Summary:Disclosed are various approaches for exposing peripheral component interconnect express (PCIe) configuration space implementations as Enhanced Configuration Access Mechanism (ECAM)-compatible. In some examples, a bridge device is identified on a segment corresponding to a root complex of a computing device. An endpoint device is connected to a bus downstream from the bridge device. A synthetic segment identifier is assigned to the bus once the endpoint device is identified as connected to the bus. Synthetic address data is generated for the endpoint device. The synthetic address data includes the synthetic segment identifier for the bus and sets a bus identifier of the bus to zero regardless of a hierarchical position of the bus in a standard peripheral component interconnect express (PCIe) bus hierarchy.
