NAME         top

        libpfm_intel_p6 - support for Intel P5 based processors

SYNOPSIS         top

       #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         top

       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         top

       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].
