I absolutely disagree with you Eric, and I think you're being rediculious. If the hypervisor doesn't control the MSI PCI config space register writes, this allows the device to spam PCI devices which belong to other domains. It's a freakin' reasonable design trade off decision, get over it! :-) Yes it can be done at the hardware level, and many hypervisor based systems do that, but it's not the one-and-only true way to implment inter-domain protection behind a single PCI host controller. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
