NAME

       libpfm_intel_knc - support for Intel Knights Corner

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: knc
       PMU desc: Intel Knights Corner

DESCRIPTION

       The library supports Intel Knights Corner processors.

MODIFIERS

       The following modifiers are supported on Intel Knights Corner 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].

       t      Measure  on  all  threads  at the same time assuming hyper-threading is enabled. This is a boolean
              modifier.
