Has anyone made Valgrind work on a xenomai user-space application?
My attempts so far (with valgrind 2.4.0 and 3.1.0 from gentoo) has lead to:
--25174-- WARNING: unhandled syscall: 555
--25174-- Do not panic. You may be able to fix this easily.
--25174-- Read the file README_MISSING_SYSCALL_OR_IOCTL.
Xenomai: native skin or CONFIG_XENO_OPT_PERVASIVE disabled.
(modprobe xeno_native?)
The native skin *was* loaded (the program runs without valgrind). I
think this means that valgrind needs to have code added to handle the
xenomai system calls-- but I could find no mention of xenomai on
valgrind.org (including the release notes archives).
Thanks in advance!

Yes, I am afraid. And looking at README_MISSING_SYSCALL_OR_IOCTL, there
is a lot of code to add.
But there is a way to run your programs with valgrind: use Xenomai
discrete event simulator, configured with the --enable-atomic-core
flag.
