       libpfm_amd64_fam10h - support for AMD64 Family 10h processors

SYNOPSIS         top

       #include <perfmon/pfmlib.h>

       PMU name: amd64_fam10h_barcelona, amd64_fam10h_shanghai, amd64_fam10h_istanbul
       PMU desc: AMD64 Fam10h Barcelona, AMD64 Fam10h Shanghai, AMD64 Fam10h Istanbul

DESCRIPTION         top

       The library supports AMD Family 10h processors in both 32 and 64-bit
       modes. They correspond to processor family 16.

MODIFIERS         top

       The following modifiers are supported on AMD64 Family 10h (16)
       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.

       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].
