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: http://perfmon2.sourceforge.net Enjoy,
