Subject: Interrupt Latency test for intel machine

Hello all,

On my Intel Pentium 4 CPU 2.40 GHz machine by using attached file, I
am getting Interrupt latency as follows :-

Configuration               MAX (us)        MIN (us)        AVG (us)
     Samples
-------------                      --------             --------
      --------            -------------
PREEMPT-NONE            43.576          4.190           4.190           119343

Voluntary PREEMPT       44.414          4.190           4.190           108694

PREEMPT low-latency     39.398          4.190           5.028           112717

Thank you,

Jaswinder Singh.
