Measuring context swap time

[Vaughn Clinton]

There might be an example in kprobes or systemTap that you can follow.

Hi All,

I am a Linux kernel newbie. Now I want to write a kernel module that can measure the context swap time between two processes using hrtimer.
How do I implement this?
More specifically,  how do I access different processes in kernel module. I've read Linux kernel module programming guide but still don't have a clue.

Is there any other useful references on Linux kernel modules?

Any help will be greatly appreciated.

Eddie
