A driver

I've always been fascinated by the Linux kernel, mainly how so many drivers and bits get written into it with so little 'real' documentation. Some of it's there, scattered across the web. I've yet to find anything as comforting as a Linux kernel doxygen manual.

The closest thing that's currently up and running is LXR (http://lxr.linux.no) - a sourcecode viewer/search site.

I've been holding off from actual kernel hacking for a long time (this is mainly down to intimidation), but yesterday I finally bit the bullet and started reading source code properly and trying to understand it. And turns out, it's not so bad after all. To prove it, I wrote a simple proc file driver: http://fluffy.bizarrefish.org.uk/sync/fun/lee.c

Toodleoo. I'll have something big to write about soon, I imagine.
