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.
这书几乎对Linux内核中的主要子系统的源码进行了逐行分析,确实需要我们静下来沉下心来,花一段不短的时间来阅读源码。 虽然我们自己去写一个操作系统的可能性很小,但是如果能深入理解这么庞大的系统,能阅读几万甚至几十万行优秀的代码,还有什么系统的源代码是我们不能理解...
評分 評分这本书是好书,我就不重复那些赞美之词了。 但提醒一下,新买这本书的战友们要注意了,从2.6.23版本的内核开始,进程调度方式就不再是书中提到的O(1)调度方式,而是改成了完全公平调度(CFS),大家可以看看Robert Love的《Linux内核设计与实现》第三版。还可以参考下面地址...

評分如果你是一个 C 程序员,你想过这些问题吗:空指针到底是什么?你调用 malloc 时,系统做了什么?fork 是怎么实现的?如果你很好奇,如果你是一位有志青年,你可以看看这本书。 操作系统是什么?操作系统其实是运行在硬件上的一个程序,这个程序的客户是应用软件,如:office...
英文版通俗易懂,可以作為學習操作係統或者內核相關開發的參考
评分書沒什麼意思,太雜太散瞭。
评分11年的時候, 因為這本書內容太老, 就選擇看瞭德國人那本Professional Linux kernel architecture; 現在17年, 有機會讀這本書, 發現走錯路, 當年應該看這本.
评分書沒什麼意思,太雜太散瞭。
评分翻瞭翻,現在感覺這些都厚書 都差不多 總體把握吧
