Abstract
An I/O device having function level reset functionality includes a host interface that may include a master reset unit, a plurality of client interfaces, each corresponding to one or more functions, and a plurality of hardware resources. Each hardware resource may be associated with a respective function. In response to receiving a reset request to reset a specific function, the master reset unit may provide to each client interface, a request signal corresponding to the reset request, and a signal identifying the specific function. Each client interface having an association with the specific function may initiate a reset operation of the associated hardware resources, and also provide a client reset done signal for the specific function to the master reset unit in response to completion of the reset operations of the hardware resources. The master reset unit provides a reset done signal for the specific function to the host interface.
