Clemens already answered your questions. There are also plenty of
drivers in the mainline kernel that can serve as an example. Unless
you get more specific about what you're planning to do, I doubt that
anyone can give you more specific help. What hardware is your driver
for, or is it purley virtual? What's the end application?
