Subject: 2.6.26 new perfmon kernel patch + libpfm + pfmon available

Hello,

I have released the perfmon2 kernel patch for kernel v2.6.26. There is
no new major features.  Concerning the merge with mainline, we use a different
code base which contains only code to  supports only per-thread counting on
X86 processors. The patch is distributed as a quilt patchset and is
posted on LKML.

Here are some of the kernel changes:
 - Support for Intel architectural perfmon v3 (as per IA-32 Vol3b June 2008)
 - base syscall exported in /sys/kernel/perfmon/syscall
 - experimental utrace support
 - added dep_pmcs[] to PMD definitions to avoid picking up stale config
 - important IBM Power updates to solve counter overflow issues (Corey Ashford)
 - AMD64 APIC/PCI cleanups for IBS support (Robert Richter)
 - new API for handler routine of sampling formats to accomodate IBM
Cell (Carl Love)

There is also a new release for libpfm, now at version 3.5.
The changes include:
 - support for AMD K7 (Vince Weaver)
 - support for Intel architectural perfmon v3
 - support for SiCortex (ICA9A, ICA9B) (Phil Mucci)
 - dynamic perfmon syscall support via /sys
 - new environment variable to control debugging and force particular PMU model

Finally, a new major version of pfmon, now at pfmon-3.5 with some minor
changes:
 - group unknown symbols as UNKNOWN when sampling (Andrzej Nowak)
 - lots of bug fixes

As usual all files and more detailed changelogs can be downloaded from our
website at:
