NAME

       libpfm_intel_ivbep_unc_r3qpi - support for Intel Ivy Bridge-EP R3QPI uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: ivbep_unc_r3qpi0, ivbep_unc_r3qpi1, ivbep_unc_r3qpi2
       PMU desc: Intel Ivy Bridge-EP R3QPI uncore PMU

DESCRIPTION

       The library supports the Intel Ivy Bridge R3QPI uncore PMU.  This PMU model only exists on
       Ivy Bridge model 62.

MODIFIERS

       The following modifiers are supported on Intel Ivy Bridge R3PQI  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 R3QPI 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
              [0:15].
