Hi, Avi

This patchset enable MSI support for KVM VT-d.

And here are only kernel space ones. The third patch would go to also goto x86
upstream.

The userspace code would looks like this:

assigned_irq_data.guest_msi_addr = *(uint32_t *)(d->msi_cap + 4);
assigned_irq_data.guest_msi_data = *(uint16_t *)(d->msi_cap + 8);
assigned_irq_data.flags |= KVM_DEV_IRQ_ASSIGN_ENABLE_MSI;
r = kvm_assign_irq(kvm_context, &assigned_irq_data);

I've test the patchset with some userspace hack, it works well.

Thanks!
