One other thing to be aware of is that vfio requires devices to be PCI-2.3 compliant in order to support DisINTx. This allows vfio to support devices making use of shared INTx interrupts, but excludes older devices that users maybe managed to get assigned to an exclusive interrupt for kvm style assignment. I suppose we might be able to make vfio work with either pci 2.3 devices or older devices with exclusive interrupts if that ends up affecting many users.
PCI 2.3 is already old enough (6-7 years?) that I believe we can require it. -- I have a truly marvellous patch that fixes the bug which this signature is too narrow to contain. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
