As you'll see below, the hardware intreface is somewhat ad-hoc :-)IMO it fits perfectly into a qdev which contains 8 qbuses, each of which is connected to another qdev.
Do you mean a qdev that is a bus and accepts up to 8 devices as children? Regards, Anthony Liguori
The plan would be: - fold sysbus into qdev - improve qdev/qbus memory region support - reimplement PCI BARs atop qdev regions
