I expect we'll get a QEMU implementation too at some point, but we should be able to just make that match whatever you decide is the correct layout and behaviour. The only constraint QEMU has which kvmtool doesn't is that we care about not randomly shuffling things around between QEMU versions, so whatever we pick we're more or less stuck with. So a layout which leaves scope for "supports PCI now, may do PCI-e later, MSI after that" would be good. (My PCI knowledge is very piecemeal, I hope that makes sense...) thanks -- PMM -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
