Hi, As suggested in the list for volounteers, I'm currently working on optimizing kernel copying functions. As first step, I ported DragonFlyBSD's FPU handling design, which includes:
- modifies to MD part of struct thread - modifies to npx device driver - a lot of modifies about kernel copying routines structure - misc You will find some informations in the tarball, that maybe you would integrate with: http://www.leidinger.net/FreeBSD/dfly_fpu.txt.bz2 This is just a first step for final implementation. Next (and last) step is adding optimized functions to new system and I would like to avoid ripping completely DragonFlyBSD codes here beacause I have other ideas. Now a lot of testing (and possible feeds) is needed (I successfull compiled and used kernel in 6.0 with SMP, PREEMPTION and FULL_PREEMPTION enabled). Attached there's patch for FreeBSD-6.0 Greetings, Attilio -- Peace can only be achieved by understanding - A. Einstein
