Hi,
I have no experience with Xenomai and I was wondering if someone could
clarify if cyclictest is included in Xenomai 3.1?
Here [1] says "cyclictest is part of the Xenomai test suite..." but I could
not confirm it.
If I simply install the rt-tests package and run cyclictest will it take
advantage of the cobalt "kernel" by default or do I need to preform some
extra steps (activate a posix skin etc)
Thank you

AFAIK cyclictest uses the POSIX skin.
The Xenomai version is based on rt-tests 0.92 (current version is 2.1).
I do prefer using "latency" for Xenomai.

When you say

Do you mean that there is an embedded cyclictest?
I could not find any trace of cyclictest. I had to install it using apt and
the rt-tests package.
I see a huge difference when executing cyclictest after booting with the
xenomai kernel vs the vanilla but how can I be sure that it is using cobalt?

Cyclictest is included in the rt-tests package.
https://git.kernel.org/pub/scm/utils/rt-tests/rt-tests.git/
rt-tests is provided with Buildroot or Yocto (well known build systems for
embedded Linux).

Xenomai carries a slight adjusted but likely significantly outdated
version of cyclictest in-tree [2], primarily for demonstration purposes.
The "official" test is called "latency" [3], and that one is also part
of our regular testsuite.
