[PATCH v16 00/10] VIRTIO-IOMMU device |

This series implements the QEMU virtio-iommu device.
This matches the v0.12 spec (voted) and the corresponding
virtio-iommu driver upstreamed in 5.3. All kernel dependencies
are resolved for DT integration. The virtio-iommu can be
instantiated in ARM virt using:
"-device virtio-iommu-pci".
Non DT mode is not yet supported as it has non resolved kernel
dependencies [1].
This feature targets 5.0.
Integration with vhost devices and vfio devices is not part
of this series. Please follow Bharat's respins [2].
Best Regards
Eric

References:
[1] [RFC 00/13] virtio-iommu on non-devicetree platforms
[2] [PATCH RFC v5 0/5] virtio-iommu: VFIO integration
Testing:
- tested with guest using virtio-net-pci
(,vhost=off,iommu_platform,disable-modern=off,disable-legacy=on)
and virtio-blk-pci
- migration
History:
v15 -> v16:
- Collected Jean, Peter and Michael's R-bs
- last patches without R-b is the one related to hw/arm/virt.c
+ the last patch, added in this version
- Made the virtio-iommu-pci not hotpluggable (I dared to
leave the R-b though)
- Renamed create_virtio_iommu into create_virtio_iommu_dt_bindings
- added entry in maintenance file
v14 -> v15:
- removed x-dt-binding and just kept check on hotplug_handler
- removed "tests: Add virtio-iommu test" as the check on
hotplug_handler fails on PC machine
- destroy mappings in put_domain and remove
g_tree_destroy(domain->mappings) in virtio_iommu_detach
v13 -> v14:
- added "virtio-iommu-pci: Introduce the x-dt-binding option"
- Removed the mappings gtree ref counting and simply delete
the gtree when the last EP is detached from the domain
