       The library supports AMD Family 19h processors Zen3 core PMU in both 32 and 64-bit modes.

       The following modifiers are supported on AMD64 Family 19h Zen3 core PMU:

       u      Measure at user level which includes privilege levels 1, 2, 3. This corresponds to PFM_PLM3.  This
              is a boolean modifier.

       k      Measure at kernel level which includes privilege level 0. This corresponds to PFM_PLM0.  This is a
              boolean modifier.

       h      Measure at while executing in host mode (when using virtualization). This corresponds to PFM_PLMH.
              This modifier is available starting with Fam10h. This is a boolean modifier.

       g      Measure  at  while executing in guest mode (when using virtualization). This modifier is available
              starting with Fam10h. This is a boolean modifier.

       i      Invert the meaning of the event. The counter will now count cycles  in  which  the  event  is  not
              occurring. This is a boolean modifier

       e      Enable  edge  detection,  i.e.,  count  only  when  there is a state transition. This is a boolean
              modifier.

       c      Set the counter mask value. The mask acts as a threshold. The counter will  count  the  number  of
              cycles  in which the number of occurrences of the event is greater or equal to the threshold. This
              is an integer modifier with values in the range [0:255].
