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.

读后感

译者相当不负责任, 感觉他就是把英文句子逐词地翻译过来, 都不带调整的, 读起来相当生硬且晦涩, 审校更加不负责, 这样的翻译都可以通过? 我的评论哪儿短了? 我的评论哪儿短了? 我的评论哪儿短了? 我的评论哪儿短了? 我的评论哪儿短了? 我的评论哪儿短了? 我的评论哪儿短了? 我...  

一、硬伤 P101L4 ~ L6的内容为: "没有为处于TASK_STOPPED、、EXIT_ZOMBIE或EXIT_DEAD状态的进程建立专 门的链表。由于对处于暂停、僵死、死亡状态进程的访问比较简单，或者通过PID， 或者通过特定父进程的子进程链表，所以不必对这三种状态进程分组。" L7 ~ L9的内容为：...  

这本书的英文名是Understanding the linux kernel,怎么翻译成中文就是“深入理解linux内核”，“深入”在哪里，这么喜欢添油加醋，翻译别人的东西就不要自由发挥了，把意思翻译出来就行了，不必要添加这些无关紧要的东西  

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...  

时不时就会冒出这种感觉。错误真的很多，感觉有时候是译者根本没有理解才会发生这种错误。比如812页这句，the traced program can be executed step-by-step, until a signal is received, or until a system call is invoked.被翻译做“被跟踪的程序一步一步地执行，直到接受...  

用户评价

书没什么意思，太杂太散了。

通透！

果然现在耐不下性子了么 该打

内容比较全面，但组织上有点分散，比如进程、进程调度、进程通信等分散在三个角落里。原理和具体实现相结合，阅读Linux内核源代码时可以一边读一下做参考
