Regarding the performance counter aspect, is there anyone starting any related work yet?

We have done some initial investigation internally a while back, but we are not actively working on it at the moment. On ARM the overhead of collecting PMU data for each task is quite low, but actually using these numbers for something useful requires some more research. We might take it up again at a later point in time.
