These patches are to support vIOMMU in vdpa device changes in V3 1. Move function vfio_get_xlat_addr to memory.c 2. Use the existing memory listener, while the MR is iommu MR then call the function iommu_region_add/ iommu_region_del
changes in V4 1.make the comments in vfio_get_xlat_addr more general changes in V5 1. Address the comments in the last version 2. Add a new arg in the function vfio_get_xlat_addr, which shows whether the memory is backed by a discard manager. So the device can have its own warning.
