Hello,
I have released another version of the perfmon new code base packages.
There is no major updates in this version compared to 061127. This is
a convenience release so that people can use plain 2.6.19.
The perfmon2 kernel changes are:
- fix UP exit bug in system-wide mode where the active context
accounting was done incorrectly.
- MIPS update to correct register hardware addresses (Phil Mucci)
I have also released a new libpfm, libpfm-3.2-061204 with the
following changes:
- updated MIPS processor detection code
Also a new version of pfmon, pfmon-3.2-061204 with the following changes:
- fix various perfmon v2.0 compatibility bugs for IA-64
- fortify return values for read() (will Cohen)
Both libpfm and pfmon releases work with kernel-patch 061127 or 061204.
You can grab the new packages at our web site:

Enjoy,

Some of the ptrace functions (e.g. ptrace_may_attach in perfmon_syscall.c)
being used in the perfmon kernel patches will go away with the utrace patches:

At least for ptrace_may_attach that's not true in the lastest version
from Roland - in fact it's the last unconditional function in ptrace.c
in that version. I suggested to him to rename and move it in my review,
though.

Sorry. I meant the function ptrace_check_attach(). -Will
