Abstract
An apparatus and method for resetting a virtualized device are disclosed. The virtualized device may be coupled to a first port on a communication unit via a first link. The first port may send one or more instructions to the virtualized device via the first link using a first communication protocol. A processor may be configured to detect a reset condition for the virtualized device. In response to the detection of the reset condition for the virtualized device, the first port may disregard one or more transaction requests made by the virtualized device. The first port may further send an error message to the processor in response to receiving a Programmed Input/Output (PIO) request from the processor after the detection of the reset condition.
