If you want to improve your skills to develop custom device drivers for your Linux operating system, Mastering Linux Device Driver Development can provide complete coverage of kernel topics, including video and audio frameworks. With this comprehensive guide, you can work with some of the most complex and impactful Linux kernel frameworks such as PCI, ALSA for SoC, and Video4Linux2 to explore and adopt Linux kernel helpers and unlock the Linux kernel’s potential.

The book starts by introducing Linux kernel concepts for embedded developers and then progresses to the more advanced topics. You can easily understand the Regmap subsystem to manage memory accesses and work with the IRQ subsystem, learn about the PCI subsystem, write reliable drivers for PCI devices, and build power-aware device drivers using the kernel power management framework. Additionally, you can find out how to work with miscellaneous kernel subsystems such as NVMEM and Watchdog and how to write full multimedia device drivers.

The book is structured to help you adopt a practical approach to customizing your Linux environment using best practices. With expert tips and best practices, you can master the art of developing customized device drivers for your embedded Linux systems.
