NAME

       libpfm_amd64_fam17h - support for AMD64 Family 17h processors

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: amd64_fam17h (deprecated), amd_fam17h_zen1
       PMU desc: AMD64 Fam17h Zen1

DESCRIPTION

       The  library  supports  AMD  Family  17h  processors  Zen1  core  PMU  in  both 32 and 64-bit modes.  The
       amd64_fam17h PMU model name has been deprecated in favor of amd_fam17h_zen1. The old name  is  maintained
       for backward compatibility reasons, but should not be used anymore.

MODIFIERS

       The following modifiers are supported on AMD64 Family 17h Zen1 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].
