The SMMU provides address translation for an I/O device to identify more than its actual addressing capability. In the absence of memory isolation, I/O devices can corrupt system memory. The SMMU provides device isolation to prevent DMA attacks. To offer isolation and memory protection, it restricts device access for DMA-capable I/O to a pre-assigned physical space.
