World" module that just prints "Hello World" from kernel space.

Finally we create a character device module that allows user programs to send data to us and read data from us. Think "/dev/random"

During the time I taught myself all of this many times I found articles from 2004 and they were outdated, this makes kernel development very difficult but I learnt a trick to make it all easier which I share in this course.

This course is designed to clear up all the misconceptions every detail of what we are doing is explained in depth and nothing is left out

Taught by an expert that that has created kernel modules professionally in the work place. Primarily virtual file system modules

Who this course is for:
  • Beginner Kernel Developers

Free Lessons
In this lecture we install all the kernel dependencies that we need to create this module
Here we create kernel code that just writes Hello World out to the kernel log. This is a great beginners module to get us started.

In this lecture you learn how to build character devices in the Linux kernel. Think of "/dev/random" if you try to read from this it gives you random data. We will be creating our own character device that allows us to store data and read data from our character device.
In this lecture I show you helpful resources that are important for ensuring kernel compatibility
In this lecture you will learn how the file_operations structure works in the kernel
This lecture we learn about files inodes, dentry's and inode operations
