Mehnert96 and Stange96 both describe an environment to use Linux-drivers together with L3. Is something similar available to L4/Fiasco? If yes, where can the example implementations be found?
Unfortunately in German there is a paper that describes an environment to port the Linux SCSI driver to L4:
http://os.inf.tu-dresden.de/papers_ps/l4scsi.ps
The source may be found at our CVS server.
Does L4-Linux directly access hardware ports? If yes, is it possible to prevent this behavior, e.g. by inserting a new "virtual hardware layer"?
In DROPS there is a Resource Manager (RMGR) that should control all hardware resources needed by L4 tasks (physical memory, hardware interrupts, I/O-ports). Until now I/O ports are not implemented yet.
