I think that means no RTAI patch for ARM? Have you seen this project, which is similar to what I'm doing? http://www.bitmuster.org/projects/emc.html http://gitorious.org/emc-rt-preempt This effort seems to have stalled, and the patch applies to v2.4.4. However, it compiled easily using the cookbook in the first link. Maybe it would get you to where you could run those performance tests. That project was where I initially started from, but there were some messy things in the patch that I didn't feel like cleaning up, so I went back to Michael Buesch's original, very clean patches. (The mess was nothing that would stop you from compiling the project, but things like ripped out .gitignore files, a committed .rej file, other stuff. At some point I may go back to check for any useful additions, but I'll leave out the SHM bit.) Anyway, good news is Michael's patches forward-ported to git HEAD compiled last night with minor twiddling. I'll be running tests over the next few days to see if the beast actually runs. ;) John ------------------------------------------------------------------------------ For Developers, A Lot Can Happen In A Second.
