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].
