You mean the BAR values and such? 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?
