MODIFIERS

22       The  following modifiers are supported on Intel Ivy Bridge C-Box uncore
23       PMU:
24
25       e      Enable edge detection, i.e., count only when there  is  a  state
26              transition  from  no  occurrence  of  the  event to at least one
27              occurrence. This modifier must be combined with a threshold mod‐
28              ifier (t) with a value greater or equal to one.  This is a bool‐
29              ean modifier.
30
31       t      Set the threshold value. When  set  to  a  non-zero  value,  the
32              counter  counts  the number of IMC cycles in which the number of
33              occurrences of the event is greater or equal to  the  threshold.
34              This is an integer modifier with values in the range [0:255].
