NAME

       libpfm_amd64_fam16h - support for AMD64 Family 16h processors

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: amd64_fam16h
       PMU desc: AMD64 Fam16h Zen

DESCRIPTION

       The library supports AMD Family 16h processors core PMU in both 32 and 64-bit modes.

MODIFIERS

       The following modifiers are supported on AMD64 Family 16h 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].
