40339b39f9 Reduce use of curproc in several places:
- Change ktrace interface to pass in the current process, rather than
p->p_tracep, since the various ktr* function need curproc anyway.

 - Add curproc as a parameter to mi_switch() since all callers had it
handy anyway.

 - Add a second proc argument for inferior() since callers all had
curproc handy.

Also, miscellaneous cleanups in ktrace:

 - ktrace now always uses file-based, rather than vnode-based I/O
(simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD.
Do non-blocking I/O, and yield a finite number of times when receiving
EWOULDBLOCK before giving up.

 - move code duplicated between sys_fktrace and sys_ktrace into ktrace_common.

 - simplify interface to ktrwrite()

a7d0570e67 First sweep at scheduler state cleanup. Collect MI scheduler
state into global and per-CPU scheduler state:

	- Global state: sched_qs (run queues), sched_whichqs (bitmap
	  of non-empty run queues), sched_slpque (sleep queues).
	  NOTE: These may collectively move into a struct schedstate
	  at some point in the future.

	- Per-CPU state, struct schedstate_percpu: spc_runtime
	  (time process on this CPU started running), spc_flags
	  (replaces struct proc's p_schedflags), and
	  spc_curpriority (usrpri of processes on this CPU).

	- Every platform must now supply a struct cpu_info and
	  a curcpu() macro.  Simplify existing cpu_info declarations
	  where appropriate.

	- All references to per-CPU scheduler state now made through
	  curcpu().  NOTE: this will likely be adjusted in the future
	  after further changes to struct proc are made.

Tested on i386 and Alpha.  Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.

8e44b27348 Rename the machine-specific stack trace printing functions
from db_stack_trace_cmd() to db_stack_trace_print(),
and add an additional argument, a function pointer for an
output routine (i.e. printf() or db_printf()).

Add db_stack_trace_cmd() in db_command.[ch], calling
db_stack_trace_print() with db_printf() as the printer.

Move count==-1 special handling from db_stack_trace_print() [nee
db_stack_trace_cmd()] to db_stack_trace_cmd() [nascent here].

Again, I'm unable to test compilation on all affected platforms,
so advance apologies for potential brokenness.

8964c35eca Introduce a new process state distinct from SRUN called SONPROC
which indicates that the process is actually running on a
processor.  Test against SONPROC as appropriate rather than
combinations of SRUN and curproc.  Update all context switch code
to properly set SONPROC when the process becomes the current
process on the CPU.

f3528d725d Interface change: db_printsym() takes a third argument, pr, a function
pointer indicating how to print the symbol. This allows db_printsym()
to called in places where db_printf() is not an appropriate output
function.

While straightforward, apologies in advance if I've introduced any minor
syntax errors; I was unable to test compilation this on all the affected
platforms.

07a3d660c5 This change courtesy of Charles Hannum <root@ihack.net>. This
addresses the problems seen by Jason Thorpe <thorpej@netbsd.org> and
Erik Berls <cyber@netbsd.org> necessitating rev 1.20 of
biosboot/main.c.

Move BOOTSEG from 0x100 to 0x1000.
Move heap from 0x10000 to 0x20000.

XXXXXXXX

This is a Kluge From Hell to allow boot blocks to grow a little larger
without diskbuf[] crossing a 64k boundary.

it to determine the boot device: mvme68k, pc532, macppc, ofppc.  Those

aa0007b5a5 In case of db_onpanic=0, still drop to ddb if the trap was from within

i.e. "db> x/s 0x14" should return you to ddb when it faults, regardless
of the state of db_onpanic.

a2606dbe80 Address PR#10042: instead of getting the dynamic configuration
all the time (which crashes some vaios), get the static configuration,
and if config_search() finds a node, then do the dynamic configuration.
This seems to work fine on multiple vaios (which seem to crash
in different places...go figure).

Also, bring prototypes in-line with KNF and declare static as appropriate.

"#if 0" out pnpbios_getapmtable() and pnpbios_setnode() as they
are not called.

Fix printf()s to print out dv_xname.

Fix a comment typo.

Use manifest constants (PNP_CF_DEVCONF_DYNAMIC, etc.) in calls to
pnpbios_getnode() instead of hardcoded constants.
