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
