ross 19a4c3110c Rip out 70 lines of (all of) the port-alpha-specific decls and prototypes.
They should not be visible to the MI kernel and the MI kernel shouldn't
depend on this junk.  Most of it moves to new module <machine/alpha.h>.

Leave badaddr() here, though, because it's used so widely.

thorpej 49c62c4336 Changes to support fork_kthread():
- cpu_set_kpc() now takes void *arg third argument, passed to the
  entry point.
- cpu_fork() allows parent to be non-curproc iff parent is proc0.
  When forking non-curproc, assume its state has already been saved.
- Adjust various pieces of machine-dependent code to account of all of this.

thorpej b38544d99e Oops, back out a buglet I didn't intend to commit in the last change. 1998-10-07 18:29:26 +00:00
thorpej d681cf055a configure() prototype is in <sys/device.h> 1998-10-06 20:50:15 +00:00
thorpej 69d81d8df1 Prototype cpu_halt_secondary(). 1998-09-29 07:07:36 +00:00
thorpej fcb0203141 First-cut at code to spin up secondary processors on a multiprocessor
Alpha system, conditional on MULTIPROCESSOR.

NOTE: This does not yet work completely.  The secondary CPU begins the
boot process, but never makes it into the cpu spinup trampoline.  This
is merely a snapshot of a work-in-progress.

ross d58ad29b6c Kill the old extern mchkinfo pointer and prototype cpu_mchkinfo().
This file has been collecting prototypes and other things used in the MD
code...that's bad...because this is exported to the MI kernel.

mjacob 6b092524ea stale beer- place structure in right file 1998-07-08 17:20:42 +00:00
mjacob 35ffe8edb3 Add machine check type definitions. Structure the expected/received
machine check items.

thorpej b4e77b173a Add support for non-contiguous physical memory, using MACHINE_NEW_NONCONTIG.
These changes also recover memory that is located before the kernel in
the first system software segment on systems which do not use the PROM
for console I/O.  Written by Chris Demetriou and myself.

cgd 25d056473c Clean up kernel initialization. Use the bootinfo structure (or innate
knowledge) earlier, and gather all information needed earlier.  Mark the
init code carefully re: when it can print stuff out, when it can expect
the firmware to stop working, etc.  Be more careful about using the PROM
console and other PROM facilities, and hint that in the future all use
of firmware/boot program callbacks by the kernel should go away (since
the world may not be mapped the way the firmware/boot program wants!).
1998-02-13 02:09:03 +00:00
cgd 92d17b5b50 clean up the way bootinfo information is passed and used: move the version
number passed by the boot block into a register, change the kernel's
bootinfo handing so that it always uses bootinfo to get bootinfo-ish values
(filling them in if the boot blocks didn't pass them), and make versioning
a small bit more sane.

mjacob b23bbbb05c Redo the platform specific identification and initialization, making
it more explicit where platform specific functions (like machine check
handling) should go.

thorpej 08d4c7e688 Update alpha_init() prototype; takes two more args. 1997-07-25 00:04:36 +00:00
cgd 562fa9b97d clean up NetBSD RCS ID strings 1997-04-06 08:39:37 +00:00
cgd e48fd73808 astpending and want_resched are kernel-only 1997-01-24 06:38:37 +00:00
cgd 1a8f25c523 add a "machdep.booted_kernel" sysctl, which is the name of the booted
kernel as supplied by the SRM console's BOOTED_FILE variable.

cgd 6c9cb4aa9b compile cleanly with:
-Werror -Wall -Wstrict-prototypes -Wmissing-prototypes -Wcast-qual

cgd 5beb1a522c (1) Add unaligned access fixup code to fix unaligned quad, long,
and IEEE S and T floating datum loads and stores.  VAX floating data
types not yet supported, and in the future will only be supported if
FIX_UNALIGNED_VAX_FP is defined.  (No point in wasting the space when
most of the time there will never be VAX FP loads and stores.)  Right
now, these features can be controlled only by sysctl.  The (boolean)
integer sysctls machdep.unaligned_print, machdep.unaligned_fix, and
machdep.unaligned_sigbus control printing about unaligned accesses
(defaults on), fixing up of unaligned accesses (defaults on), and
forcing a SIGBUS on unaligned accesses (defaults off).  If an access
is not fixed up (for lack of method or explicit decision), a SIGBUS is
always generated to keep programs from using bogus data.  At some point,
these three choices should be controlled by per-process flags, as well.

cgd 105697388d Instead of treating the trap/syscall/exception frame like a struct
containing a substruct (the hardware frame) and an array of registers,
treat it like one big array of registers, for easier and prettier
access.  Update everything to deal with that.

cgd 4d024971bf update to use new definitions in alpha_cpu.h 1996-07-11 03:46:00 +00:00
cgd 04294813bd various cleanup, move setsoft* and spl* into intr.h. 1996-07-09 00:33:20 +00:00
cgd 1beca2d96b add a new machine-dependent sysctl, machdep.root_device, which is the
(string) name of the root device.  It's a string so that it can
be used before dev_mkdb has been run.

mycroft ce000f04ef Remove deprecated cpu_setstack(). 1995-12-21 05:01:32 +00:00
cgd c83f9c5568 remove unused cpu_exec() definitions. moved "broken swap" markers, for
ports that still need it, to types.h.

cgd ba164ee03d update for various (old) NetBSD changes 1995-06-28 01:16:13 +00:00
cgd 8703076975 define BROKEN_SWAP and/or cpu_swapout as appropriate. 1995-05-05 03:41:51 +00:00
christos de42a28a1b - added sunos_machdep.c for sun3, atari, amiga and mac68k.
- changed machdep.c and trap.c to use struct emul.
- remove ep_setup references.
- added struct emul to all emulations.

cgd 804b49ae1f remove support for double-mapping the user area/kernel stack 1995-03-24 15:01:31 +00:00
cgd 85854cb4ad preliminary Alpha support. note that NOT ALL OF THE MODIFICATIONS TO
THE REST OF THE KERNEL ARE IN THE TREE YET.  Also, some of this is
_incredibly_ hack-ish, etc., but it works.
