Hello,
is it possible to run LTTng together with Xenomai? Or is there any
other profiling software that works with Xenomai? Thanks.
Regards,
Bernhard

Xenomai supports LTT oldgen on x86 for now, over 2.6.9 IIRC, since it's
the latest kernel LTT did support.
For performance profiling, oprofile over a Xenomai-enabled kernel works.

I nearly forgot the most important: thanks to Jan, we do have a built-in
performance profiler in recent Adeos releases for x86, providing precise
timing information about a running kernel, which can be used to locate
high latency spots for instance.
The patches in the following directory should be applied incrementally
against an Adeos-patched kernel:

A ppc version is in preparation.
