Disallowing shared IRQs means disallowing PCI devices in general, so now you are back to ISA only devices, which it sounds like were the only things already allowed by vm86 or whatever it was for passing through. MSI would be good, but how long until all devices support that? Certainly does appear to have potential though for allowing more interesting virtual machines. -- Len Sorensen - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
