Thanks a lot Adam! I'll think about which road to take during Christmas. Nice holidays,

Did anybody try this? Something like this is in 2.4. I do not think this is particularly hard. The concepts are the same. One needs to get some memory from somewhere, start tasks somewhere, etc. I don't see big obstacles. > >> e) If Fiasco would be running on PowerPC, would it be possible > >> to run L4Linux without changes? > > If one wants to have binary compatibility then some PPC code needs > > to be there.

Is that still the case? I'd rather they that it's adapted to run in user-level, using L4. Some of the instructions cannot be executes on user-level, they're replaced, or removed, or whatever. > And so far only the IA32 part of Linux is changed that way, isn't it?

Basically yes but all the architecture independant code is already there, and two example architectures.
