Linux Device Drivers, 3rd Edition

This books must be the top priority for ever developer who wants to develop emebedded systems, based on Linux OS.

As a newbie it makes driver writing not so scary.
Technical masterpiece yet not over my head.

Used this to write my first linux driver on my own with no help. Great book, great layout, very well written. I have not read all of the 3rd Edition, since I am now working on Solaris, and did not work on the 2.6 kernel, but would assume thats good as well.

Un must per chi si avvicina alla programmazione di moduli del kernel, per chi e' esperto ma ha bisogno di un reference e per chi ne vuole sapere di piu'.

Il libro ha un'alta valenza didattica ed e' scritto in un linguaggio comprensibile e corretto. Gli esempi sono abbondanti e coprono bene gli argomenti trattati.

This book takes a hypothetical device driver and explains the concepts nicely. It provides various fundamentals one needs to know before writing linux device drivers, and valuable information like concurrent and race conditions, and gives ideas for debugging problems in real drivers. It is worth read and I liked it. I had already some experience in kernel programming before reading this book, and it filled holes in my kernel knowledge. This book is also available online[...] and you may check yourself before buying this.

The objections made by other reviewers fall into the following two classes. Once you are a experienced hacker, all you need is kernel sources (books are for fundamentals only and become obsolete as new kernel constructs are added). If you are looking for cut and paste template code to add new driver for another device, again use kernel source of an existing driver.
