Hello,
I am asking for an already answered question from a very long time ago.
How can I use valgrind with Xenomai ?
Here (https://mail.gna.org/public/xenomai-help/2006-03/msg00072.html) Gilles C. tells us to use --enable-atomic-core
But I can't find this option. Maybe it has been renamed ?

Ok, so is there something that can replace Valgrind and works with Xenomai ?
I am using the VxWorks skin.

You can use valgrind either with Xenomai simulator, but that will not be
easy, or with Xenomai-solo. But not with the dual-kernel version.

Could you comment on the status of Xenomai-solo? Last time I checked
(some 7 months ago) it was missing parts of the native skin. I also
remember the git checkout was not compilable. I'm rather interested in
using it for (automated) testing purposes, such as memory leak checking.

Xenomai-solo was proof of concept work, which eventually moved to the
xenomai-forge repository where the next Xenomai 3 architecture is being
developed. The development of the native API in the -solo branch is
discontinued, it will resume in another form in the -forge repo at some
point.
There is no documentation about the -forge contents yet. The survival
kit when browsing this code includes knowing that:
- it aims at providing support for both dual kernel based and
native-linux (typically PREEMPT_RT) platforms, using the largest
possible base of common code.
- most of the high level API implementation started to move to userland,
with no more API-specific kernel code. These APIs get real-time services
from the POSIX layer available with the underlying environment (dual
kernel's POSIX skin or nptl from native linux), which specifics are
hidden by an abstract service library.
- "copperplate" identifies the library which abstracts the real-time
services used by the high level APIs, so that their implementation is
not dependent on the underlying real-time core. It is a bit like the
nucleus API, but for userland client usage.
- this new architecture therefore exhibits two real-time cores, selected
at build time. The dual kernel core inherited from the Xenomai 2
architecture is nicknamed "cobalt" in the sources. The native linux core
inherited from the -solo work is called "mercury".
- the whole thing is still in flux.
