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].
