- * Notes:
- *  This file manages the benchmark timer used by the RTEMS Timing Test
- *  Suite.  Each measured time period is demarcated by calls to
- *  benchmark_timer_initialize() and benchmark_timer_read().  benchmark_timer_read() usually returns
- *  the number of microseconds since benchmark_timer_initialize() exitted.
- *
- *  It is important that the timer start/stop overhead be determined
- *  when porting or modifying this code.
