This version of the kernel patch is relative to 2.6.17.1. The patch includes: - support for 32-bit mode AMD64 processors (Chuck Ebbert) - mini-argument buffers on stack optimization for read/write of PMU registers - fix user group permission checking which were ignored - fix a missing irqsave in perfmon_kapi.c For the stack buffers there are per-arch constants that can be adjusted based on stack size limitations. Look for PFM_ARCH_PM*_ARG. I have also release a new libpfm, libpfm-3.2-060621, which includes: - support for 32-bit mode AMD64 processors - fix an opcode matching/range restriction limitation for Itanium2 PMC13 and Montecito PMC41 registers. This version of the library works with 2.6.17-rc6 and 2.6.17.1 Also a new version of pfmon, pfmon-3.2-060621, to take advantage of the update in libpfm: - support for 32-bit mode AMD64 processors - updated event name parsing to prepare for separate event unit mask management (Kevin Corry) - fix the detection of unavailable PMC registers. it was causing crashes when used with sampling. Note that I have tested 32-bit compiled libpfm,pfmon running on an 64-bit AMD perfmon kernel. I have not tested on a 32-bit AMD linux kernel because I don't have such setup. I would appreciate any feedback on this. You can grab the new packages at our web site: http://perfmon2.sf.net PS: I will post an incremental kernel patch and a diffstat on the perfmon mailing list. -- -Stephane
