Right, but I'd expect that should be something that the driver can generally do based on knowledge of what it needs to deliver to its users. It doesn't need to be tunable to that - for example, input devices will have a reasonable idea of the response time needed to deliver interactive performance. If it's really got no idea then hopefully not providng any constraints will do something sensible. _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
