MODIFIERS

21       The following modifiers are supported on Intel  Skylake  X  server  UPI
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 QPI 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 [0:255].
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
41
42

BASIC_HDR_MATCH events

44       The   library   also   supports  the  special  RXL_BASIC_HDR_MATCH  and
45       TXL_BASIC_HDR_MATCH opcode matcher events. These events have a lot more
46       filters  available  in  the form of either a modifier (listed below) or
47       specific umasks.  The following modifiers are available  in  additional
48       to the standard listed above:
49
50       rcsnid Specify a RCS Node identifier as an integer in the range [0-15].
51              Default: 0
52
53       dnid   Specify a destination Node identifier as an integer in the range
54              [0-15]. Default: 0
