Re: How to implement virtual hardware in QEMU?

Hello everyone,

I want to implement some virtual hardware in QEMU for driver testing. For example, to implement a timer which sends interrupt to CPU periodically. 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.

So, are there helpful videos or articles?

I wrote something like this a few years ago: https://github.com/levex/kernel-qemu-pci Not sure if it still works, but it may be enough to get you started. Hope this helps. Levente
