Abstract
Methods and systems are disclosed herein for providing a universal PCIe port. The same port can be configured to accept a PCIe component as a host or an endpoint (device) symmetrically. The PCIe port can be connected to the host interface or the root complex interface if the PCIe connection is to be configured as a host or an endpoint, respectively. A virtual topology can be provided for a host that associates the host with corresponding endpoints. A mapping between virtual addresses of the corresponding endpoints in the virtual topology and local addresses of the corresponding endpoints is provided.
