With the push of virtualization, the x86 world started recently to gain a more widespread attention towards supporting IOMMUs; similar to MMUs that translate virtual addresses into physical ones, an IOMMU translates device/bus addresses into physical addresses. The purpose of this project is to add AMD and Intel IOMMU support in NetBSD's machine-independent bus abstraction layers bus.space(9) and bus.dma(9).
