Hi Lucyantie,
you still can directly invoke the kernel using assembler. In this case
stick with the Fiasco ABI description. I cannot cite a manual here,
because the Fiasco ABI evolved rapidly from the L4 Version 2
specification (http://os.inf.tu-dresden.de/L4/l4refx86.ps.gz). The only
"documentation" that exists are the L4 IPC syscall bindings.

If you really want to use the Fiasco kernel without getting "infected"
by the user level sources, study the Fiasco source to see how the
registers have to be filled to initiate an IPC.

Greetings, Ron.

BTW: If you can spare a moment or two you could contribute the lessons
you learn into our public wiki at http://wiki.tudos.org .
