You could write a known msg into the ring buffer from the RT thread,

Nope. the poster is looking for a way to notify a different thread that it
would be worth checking out the contents of a ringbuffer.
There are only two ways to do this: either wake the other thread regularly
based on a timer, and hope that the chosen interval and accuracy are enough
to keep the buffer (empty|full) OR wake the other thread as needed. this
second option requires some sort of communication channel to the thread to
wake it, which could be (on linux) any of a pthread_condvar, a semaphore, a
FIFO/pipe, and eventfd, etc. etc.
