kleink 66c2794142 Add _BSD_SUSECONDS_T_ and _BSD_USECONDS_T_; do some space vs. tab formatting
cleanup

ross 9dcfc52387 Put in Jason's recommended fix for the null-curproc-in-pmap.old.c problem. 1997-11-17 00:11:22 +00:00
mjacob 479bc8877c Protect userland applications from the inline splraise function. 1997-11-10 18:23:50 +00:00
thorpej e22396f499 Clean up the messages displayed when either platform support is not
configured into the kernel, or when the platform is not supported.
Use the defopt'ed options, rather than NDEC_... and remove the needs-flag
hack that's existed for a while.

thorpej 4730a8cbec Bug fixes and cleanup from Chris Demetriou <cgd@pa.dec.com>:
- fix _C_LABEL so that it actually works.
- make __RENAME use _C_LABEL.
- fix __RENAME so that it expects an unquoted argument.
- fix __indr_reference and __warn_references so that they
  supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
  by the way it's used).

The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.
(A ; all by itself isn't a great idea.)  The __indr_reference
change was made for consistency.

ross 0ea4820367 --Add handcrafted stack frame directives to locore.s palcode vector
--entries / remove kernel entry from locore / reorganize vector entry
--code. Enables access to stack frames transitively w.r.t. palcode
--vectors, e.g. upward traceback works, inverting (possibly several)
--kernel vectors. Until now, all trackbacks ended at the first-reached
--instance of trap(), which was totally useless as there is no mystery
--to trap->panic->cpu_reboot

thorpej 665f7d1a6e Implement __RENAME() in <machine/cdefs.h> 1997-10-22 05:20:32 +00:00
mjacob c83fc3eeb6 Remove __VM_PMAP_HACK. 1997-10-14 15:29:50 +00:00
bouyer 6ab3092b11 Add byte-swapping functions (bswap16, bswap32, bswap64) to libkern.
Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses
bswap32). Contribution of assembly versions of these are welcome.
Add byte-swapping of ext2fs metadata for big-endian systems.
Tested on i386 and sparc.

mjacob 42c325e139 A minor barely acceptable hack to handle having a kernel boot on a system
with large amounts of memory and not spew. This doesn't really replace
fixing this problem better later, but it works for now. Basically, if memory
is greater than 128MB, start upping the sizes of some maps.
1997-09-23 23:23:23 +00:00
mjacob b23bbbb05c Redo the platform specific identification and initialization, making
it more explicit where platform specific functions (like machine check
handling) should go.

mjacob 03a798a3fd Add some defines for alpha interrupt types. 1997-09-20 19:02:34 +00:00
leo d4713d24c2 Implement the kernel part of pr-1891. This allows for a more flexible sized
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

thorpej cd69e27594 Prototype alpha_implver(), and fix a think-o in a previous commit. 1997-09-17 23:33:28 +00:00
thorpej 87c1a08481 Add stubs for the Alpha Byte/Word Extension (BWX) instructions, present
on EV56 and later processors that have the "amask BWX" bit clear.  These
instructions will be used to implement non-swizzle bus access functions
on newer systems, such as the new AlphaStation 500s with EV56 and 21172
PCI chipsets.

See "Alpha Architecture Handbook, Version 3", DEC order number EC-QD2KB-TE.
1997-09-16 23:09:10 +00:00
thorpej 0599db7897 - Define bits used in the "amask" instruction.
- Define processor family IDs returned by the "implver" instruction.
- Prototype alpha_amask().

thorpej 36f209b762 Split off PALcode functions into their own header file. 1997-09-06 01:23:52 +00:00
thorpej 6f4f08b8b2 Add a few more PALcode operations, as documented in pages (II-B) 2-1 through
(II-B) 2-33 of the Alpha AXP Architecture Reference Manual, Second Edition:

* rdps - Read Processor Status, needed by spl* functions.
* cflush - Cache Flush
* rdval - Read System Value
* wripir - Write Interprocessor Interrupt Request
* wrval - Write System Value

cflush, rdval, wripir, and wrval are used in multi-processor environments.

thorpej 032358ab33 From hp300 pmap: use mycroft's pv_entry allocator (from i386 port). 1997-09-03 19:07:32 +00:00
thorpej f03ded039c Update from hp300 pmap: define an active_user_pmap() macro and use it. 1997-09-03 00:58:13 +00:00
thorpej 6cf58542f9 PMAP_{,DE}ACTIVATE() are no longer exported from the Utah-derived pmap. 1997-09-02 23:52:55 +00:00
thorpej b2a8424bb5 Garbage-collect loadustp(); the functionality has moved to pmap.old.c 1997-09-02 19:07:22 +00:00
thorpej 2c5c631b71 - Make the pmap_activate() and pmap_deactivate() interfaces consistent my
passing them a proc *, which encapsulates all of the information necessary
  to activate an address space.
- Garbage-collect pmap->pm_stchanged; it's not really used for anything.

thorpej b7b3955ce0 Fix a typo: ALPHA_PTE_WRITE needs to include the "user write" bit. 1997-09-02 14:29:37 +00:00
thorpej d95ac139e0 Oops, wrap cpu_decl()s inside #ifdef _KERNEL/#endif. 1997-09-02 14:25:34 +00:00
thorpej 8b6e894364 Clean this up a bit; defopt has rendered the #undef hacks unnecessary.
Also, put the cpu_decl()s in cpuconf.h, so that platform support files
can pull in the prototypes from there, and pull in options for those
systems for which there is code in the source tree.

thorpej e79009b830 Ressurect from the Attic. 1997-09-02 14:00:11 +00:00
thorpej 693b3e7262 Nuke the idea of <machine/options.h>. It completely defeats the purpose
of fine-grain option dependencies.

thorpej 3220411801 Define PAL_cflush, PAL_ipir, and PAL_OSF1_wrperfmon PALcode operations. 1997-08-29 23:17:37 +00:00
cgd bf596ddb89 don't define __BUS_SPACE_COMPAT_OLDDEFS if it's already been defined 1997-08-13 02:53:03 +00:00
cgd 2d184c2262 clean up bootinfo v1 struct a bit: add a hwrpb size field (in a backward-
compatible way), and clean up the comments to make things a bit clearer.
1997-08-11 23:43:38 +00:00
cgd bd3cab1531 fix comment glitch in the last change 1997-07-25 07:01:42 +00:00
cgd 395f4bac6b clean up bootinfo structure comments so they're more readable (to me,
at least 8-).  Add structure offssets for structure members, so we
know how much space we're using.  Make the version in the bootinfo
structure be a u_long, so there's no implicit padding in the structure.
Add a few more pointers to the bootinfo v1 structure, which will all
be set to NULL for now.
1997-07-25 06:59:47 +00:00
thorpej f56c3c315f More DDB support:
- Add support for software single-stepping (Alpha does not have hardware
  support for single-stepping)
- Alpha uses Elf64 symbols.
1997-07-25 00:06:25 +00:00
thorpej 08d4c7e688 Update alpha_init() prototype; takes two more args. 1997-07-25 00:04:36 +00:00
thorpej 264f1c5acc Define the bootinfo magic number and bootinfo (version 1) structure. 1997-07-25 00:03:47 +00:00
cgd 28b1691f4d when i was documenting the bus_space interfaces (the document
was sent to developers, but will eventually become a man page or
something), i noticed a few in various names:
(1) _map and _alloc should take a flags argument, rather than a
    'cacheable' boolean.
(2) BUS_BARRIER_* flags should be BUS_SPACE_BARRIER_*.
(3) bus_space_copy_* should be bus_space_copy_region_* for consistency
    with other region ops.
Fix all of these (in a backward-compatible way, at least for now).  Redefine
internal usees of those names to use the new names.  Also, while at it,
clean up the copy functions (remove unnecessary variables) and make sure
that they and other functions conform to the spec.

thorpej 7a8a1f3f1a Turn the extern declaration of __flt_rounds() into a proper prototype. 1997-07-17 21:36:03 +00:00
cgd fce829ca4b mark prototypes for static inline functions as possibly unused
(with __attribute__ ((unused))), to avoid generating warnings when
compiling without optimization but with the default warning flags.

mrg dc6a98e92c bring mrg-vm-swap2 onto mainilne. 1997-06-12 15:09:23 +00:00
thorpej 78cd3ba57f bus_dmamap_t's always have a pointer to an sgmap cookie. (oops, forgot
to commit this to the branch!)

thorpej 11e78a6b0d Pull thorpej-bus-dma branch into mainline. 1997-06-06 23:43:45 +00:00
cgd 891e8db771 two more slight bogons 1997-06-05 17:36:26 +00:00
cgd 1c33c6bff8 actually, declare _splraise() as an inline function, because:
(1) it was using 'max', and some functions use a variable
	    of that name (*sigh*), and
	(2) that makes it easier to be a bit trickier, and only call
	    swpipl if changing the IPL.

cgd 100dbb8a3c parens around macro arg (this is an old one) 1997-06-05 17:20:17 +00:00
cgd 57c012e265 make sure that splnet(), splbio(), splimp(), spltty(), splclock(),
splstatclock(), and splhigh() all _raise_ the IPL.  (splhigh() is _not_
the highest possible IPL; mcheck is...)
