Getting started with writing a simple misc character device driver

In this section, you will first learn the required background material – understanding the basics of the device file (or node) and its hierarchy. After that, you will learn – by actually writing the code of a very simple misc character driver – the kernel framework behind the raw character device driver. Along the way, we shall cover how to create the device node(s) and test the driver via a user space app. Let's get started!

Kaiwan N. Billimoria

Kaiwan N. Billimoria taught himself BASIC programming on his dad's IBM PC back in 1983. He was programming in C and Assembly on DOS until he discovered the joys of Unix, and by around 1997, Linux! Kaiwan has worked on many aspects of the Linux system programming stack, including Bash scripting, system programming in C, kernel internals, device drivers, and embedded Linux work. He has actively worked on several commercial/FOSS projects. His contributions include drivers to the mainline Linux OS and many smaller projects hosted on GitHub. His Linux passion feeds well into his passion for teaching these topics to engineers, which he has done for well over two decades now. He's also the author of Hands-On System Programming with Linux, Linux Kernel Programming (and its Part 2 book) and Linux Kernel Debugging. It doesn't hurt that he is a recreational ultrarunner too.
