ABSTRACT:
A register access request for control and/or status operations from a link is detected using a hardware mechanism and is forwarded to a software-controlled entity for access to a virtual register for control and/or status operations. The software-controlled entity can provide virtual registers in memory associated with the software-controlled entity. The hardware mechanism can form part of an interconnect device and the software-controlled entity is external to the interconnect device.
