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].
