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.

Abstract: An apparatus and method for controlling a device with shared hardware resources to provide separate execution environments for control and data functions are disclosed. A processor may be configured to generate a first request to access control functions of the device in response to execution of a first thread, and generate a second request to access data functions of the device in response to execution of a second thread. A communication unit may send first indicative of the first request and second data indicative of the second request to the device via first and second ports, respectively.

Abstract: An apparatus and method for controlling a virtualized endpoint device are disclosed. A processor may be configured to execute instructions included in multiple execution threads. A first device may be configured to perform multiple command and data functions, and a communication unit may include a first port coupled to the first device via a first link and be configured to send instructions from the processor to the first device via the first link using a first communication protocol. The processor may be further configured to execute first and second sets of commands included in respective execution threads. The first set of commands may be associated with the plurality of command functions and the second set of commands may be associated with the plurality of data functions.
