DESCRIPTION

17       The library supports the Intel Broadwell server  R2  PCIe  uncore  PMU.
18       This PMU model only exists on Broadwell server models (79, 86).

MODIFIERS

22       The  following modifiers are supported on Intel Broadwell server R2PCIe
23       uncore 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 R2PCIe cycles in which the number
33              of occurrences of the event is greater or equal to  the  thresh‐
34              old.   This  is  an  integer  modifier  with values in the range
35              [0:15].
36
37       i      Invert the meaning of the threshold or edge filter. If set,  the
38              event  counts  when  strictly  less than N occurrences occur per
39              cycle if threshold is set to N. When invert is set, then thresh‐
40              old must be set to non-zero value. If set, the event counts when
41              the event transitions from occurring to not  occurring  (falling
42              edge) when edge detection is set. This is a boolean modifier
