NAME

       libpfm_intel_hswep_unc_imc - support for Intel Haswell-EP Integrated Memory Controller (IMC)  uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: hswep_unc_imc[0-7]
       PMU desc: Intel Haswell-EP IMC uncore PMU

DESCRIPTION

       The  library  supports  the  Intel Haswell Integrated Memory Controller (IMC) uncore PMU.  This PMU model
       only exists on Haswell model 63.

MODIFIERS

       The following modifiers are supported on Intel Haswell C-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 IMC 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].  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
