Re: L4-Linux as a real-time OS

1) Is that kind of idea crazy?
Not at all!
2) Is there anyone who tried (or is going to try) something like that?
We often use setups similar to the one Frank described (external L4 task doing real-time work, L4Linux runs a timesharing load) for research purposes. I am not aware of anyone who used L4Linux clients for real-time work, but the idea is interesting. I see that L4Linux clients are easier to develop and debug. However, Frank recently finished an L4-task loader for L4Linux that regains some of Linux' convenience for L4 development.
3) Is L4-Linux going to keep up with the revisions of Linux in the future?
We certainly plan keeping L4Linux up-to-date, but I cannot make any promises. It's a matter of demand (both by ourselves and by others) and resources. Regards, Michael -- hohmuth@innocent.com, hohmuth@inf.tu-dresden.de http://home.pages.de/~hohmuth/
Hello, The same apology again for my 10 days too late reply.

I really understand what you mean.

I'm glad to hear you say so.

There is more to the reason of my persistence in doing "L4Linux clients for real-time work". My application, actually not my application but a rather complex application shared by lots of institutions for large scaled experimental physics, requires real-time tasks and non-real-time tasks to share the same address space. The application is named as Experimental Physics and Industrial Control Systems (EPICS). Please take a look at http://www.aps.anl.gov/epics/ if it could interest you.

I hope the "demand" increases more and more because I think L4Linux is attractive from the both points of views, OS and application. Jun-ichi
