E-mail: eranian@hpl.hp.com X-HPL-MailScanner: Found to be clean X-HPL-MailScanner-From: eranian@hpl.hp.com Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hello, I have released another version of the perfmon new code base package. This version of the kernel patch is relative to 2.6.20. This new kernel patch includes the following new features and bug fixes: - first cut at supporting Oprofile on i386 and x86-64 architectures - several internal interfaces simplfications - various MIPS updates (Phil Mucci/Manoj Ekbote) - varous PPC32 updates (Phil Mucci) - fix bug in set switching with a single set - fix bug in pfm_restart() for per-thread mode with blocking notification Unfortunately, this release does not build for PowerPC due to a problem with the TIF_* flags. Perfmon adds 2 new flags which make the TIF now use more than 16 bits which causes problem with some assembly instructions in entry_64.S. Hopefully, this will be fixed in the next release. To make Oprofile work, you need a modified user level Oprofile package. I have made a first pass at modifying 0.9.2 to work on Perfmon 2.3 (and v2.0 for IA-64) for the following processors: AMD Opteron, P6, Core Duo, Core 2 Duo, P4. The modified package is available as Alpha at: ftp://ftp.hpl.hp.com/pub/linux-ia64/oprof-perfmon2-070122.diff I have also released a new libpfm, libpfm-3.2-070206, with lots of changes. Here are some of the most important ones: - Full Intel Core 2 Duo event table (Thanks to Dan Terpstra for his help) - Full event table for P6 and Pentium M (Dan Terpstra) - various MIPS updates (Phil Mucci) - improved Montecito event->counter assignment routine - rewritten P6 event->counter assignment routine - extended detect_unavail_pmcs() code to handle pmds - extended whichpmu.c example to show implement vs. available registers - possiblity to force a libpfm PMU different from host PMU - several bug fixes to library and examples Also a new version of pfmon, pfmon-3.2-070206, with a few changes: - rewritten the automatic sampling buffer sizing based on the resource limits (rlimits) and perfmon global settings - Intel Core 2 Duo event listing now shows if event supports PEBS - fixed important memory leak that showed up when monitoring across fork/pthread You can get the packages and more detailed changelogs our the web site: http://perfmon2.sf.net (go to Project Files) Enjoy, PS: home page not yet updated due to a problem connecting via ssh to SF.net today. -- -Stephane From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stephane Eranian Date: Tue, 13 Feb 2007 18:48:39 +0000 Subject: 2.6.20 new perfmon code base + libpfm + pfmon Message-Id: <20070213184839.GC10031@frankl.hpl.hp.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: perfmon@napali.hpl.hp.com Cc: linux-ia64@vger.kernel.org, linux-kernel@vger.kernel.org, oprofile-list@lists.sourceforge.net, eranian@hpl.hp.com, perfctr-devel@lists.sourceforge.net Hello, I have released another version of the perfmon new code base package.
