Hi,
I used to do this kind of measurement with a GPIO and an oscilloscope
set up in persistence mode. In this case ,the precision of the measure
doesn't depend of the timer's resolution.

Hi,
I am working on trying to measure the worst case processing time for
hard IRQ and soft IRQ. Well, I understand that we could use time
stamps at entry and exit to measure this. Just wanted to know if there
were other standard ways of measuring this. Any suggestions?
Thanks
Riyaz
