21 The following modifiers are supported on AMD64 Family 16h core PMU:
22
23 u Measure at user level which includes privilege levels 1, 2, 3.
24 This corresponds to PFM_PLM3. This is a boolean modifier.
25
26 k Measure at kernel level which includes privilege level 0. This
27 corresponds to PFM_PLM0. This is a boolean modifier.
28
29 h Measure at while executing in host mode (when using virtualiza‐
30 tion). This corresponds to PFM_PLMH. This modifier is available
31 starting with Fam10h. This is a boolean modifier.
32
33 g Measure at while executing in guest mode (when using virtualiza‐
34 tion). This modifier is available starting with Fam10h. This is
35 a boolean modifier.
36
37 i Invert the meaning of the event. The counter will now count
38 cycles in which the event is not occurring. This is a boolean
39 modifier
40
41 e Enable edge detection, i.e., count only when there is a state
42 transition. This is a boolean modifier.
43
44 c Set the counter mask value. The mask acts as a threshold. The
45 counter will count the number of cycles in which the number of
46 occurrences of the event is greater or equal to the threshold.
47 This is an integer modifier with values in the range [0:255].
