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. changes in V6 move the error_report for the unpopulated discard back to memeory_get_xlat_addr changes in V7 organize the error massage to avoid the duplicate information changes in V8 Organize the code follow the comments in the last version changes in V9 Organize the code follow the comments Cindy Lu (2): vfio: move implement of vfio_get_xlat_addr() to memory.c vhost-vdpa: add support for vIOMMU hw/vfio/common.c | 66 ++---------------- hw/virtio/vhost-vdpa.c | 123 ++++++++++++++++++++++++++++++--- include/exec/memory.h | 4 ++ include/hw/virtio/vhost-vdpa.h | 10 +++ softmmu/memory.c | 72 +++++++++++++++++++ 5 files changed, 203 insertions(+), 72 deletions(-) -- 2.34.3
