Subject: RE: [PATCH v12 00/13] SMMUv3 Nested Stage Setup (VFIO part)

Tested-by: Krishna Reddy <vdumpa@...dia.com>

Validated Nested SMMUv3 translations for NVMe PCIe device from Guest VM and is functional.

This patch series resolved the mismatch(seen with v11 patches) for VFIO_IOMMU_SET_PASID_TABLE and VFIO_IOMMU_CACHE_INVALIDATE Ioctls between linux and QEMU patch series "vSMMUv3/pSMMUv3 2 stage VFIO integration" (v5.2.0-2stage-rfcv8).
