bjh21 3c88c46567 In {early,late}_abort_fixup(), return ABORT_FIXUP_FAILED, rather than 
panic'ing, if we hit an instruction we can't fix up.  This saves 250-odd bytes
of code, and should allow the caller to print a more useful message.

bjh21 f594a52dae late_abort_fixup: Get the indentation right! 2001-06-02 22:08:11 +00:00
bjh21 54a986d7fc Replace arm6_dataabt_fixup() and arm7_dataabt_fixup() with early_abort_fixup() 
and late_abort_fixup(), based on the abort model in use, rather than the CPU
type.  This cleans up the code and makes it smaller.  Only tested on an
ARM6 -- I can't find my ARM710a card right now.

bjh21 7089595665 Initial cpufunc operations for ARM3. Not actually used yet. 2001-06-02 19:01:03 +00:00
bjh21 c81d426dcf Save R14 (in a proper stack frame) around {read,write}_multi_1, since page 
faults can corrupt it on arm26.
 2001-06-02 11:15:56 +00:00
bjh21 ac0d39dfe8 Add write_multi_1(). 2001-06-02 10:44:56 +00:00
mrg 67afbd6270 use _KERNEL_OPT 2001-05-30 11:57:16 +00:00
bjh21 f15491e9d3 Move the declarations of blockio.S functions from katelib.h to a new, exciting 
<arm/blockio.h>.  katelib.h includes it for compatibility.
 2001-05-30 00:16:36 +00:00
bjh21 d51c27dfa8 Add read_multi_1() which does what it says fairly fast. 2001-05-30 00:14:09 +00:00
bjh21 7d9a4dbad7 Move blockio.S from sys/arch/arm32/arm32 to sys/arch/arm/arm, since I want to 
start using it on arm26.

hpcarm gets to keep its own version, since it's not identical and I haven't
got an hpcarm box to test.

chs e44e9dec8a replace vm_page_t with struct vm_page *. 2001-05-26 21:27:02 +00:00
chs 118ddca24a replace {simple_,}lock{_data,}_t with struct {simple,}lock {,*}. 2001-05-26 16:32:40 +00:00
chris cbf8e0eb95 Add a files.footbridge for inclusion by cats and netwinder. This is to make moving of the footbridge dir easier (when it eventually moves from arm32) 
Also remove EBSA285 defopt from the netwinder file as the netwinder isn't an eval board.
 2001-05-23 21:21:42 +00:00
chris 8901caf8ff Create an asm based version of in4_cksum based on the sparc version. 
Also don't compute psuedo header for nxt == 0
 2001-05-23 19:33:48 +00:00
bjh21 330163a77f Include opt_cputypes.h, since we use CPU_*. 2001-05-13 14:41:56 +00:00
bjh21 b9ded015f4 strstr() is no longer used in the kernel. G/C it. 2001-05-13 14:17:36 +00:00
bjh21 e2b24925d1 Use get_bootconf_option() to find boot options, rather than home-grown 
strstr()-based hacks.
 2001-05-13 13:53:08 +00:00
bjh21 0ea71ec5ea Make use of a.out or ELF symbols dependent on the compile-time definition of 
__ELF__.
 2001-05-13 13:51:08 +00:00
bjh21 e8fd2642a9 Don't include parse_cpu_options() unless we're going to use it. This fixes 
a warning on arm26.
 2001-05-13 13:50:01 +00:00
bjh21 2af5062ab7 Add <machine/bootconfig.h> on arm26, and add an <arm/bootconfig.h> for it to 
include (since all the contents are MI).
 2001-05-13 13:46:23 +00:00
bjh21 61044be691 Move get_bootconf_option() into a new file, sys/arch/arm/arm/bootconfig.c, 
since it's in no way machine-dependent.  It's not really ARM-specific either,
but I don't think it's useful enough to be made part of the MI kernel.
 2001-05-13 13:44:33 +00:00
bjh21 6d4648fa03 Move "defopt PMAP_DEBUG" into files.arm, since it's used by code in arch/arm. 2001-05-06 18:31:14 +00:00
bjh21 f9087c439b Move cpufunc stuff from arm32/arm32 to arm/arm. The only change involved is 
to add recognition of the SA-1100 and SA-1110 for compatibility with hpcarm
(which is now using this code as well).
 2001-05-06 18:01:42 +00:00
simonb 6a511e05e2 Be consistent with limit constants: 
- use "U" suffix for unsigned constants
 - use "L" suffix for long constants
 - use "UL" suffix for unsigned long constants
 - use hexadecimal instead of decimal

Fixes build problems with vi (now that warnings/errors are enabled) on
mips, powerpc and arm platforms.

bjh21 8afb876f73 Make the common <arm/profile.h> work on arm26 and arm32, choosing whether 
to munge R15 or not at runtime.  Also make it work with both ELF and a.out.
 2001-05-04 00:11:15 +00:00
bjh21 262c7835b0 In an ELF kernel, don't try to find an a.out symbol table. 2001-05-02 19:10:29 +00:00
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.

thorpej fe664428c8 Garbage-collect pmap_page_index(). 2001-04-25 17:35:00 +00:00
bjh21 63692f5771 Rather large overhaul. Mostly cosmetic, but also: 
Provide PROC_PC on arm26.
Provide working CLKF_INTR on arm26.
Make setsoftast a macro everywhere.
 2001-04-24 18:20:21 +00:00
thorpej 1c3a62e066 Sprinkle pmap_update() calls after calls to: 
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).

These calls are relatively conservative.  It may be possible to
optimize these a little more.
 2001-04-24 04:30:50 +00:00
thorpej 55044638aa Remove pmap_kenter_pgs(). It was never really adopted by 
anything, and the interface itself wasn't as flexible as
callers would have probably liked.
 2001-04-22 23:42:11 +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 82065e8a0b Update the comment for pmap_update(). 2001-04-21 17:13:12 +00:00

toshii 61ff48a82e In pmap_allocpagedir(), check if uvm_km_zalloc of ptpt is successful, 
and handle alloc failure case.

matt 1a5fe5b583 Split cpu from mainbus so that cpu can attached to other buses (like ofbus). 2001-04-20 18:08:48 +00:00
rearnsha 50e1e30747 Put back that old (not) unused include file. But only include it 
when ARMFPE is defined.  Since that is the only time we use it.
 2001-04-18 20:27:33 +00:00

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.

irq_entry accesses here.

bjh21 bfc2063e69 Create an ARM2-specific undefined-instruction handler which deals with the 
undef/SWI bug and handles emulating SWP.

Untested bacuse my ARM2 machine isn't currently set up.
