In this case, you can look at anything which calls um_request_irq, and
see what you need to do in order to set up the call - set up the file
descriptor that will be causing the interrupts, write the interrupt

What driver you look at depends on the type of hardware you want to simulate.

This I don't know about. Presumably, the ioports driver has some sort
of interface which lets other drivers register ports with it.
