Hi! That's correct. We need a way to have a chunk of what Linux calls "Reserved" memory for the virtual BAR trick. Currently, PCIem only thinks about a single device (Since I first needed to have something that worked in order to check how feasible this all was), but there's planned support for multiple devices that can share a "Reserved" memory pool dynamically so you can have multiple BARs for multiple devices.
