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.

对以 所有学计算机的人,OS是一个永远都绕不过去的话题,一个主修CS的人,如果不懂操作系统,是绝对应该被鄙视的。 但是可惜的是 中国现有的CS培养模式,让绝大部分学生没有机会动手自己写一个kernel。

我只读过中文版,没有读过英文版,主要谈一下中文版的阅读感受。有些人说该书有很多翻译错误,我在阅读过程中也发现了一些低级小错误,但总的来说读书的过程还算比较流畅的。 该书内容丰富,对Linux内核的各部分都讲解到了,主要有内存管理、进程管理、中断异常、文件系统以及...

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...

因为要做内核相关的东西了,理所当然的买了这本书,刚读了开头就觉得:一本好书让翻译给毁掉了。并不是说技术上不行,而是这些个翻译的态度就不端正!比如刚开始第一页,把SVR写成了SRV,下面的注释中竟然把linus torvalds的名字写错了。虽然不是什么大问题,也不会影响到读者...

不知道该读多少遍

#linux kernel source code 概览 未读完

总体感觉还行,细节较多,刚撸完一遍影印版,花了差不多一个月时间,建议和LDD一起看。 要深入内核,感觉还是要从代码入手,多调试下内核。 这本书撸完,就可以看毛德操的情景分析了。

终于扫完,还需要再扫几遍且多看代码#感谢公司搬家到每天上下班3时的地方让我看书

书没什么意思,太杂太散了。
