There were many improvements in this new version:

• new AMD Fam15h support (thanks to Robert Richter from AMD)
• Updated ARM Cortex A8/A9 support (thanks to Vince Weaver for his help on this)
• new MIPS 74k support contributed by Phil Mucci (SamaraTechnologies)

There was a major refresh of the libpfm4 user API to make is easier to use and extend in the future. We are nearing the release of version 1.0

We have updated support for most of the non x86-processors, incl. SPARC, ARM, Power

A libpfm4 git commit mailing has been created to allow users to tracks changes to the library.

There were some major API changes to libpfm4. It is now simpler with fewer calls while providing default unit masks and more robust sanity checks on event strings. All the source is available in the GIT tree. Man pages and online documentation have also been updated.

The libpfm4 source code is now available for download. The source is managed via GIT. A git tree has been setup. It is totally separate from the CVS repository for libpfm3 and pfmon.

No formal release of libpfm4 is available as of now.

To clone the GIT tree:

  $ git clone git://perfmon2.git.sourceforge.net/gitroot/perfmon2/libpfm4
  

Libpfm4 is a complete redesign of libpfm3, almost all the code has been rewritten from scratch. This new version offers much better flexibility and simplicity to express events. It is not backward compatible with libpfm3.x.

Libpfm4 currently does not offer perfmon2.x support. It is initially targeted for the perf_events interface which has been selected over perfmon2.x to be in the upstream kernel. Perf_events is available since Linux v2.6.31 but only on Intel and AMD X86 and IBM Power processors.

Libpfm4 source code will be uploaded shortly. It will be available as a separate package from libpfm3.x. It will use GIT instead of CVS for source control.

The documentation for libpfm4, in the form of man pages, is now available on this site. It provides the complete view of the new interface. It is recommended to start with the introduction man page: libpfm.
