The iommu layer should maintain above attaching status per device and per iommu domain. There is no mdev/subdev concept in the iommu layer. It's just about RID or PASID.
Yes, I think that makes sense.
And a new set of IOMMU-API:
- iommu_{un}bind_pgtable(domain, dev, addr);
- iommu_{un}bind_pgtable_pasid(domain, dev, addr, pasid);
- iommu_cache_invalidate(domain, dev, invalid_info);What caches is this supposed to "invalidate"? _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
