Hello,
I'm interested in Sawmill, but could not find any place to download it and the e-mail address on the web site does not work. Does anyone know if the project still exists and if so, wether there is a Sawmill mailing list and/or download page somewhere.
I'm new to L4 and would like to learn more about microkernels by playing around a bit with the various versions. But it looks like that, except for the L4 kernels, there is not much to play with. Or is there?
Groetjes, Peter Busser

Well, there are several websites to look at:
http://os.inf.tu-dresden.de/l4env/ http://os.inf.tu-dresden.de/drops/ http://os.inf.tu-dresden.de/L4/ http://os.inf.tu-dresden.de/fiasco/

I don't know what you're looking for but these sites should give you a start. You can definitely find L4 user-level programs there... ;)

I've seen those. I was looking for a bit more Linux compatibility for the time being, so I don't have to give up my current environment alltogether. Maybe I have missed something, but to me it looks like only L4Linux and Sawmill provide such an environment.

Well, AFAIK sawmill was a project which never left it's highly experimental stage, so it's nothing you want to use (besides getting it actually). But I've never seen it myself so I may tell nonsense.
L4Linux-2.2 is quite stable by now but has more and more problems with recent hardware (no surprise).
To play around with L4, use Fiasco/UX. You don't need a extra machine or similar, just run it on your shell. You can't really do driver development there, of course. But for real user level stuff it's nice.

SawMill was a joint research project between IBM research and (at least) University of Karlsruhe. The sources have never been publicly released. Karlsruhe (and also Dresden) use many ideas, concepts, and outcomes of SawMill in current projects, such as the dataspace manager concept, integration of device drivers, etc. Furthermore, the V4 API design and IDL4 were extremely influenced by SawMill.
