I sent a separate patch to add these devices to the regular broken INTx quirk in pci-core: http://www.spinics.net/lists/linux-pci/msg61971.html We don't currently have a device flag to specify that INTx is broken in this particular way that vfio can work around, nor do I really know how other drivers might make use of this info. If I'm wrong, then certainly let's make a common way to do this, but this patch is just a trivial extension to an existing mechanism. Thanks, Alex
