Honestly, that's the first time I hear about it, and as I'm not allowed to look at qemu code (legal reasons, just don't ask ;-) it's hard for me to comment. But during the discussions about virtio-mmio, no one mentioned it at all! Is it similar in ideas? I do apologise if I jeopardised somebody's work, but it wasn't on purpose... Cheers! Paweł
