Ok bidirectional FiFo's would be nice, but how about
mmap extension??
UserLand opens the fifo and does mmap(rtf,1Mbyte...)
the fifo driver will allocate memory and map it to UserLand.
after this UserLand and KernelLand will use the FiFo to tell
each other what happend to the shared memory. Going this
way the communication channel will be fast, and easy to use.
(I allready did a first mmap() try, based on the
Oreilly kernel driver book examples)

This is true! Just read the code of rt_fifo. I agree that two-way fifos
would
make live much more easier.
