As far as I can tell, PciHostBridgeLib allows you to return an arbitrary number of PCI host bridges, each with their own segment number. I haven't tried it myself, but it is worth a try whether returning an array of all host bridges on your platform works as expected. _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
