MODIFIERS

22       The  following  modifiers  are  supported on AMD64 Family 17h Zen2 core
23       PMU:
24
25       u      Measure at user level which includes privilege levels 1,  2,  3.
26              This corresponds to PFM_PLM3.  This is a boolean modifier.
27
28       k      Measure  at  kernel level which includes privilege level 0. This
29              corresponds to PFM_PLM0.  This is a boolean modifier.
30
31       h      Measure at while executing in host mode (when using  virtualiza‐
32              tion). This corresponds to PFM_PLMH.  This modifier is available
33              starting with Fam10h. This is a boolean modifier.
34
35       g      Measure at while executing in guest mode (when using virtualiza‐
36              tion).  This modifier is available starting with Fam10h. This is
37              a boolean modifier.
38
39       i      Invert the meaning of the event. The counter will now count  cy‐
40              cles in which the event is not occurring. This is a boolean mod‐
41              ifier
42
43       e      Enable edge detection, i.e., count only when there  is  a  state
44              transition. This is a boolean modifier.
45
46       c      Set  the  counter  mask value. The mask acts as a threshold. The
47              counter will count the number of cycles in which the  number  of
48              occurrences  of  the event is greater or equal to the threshold.
49              This is an integer modifier with values in the range [0:255].
