NAME

       libpfm_amd64_k7 - support for AMD64 K7 processors

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: amd64_k7
       PMU desc: AMD64 K7

DESCRIPTION

       The  library  supports AMD K7 processors in both 32 and 64-bit modes. They correspond to processor family
       6.

MODIFIERS

       The following modifiers are supported on AMD64 K7 processors:

       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.

       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].
