NAME

       libpfm_intel_ivbep_unc_irp - support for Intel Ivy Bridge-EP IRP uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: ivbep_unc_irp
       PMU desc: Intel Ivy Bridge-EP IRP uncore PMU

DESCRIPTION

       The library supports the Intel Ivy Bridge uncore PMU.  This PMU model only exists on Ivy Bridge model 62.

MODIFIERS

       The following modifiers are supported on Intel Ivy Bridge IRP uncore PMU:

       e      Enable edge detection, i.e., count only when there is a state transition from no occurrence of the
              event to at least one occurrence. This modifier must be combined with  a  threshold  modifier  (t)
              with a value greater or equal to one.  This is a boolean modifier.

       t      Set  the threshold value. When set to a non-zero value, the counter counts 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].
