Actually it seems like it's not counting time properly if I run my test
multiple times in a row:
# /root/testusb -t 1 -c 100000 -s 2048 -a
# head -3 trace_stat/function0
Function Hit Time Avg s^2
-------- --- ---- --- ---
thread_interrupt 174876 166120839 us 949.935 us 3048498 us
# /root/testusb -t 1 -c 100000 -s 2048 -a
# head -3 trace_stat/function0
Function Hit Time Avg s^2
-------- --- ---- --- ---
dwc3_thread_interrupt 286796 967267300 us 4190545199 us 3241109 us
# /root/testusb -t 1 -c 100000 -s 2048 -a
# head -3 trace_stat/function0
Function Hit Time Avg s^2
-------- --- ---- --- ---
dwc3_thread_interrupt 401346 642632072 us 1601.192 us 1194316 us
and so on...
