We've had and still have too many issues where the gpu turbot doesn't quite to what it's supposed to do (or what we want it to do). Adding a tracepoint to track when the desired gpu frequence changes should help a lot in characterizing and understanding problematic workloads. Also, this should be fairly interesting for power tuning (and especially noticing when the gpu is stuck in high frequencies, as has happened in the past) and hence for integration into powertop and similar tools.

I can't help but think it's equally interesting to know when the queue the work as well.
