NAME         top

       libpfm_intel_bdx_unc_r2pcie  -  support for Intel Broadwell Server R2
       PCIe  uncore PMU

SYNOPSIS         top

       #include <perfmon/pfmlib.h>
       PMU name: bdx_unc_r2pcie
       PMU desc: Intel Broadwell Server R2 PCIe uncore PMU

DESCRIPTION         top

       The library supports the Intel Broadwell server R2 PCIe uncore PMU.
       This PMU model only exists on Broadwell server models (79, 86).

MODIFIERS         top

       The following modifiers are supported on Intel Broadwell server
       R2PCIe 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 R2PCIe 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].
       i      Invert the meaning of the threshold or edge filter. If set,
              the event counts when strictly less than N occurrences occur
              per cycle if threshold is set to N. When invert is set, then
              threshold must be set to non-zero value. If set, the event
              counts when the event transitions from occurring to not
              occurring (falling edge) when edge detection is set. This is a
              boolean modifier
