The following announcement of a portable library for using the hardware
performance counters of different processors might be a good starting point.

///////////////////////////////////////////////////////////////////////////////
PCL - The Performance Counter Library
Version 1.1, October 1998
PCL (The Performance Counter Library) is a common interface to access
performance counters built into modern microprocessors in a portable
way. PCL supports query for functionality, start and stop of counters,
and reading the current values out of the counters. Performance counting
can be done in user mode, system, and user-or-system mode. Functions
are callable from C, C++, and Fortran.
Currently, the following systems are supported:
- SUN Solaris 2.x with UltraSPARC I,II
- Linux 2.0.x and 2.1.x with Pentium/PPro/Pentium II
- Digital Unix with Alpha 21164
- Cray T3E with Alpha 21164
- SGI IRIX with R10000
- IBM AIX with PowerPC 604e
The homepage of PCL can be found at
http://www.fz-juelich.de/zam/PT/ReDec/SoftTools/PCL/PCL.html
were you can find the source and a detailled description of PCL
(including a description of performance counters on various
microprocessors).
The software is copyrighted.
Copyright 1998 by Central Institute for Applied Mathematics, Research
Centre Juelich, Germany.
For research purposes, PCL is free. If you want to use it
commercially, please contact us (see homepage).
PCL uses the following packages (see the documentation for details):
- Linux : libpperf (M. Patrick Goda, Michael S. Warren)
and the msr-device (Stephan Meyer)
- Solaris: perfmon (Richard Enbody)
- AIX : PMapi (IBM)
Have fun,
