Find the skeleton driver source, built it, try it, and modify it. There's both an overall one, and some for particular types of things like USB-UARTs. Look at some existing drivers for common things. Find an actual hardware device you want to write a driver for, take time to understand how Linux handles the mechanisms it uses (for example by looking at drivers for other things that use those mechanisms...) and then write your own.

Linux Device Drivers: Linux Driver Development Tutorial – Apriorit
February 16, 2026 - Building a Linux device driver demands in-depth knowledge of the operating system’s internals. Apart from understanding kernel architecture and memory management, your team also needs to have strong expertise in driver programming. In this tutorial, Apriorit experts provide you with step-by-step instructions on how to build a driver in Linux (starting from kernel version 6.14.0), including code samples.
How good and practical is Linux Device Drivers book?
It's pretty outdated. A lot has changed since 2.6. More on reddit.com

November 15, 2020Linux Device Drivers, O'Reilly 3rd. Ed - Out of date?
I worked through the first few chapters of this book on the latest staging tree, and it seems like it's pretty out of date. Most of the places it referred me to check out the source code, I tried searching the code for this or that function and couldn't find them where I was told to look. Not surprising given the book is 13 years behind the mainline tree. That said, if anyone knows of a more modern alternative to this text, I'd love to pick up some more knowledge about kernel internals! More on reddit.com

December 25, 2018How good is Linux Device Drivers book mainly to understand linux concepts and architecture?
find myself googling stuff which just seems a bit time consuming Welcome to the world of Linux driver development. As far as I can see, that's exactly what you have to deal with. Read all the books and fill in the gaps with online documentation and the documentation that comes with the kernel sources. More on reddit.com

January 19, 2021Best book to start with Linux drivers?
For a Uni project with a Raspberry PI, I decided to make a Kernel Mode web server (well... a demo of a kernel mode web server). I brought back from the dead kHTTPd... I looked at: https://linux-kernel-labs.github.io/master/index.html https://www.tldp.org/LDP/lkmpg/2.6/html/ https://www.kernel.org/doc/htmldocs/kernel-hacking/index.html I had to cobble together what works because some of it is very outdated... Honestly though... for the most part I've been greping the kernel source code and eyeballing it to see which functions I need to use. (Thankfully now for Kernel Threads there are functions specifically for it. Unlike back in the original kHTTPd days... o.O) I was supposed to actually add support for loading real files over the holiday break... but got distracted :D My Code... which I'll probably get back to... one year or another: https://gitlab.com/kierangrant/khttpd (Note: My code probably could be much better: Locking is probably redundant in this case with calls to kernel_accept probably could be done in worker threads...) I think this code should still compile on latest kernel (It was built on Kernels from late last year...) More on reddit.com

r/embeddedlinux on Reddit: Where to begin Linux device driver development
January 17, 2022 -
Hi, I am an engineering graduate and have been working with microcontrollers for the past 3 years. Recently I had started learning linux programming with gcc for embedded based applications on an ARM based SOC. I now want to learn linux device driver implementation. Are there some good online courses that I can use. What kind of projects can I do for learning purpose.
