+
+If the `OPAL_PM_SLEEP_ENABLED_ER1` bit is set on a stop state, then this OPAL
+call needs to be made upon entry and exit of stop state.
+This is currently needed for the `fastsleep_` idle state, present on POWER8
+systems.

+
+:ref:`OPAL_SUCCESS`
+     Applied workaround
+:ref:`OPAL_PARAMETER`
+     Invalid state or enter/exit.
