Most machiens I see today have almost no chance of having PCI devices without shared IRQs. This probably means any implementation will only work on a small set of machines with very specific setup in terms of which PCI slots they install cards in, and only as long as you don't allow any type of hotplugging of devices (or ever changing hardware at all). May not be worth implementing if it has such a limited use case. The MSI setup on the other hand does sound like it might have potential for working in general. > IMO pass-through is counter to most of the benefits of virtualization. > But users seem to want it. Certainly if you can have the host manage the device and provide virutal access instead, that is much better. -- Len Sorensen - 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/
