Hi, this is the last release which is rather finished and complete for the project. I tested for consistency for a long time and the FPU handling mechanism seems very robust so as copyin/copyout do. What I'm looking for, at this point, are testers for peroformances. What is proposed in the patch is one of the better solutions for UP archs (not running with PREEMPTION) but more general cases might be handled with time. I hope that somebody wants to play with him, giving suggestions and doing different benchmarks. The code can be found here: http://users.gufi.org/~rookie/works/patches/xmmcopy_6_1.diff and is for RELEASE_6_1 in order to have a wider range of testers (a diff against HEAD will be available ASAP). Please keep in mind that this is not a complete rip of DflyBSD code beacause it is different in a lot of parts. For any kind of tecnical questions, please mail me. Attilio PS: a particular thanks goes to Bruce Evans for his benchmarks and feedbacks about code structure -- Peace can only be achieved by understanding - A. Einstein
