Andrew Gallatin 386eac30d9 Improved support for alpha SMP. The following commit gets dual AS2100s ... and AS4100s into single user mode. This work was done jointly by jhb and myself, and builds on dfr's earlier work. smp_init_secondary() / smp_start_secondary() - use the uniq val to pass the globalp (me) - fancy footwork to take any pending machine checks (me) - doing things the FreeBSD way and getting the per-cpu idleproc created correctly, and synchronizing the startup of secondaries (jhb) mp_start() - better recognition of available cpus (jhb) smp_rendezvous() - if smp hasn't started, only run the rendezvous function on the current cpu. Sleuthing and (prior) incorrect fix by me, correct fix by jhb smp_handle_ipi() - more verbose handling of console messages (jhb) - grab sched lock around setting PS_ASTPENDING (jhb) forward_*clock() - commented out. Joint decision by dfr, jhb and myself General synchronization improvements (more mb()s, etc) (jhb) Printf cleanups (joint) Whitespace cleanups (jhb)		2001-04-17 14:55:09 +00:00
