But it isn't.
That's why I mentioned that this hack should become architecturally
specified (since it can work on real hardware too) with QEMU doing the
emulation for current-generation devices.

Well that dependency between devices is common for embedded hardware,
and this is what we have here.
Sure, but then you should put MCH/PCH/IGD in the same IOMMU group, which
basically means forgetting about IGD assignment.
