NAME

       libpfm_intel_ivbep_unc_qpi - support for Intel Ivy Bridge-EP QPI uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: ivbep_unc_qpi0, ivbep_unc_qpi1
       PMU desc: Intel Ivy Bridge-EP QPI uncore PMU

DESCRIPTION

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

MODIFIERS

       The following modifiers are supported on Intel Ivy Bridge QPI 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 QPI 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].
