I thought that was sort of the definition of mediated - there needs to ben entify that "mediates" access so that a user of this interface can't trigger undmediated DMA to arbitrary addresses. My other choice that I used for a while was "virtual". sw_iommu sounds a little clumsy. I guess either way we need some documentation describing it along the above lines.
