This is not what's going on.
The hypervisor does the PCI config space programming on the device to setup the MSI so that it can be done in a controlled manner and such that the device cannot ever be configured by one domain to shoot MSI packets over at devices which belong to another domain.
It's that simple.
That's absolutely reasonable, and is I believe what you'll see the sparc64 hypervisor(s) all needing as well. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
