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