Имя (Name)

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

Синопсис (Synopsis)

#include <perfmon/pfmlib.h>


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

Описание (Description)

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

Модификаторы (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].
