Abstract
In an embodiment, a translation of a hierarchical bus number to a physical bus number and a bridge identifier of a bridge are written to a north chip. A request is received that comprises an identifier of a destination. A determination is made that the identifier comprises the hierarchical bus number. In response to the determination, the identifier of the destination is replaced in the request with the physical bus number and the bridge identifier. The request is sent to the bridge identified by the bridge identifier. A south chip comprises the bridge, and the south chip is connected to the north chip via a point-to-point serial link. The physical bus number identifies a bus that connects the bridge to a device. The request comprises a configuration write request that requests a write of data to the device.
