NAME

       libpfm_intel_coreduo - support for Intel Core Duo/Solo processors

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: coreduo
       PMU desc: Intel Core Duo

DESCRIPTION

       The  library  supports  all  Intel Yonah-based processors such as Intel Core Duo and Intel
       Core Solo processors.

MODIFIERS

       The following modifiers are supported on Intel Core Duo 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].

ENVIRONMENT VARIABLES

       It   is   possible   to  force  activation  of  the  Intel  Core  Duo  support  using  the
       LIBPFM_FORCE_PMU variable.  The PMU name, coreduo, must be passed. No  additional  options
       are supported.
