Hi Andre,

maybe they do not contain a plug-in solution to your problems, but I
wrote a couple of papers on real-time scheduling on top of L4
microkernels which could be useful as a starting point:

http://ertos.nicta.com.au/publications/papers/Ruocco_RTSS_06.abstract
http://www.hindawi.com/journals/es/2008/234710.abs.html

Please note that the journal paper discusses real-time scheduling on
general-purpouse L4 microkernels, specifically L4 Pistachio v0.4, and a
*now*-*obsolete* version of L4-embedded. The recent OKL4 v3.0 addressed
all the real-time scheduling issues discussed in the paper.

Comments and criticism on the papers are welcome!

	Sergio

Your manuscript is both good and original; but the part that is good is
not original, and the part that is original is not good.
