Hello,

I have released a new version of the perfmon base package.
This release is relative to 2.6.16-rc1.

Due to the addition of the migrate_pages() system call, all perfmon
system calls have been shifted by one. As a consequence, you must
relink your applications using the new version of libpfm which
is also released today: libpfm-3.2-060118.

This new kernel patch includes several important changes:

- added support for the Dual-Core Itanium 2 (Montecito) processor

- working support for MIPS5K and MIPS20k (by Phil Mucci)

- lots of cleanups in the PMU description modules. Some common
functionalities moved into core (masking of reserved fields)

- PFM_REGFL_NEMUL64 managed from perfmon core

The new version of the library, libpfm, includes the following changes:

- added support for MIPS5K, MIPS20K

- added pfm_get_event_counter() interface with man page

- added support for compiling using a 32-bit ABI on a 64-bit OS
(not available on all platforms, see config.mk)

- reworked all standalone examples

- cleanups and fixes in the generic examples

The two packages can be downloaded from the SourceForge website at:

I will be posting the patches directly to LKML for
review very shortly.

Enjoy,
