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  modi-
	      fier

       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  occur-
	      rences of the event is greater or equal to the threshold.  This is an integer modifier with values in the range [0:255].
