Hello, I see many people in the list asking where do I start? In my opinion the best way to learn kernel development is first learning some basic concepts and start coding to get your hands dirty. The Linux Device Drivers 3 book is a good start. Both the book and source code examples are freely available. The problem is that the book is a few years old and the example drivers do not compile in recent kernels. I started a project to keep the LDD3 examples up-to-date with recent kernels. The git tree can be cloned from git://github.com/martinezjavier/ldd3.git I will try to keep the code always in sync with linux-next but there will be tags to stable versions. Now there are tags that compile with kernel versions 2.6.32, 2.6.35 and 2.6.37. I didn't try all the drivers with the three kernel versions, just compile tested. So any bug, comment or patch is always welcome -- Best regards, ----------------------------------------- Javier MartÃnez Canillas (+34) 682 39 81 69
