[PATCH RFC v2 0/4] vdpa: decouple reset of iotlb mapping from device reset
In order to reduce needlessly high setup and teardown cost
of iotlb mapping during live migration, it's crucial to
decouple the vhost-vdpa iotlb abstraction from the virtio
device life cycle, i.e. iotlb mappings should be left
intact across virtio device reset [1]. For it to work, the
on-chip IOMMU parent device should implement a separate
.reset_map() operation callback to restore 1:1 DMA
