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].
