NAME

       libpfm_intel_hswep_unc_sbo - support for Intel Haswell-EP S-Box uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: hswep_unc_sbo
       PMU desc: Intel Haswell-EP S-Box uncore PMU

DESCRIPTION

       The  library  supports the Intel Haswell Rrint Transfer unit (S-Box) uncore PMU.  This PMU
       model only exists on Haswell model 63.

MODIFIERS

       The following modifiers are supported on Intel Haswell S-Box 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 HA 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
