MODIFIERS

21       The following modifiers are supported on Intel Skylake X  server  M3UQI
22       uncore PMU:
23
24       e      Enable  edge  detection,  i.e., count only when there is a state
25              transition from no occurrence of  the  event  to  at  least  one
26              occurrence. This modifier must be combined with a threshold mod‐
27              ifier (t) with a value greater or equal to one.  This is a bool‐
28              ean modifier.
29
30       t      Set  the  threshold  value.  When  set  to a non-zero value, the
31              counter counts the number of M3UPI cycles in which the number of
32              occurrences  of  the event is greater or equal to the threshold.
33              This is an integer modifier with values in the range [0:15].
34
35       i      Invert the meaning of the threshold or edge filter. If set,  the
36              event  counts  when  strictly  less than N occurrences occur per
37              cycle if threshold is set to N. When invert is set, then thresh‐
38              old must be set to non-zero value. If set, the event counts when
39              the event transitions from occurring to not  occurring  (falling
40              edge) when edge detection is set. This is a boolean modifier
