matt 65e94f7ef4 close the i386 ibcs2 machdep.h; nothing really machine dependent in it yet. 1999-11-16 00:46:25 +00:00
kleink 522cbf0248 Update to match new SVR4-style definition names in <sys/exec_elf.h>. 1999-10-25 13:55:06 +00:00
ragge 16a09f9b9c Remove the vmapbuf()/vunmapbuf() routines. They are quite unneccessary 
on a machine that has MMU for its I/O devices.
 1999-10-22 21:14:34 +00:00
ragge 4021578d6e Add routines to copy to/from a user process from/to the vsbus DMA area. 1999-10-22 21:10:12 +00:00
ragge ae7e9d1571 Protect against multiple includes. 1999-10-21 20:01:36 +00:00
thorpej 11cae42531 Centralize the declaration and clearing of `cold'. 1999-09-17 19:59:35 +00:00
ragge fe8a330be5 Styr upp deklarationen av clockchippsparametrarna. 1999-09-06 19:52:52 +00:00
ragge 56f0f92bef Add some external variables. 1999-08-30 21:18:17 +00:00
matt 82d58cbe82 export elf_machdep.h 1999-08-21 23:35:44 +00:00
matt 741f18b695 Initial VAX ELF32 support (mostly untested). It's checked primarily for 
testing and archival for now.  I don't expect anyone to work with it
since the binutils and gas changes are still pending.  But you got to
crawl before you walk.

simonb 3c185af5fd Include <sys/endian.h> after defining whether where are little- or 
big-endian.  i386, pc532 and vax still include <machine/byte_swap.h>
and define macros for the {n,h}to{h,n}*() functions.  mips also
defines some endian-independent assembly-code aliases for unaligned
memory accesses.
 1999-08-21 05:53:50 +00:00
simonb 06a92524c2 Include <sys/bswap.h> for function prototypes. i386, pc532 and vax 
still include <machine/byte_swap.h> and define macros for some of
the bswap*() functions.
 1999-08-21 05:39:51 +00:00
thorpej 28fb7c1eb8 Define cpu_number() as discussed on tech-smp. 1999-08-10 21:08:05 +00:00
ragge bc163ccc30 Clean up all bus handling stuff, it has become a mess the latest years. 
Add a new bus; "ibus" that is the internal MicroVAX bus.

thorpej d936f02b0b Implement priority raising, and use it as appropriate. 1999-08-05 18:48:55 +00:00
thorpej 37554502cf Correct a comment. 1999-08-05 18:31:06 +00:00
thorpej eb20bbc780 Change the semantics of splsoftclock() to be like other spl*() functions, 
that is priority is rasied.  Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.

This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).

XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX.  This platforms still have this bug until their
XXX spl*() functions are fixed.

ragge 43bbc0f5c7 Protect against multiple includes. 1999-08-03 19:53:23 +00:00
ragge 8f9615d62c A bunch of changes: 
- Free pte pages not in use anymore.
- Inline pmap_extract().
- Fix annoying page reference/modify bug. Fixes PR#7858 & PR#7859.
 1999-08-01 13:48:06 +00:00
ragge 1647688f0d Use pmap_steal_memory() for early memory allocation. 1999-06-30 19:31:33 +00:00
ragge 1e7b5cf8ae Wrong definition of SID for MicroVAX I, from Brian Chase. 1999-06-28 13:13:53 +00:00
ragge cb57cab9b1 Add macros to round/trunc vax pages. 1999-06-20 00:53:58 +00:00
cgd 7c02d93c04 nuke current definitions provided by __BUS_SPACE_COMPAT_OLDDEFS. 
I'll do what I can to make new ones soon.  8-)
 1999-06-18 04:49:24 +00:00
thorpej 0288ffb53a pmap_change_wiring() -> pmap_unwire(). 1999-06-17 19:23:20 +00:00
thorpej f5a527bb4e Remove pmap_pageable(); no pmap implements it, and it is not really useful, 
because pmap_enter()/pmap_change_wiring() (soon to be pmap_unwire())
communicate the information in greater detail.
 1999-06-17 18:21:21 +00:00
ragge f6d61fb6ad Add an define for SGMAP. 1999-06-06 19:07:11 +00:00
ragge d55d0ac4b5 Add some more IPRs for KA670. 1999-06-06 19:06:29 +00:00
ragge 64572c459a sgmap files, copied from the Alpha port and modified for vax. 1999-06-06 18:58:50 +00:00
ragge 22b5707362 Complete support for VAX 4000/300. From Michael Kukat. (michael@camaronet.de) 1999-06-06 14:23:46 +00:00
ragge ad1db202f7 bus.h'ify more of the vax code. 1999-05-24 20:10:30 +00:00
ragge 373e7cc828 Rewrite the "emulate page reference bits" code to avoid a bunch of 
pv_lists traversal and unneccessary page faults.
 1999-05-23 23:03:44 +00:00
ragge 539f825799 Better and more understandable way to find out CPU type. 1999-05-23 22:56:53 +00:00
christos c596c324e3 Define __builtin_*() for lint 1999-05-03 16:30:31 +00:00
ragge a5ce96e985 EEEK! The signal changes a while ago caused the user struct to be 
on top of the "red zone" in the kernel stack. This phenomenon has
caused many unexplainable things to happen the last year.
 1999-05-02 17:28:43 +00:00
ragge fc6020e344 Real-time clock is started on the same way on all CPUs, there is no 
need for a special CPU-dependent hook for this.

thorpej 5d82bfc656 Garbage-collect VM_MBUF_SIZE. 1999-04-26 22:47:34 +00:00
ragge e9689cc9bd Use "access_type" in pmap_enter() more intelligent. 
Allocate device register space bigger than the logical page size
from the kernel map, thus decreasing the pre-allocated page table memory.
 1999-04-17 00:01:18 +00:00
ragge 71a57b22eb Use the pool allocator for mbufs instead of a separate submap. 1999-04-14 23:42:00 +00:00
ragge 797a7428d6 First towards use of bus.h routines on vax. Allocate DMA memory for 
LANCE chip on vaxstations.

pk ca0b7aaa87 Ungarble the copyright notice. 1999-04-12 20:57:52 +00:00
mrg d2397ac5f7 completely remove Mach VM support. all that is left is the all the 
header files as UVM still uses (most of) these.
 1999-03-24 05:50:49 +00:00
drochner 76fa1751fe Add a macro to check for sufficient pointer alignment in bus.h context, 
"BUS_SPACE_ALIGNED_POINTER()".
Equal to the param.h "ALIGNED_POINTER()" normally, but obeys additional
requirements of the bus_space_xxx_n() macros. (BUS_SPACE_DEBUG)

thorpej a77ccfe460 Garbage-collect. 1999-03-20 01:40:25 +00:00
ragge f9b0eec83a Change vsbus to take a locator for all devices. 
Figure out interrupt vector/mask on vsbus by forcing all devices to
generate interrupts in the match routine, like on unibus.

ragge fb6b53bfe4 Basic KA48 (VAXstation 4000 VLC) support. 
From Michael Kukat <michael@camaronet.de>
 1999-03-09 12:57:57 +00:00
ragge 816acbe3ac pmap_physseg must be visible. 1999-03-06 11:11:11 +00:00
ragge 13daba04a1 Another giant change: Allocate register space dynamic instead of compiled-in. 
This is done on a physical page size basis, instead of virtual (as the
(on vax yet non-existing) bus_* routines does). This is similar to the
way uba allocation is done.
 1999-02-02 18:37:20 +00:00
mycroft 897a8a7f29 Mark [hn]to[nh][ls]() with __const__, so they are subject to CSE. 1999-01-24 12:55:01 +00:00
mycroft ec253b6315 Use __builtin_next_arg(). Fixed PR 6862. 1999-01-22 14:14:32 +00:00
ragge bef0af5311 Allocate (almost) all interrupt vectors dynamically. Simplifies much 
work when adding support for new machines and devices.
