NAME

       libpfm_amd64_k8 - support for AMD64 K8 processors

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: amd64_k8_revb, amd64_k8_revc, amd64_k8_revd, amd64_k8_reve, amd64_k8_revf, amd64_k8_revg
       PMU desc: AMD64 K8 RevB, AMD64 K8 RevC, AMD64 K8 RevD, AMD64 K8 RevE, AMD64 K8 RevF, AMD64 K8 RevG

DESCRIPTION

       The library supports AMD K8 processors in both 32 and 64-bit modes. They correspond to processor family 15.

MODIFIERS

       The following modifiers are supported on AMD64 K8 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 occur-
	      rences of the event is greater or equal to the threshold. This is an integer modifier with values in the range [0:255].
