Sobre este producto

Learn how to write real, modern FreeBSD device drivers from scratch. No prior experience required.This beginner-friendly, hands-on guide takes you on a complete journey into the world of FreeBSD driver development, one clear step at a time. Whether you’re a curious student, aspiring systems programmer, embedded developer, or open-source enthusiast, this book gives you the practical skills and foundational knowledge to master kernel programming at your own pace.You'll start from the very beginning, learning the UNIX environment and the C programming language before diving into the FreeBSD kernel itself. Guided by clear explanations, carefully annotated code, and real-world examples, you'll build your first driver in a safe virtual lab and grow it into a fully functional production-grade module. What You’ll LearnHow to install and configure a FreeBSD development environment using virtualisationThe fundamentals of UNIX, shell usage, and kernel-space C programmingHow FreeBSD device drivers are structured, built, and dynamically loadedHow device files work and how drivers communicate with user-space applicationsTechniques for handling input/output operations and buffering efficientlyHow to manage memory in the kernel using malloc(9) and uma(9)Safe concurrency and synchronisation with mutexes, condition variables, semaphores, and task queuesHow to write drivers for PCI, USB, and serial devices including interrupt and DMA handlingStrategies for deferred and asynchronous work using timers and kernel tasksPower management support and how to make your driver energy-awareDriver development for virtual environments (like bhyve and jails) and embedded platforms (using FDT/Device Tree)How to profile, debug, and trace kernel drivers with tools like printf(9), DTrace, and ktraceBest practices for secure driver development, including input validation and safe memory handlingHow to design portable and maintainable drivers that support multiple hardware configurationsAn introduction to reverse engineering undocumented hardware for driver developmentHow to package and submit your driver to the FreeBSD Project and contribute back to the communityHow the Book Is OrganisedThis book guides you step by step from beginner to expert in FreeBSD device driver development.Part I – Foundations: Set up your FreeBSD environment and learn the essentials of UNIX, the terminal, and C programming, perfect for complete beginners.Part II – Driver Basics: Write your first driver and learn how device files, I/O, buffers, and synchronisation work in FreeBSD.Part III – Low-Level Hardware: Dive into real hardware with PCI, interrupts, DMA, and power management techniques.Part IV – Kernel Integration: Debug your code, work with USB and serial devices, and build drivers that integrate cleanly with the FreeBSD kernel.Part V – Mastery Topics: Tackle modern challenges like virtualisation, security, embedded systems, async I/O, and contributing your drivers to the FreeBSD Project.About the Author Edson Brandi is a long-time FreeBSD contributor and committer with over 30 years of experience in open-source and infrastructure. He helped build the Brazilian FreeBSD community and is one of the founders of FUG-BR. Professionally, he has led technology and infrastructure teams at companies like StoneCo and Teya. Starting his journey with FreeBSD as a chemistry student, Edson wrote this book to give back to the community that helped shape his career and to make kernel development accessible to all.What begins with curiosity can lead to mastery. Start here, and build real-world skills that few developers ever master.
