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.
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:...
評分首先,我要强烈建议的是:这本书一定要看英文版的(买不到的话可以网上下pdf,然后淘宝上打印)! 其次,我还要提醒一下linxu kernel的初学者:读这本书之前,要看一些讲解操作系统原理和概念的书。 最后,对于初次看这本书的读者来说:不要指望读一遍就把这本书都搞懂。因为...
評分对以 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。
評分译者相当不负责任, 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...
評分很多句子都不变换一下语序,不知道是偷懒还是连最基本的翻译技巧都不知道。最过分的是常用的说法翻的也不够地道,最典型的是“上下文”被翻成了“文境”,但搞笑的是在附录的索引里却翻成了“上下文”。还有很多术语也不符合常规的说法,看的很不爽!
內核驅動必讀書目
评分內容比較全麵,但組織上有點分散,比如進程、進程調度、進程通信等分散在三個角落裏。原理和具體實現相結閤,閱讀Linux內核源代碼時可以一邊讀一下做參考
评分主要講的還是宏觀的結構,該書必須結閤源代碼一起看纔有足夠的收獲
评分英文版通俗易懂,可以作為學習操作係統或者內核相關開發的參考
评分不知道該讀多少遍
