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.
