Hi all,
in our lab we're relying on Xenomai 3.1 + RTnet in order to control our
robotic platforms, which are seen as a network of EtherCat slaves.
I'd like to know more about the implementation status of Xenomai (cobalt)
over Dovetail, which to my understanding will be the only way to use > 5.4
kernel versions.

We mostly use the Posix API (thread, mutex, condvar), timers, IDDP, XDDP,
shared memory, and RTnet.

Is Dovetail already feature-complete w.r.t. Ipipe?

Is RTnet available?

How to migrate from an Ipipe kernel .config to a Dovetail counterpart?

Thank you very much,
Arturo

Practically, yes. We are using it just like I-pipe since the 3.2 release 
of Xenomai.

Yes.

CONFIG_DOVETAIL=y - you can basically see this in our CI setups 
(including xenomai-images) that are even able to handle both variants 
(depending on the kernel version) with a single config.
