how to measure execution time in kernel space?
 
i have registered a handler, in a kernel module, to deal with some incomming ethernet packages of a specific type .. is it possible to measure the execution of that handler in cpu clock ticks or any other microsecond precise clocking scheme?

Use clock defined in time.h as clock_t clock(void) to get clock time. To get time in seconds divide it by CLOCKS_PER_SEC.

If you want more details, such as user time,system time etc. Use times() defined in times.h
