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.
