ragge 825165a54a Octal numbers _must_ have a heading '0'! 2001-05-15 18:59:45 +00:00
ragge 5d8483d12a KA690 is not a Mariah. From Michael Kukat. 2001-05-02 17:35:12 +00:00

matt 1e70afa5e6 Make the jmp_buf bigger under ELF so it can store a full context. 2001-05-01 04:47:37 +00:00
thorpej cf67ac7122 Per discussion w/ chuck and chuck, restructure the md page stuff 
to use a structure called "vm_page_md", and use __HAVE_VM_PAGE_MD
and __HAVE_PMAP_PHYSSEG.
 2001-05-01 02:19:13 +00:00
thorpej 2b27ac7a99 Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for 
each vm_page structure.  Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM.  These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg.  As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now).  Changes to other pmap
modules will follow.

kleink fe3c9ceaf7 * Move definitions of exact-width integer types from <machine/types.h> 
to <sys/types.h> and <sys/stdint.h>.
* Add a new C99 <stdint.h> header, which provides integer types of
  explicit width, related limits and integer constant macros.
* Extend <inttypes.h> to provide <stdint.h> definitions and format
  macros for printf() and scanf().
* Add C99 strtoimax() and strtoumax() functions.
* Use the latter within scanf().
* Add C99 %j, %t and %z printf()/scanf() conversions for
  intmax_t, pointer-type and size_t arguments.

kleink 99054d7a6c Add definitions for C99 fastest minimum-width integer types. 2001-04-26 16:25:19 +00:00
ragge 2f019a2701 Support for KA681 (4000/500A) from Michael Kukat. 2001-04-24 20:16:36 +00:00
thorpej 69abdbf60c Undo a misguided previous change to the pmap_update() API. 2001-04-22 23:19:26 +00:00
thorpej 4738622712 Give pmap_update() an argument (a pmap_t) so that it knows which 
pmap it should be updating.
 2001-04-22 00:33:59 +00:00
thorpej 15f731ee94 pmap_update() should not be equated with "flush entire TLB", it is 
used to process deferred pmap operations.  Since these pmaps don't
defer anything, pmap_update() is a noop.
 2001-04-21 17:25:01 +00:00
kleink f06533a1ee Add definitions of C99 integer format conversion macros. 
XXX Fastest minimum-width integer types haven't been decided upon yet.

 2001-04-15 15:29:02 +00:00
kleink c544d84b41 Catch up with ansi.h rev. 1.12: define SIZE_T_MAX and SSIZE_MAX as long 
integer constants in ELF environments.
 2001-04-15 14:16:08 +00:00
kleink 80ad23a5da Catch up with ansi.h rev. 1.12: define intptr_t and uintptr_t as long 
integers in ELF environments, like is done with ptrdiff_t.

kleink 7affdab52e Add definitions of C99 minimum-width and greatest-width integer types. 
XXX Fastest minimum-width integer types haven't been decided upon yet.
 2001-04-14 12:19:49 +00:00
thorpej bf2dcec4f5 Remove the use of splimp() from the NetBSD kernel. splnet() 
and only splnet() is allowed for the protection of data structures
used by network devices.
 2001-04-13 23:29:55 +00:00
kleink 9133b51cd8 Replace the 'unsigned __COMPILER_INT64__' construct with a new name, 
__COMPILER_UINT64__, to be supplied - if such a case is made, it shouldn't
be assumed that the unsigned type-specifier may be applied to it.
 2001-04-12 22:01:18 +00:00
thorpej c031c366f6 Add spluba(). 2001-04-12 19:16:06 +00:00

ragge e4d9af4b42 A bunch of new CPUs that are supported, from Michael Kukat 
(michael@unixiron.org). Among them are 4000/400, 4000/500 and 4000/105A.

thorpej d74e432ed3 Make softclock a generic soft interrupt of the API is available, 
adding the requisite void * argument to softclock().
 2001-01-15 20:19:50 +00:00
thorpej 45de366b2e Rename __GENERIC_SOFT_INTERRUPTS to __HAVE_GENERIC_SOFT_INTERRUPTS, 
and place the definition in <machine/types.h>.  This can now be used
as a flag to indicate whether or not <machine/intr.h> can be included
to get the generic soft interrupt API.
 2001-01-14 23:50:28 +00:00
thorpej d85a75f583 Make sure everybody has an splvm() and equate it with splimp() (splimp() 
is the historical name for this interrupt level, and the historical name
is going to go away in the near future).
 2001-01-14 02:00:37 +00:00
matt 27980172f6 Add the types needed by the new locale code. 2001-01-13 03:48:26 +00:00
takemura c5fd828440 replace 'long long' with int64_t to compile stand alone program with 
compiler other than GCC.
 2001-01-03 10:08:55 +00:00
matt 4622cfafe0 Redefine the memset/memmove/bcopy/bzero/memset macros to use more agressive 
constraints in their inline asm.  Gcc generates much better code now.
 2001-01-02 04:03:42 +00:00
ragge a81d92ef69 Add prototype. 2000-12-02 17:08:32 +00:00
chs 2116915a30 eliminate TRUNC_PAGE() and ROUND_PAGE() in favor of their 
lowercase counterparts.  also, a little misc cleanup.
 2000-11-21 05:49:07 +00:00
matt b605c997e2 Commit changes to SCSI working on the VS4000/9x. "Don't overthink the 
plumbing!  Duh!".
 2000-11-16 19:25:40 +00:00
matt 960800cbb8 Convert some spaces to tabs. 2000-11-15 00:49:31 +00:00
thorpej fb50850754 We use 4K VM pages on the VAX. Make PAGE_SIZE and friends into 
compile-time constants.
 2000-11-14 19:49:57 +00:00
ragge 7ac8ee6f59 By accident, a previously unused bit in the PTE got used as wired bit. 
Because of this kvtophys() of wired pages did set the leftmost bit, causing
the pager to hang while swapping. This is now fixed by using another
free bit in the PTE as wired bit instead.
This fixes PR#11121.

Many thanks to Chuck Silvers that found what the problem was!

matt 98e5e148fa Since cpu_switch (aka Swtch) is now called at splsched() with sched_lock 
locked, cpu_exit needs to do that too.  Since in the lock debug case we
have to use a CALLS which wipes out R0-R6, change the convention for Swtch
so that the proc is passed in R6 and that R6 is clobbered.  This is so
Swtch itself doesn't have to save/restore the proc pointer explicitly.
 2000-08-27 00:21:46 +00:00
thorpej 4db6fc7542 Make need_resched() take a "struct cpu_info *" argument. This 
causes gives a primitive form of processor affinity.  Its use in
roundrobin() still needs some work.
 2000-08-25 01:04:06 +00:00
thorpej 58e7a6954b Add spllock(). See spl(9) for details. 2000-08-22 19:46:26 +00:00
thorpej 23a7f255d4 Make sure we provide splsched() as described in spl(9). 2000-08-21 02:06:31 +00:00
