NAME

        libpfm_intel_p6 - support for Intel P5 based processors

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: pm, ppro, pii, piii, p6
       PMU desc: Intel Pentium M, Intel Pentium Pro, Intel Pentium II, Intel Pentium III, Intel P6

DESCRIPTION

       The  library  supports  all Intel P6-based processors all the way back to the Pentium Pro.
       Although all those processors offers the same PMU architecture, they differ in the  events
       they provide.

MODIFIERS

       The following modifiers are supported on all Intel P6 processors:

       u      Measure  at user level which includes privilege levels 1, 2, 3. This corresponds to
              PFM_PLM3.  This is a boolean modifier.

       k      Measure at kernel level which includes  privilege  level  0.  This  corresponds  to
              PFM_PLM0.  This is a boolean modifier.

       i      Invert  the  meaning  of  the event. The counter will now count cycles in which the
              event is not occurring. This is a boolean modifier

       e      Enable edge detection, i.e., count only when there is a state transition. This is a
              boolean modifier.

       c      Set  the  counter  mask value. The mask acts as a threshold. The counter will count
              the number of cycles in which the number of occurrences of the event is greater  or
              equal  to  the  threshold.  This  is  an  integer modifier with values in the range
              [0:255].
