NAME

       libpfm_amd64_fam1ah_zen5 - support for AMD64 Family 1Ah processors

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: amd64_fam1ah_zen5
       PMU desc: AMD64 Fam1Ah Zen5

DESCRIPTION

       The library supports AMD Family 1Ah processors Zen5 core PMU in both 32 and 64-bit modes.

MODIFIERS

       The following modifiers are supported on AMD64 Family 1Ah Zen5 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].
