NAME         top

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

SYNOPSIS         top

       #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         top

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

MODIFIERS         top

       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].
