Zusammenfassung:A circuit at an interface between a device and an interconnect fabric is configured to track outstanding transactions associated with the device and ensure the completion of the outstanding transactions before rebooting or powering down the device. In some embodiments, the circuit is also configurable to provide appropriate responses when the device is powered down or is being rebooted such that other devices in the system can still operate even without knowing that the device is inactive and would not hang because no response is received from the device.
