I have released another version of the perfmon new code base package.
This release is still relative to 2.6.17-rc4. This is a cumulative
patch, you don't need the previous patch.

This patch introduces two new major features requested by users:

- support for IA-32 architected PMU as described by the latest
IA-32 architecture manuals. You need at least a Core Duo/Solo
processors or newer for this to work.

- a kernel level interface (kapi) to allow kernel code to call
perfmon2 for counting and sampling. Only system-wide measurements
are supported. Read comments at the top of perfmon_kapi.c

- PMD write checkers routines for PMU description tables

I have also released a new version of the user library libpfm: libpfm-3.2-060522.
It includes bug fixes for the architected IA-32 PMU support.

Finally, I have released a new version of the pfmon tool. This new version
- support for IA-32 architected PMU (includes Core Duo/Solo processors)
- bug fixes in the i386 P6/PM support

This version of pfmon-3.2 requires libpfm-3.2-060522.

You can grab the new packages at our web site:


The libpfm and pfmon source code is also available in our CVS repository
accessible from our home page.
