The nested domain is allocated with IOMMU_DOMAIN_NESTED type to store stage-1 translation (i.e. GVA->GPA). This includes the GCR3 root pointer table along with guest page tables. The struct iommu_hwpt_amd_guest contains this information, and is passed from user-space as a parameter of the struct iommu_ops.domain_alloc_nested().
