Hi,
Here are my questions:
1. Which communication control mechanism is implemented in Fiasco? Is it "Clans and Chifs" as specified in "Lava Nucleus (LN) Reference Manual" or something else?
2. AFAIK Fiasco (at least in public repository) doesn't support SMP yet. But at the same time there was SMP/Fiasco project and work performed by Sven Schneider "Multiprocessor Support for the Fiasco Microkernel". Are there any plans or maybe approximate date when SMP support will be available? What about L4Env with SMP support?
Best Regards, Alexander Valitov

Hi,
- Which communication control mechanism is implemented in Fiasco? Is it
"Clans and Chifs" as specified in "Lava Nucleus (LN) Reference Manual" or something else?
Fiasco does not implement Clans&Chiefs. There is a communication control mechanism based on reference monitoring. An example implementation can be found in l4/pkg/ipcmon.

Yes, there are plans. The next Fiasco version provides SMP support, but has not been officially released yet. I can't give you an exact date on when this will happen, sorry. Somewhen before summer might be a substantial educated guess, but this is not an official statement.
