Technically, we can keep the incremental API here and let the vendor vDPA drivers to record the full mapping internally which may slightly increase the complexity of vendor driver.What will be the trigger for the driver to know it received the last mapping on this series and it can now push it to the on-chip IOMMU?
Some kind of invalidate API? -- MST
