[PATCH v6 0/2] vhost-vdpa: add support for vIOMMU

Posted by Cindy Lu 1 year, 6 months ago

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.

changes in V6
move the error_report for the unpopulated discard back to
memeory_get_xlat_add
