* The following requires some clarification. Despite the fact that both
* RUN_TRIGGER and STOP_TRIGGER have the word "TRIGGER" in their
* names, only one is actually a trigger, and that is the STOP_TRIGGER.
* Merely writing a 1(_TASK) to the RUN_TRIGGER is not sufficient to
* resume the gpu - the _STOP_TRIGGER must explicitly be set to 0
* (_DISABLE) as well.
* Advice from the arch group: Disable the stop trigger first, as a
* separate operation, in order to ensure that the trigger has taken
* effect, before enabling the run trigger.
