Lu Baolu a5212518b7 iommu/vt-d: Use user privilege for RID2PASID translation ... [ Upstream commit 54c80d907400189b09548039be8f3b6e297e8ae3 ] When first-level page tables are used for IOVA translation, we use user privilege by setting U/S bit in the page table entry. This is to make it consistent with the second level translation, where the U/S enforcement is not available. Clear the SRE (Supervisor Request Enable) field in the pasid table entry of RID2PASID so that requests requesting the supervisor privilege are blocked and treated as DMA remapping faults.
