NAME

       libpfm_amd64_fam10h - support for AMD64 Family 10h processors

SYNOPSIS

       #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

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

MODIFIERS

       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 occur-
	      rences of the event is greater or equal to the threshold. This is an integer modifier with values in the range [0:255].
