Hi All,

          In my driver code I have interrupt which is exactly 1 sec(gps-pps),
          I want the data to be copied (copy_to_user) to the user space through read function,After the elapse of interrupt(1 sec gps-pps),how do I instantiate read function after elapse interrupt,Can anybody please share idea,

Regards
