The concrete next steps here are well known. 1) Make MemoryRegion's QOM objects and add them as children to the devices that own them. 2) Make qemu_irq a QOM object. Then you could use -device to plumb up all of these things without SysBus being involved. But the above is a lot of work for a use-case that while interesting academically so far hasn't proven to be all that important. Regards, Anthony Liguori > > -- PMM
