It looks to me that this description doesn't match the IOMMU part. [v14,05/13] iommu/smmuv3: Implement attach/detach_pasid_table | case IOMMU_PASID_CONFIG_TRANSLATE: | /* we do not support S1 <-> S1 transitions */ | if (smmu_domain->s1_cfg.set) | goto out; Maybe I've misread something? Thanks, Zenghui
