L4Linux stub drivers & L4 drivers

[Alexander Valitov]

Hi All,

I’m new to L4Fiasco and L4Linux.
I’ve managed to build and run L4Linux 2.6.28 using dope (thanks to this mail
list).
In the next step I would like to remove as much as possible hardware access
operations from L4Linux to L4 servers. By splitting L4Linux driver into two
parts, first one is the L4Linux stub driver which talks to second L4 server
part which in its turn has a deal with access to hardware. Any form of
multiplexing/demultiplexing of hardware between several L4Linux instances is
not required at this stage, only monopolistic access.
Actually, the ideal solution for me is where L4Linux doesn’t have direct
access to hardware at all.

I have some questions to community:
1.	Is it generally possible?
2.	What kind of native L4 or DDE drivers are available now? And what about
corresponding stub drivers for L4Linux?
3.	How should I configure L4Linux or maybe packages in /trunk/l4/pkg/ to
remove as much as possible hardware access operations from L4Linux to L4
servers? Are there any ready-to-use L4Linux "config" files for this purpose?

Thank you in advance.

Best Regards, Alexander Valitov
