Probably smu firmware doesn't expose the feature mask to driver. Can you confirmware with smu firmware guy whehter this feature is really disabled or not in SMU12. If that, in my view, issue the message SMU_MSG_SetWorkloadMask with an unsupported state, it doesn't make sense. Just work around this with one time warnning is not a good solution.
