FreeBSD Device Drivers: From First Steps to Kernel Mastery is a free, open-source book that takes you from "I've never written kernel code" to "I can write, debug, and submit production-quality FreeBSD drivers." It is a guided course rather than a reference, structured around 38 chapters, 6 appendices, and dozens of hands-on labs that compile and load on a real FreeBSD 14.x system.
The book is aimed at readers who are willing to learn rather than are already qualified. It begins with UNIX fundamentals and the C language, walks step by step through every concept the kernel will demand of you, and only then opens the door to driver development. By the time you reach DMA, interrupts, and PCI work, the vocabulary feels earned, not imposed.
