I'm sorry, but I'm still confused about the 'RT' terminology. Do you
mean the old RT-Linux, or the new PREEMPT_RT?
In the new preempt-rt, everything runs in user space, including rtapi,
which has been the focus of my investigation. There was an earlier
email that linked a page explaining 'priority inversion', which
preempt-rt addresses as the major part of running real-time processes in
user space.
As for the original RT-Linux, I know very little about it.
Did I understand (and answer) your question well?
John
