Bug Description
Description:
Intel IOMMU scalable mode is proposed in the new IOMMU spec. It provides two level address translation based on a PASID. With this translation mode, a PASID-capable PCIe device could pass through partial of its resource (also called AI, Assignment Instance) to the guest VM with fully IOMMU protection and isolation. It’s the key for a platform in order to support SIOV.
