Description

       The  library  supports the Intel Ivy Bridge R2 PCIe uncore PMU.  This PMU model only exists on Ivy Bridge
       model 62.

Modifiers

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

       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].
