Index of Further Kernel Documentation

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.

PLEASE, if you know any paper not listed here or write a new document, include a reference to it here, following the kernel’s patch submission process. Any corrections, ideas or comments are also welcome.

All documents 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.

Note

The documents on each section of this document are ordered by its published date, from the newest to the oldest. The maintainer(s) should periodically retire resources as they become obsolte or outdated; with the exception of foundational books.
