Alec,
I do realize the kernel is modified as part of Cobalt installation. This
is certainly why only specific kernels are supported. Which is why I was
looking for a distribution which shipped with a supported kernel.
I was neither expecting nor looking to distrowatch for a distribution
which included Cobalt. All I was looking to distriwatch for was a
distribution which shipped with a kernel version supported by Cobalt. I
found none, which is why I went to the community.
In the absence of any such distribution that ships with a supported
kernel, I will fall back to selecting a distribution whose kernel can
easily be updated to a Cobalt supported kernel version. At the moment,
Ubuntu seems a very likely source. If you would suggest a specific
distribution and version I would be most appreciative.
Thank you for your assistance.

Hi,
Cobalt enabled vs cobalt supported, what is the difference here? Cobalt is part
of Xenomai, you patch the kernel using prepare-kernel.sh and you enable the
Cobalt kernel config option via Kconfig menu. If you want to write an RTDM
driver, the kernel must be patched and configured appropriately.
The Xenomai/Cobalt stuff is all distro-independent, ipipe and all is kernel
space. You won't find anything about Cobalt on distrowatch.
I didn't insult you, I said that if you're looking for a distribution with a
Xenomai kernel shipped with it because building from scratch is too big a task,
you're better off avoiding writing a driver.
If you're serious about doing this, just build the kernel yourself and work on
your driver with whatever distro you want. Some distros/desktop environments
offer lower latency than others by the time you're all done, but that's really
about it. LXDE/LXQt might give you better scores than let's say GNOME/KDE.
Does this answer your question? If not, let me know what I'm missing as I'm
doing my best to help.
Alec
