Hello,
I have released another version of the perfmon new code base package.
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:

PS: I will post an incremental kernel patch and a diffstat on the perfmon
mailing list.
