NAME

       libpfm_intel_core - support for Intel Core-based processors

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: core
       PMU desc: Intel Core

DESCRIPTION

       The library supports all Intel Core-based processors that includes models 15, 23, 29.

MODIFIERS

       The following modifiers are supported on Intel Core 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 from no occurrence of the
              event  to at least one occurrence. This modifier must be combined with a counter mask modifier (m)
              with a value greater or equal to one.  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].
