In looking at the rthal patch for the i386, it seems 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. > 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.

It works fine both on 2.4 and 2.6 and is a major leap forward. > Also, I have been reading about Adeos and rtai's adoption of this. See www.xenomai.org ; then ask remaining questions on the xenomai mailing lists.
