- We now have enough per-cpu idle context, the real idle loop has been revived (cpu's halt now with nothing to do). - Some preliminary support for running some operations outside the global lock (eg: zeroing "free but not yet zeroed pages") is present but appears to cause problems. Off by default. - the smp_active sysctl now behaves differently. It's merely a 'true/false' option. Setting smp_active to zero causes the AP's to halt in the idle loop and stop scheduling processes. - bootstrap is a lot safer. Instead of sharing a statically compiled in stack a number of times (which has caused lots of problems) and then abandoning it, we use the idle context to boot the AP's directly. This should help >2 cpu support since the bootlock stuff was in doubt. - print physical apic id in traps.. helps identify private pages getting out of sync. (You don't want to know how much hair I tore out with this!) More cleanup to follow, this is more of a checkpoint than a 'finished' thing. |
