Develop Linux device drivers from scratch, with hands-on guidance focused on embedded systems, covering key subsystems like I2C, SPI, GPIO, IRQ, and DMA for real-world hardware integration using kernel 4.13Key FeaturesDevelop custom drivers for I2C, SPI, GPIO, RTC, and input devices using modern Linux kernel APIsLearn memory management, IRQ handling, DMA, and the device tree through hands on examplesExplore embedded driver development with platform drivers, regmap, and IIO frameworksBook DescriptionLinux 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).What you will learnUse kernel facilities to develop powerful driversDevelop drivers for widely used I2C and SPI devices and use the regmap APIWrite and support devicetree from within your driversProgram advanced drivers for network and frame buffer devicesDelve into the Linux irqdomain API and write interrupt controller driversEnhance your skills with regulator and PWM frameworksDevelop measurement system drivers with IIO frameworkGet the best from memory management and the DMA subsystemAccess and manage GPIO subsystems and develop GPIO controller driversWho this book is forThis book is ideal for embedded systems developers, engineers, and Linux enthusiasts who want to learn how to write device drivers from scratch. Whether you're new to kernel development or looking to deepen your understanding of subsystems like I2C, SPI, and IRQs, this book provides practical, real-world instructions tailored for working with embedded Linux platforms. Foundational knowledge of C and basic Linux concepts is recommended.

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 FeaturesGain hands-on expertise with real Linux subsystems: PCI, ALSA SoC, V4L2, and power managementApply advanced techniques for kernel debugging, regmap API, and custom hardware integrationBuild robust drivers through step-by-step examples and practical engineering insightsBook 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 learnExplore and adopt Linux kernel helpers for locking, work deferral, and interrupt managementUnderstand the Regmap subsystem to manage memory accesses and work with the IRQ subsystemGet to grips with the PCI subsystem and write reliable drivers for PCI devicesWrite full multimedia device drivers using ALSA SoC and the V4L2 frameworkBuild power-aware device drivers using the kernel power management frameworkFind out how to get the most out of miscellaneous kernel subsystems such as NVMEM and WatchdogWho this book is forThis 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.

Get up to speed with the most important concepts in driver development and focus on common embedded system requirements such as memory management, interrupt management, and locking mechanismsKey FeaturesWrite feature-rich and customized Linux device drivers for any character, SPI, and I2C deviceDevelop a deep understanding of locking primitives, IRQ management, memory management, DMA, and so onGain practical experience in the embedded side of Linux using GPIO, IIO, and input subsystemsBook DescriptionLinux is by far the most-used kernel on embedded systems. Thanks to its subsystems, the Linux kernel supports almost all of the application fields in the industrial world. This updated second edition of Linux Device Driver Development is a comprehensive introduction to the Linux kernel world and the different subsystems that it is made of, and will be useful for embedded developers from any discipline.You'll learn how to configure, tailor, and build the Linux kernel. Filled with real-world examples, the book covers each of the most-used subsystems in the embedded domains such as GPIO, direct memory access, interrupt management, and I2C/SPI device drivers. This book will show you how Linux abstracts each device from a hardware point of view and how a device is bound to its driver(s). You'll also see how interrupts are propagated in the system as the book covers the interrupt processing mechanisms in-depth and describes every kernel structure and API involved. This new edition also addresses how not to write device drivers using user space libraries for GPIO clients, I2C, and SPI drivers.By the end of this Linux book, you'll be able to write device drivers for most of the embedded devices out there. What you will learnDownload, configure, build, and tailor the Linux kernelDescribe the hardware using a device treeWrite feature-rich platform drivers and leverage I2C and SPI busesGet the most out of the new concurrency managed workqueue infrastructureUnderstand the Linux kernel timekeeping mechanism and use time-related APIsUse the regmap framework to factor the code and make it genericOffload CPU for memory copies using DMAInteract with the real world using GPIO, IIO, and input subsystemsWho this book is forThis Linux OS book is for embedded system and embedded Linux enthusiasts/developers who want to get started with Linux kernel development and leverage its subsystems. Electronic hackers and hobbyists interested in Linux kernel development as well as anyone looking to interact with the platform using GPIO, IIO, and input subsystems will also find this book useful.
