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 .

Hi Bjoern, thanks for the quick reply. I actually following the BID tutorial in a way to omit the L4 IPC syscall bindings and all :) looks like I don't have any choice here, do I? I'll appreciate it. Thanks though ;)
Lucille.

Hi,
I have been creating a package which implements a server invoked by a client. I understand from the tutorial that I have to create an IDL
file
listing all my public function there. Problem here is that, I would
like
to know whether I really need to do the IDL file or can there be other
way that I can actually skip the IDL and how do I do that, since my intention here is just to create a simple communication with purpose between my server and client using 1 same language, C. Please advice
me
in this.
Of course you can skip the IDL part completely. Have a look at the documentation of the L4 IPC syscall bindings (http://os.inf.tu-dresden.de/l4env/doc/html/l4sys-l4v2/index.html) and or at the L4v2 reference manual (http://i30www.ira.uka.de/research/documents/l4ka/Ln-86-21.pdf) to learn
about how to implement a server without IDL.
