However, I can't find any documentation which details the interfaces and the framework. The only clue is the `hw` directory in the source tree of QEMU, but it is so complex for a beginners to start up.

I wrote something like this a few years ago:

Not sure if it still works, but it may be enough to get you started.

Hope this helps.
