AMD IOMMU Extended Feature (EFR) and Extended Feature 2 (EFR2) registers specify features supported by each IOMMU hardware instance. The IOMMU driver checks each feature-specific bits before enabling each feature at run time. For IOMMUFD, the hypervisor passes the raw value of amd_iommu_efr and amd_iommu_efr2 to VMM via iommufd IOMMU_DEVICE_GET_HW_INFO ioctl.
