I'm also interested in that, I may add. I was -- already some months
ago; then I had to interrupt because of more stringent issues taking over
-- thinking about attempting such a project, starting with reading papers
about (a proposal for?) L4's way of handling hardware interrupts in user
space servers. <http://os.inf.tu-dresden.de/~hohmuth/prj/omega0.ps.gz>
-- ``Omega0 -- a portable interface to interrupt hardware for L4
systems.'' by J. Löser and M. Hohmuth.
Can any of the L4-savvy people (Marcus?, Neal?) comment on this? Is this
feasible for Mach as well? Is this what L4 is still using? I can see
code for this in the TU Dresden L4 repository, so i guess they're
actually actively using this proposed interface?
What is Minix doing? Or other microkernel-based systems?

Thomas
