AFAIK, memory table usually contain just few entries, the performance
cost should be fine. (At least should be the same as the case of VFIO).
So in qemu, simply hooking add_region/remove_region to
VHOST_IOTLB_UPDATE/VHOST_IOTLB_INVALIDATE should work?
If we introduce API like you proposed previously (memory listener style):
begin
add
remove
commit
I suspect it will be too heavweight for the case of vIOMMU and for the
driver that want to build new mapping, we need addnop etc...
Thank...
