Essential Linux Device Drivers下载

Chapter 1, "Introduction," starts our tryst with Linux. It hurries you through downloading the kernel sources, making trivial code changes, and building a bootable kernel image. Chapter 2, "A Peek Inside the Kernel," takes a brisk peek into the innards of the Linux kernel and teaches you some must-know kernel concepts. It first takes you through the boot process and then describes kernel services particularly relevant to driver development such as kernel threads, timers, concurrency, and memory management. Chapter 3, "Getting Started with Device Drivers," gets you started with the art of writing Linux device drivers. It looks at interrupt handling, the new Linux device model, and Linux assembly. In this chapter, you'll also learn to use kernel helper interfaces such as linked lists, work queues, completion functions, and notifier chains. These helper facilities simplify your code, weed out redundancies from the kernel, and help long-term maintenance. Chapter 4, "Character Drivers," looks at the architecture of character device drivers. Several concepts introduced in this chapter such as polling, asynchronous notification, and I/O control, are relevant to subsequent chapters as well, since many device classes discussed in the rest of the book are 'super' character devices. Chapter 5, "Serial Drivers," explains the kernel layer that handles serial devices. The serial layer consists of low-level drivers, the TTY layer, and line disciplines. Chapter 6, "Input Drivers," discusses the kernel's input subsystem that is responsible for servicing devices such as keyboards, mice, and touch panels. Chapter 7, "The Inter-Integrated Circuit Protocol," dissects drivers for devices such as EEPROMs that are connected to the system I2C bus or SMBus. The chapter also looks at other serial technologies such as the SPI bus and one-wire bus. Chapter 8,"PCMCIA and Compact Flash," delves into the PCMCIA subsystem. It teaches you to write drivers for devices having a PCMCIA or Compact Flash form factor. Chapter 9, "Peripheral Component Interconnect," looks at kernel support for PCI and its derivatives such as CardBus and PCI Express. Chapter 10, "Universal Serial Bus," explores USB architecture and device drivers. Chapter 11, "Video Drivers," explains the Linux video family. Chapter 12, "Audio Drivers," describes the Linux audio family. Chapter 13, "Block Drivers," covers drivers for devices such as IDE and SCSI. It also looks at filesystem drivers. Chapter 14, "Network Interface Cards," is dedicated to network devices. You'll learn about kernel networking data structures and how to interface network drivers with protocol layers. Chapter 15, "Linux Without Wires," looks at driving different wireless technologies such as Bluetooth, Infrared, WiFi and cellular communication. Chapter 16, "Memory Technology Devices," discusses flash memory enablement. This chapter first looks at flash-based protocols and chipsets primarily used on embedded devices. It ends by examining drivers for the Firmware Hub found on desktops and laptops. Chapter 17, "Embedding Linux," steps into the world of embedded Linux. It takes you through the main firmware components of an embedded solution, such as bootloader, kernel, and device drivers. Given the soaring popularity of Linux in the embedded space, it's likely that you'll use the device driver skills that you acquire from this book, to enable embedded devices. Chapter 18, "User Mode Drivers," looks at driving different types of devices from user space. Some device drivers, especially ones that are heavy on policy and light on performance requirements, are better off residing in user land. This chapter also explains how the new ultra-scalable process scheduler improves response times of user mode drivers. Chapter 19, "More Devices and Drivers," takes a tour of a potpourri of driver families not covered thus far, such as Error Detection And Correction (EDAC), cpufreq<...
