NAME

       libpfm_intel_snbep_unc_r2pcie - support for Intel Sandy Bridge-EP R2 PCIe  uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: snbep_unc_r2pcie
       PMU desc: Intel Sandy Bridge-EP R2 PCIe uncore PMU

DESCRIPTION

       The  library  supports  the  Intel  Sandy Bridge R2 PCIe uncore PMU.  This PMU model only exists on Sandy
       Bridge model 45. There is only one R2PCIe PMU per processor socket.

MODIFIERS

       The following modifiers are supported on Intel Sandy Bridge R2PCIe uncore PMU:

       i      Invert the meaning of the event. The counter will now count R2 PCIe 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  R2PCIe
              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 [0:15].
