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].
