  8The need for a document like this one became apparent in the
  9linux-kernel mailing list as the same questions, asking for pointers
 10to information, appeared again and again.
 11
 12Fortunately, as more and more people get to GNU/Linux, more and more
 13get interested in the Kernel. But reading the sources is not always
 14enough. It is easy to understand the code, but miss the concepts, the
 15philosophy and design decisions behind this code.
 16
 17Unfortunately, not many documents are available for beginners to
 18start. And, even if they exist, there was no "well-known" place which
 19kept track of them. These lines try to cover this lack. All documents
 20available on line known by the author are listed, while some reference
 21books are also mentioned.
 22
 23PLEASE, if you know any paper not listed here or write a new document,
 24send me an e-mail, and I'll include a reference to it here. Any
 25corrections, ideas or comments are also welcomed.
 26
 27The papers that follow are listed in no particular order. All are
 28cataloged with the following fields: the document's "Title", the
 29"Author"/s, the "URL" where they can be found, some "Keywords" helpful
 30when searching for specific topics, and a brief "Description" of the
 31Document.
 32
 33Enjoy!

 78        as a tool to understand a running Linux system.
 79        Having obtained a trace-log a kernel hacker can read and understand

 81        In a detailed example this approach is demonstrated in tracing
 82        and the way of data in a TCP Connection through the kernel.
 83        Finally this trace-log is used as base for more a exact conceptual

251      :Description: From the Introduction: "I/O Event handling is about
252        how your Operating System allows you to manage a large number of
253        open files (file descriptors in UNIX/POSIX, or FDs) in your
254        application. You want the OS to notify you when FDs become active
255        (have data ready to be read or are ready for writing). Ideally you
256        want a mechanism that is scalable. This means a large number of
257        inactive FDs cost very little in memory and CPU time to manage".

385        Though it is conceptually simple, practical limitations and
386        constraints make this an ''interesting'' part of device driver
387        writing, and several different facilities have been provided for

  8The need for a document like this one became apparent in the
  9linux-kernel mailing list as the same questions, asking for pointers
 10to information, appeared again and again.
 11
 12Fortunately, as more and more people get to GNU/Linux, more and more
 13get interested in the Kernel. But reading the sources is not always
 14enough. It is easy to understand the code, but miss the concepts, the
 15philosophy and design decisions behind this code.
 16
 17Unfortunately, not many documents are available for beginners to
 18start. And, even if they exist, there was no "well-known" place which
 19kept track of them. These lines try to cover this lack. All documents
 20available on line known by the author are listed, while some reference
 21books are also mentioned.
 22
 23PLEASE, if you know any paper not listed here or write a new document,
 24send me an e-mail, and I'll include a reference to it here. Any
 25corrections, ideas or comments are also welcomed.

 27The papers that follow are listed in no particular order. All are
 28cataloged with the following fields: the document's "Title", the
 29"Author"/s, the "URL" where they can be found, some "Keywords" helpful
 30when searching for specific topics, and a brief "Description" of the
 31Document.

 60      :Keywords: HOWTO, kernel contexts, deadlock, locking, modules,
 61        symbols, return conventions.
 62      :Description: From the Introduction: "Please understand that I
 63        never wanted to write this document, being grossly underqualified,
 64        but I always wanted to read it, and this was the only way. I
 65        simply explain some best practices, and give reading entry-points
 66        into the kernel sources. I avoid implementation details: that's
 67        what the code is for, and I ignore whole tracts of useful
 68        routines. This document assumes familiarity with C, and an
 69        understanding of what the kernel is, and how it is used. It was
 70        originally written for the 2.3 kernels, but nearly all of it
 71        applies to 2.2 too; 2.0 is slightly different".

 77      :Keywords: locks, locking, spinlock, semaphore, atomic, race
 78        condition, bottom halves, tasklets, softirqs.
 79      :Description: The title says it all: document describing the
 80        locking system in the Linux Kernel either in uniprocessor or SMP
 81        systems.
 82      :Notes: "It was originally written for the later (>2.3.47) 2.3
 83        kernels, but most of it applies to 2.2 too; 2.0 is slightly
 84        different". Freely redistributable under the conditions of the GNU

107        understanding linux kernel internals,
108        illustrated at tracing the way of a TCP packet through the kernel.
109      :Abstract: *This short paper outlines the usage of ftrace a tracing framework
110        as a tool to understand a running Linux system.
111        Having obtained a trace-log a kernel hacker can read and understand
112        source code more determined and with context.
113        In a detailed example this approach is demonstrated in tracing
114        and the way of data in a TCP Connection through the kernel.
115        Finally this trace-log is used as base for more a exact conceptual
116        exploration and description of the Linux TCP/IP implementation.*

294        event queues.
295      :Description: From the Introduction: "I/O Event handling is about
296        how your Operating System allows you to manage a large number of
297        open files (file descriptors in UNIX/POSIX, or FDs) in your
298        application. You want the OS to notify you when FDs become active
299        (have data ready to be read or are ready for writing). Ideally you
300        want a mechanism that is scalable. This means a large number of
301        inactive FDs cost very little in memory and CPU time to manage".

428        month, we further investigate the field of interrupt handling.
429        Though it is conceptually simple, practical limitations and
430        constraints make this an ''interesting'' part of device driver
431        writing, and several different facilities have been provided for
