Use RTC for PTU Statistical Callgraph?
Is it possible to use the real time clock, instead of the cpu clock performance counter, to collect statistical callgraph samples?  I'd like to compare the two callgraphs, rtc vs performance counter, to see which functions get preempted because of lock contention or I/O.

the answer is No as it is hardcoded now to use CPU performance timer.
