About this ebook

Develop advanced Linux device drivers for embedded systems, mastering real-world frameworks like PCI, ALSA SoC, and V4L2 with practical code examples and debugging techniquesKey Features

Gain hands-on expertise with real Linux subsystems: PCI, ALSA SoC, V4L2, and power management
Apply advanced techniques for kernel debugging, regmap API, and custom hardware integration
Build robust drivers through step-by-step examples and practical engineering insights

Book DescriptionLinux is one of the fastest-growing operating systems around the world, and in the last few years, the Linux kernel has evolved significantly to support a wide variety of embedded devices with its improved subsystems and a range of new features. With this book, you’ll find out how you can enhance your skills to write custom device drivers for your Linux operating system. Mastering Linux Device Driver Development provides complete coverage of kernel topics, including video and audio frameworks, that usually go unaddressed. You’ll work with some of the most complex and impactful Linux kernel frameworks, such as PCI, ALSA for SoC, and Video4Linux2, and discover expert tips and best practices along the way. In addition to this, you’ll understand how to make the most of frameworks such as NVMEM and Watchdog. Once you’ve got to grips with Linux kernel helpers, you’ll advance to working with special device types such as Multi-Function Devices (MFD) followed by video and audio device drivers. By the end of this book, you’ll be able to write feature-rich device drivers and integrate them with some of the most complex Linux kernel frameworks, including V4L2 and ALSA for SoC.What you will learn

Explore and adopt Linux kernel helpers for locking, work deferral, and interrupt management
Understand the Regmap subsystem to manage memory accesses and work with the IRQ subsystem
Get to grips with the PCI subsystem and write reliable drivers for PCI devices
Write full multimedia device drivers using ALSA SoC and the V4L2 framework
Build power-aware device drivers using the kernel power management framework
Find out how to get the most out of miscellaneous kernel subsystems such as NVMEM and Watchdog

Who this book is for

This book is for embedded developers, Linux system engineers, and advanced programmers seeking to master Linux device driver development for custom hardware and peripherals. Readers should have C programming experience and a basic grasp of kernel concepts. Ideal for those wanting practical, project-based guidance on leveraging frameworks such as PCI, ALSA SoC, V4L2, and power management to build production-grade drivers.
