Описание: Learn to develop customized device drivers for your embedded Linux system About This Book - Learn to develop customized Linux device drivers - Learn the core concepts of device drivers such as memory management, kernel caching, advanced IRQ management, and so on. - Practical experience on the embedded side of Linux Who This Book Is For This book will help anyone who wants to get started with developing their own Linux device drivers for embedded systems. Embedded Linux users will benefit highly from this book. This book covers all about device driver development, from char drivers to network device drivers to memory management. What You Will Learn - Use kernel facilities to develop powerful drivers - Develop drivers for widely used I2C and SPI devices and use the regmap API - Write and support devicetree from within your drivers - Program advanced drivers for network and frame buffer devices - Delve into the Linux irqdomain API and write interrupt controller drivers - Enhance your skills with regulator and PWM frameworks - Develop measurement system drivers with IIO framework - Get the best from memory management and the DMA subsystem - Access and manage GPIO subsystems and develop GPIO controller drivers In Detail Linux kernel is a complex, portable, modular and widely used piece of software, running on around 80% of servers and embedded systems in more than half of devices throughout the World. Device drivers play a critical role in how well a Linux system performs. As Linux has turned out to be one of the most popular operating systems used, the interest in developing proprietary device drivers is also increasing steadily. This book will initially help you understand the basics of drivers as well as prepare for the long journey through the Linux Kernel. This book then covers drivers development based on various Linux subsystems such as memory management, PWM, RTC, IIO, IRQ management, and so on. The book also offers a practical approach on direct memory access and network device drivers. By the end of this book, you will be comfortable with the concept of device driver development and will be in a position to write any device driver from scratch using the latest kernel version (v4.13 at the time of writing this book). Style and approach A set of engaging examples to develop Linux device drivers
Master the art of developing customized device drivers for your embedded Linux systems
Key Features:
Stay up to date with the Linux PCI, ASoC, and V4L2 subsystems and write device drivers for them
Get to grips with the Linux kernel power management infrastructure
Adopt a practical approach to customizing your Linux environment using best practices
Book Description:
Linux 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 system programmers who want to explore Linux kernel frameworks and subsystems. C programming skills and a basic understanding of driver development are necessary to get started with this book.
