John Baldwin	c6f6b7292b	- Rename the gd_cpuno member of struct globaldata to gd_cpuid. ... - Add a globaldata_register() prototype in the SMP case.	2001-01-24 10:24:49 +00:00
Jake Burkholder	a448b62ac9	Make intr_nesting_level per-process, rather than per-cpu. Setup ... interrupt threads to run with it always >= 1, so that malloc can detect M_WAITOK from "interrupt" context. This is also necessary in order to context switch from sched_ithd() directly.

Jake Burkholder	7586909279	Remove unused per-cpu variables inside_intr and ss_eflags.	2001-01-12 07:47:54 +00:00
Matt Jacob	25b53bb41f	Store in globaldata our CPU ID#. Provide a lock for panics - only one ... CPU can panic at a time. Obtained from:Andrew Gallatin <gallatin@cs.duke.edu>	2000-12-09 20:52:42 +00:00
John Baldwin	4b2c46fab1	Add the 'witness_spin_check' per-CPU variable.	2000-11-15 21:58:02 +00:00
Jason Evans	0384fff8c5	Major update to the way synchronization is done in the kernel. Highlights ... include: * Mutual exclusion is used instead of spl*(). See mutex(9). (Note: The alpha port is still in transition and currently uses both.) * Per-CPU idle processes. * Interrupts are run in their own separate kernel threads and can be preempted (i386 only).
