Review comment:
       @pkarashchenko 
   
   Perf timer interface generally uses the hardware cycle counter
   provided by the arch chip directly(such as DWT_CYCCNT(cortex-m)),
   CYCCNT is a free running counter and counting upwards.
   It wraps around to 0 on overflow.
   
   I have update the description on commit message, please review again
