10.1.4: Set_find_average_overhead

This routine is invoked by the "Check Timer" (tmck) test in the RTEMS Timing Test Suite. It makes the Read_timer routine NOT subtract the overhead required to initialize and read the benchmark timer. This is used by the tmoverhd test to determine the overhead required to initialize and read the timer.

void Set_find_average_overhead(rtems_boolean find_flag)
{
    disable the subtract overhead feature
}

The Timer_driver_Find_average_overhead variable is usually used to indicate the state of the "subtract overhead feature".
