DESCRIPTION

18       The  library supports AMD Family 15h processors core PMU in both 32 and
19       64-bit modes. The uncore (NorthBridge) PMU is also supported as a sepa‐
20       rate PMU model.

MODIFIERS

24       The following modifiers are supported on AMD64 Family 15h core PMU:
25
26       u      Measure  at  user level which includes privilege levels 1, 2, 3.
27              This corresponds to PFM_PLM3.  This is a boolean modifier.
28
29       k      Measure at kernel level which includes privilege level  0.  This
30              corresponds to PFM_PLM0.  This is a boolean modifier.
31
32       h      Measure  at while executing in host mode (when using virtualiza‐
33              tion). This corresponds to PFM_PLMH.  This modifier is available
34              starting with Fam10h. This is a boolean modifier.
35
36       g      Measure at while executing in guest mode (when using virtualiza‐
37              tion). This modifier is available starting with Fam10h. This  is
38              a boolean modifier.
39
40       i      Invert  the  meaning  of  the  event. The counter will now count
41              cycles in which the event is not occurring. This  is  a  boolean
42              modifier
43
44       e      Enable  edge  detection,  i.e., count only when there is a state
45              transition. This is a boolean modifier.
46
47       c      Set the counter mask value. The mask acts as  a  threshold.  The
48              counter  will  count the number of cycles in which the number of
49              occurrences of the event is greater or equal to  the  threshold.
50              This is an integer modifier with values in the range [0:255].
51
52       The uncore (NorthBridge) PMU does not support any modifiers.
