by Kaiwan N. Billimoria: This is currently the most recommended modern alternative. It is based on Linux Kernel 6.1 (LTS) and provides a comprehensive guide to kernel internals and writing modules.
The story of Linux Device Drivers, 4th Edition is a legend within the programming community—not because of its content, but because the book itself has never been officially released. The Legend of the "Ghost Edition"
As of the current date, O'Reilly Media has not published a printed, commercially available "Linux Device Drivers, 4th Edition" authored by Corbet, Rubini, and Kroah-Hartman.
Published in 2005, the Third Edition remains a foundational text for kernel developers. It introduced core concepts that are still relevant today: linux device drivers 4th edition pdf
While there is no official book, many developers have updated the code samples from the Third Edition to compile on modern kernels. If you own the Third Edition, you can use it for the conceptual theory (which remains largely the same: interrupts, memory mapping, concurrency) while using updated GitHub repositories for the code syntax.
The book will need to cover the transition from the legacy methods of 2.6 to modern kernel frameworks. This includes advanced concurrency managed workqueues, the updated lockless buffering systems, and modern lock primitives. 2. Device Tree and Driver Model

If you are on a budget, you can often find the Second Edition PDF legally. While outdated regarding the Kernel API, the concepts of how devices talk to the CPU (ISA, PCI, USB) remain valuable educational foundations.
The book has been assigned various release dates over the years, leading many in the community to label it "vaporware."
For over two decades, the Linux Device Drivers (LDD) series has served as the canonical bible for anyone looking to move beyond simple scripting and into the raw, powerful world of kernel programming. Among the three major editions published by O’Reilly Media, the holds a unique, almost mythical status. Despite being released in 2005 (covering the 2.6.10 kernel), it remains the most sought-after version, with the search query "linux device drivers 4th edition pdf" generating millions of requests annually.

For years, rumors have circulated about a Fourth Edition covering the 3.x and later kernels. However, the authors—specifically Greg Kroah-Hartman and Jonathan Corbet—have stated in various interviews and mailing lists that the task of writing a static book for such a rapidly changing codebase as Linux is nearly impossible. By the time a book goes to print, the kernel APIs have often changed.
