The timer interrupt does the trick.. whenever a timer interrupt occurs the count variable of the process that is running gets decremented.. and when it reaches 0, it sets the need_reschedule. Before leaving the interrupt it checks the need_reschedule flag and if it is set it will call the schedule function.
