NAME

       libpfm_intel_snbep_unc_imc   -   support  for  Intel  Sandy  Bridge-EP  Integrated  Memory
       Controller (IMC)  uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: snbep_unc_imc[0-3]
       PMU desc: Intel Sandy Bridge-EP IMC uncore PMU

DESCRIPTION

       The library supports the Intel Sandy Bridge Integrated Memory Controller (IMC) uncore PMU.
       This PMU model only exists on Sandy Bridge model 45. There are four IMC PMUs per socket.

MODIFIERS

       The following modifiers are supported on Intel Sandy Bridge C-Box uncore PMU:

       i      Invert the meaning of the event. The counter will now count IMC cycles in which the
              event is not occurring. This is a boolean modifier

       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].
