[PATCH v5 15/18] hw/arm/smmuv3: Support nested SMMUs in smmuv3_notify_iova()

2024-07-15 Thread Mostafa Saleh
IOMMUTLBEvent only understands IOVA, for stage-1 or stage-2 SMMU instances we consider the input address as the IOVA, but when nesting is used, we can't mix stage-1 and stage-2 addresses, so for nesting only stage-1 is considered the IOVA and would be notified. Signed-off-by: Mostafa Saleh --- h
