How to calculate how many times a function runs?????
 

Hi all:
I have a function in a kernel module and I want to see how many times it is called and runs per second. I add a counter in the function so once it runs, counter+=1; is there any timer or something which can check this counter every second???Thanks very much.

The answer depends on what programming language it is, with which you are writing the code.
Did I perhaps miss in your question, someplace where you gave us that information?

I'm writing a kernel function so I use c++/c.

Use timers provided by the Linux kernel. First Google hit for "linux kernel timer" gives http://makelinux.com/ldd3/chp-7-sect-4 .
