NAME

       libpfm_amd64_fam15h - support for AMD64 Family 15h processors

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: amd64_fam15h_interlagos
       PMU desc: AMD64 Fam15h Interlagos
       PMU name: amd64_fam15h_nb
       PMU desc: AMD64 Fam15h Northbridge

DESCRIPTION

       The  library  supports AMD Family 15h processors core PMU in both 32 and 64-bit modes. The
       uncore PMU (Northbridge) is also supported as a separate PMU model.

MODIFIERS

       The following modifiers are supported on AMD64 Family 15h 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].

       The uncore (NorthBridge) PMU does not support any modifiers.
