Hi, I did not received too much feedbacks about Part I stability, but I went on= , so Part II is available for tests. It presents an mmx copy which doesn't give much performance increases but what I need now is testing for correctness. In particular I would see feedbacks about races inside dropping/undropping FPU mechanism. It would be better testing with PREEMPTION + FULL_PREEMPTION enabled (and maybe on SMP archs). Some minor styling issues have been fixed of the previous patch. http://users.gufi.org/~rookie/works/patches/mmxcopy.tar.gz This mmx copy is not intended to be in final release, this is just a testin= g issue in order to involve CPU < P4 & friends. For anything else, mail to me. Attilio -- Peace can only be achieved by understanding - A. Einstein
