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:

Enjoy,
