I put scheduler patches up on Freefall for review. They're in PATCHES.scheduler. Ignore everything in the posix1b directories and just look at the sys/kern and sys/{i386,alpha} changes. This doesn't directly address the recent alpha complaints yet, it is just a revisit to the scheduler to get back up to speed. I've also added "synch.9" to talk about what is in there. In particular look at hoisting userret into machine indepedent. I looked at 4.4Lite and I believe multiple arches can still be supported cleanly while moving a lot of this stuff into mi code, maybe at the cost of some per-arch "methods" passed in. Note that I've changed the kernel priority level on the Alpha of userret to splhigh - everything else is being done in the scheduler code at splhigh and that was pretty much the only difference between alpha and i386 (other than i386 previously being inline). Note - I nuked my new "sys/sys/synch.h" header when creating patches, so I quickly recreated it this morning and verified the kernel still builds. If you notice anything funky about the headers that is why. Peter -- Peter Dufault (dufault@hda.com) Realtime development, Machine control, HD Associates, Inc.
