Index of Documentation for People Interested in Writing and/or Understanding the Linux Kernel. Juan-Mariano de Goyeneche <jmseyas@dit.upm.es> /* * The latest version of this document may be found at: * http://www.dit.upm.es/~jmseyas/linux/kernel/hackers-docs.html */ The need for a document like this one became apparent in the linux-kernel mailing list as the same questions, asking for pointers to information, appeared again and again. Fortunately, as more and more people get to GNU/Linux, more and more get interested in the Kernel. But reading the sources is not always enough. It is easy to understand the code, but miss the concepts, the philosophy and design decisions behind this code. Unfortunately, not many documents are available for beginners to start. And, even if they exist, there was no "well-known" place which kept track of them. These lines try to cover this lack. All documents available on line known by the author are listed, while some reference books are also mentioned. PLEASE, if you know any paper not listed here or write a new document, send me an e-mail, and I'll include a reference to it here. Any corrections, ideas or comments are also welcomed. The papers that follow are listed in no particular order. All are cataloged with the following fields: the document's "Title", the "Author"/s, the "URL" where they can be found, some "Keywords" helpful when searching for specific topics, and a brief "Description" of the Document. Enjoy!
