SERIES
Tested-by: Eric Auger
with QEMU branch:
https://github.com/eauger/qemu/tree/v4.0-virtio-iommu-v0.12
and kernel branch:
https://github.com/eauger/linux/tree/virtio-iommu-v0.12
(where I just added the rebased iort patches on top of Jean-Philippe's
virtio-iommu/v0.12 branch). So I also tested the ACPI boot.
I will formally submit the QEMU series ASAP.
Thanks
Eric
