if it's possible from a kernel RT context, it's a plus
You may use XDDP IPC for that, see:

well thank you, that fits the bill exactly!
in case I would want to use the same method with kernel RT as long as
that lives, I take from the below post I would have to use the native
rt_pipe API to talk to the userland counterpart (the latter unchanged
I assume)?

You should be able to use the RTDM API in kernel-space. Provided that
you use the "rt_dev" prefix.
