22 The following modifiers are supported on Intel Ivy Bridge R3PQI 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 R3QPI 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 [0:15].
