Thanks. The patch does indeed resolve the problem. Now oprofile can
properly handle the JVMTI events and can also resolve samples in JITed
code to the associated Java methods. :-)

Hi, Volker,
Just checking on the status of this bug. Thanks.

Hi, all,
I've begun adding ppc64 support for the serviceability tools that take a java
core file as input (jmap, jstack). See my original July 3 posting to
ppc-aix-port-dev (subject "PowerPC: core file option not available with
serviceability tools") for reference. I've created a number of new

I hope you can help set me on the right track. As you can see, I'm lost in the
weeds right now. :-)

When Hotspot SA tools jmap, jstack, and jsadebugd are run against a core file,
they fail with the following runtime exception:
OS/CPU combination linux/ppc64 not yet supported
I will post a patch set that adds this support. The patch set consists of the
following patches:
PATCH 1/2: Upda
This patch updates some build files and C/C++ files to enable the PPC64
Serviceability
agent code in patch 2/2.

Going along with what appears to be tradition, the new PPC64 files have the
Oracle copyright statement instead of an IBM copyright, since much of the code
in
these files was copied over from the x86 versions.

I was just running the 'test' java app and, in another session, killing it with
SIGSEGV.
To be honest, I wasn&
