NAME

       libpfm_intel_bdx_unc_r2pcie - support for Intel Broadwell Server R2 PCIe  uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: bdx_unc_r2pcie
       PMU desc: Intel Broadwell Server R2 PCIe uncore PMU

DESCRIPTION

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

MODIFIERS

       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
