rtai for ppc in 2.6
Hello,
A bit off topic, but I don't know where else to ask these questions.
I am working to port an existing Lite5200 application that uses rtai on the 2.4 kernel to a 2.6 kernel. I have just noticed that support for rtai in 2.6 is limited to the i386 tree. Is there anyone working on the ppc 2.6 rtai? In looking at the rthal patch for the i386, it seems non-trivial. Otherwise I guess it would be done by now. :-) Alternatively, I could rip out the rtai dependent code and just use the native 2.6 kernel's improvements for near realtime response and see how it goes but that route will take a little time. I was hoping for a quick recompile and go. :-( Any advice?
Also, I have been reading about Adeos and rtai's adoption of this. Does this implementation preserve the same rtai interface? It looks like it is in the same boat as the rthal for ppc 2.6. Please correct me if I am wrong.
Thanks,

No, no such woirk is going on. And probably never will. RTAI is dead on anything but x86. Actually it has never been completely ported to PPC - things like LXRT are simply not portable.

Yes. My advise is: use Xenomai. It works fine both on 2.4 and 2.6 and is a major leap forward.

See www.xenomai.org ; then ask remaining questions on the xenomai mailing lists.
