Specifically, from the PCI host's perspective, how do you know what you are dealing with (presumably PCI VID:DID:SVID:SID?) How exactly does the mapping of PCI BARs and INT/MSI/MSI-X channels to the slave device play in? I think it is safe to say that the device models we have today simply don't account for this kind of usage, which, as you say, is a genuine problem, and I think we need to understand the problem space better in order to properly architect the solution, as I don't think we have one right now. -hpa -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
