Well Linux has always been highly anti FPU in kernel mode, and Xenomai 3 seems to drop the idea of doing anything in kernel mode if possible, so since all your real time code should be in user space anyhow, there should not be any FPU issues. There have also been interesting bugs to do with FPU in xenomai 2.x under certain corner cases that have been entertaining to track down, although I don't remember if any had to do with user space versus kernel space or not. -- Len Sorensen _______________________________________________ Xenomai mailing list [email protected] http://www.xenomai.org/mailman/listinfo/xenomai
