Table of Contents | Index

In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of

systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the

CPU and the external world, and determines which programs will share processor time, in what order. It

manages limited memory so well that hundreds of processes can share the system efficiently, and expertly

organizes data transfers so that the CPU isn't kept waiting any longer than necessary for the relatively slow

disks.

The third edition of Understanding the Linux Kernel takes you on a guided tour of the most significant data

structures, algorithms, and programming tricks used in the kernel. Probing beyond superficial features, the

authors offer valuable insights to people who want to know how things really work inside their machine.

Important Intel-specific features are discussed. Relevant segments of code are dissected line by line. But the

book covers more than just the functioning of the code; it explains the theoretical underpinnings of why

Linux does things the way it does.

This edition of the book covers Version 2.6, which has seen significant changes to nearly every kernel

subsystem, particularly in the areas of memory management and block devices. The book focuses on the

following topics:

Memory management, including file buffering, process swapping, and Direct memory Access

(DMA)

•

The Virtual Filesystem layer and the Second and Third Extended Filesystems•

Process creation and scheduling•

Signals, interrupts, and the essential interfaces to device drivers•

Timing•

Synchronization within the kernel•

Interprocess Communication (IPC)•

Program execution•

Understanding the Linux Kernel will acquaint you with all the inner workings of Linux, but it's more than

just an academic exercise. You'll learn what conditions bring out Linux's best performance, and you'll see

how it meets the challenge of providing good system response during process scheduling, file access, and

memory management in a wide variety of environments. This book will help you make the most of your

Linux system.
