Understanding the Linux Kernel, 2nd Edition
Publisher: O'Reilly Media
Released: December 2002
Pages: 784

To thoroughly understand what makes Linux tick and why it's so efficient, you need to delve deep into the heart of the operating system--into the Linux kernel itself. The kernel is Linux--in the case of the Linux operating system, it's the only bit of software to which the term "Linux" applies. The kernel handles all the requests or completed I/O operations and determines which programs will share its processing time, and in what order. Responsible for the sophisticated memory management of the whole system, the Linux kernel is the force behind the legendary Linux efficiency.

The new edition of Understanding the Linux Kernel takes you on a guided tour through the most significant data structures, many algorithms, and programming tricks used in the kernel. Probing beyond the superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Relevant segments of code are dissected and discussed line by line. The book covers more than just the functioning of the code, it explains the theoretical underpinnings for why Linux does things the way it does.

The new edition of the book has been updated to cover version 2.4 of the kernel, which is quite different from version 2.2: the virtual memory system is entirely new, support for multiprocessor systems is improved, and whole new classes of hardware devices have been added. The authors explore each new feature in detail. Other topics in the book include:

  • Memory management including file buffering, process swapping, and Direct memory Access (DMA)
  • The Virtual Filesystem and the Second Extended Filesystem
  • Process creation and scheduling
  • Signals, interrupts, and the essential interfaces to device drivers
  • Timing
  • Synchronization in the kernel
  • Interprocess Communication (IPC)
  • Program execution
Understanding the Linux Kernel, Second Edition will acquaint you with all the inner workings of Linux, but is 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. If knowledge is power, then this book will help you make the most of your Linux system.

Understanding the Linux Kernel, 2nd Edition Review

By mohit singh

from Undisclosed

Comments about O'Reilly Media Understanding the Linux Kernel, 2nd Edition:

this book details the linux kernel design better than 'linux kernel internals' by michael beck et.al., but the code commentary could be better complement.

i think i must wait for third edition.

I highly recommend this book. It does a very good job at explaining both the overall kernel architecture, and the intel target implementation specifics.

A must have!

Understanding the Linux Kernel, 2nd Edition Review

By Schmel

from Undisclosed

Comments about O'Reilly Media Understanding the Linux Kernel, 2nd Edition:

Wow. Quite a few errata -- some rather significant -- for an edition which not many people own yet. Does anyone know how big the first printing was? Maybe I'll hold off for the second printing.
