Thank you very much for your testing efforts. For your info, there are
more recent kernel series:
[PATCH v14 00/13] SMMUv3 Nested Stage Setup (IOMMU part) (Feb 23)
[PATCH v12 00/13] SMMUv3 Nested Stage Setup (VFIO part) (Feb 23)

working along with QEMU RFC
[RFC v8 00/28] vSMMUv3/pSMMUv3 2 stage VFIO integration (Feb 25)

If you have cycles to test with those, this would be higly appreciated.

Thanks
