When I added VT-d support for PV guests I made xend do the device
assignment iff the destination was a PV domain. Is there any reason
why device assignment can not be performed by xend for HVM guests as
well?
Other resource assignment (IOMEM and IRQs) still seems to happen in
xend for HVM guests as well as for PV guest. What other domctls does
ioemu need to perform?
ioemu needs to update the mappings, see the pt_iomem_map() function.
I suggest the domctls should set up access permissions (e.g., by use of
existing iomem_premission domctl). And then extend XENMEM_add_to_physmap to
allow (re-)mapping of permitted I/O ranges into pseudophysical address
space. The new passthru-specific domctls may well be ill conceived.
