+Kick off the requested PCI reset operation. This starts a state machine off to
+perform the requested operation. This call will return how many milliseconds to
+wait before calling back into :ref:`OPAL_PCI_POLL`. An OS can
+call :ref:`OPAL_PCI_POLL` earlier, but it is unlikely any progress will have
+been made.
+
+
+Returns
+-------
+
+:ref:`OPAL_PARAMETER`
+     Invalid ``id``, ``reset_scope``, or ``assert_state``.
+:ref:`OPAL_UNSUPPORTED`
+     Operation is unsupported on ``id``.
+value > 0
+     How many ms to wait for the state machine to crank.
+     Call :ref:`OPAL_PCI_POLL` to crank the state machine further.
