Description

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

Modifiers

       The following modifiers are supported on Intel Ivy Bridge IRP 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 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].
