i want to measure time spend in a callback function called from
interrupt context .
since the time spend will be in us / ns , what kernel apis can i use
to measure it ?
also since i want to use it in interrupt context , kernel time
measurement apis should not sleep .
i am using embedded arm target , and tools like OProfile are not available .
can i be guided which kernel time measurement apis shall i use to
measure time in a interrupt callback ?
