The Ext2 and Ext3 Filesystems. Process Communication. Program Execution.

System Startup. The idea was to encourage students to read the source code. To achieve this, we assigned term projects consisting of making changes to the kernel and performing tests on the modified version.

Linux Kernel Development, 3rd Edition

We also wrote course notes for our students about a few critical features of Linux such as task switching and task scheduling. The success encountered by this book encouraged us to continue along this line.

At the end of , we came out with a second edition covering Linux 2. You are now looking at the third edition, which covers Linux 2.

As in our previous experiences, we read thousands of lines of code, trying to make sense of them. After all this work, we can say that it was worth the effort. The Audience for This Book All people curious about how Linux works and why it is so efficient will find answers here. After reading the book, you will find your way through the many thousands of lines of code, distinguishing between crucial data structures and secondary ones—in short, becoming a true Linux hacker.

Our work might be considered a guided tour of the Linux kernel: most of the significant data structures and many algorithms and programming tricks used in the kernel are discussed. In many cases, the relevant fragments of code are discussed line by line. Of course, you should have the Linux source code on hand and should be willing to expend some effort deciphering some of the functions that are not, for sake of brevity, fully described.

On another level, the book provides valuable insight to people who want to know more about the critical design issues in a modern operating system.

It is not specifically addressed to system administrators or programmers; it is mostly for people who want to understand how things really work inside the machine!

As with any good guide, we try to go beyond superficial features. We offer a background, such as the history of major features and the reasons why they were used.

Organization of the Material When we began to write this book, we were faced with a critical decision: should we refer to a specific hardware platform or skip the hardware-dependent details and concentrate on the pure hardware-independent parts of the kernel? If we want to convince you that the kernel indeed does quite a good job in performing a specific task, we must first tell what kind of support comes from the hardware.

A thorough knowledge of the kernel, therefore, requires the study of a few assembly language fragments that interact with the hardware. When covering hardware features, our strategy is quite simple: only sketch the features that are totally hardware-driven while detailing those that need some software support.

In fact, we are interested in kernel design rather than in computer architecture.

Our next step in choosing our path consisted of selecting the computer system to describe. In a few cases, explicit references will be made to specific models. In September , Morton decided to stop maintaining this tree. BitKeeper was made available to Torvald and several others free of charge but was not free software , which was a source of controversy. In response, Torvalds and others wrote a new source code control system for the purpose, called Git.

The new system was written within weeks, and in two months the first official kernel release was made using Git. Kernel 3.

Volunteer developers contributed 16 percent of the total changes to the kernel in The other changes were contributions by professional software developers who were paid by a company to submit code to the kernel. In Red Hat developers contributed 10 percent of the changes made to the kernel, the second largest corporate contributor being Intel , followed by IBM and Novell. While Nokia had by that time abandoned its Linux kernel based smartphone operating system MeeGo , in Nokia developers still contributed more code to the kernel than the developers employed by Google , which had released Android in and Chrome OS in By Microsoft ranged as the 17th most prolific corporate contributor to the kernel.

Its developers had first started contributing to the kernel in to improving the performance of Linux virtual machines running on top of the Windows Hyper-V hypervisor. To account for the occasional special patch release, the version 3 series of the kernel added a fourth digit to the version numbering.

In April , Torvalds released kernel version 4. Please update this article to reflect recent events or newly available information.

July Main article: Usage share of operating systems Linux distributions that bundle the Linux kernel with applications , Unix programs and application packages are responsible for the rising popularity of Linux operating systems among users.

Many desktop Linux distributions including the Linux kernel exist, but the usage share of Linux distributions is low in comparison to other operating systems. It covers the Linux kernel with both a practical and theoretical eye, which should appeal to readers with a variety of interests and needs. The author, a core kernel developer, shares valuable knowledge and experience on the 2.

Specific topics covered include process management, scheduling, time management and timers, the system call interface, memory addressing, memory management, the page cache, the VFS, kernel synchronization, portability concerns, and debugging techniques.

This book covers the most interesting features of the Linux 2.

The third edition of Linux Kernel Development includes new and updated material throughout the book: An all-new chapter on kernel data structures. Details on interrupt handlers and bottom halves.

Extended coverage of virtual memory and memory allocation. Tips on debugging the Linux kernel.Then we usually move from the lowest level of functions to higher levels, often ending by showing how system calls issued by user applications are supported.

Each chapter starts with a theoretical overview of the topics covered.

Chapter 7, Process Scheduling, explains how Linux executes, in turn, every active process in the system so that all of them can progress toward their completions.

This book covers the most interesting features of the Linux 2. When Torvalds released version 0. The other changes were contributions by professional software developers who were paid by a company to submit code to the kernel. We start with the data structures needed to support the functionalities described in the chapter.
