bit tracking? If not, I don't suggest to make this as a generic IOMMU
interface.
There is an implicit requirement for such interfaces.

Take an extreme example, if DMA writes one byte, under 1G mapping, the
dirty amount reported is 1G, but under 4K mapping, the dirty amount is

Block(largepage) mapping is not a proper granule for dirty log tracking.
Take an extreme example, if DMA writes one byte, under 1G mapping, the
dirty amount reported is 1G, but under 4K mapping, the dirty amount is
just 4K.
This adds a new interface named iommu_split_block in IOMMU base layer.
