NAME

       libpfm_intel_bdx_unc_r3qpi - support for Intel Broadwell Server R3QPI uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: bdx_unc_r3qpi[0-2]
       PMU desc: Intel Broadwell server R3QPI uncore PMU

DESCRIPTION

       The  library supports the Intel Broadwell server R3QPI uncore PMU.  This PMU model only exists on various
       Broadwell server models (79, 86).

MODIFIERS

       The following modifiers are supported on Intel Broadwell server 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].

       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
