Preface
Linux is one of the fastest-growing operating systems in 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 lot of new features.
Mastering Linux Device Driver Development provides complete coverage of kernel topics such as video and audio frameworks that usually go unaddressed. You'll delve into some of the most complex and impactful Linux kernel frameworks, such as PCI, ALSA for SoC, and Video4Linux2, gaining expert tips and best practices along the way. In addition to this, you'll learn how to leverage frameworks such as NVMEM and Watchdog. Once the book has got you started with Linux kernel helpers, you'll gradually progress to working with special device types such as Multi-Function Devices (MFDs), followed by video and audio device drivers.
By the end of this book, you'll be able to write rock-solid device drivers and integrate them with some of the most complex Linux kernel frameworks, including V4L2 and ALSA SoC.
