This is turning into a FAQ, but don't worry about it. The usual answer is
to take one of the existing drivers and work out what it does. There's also
a script for making shell drivers under /usr/share/examples/drivers. As for
things like "how does DMA work?", "what exactly is an interrupt and what do
I do with it?" or "what's the story with memory ranges and devices then?"
then I'm afraid I can't help you there.
In fact (to -hackers) this strikes me as one of the more fundamental
problems of free software: I would go and write/fix some device drivers
(for example the unknown phy in fxp that bothers me so much), except I
can't really get a handle on how you're supposed to start on these things.
Comments? URL's for IRQ101? Perhaps I should just stop whingeing and go
hack with it to see what happens? (probably best).
