"The disadvantages of having an IOMMU, compared to direct physical addressing of the memory, include: • Some degradation of performance from translation and management overhead (e.g., page table walks). • Consumption of physical memory for the added I/O page (translation) tables. This can be mitigated if the tables can be shared with the processor. " - Iommu performance
