Hey Erwin,
the linux kernel is just the lowwest priority task under RT-linux.
Everything you
run on normal Linux is not realtime. The RT-module could just pass the
information
via the RT-FIFO's to "normal" Linux and than yer display application can
read them
and do whith them wat it wants.
take a look at the docs on www.rtlinux.org and to the examples even
though not all
very uptodate they give a iddea how it all works.
