That's exactly what I mean. I assume that BAR entries must be written
pointing to an absolute memory area in dom0 which will then be mapped
into the PV as this provides the greatest flexibility. Is this
correct? Or do I just enable a memory area in the PV and map the BAR
to the buffers physical address?
