bjh21 5c09bd5fc5 Un-__P and remove function arg names. 2001-01-07 13:38:42 +00:00
bjh21 610a127a3d Fix a stupid = vs == bug that prevented the code working usefully at all.
While I'm here, fix all the other GCC warnings too.
2001-01-07 00:30:29 +00:00
bjh21 fa64805abd Specify (void) arguments, hence avoiding GCC warning. 2001-01-07 00:07:58 +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
bjh21 7866e2f2c9 Arrange that the return value of copyin() and friends be provided by
do_fault(), in preparation for do_fault() being able to get it from
uvm_fault().
2001-01-01 16:00:42 +00:00
bjh21 bc86e85531 Correct various initial comments, and provide a useful overview of how the
MEMC works, at the suggestion of chs.
2000-12-31 16:09:34 +00:00
bjh21 c1ad66d687 Whitespace cleanup. 2000-12-30 13:53:26 +00:00
bjh21 66c70101f3 Add a cache flush to pmap_fault() when it adds a r/w mapping, since there's
probably an old mapping around that we don't want to get stale.
2000-12-30 13:42:12 +00:00
bjh21 e9d5e8f1e5 Overhaul v(un)mapbuf: Don't worry about unmapping things (the pmap can handle
multiple wired mappings now).  Do worry about seeding referenced/modified
information correctly.
2000-12-30 13:33:15 +00:00
bjh21 e4c6b6f4e5 pmap_kenter_pa(): Seed referenced/modified information correctly. 2000-12-30 13:31:50 +00:00
bjh21 b3eae7d1c8 Since we need to have an aout_machdep.h, we may as well borrow the arm32 one. 2000-12-29 23:08:31 +00:00
bjh21 36f8a8d0f8 Purge vestiges of a.out support. 2000-12-29 23:07:29 +00:00
bjh21 00a01e20d8 Sync with arm32. No functional changes. 2000-12-29 22:42:23 +00:00
bjh21 df10cbcda9 Sync with arm32 (fixes warnings compiling /bin/sh and probably others). 2000-12-29 19:30:34 +00:00
matt a589927cbc Make identical to arm32 version. (add same parens, use __P, etc.) 2000-12-28 03:55:14 +00:00
matt f1f4acfb4d Remove reference to CLBYTES 2000-12-28 03:54:15 +00:00
matt 61b05af542 Except for the RCSID, this file is now identical with arm32/include/ansi.h 2000-12-28 03:52:50 +00:00
bjh21 c00a8ab5fd Calculate the required amount of screen memory, rather than just trusting the
number that RISC OS gives us (which may be far too large).
2000-12-27 22:13:42 +00:00
bjh21 9822871467 Add a special call to uvm_page_physload to register RISC OS's zero page as
free at startup.
2000-12-27 20:43:44 +00:00
bjh21 1b364c5082 pmap_confess() is unused and doesn't work any more. G/C it. 2000-12-27 18:38:50 +00:00
bjh21 c481cdca92 Overhaul of data-abort handling:
- Make data_abort_address() return the whole affected range, rather than
   just one end.
 - Don't rely on pmap_confess().  Instead, for LDM/STM, behave as if two faults
   had occurred, one at each end of the range.
 - Separate out fault handling into do_fault(), and call it from
   data_abort_handler() (twice) and prefetch_abort_handler().
2000-12-27 18:35:18 +00:00
bjh21 58e80f030f Two batches of changes:
1: Cleanup of syscall() -- treat the arguments as an array of register_t
   throughout.  This saves a few casts, and generally makes seeing what's
   going on easier.
2: Be a little more careful in the handling of data aborts on kernel
   addresses: don't use the kernel's map unless the access was actually from
   a kernel mode.  This is how the arm32 data abort handler behaves.
2000-12-27 16:57:09 +00:00
bjh21 186792c5b7 Use KASSERT for simple assertions. 2000-12-27 16:50:12 +00:00
bjh21 2433e71e6e Medium-sized pmap overhaul:
- Use UVMHIST for debugging messages, rather than printf
 - Rely on the caller of pmap_enter to tell us how to manipulate referenced/
   modified bits in the kernel pmap.
   [ Suggested by chs -- may need work on the rest of the kernel. ]
 - Split third-stage initialisation out of pmap_create() into pmap_init2().
 - Bug fix: when relocating pv_table, fix up all references to it as well.
 - Bug fix: in pv_release(), if pulling up a pv_entry to the head of the
   list, correct the reference from its pmap.
2000-12-27 15:16:04 +00:00
bjh21 ce3cd11d08 Unreasonably simple fix for PR#11817: Don't worry about duplicate mappings,
just get pmap_fault to shove them back in.  Crude, but effective.  Fix inspired
by Chuck Silvers.

This breaks pmap_confess, but it probably deserves to die.
2000-12-26 23:18:50 +00:00
bjh21 939baa9f0d Follow the herd: Use the MI md_root.c. 2000-12-26 19:55:52 +00:00
itojun efa2b7073c make mbstate_t bigger (32 -> 128 bytes).
XXX if you have libc after citrus locale import, please recompile libc,
and your applications that use mbstate_t (rather rare).  really sorry
for the mess.
2000-12-26 10:35:28 +00:00
bjh21 f1fc4edf08 In pmap_enter(), seed referenced and modified bits from access type passed in. 2000-12-23 23:06:51 +00:00
bjh21 5568314c66 Since the Arc's interrupt layout is fixed, only print IRQ numbers in
verbose mode.  This helps to ensure the kernel version number doesn't disappear
too quickly.
2000-12-23 21:49:13 +00:00
bjh21 7cce6a2816 Remove "machine" subcommands that duplicate "show".
Add "machine bsw" which does a bus_space_write_*().
2000-12-23 15:18:34 +00:00
bjh21 da1e6b7cfb Don't SIGSEGV a process just because we get KERN_RESOURCE_SHORTAGE. It might
go away.

Yes, this is a grotty hack.  The right solution is for uvm_fault to be less
pessimistic.
2000-12-23 15:12:54 +00:00
bjh21 95920110c7 Stub FPU driver -- identifies FPUs and warns they aren't supported. e.g:
cpu0 (root): ARM2
fpu0 at cpu0: FPPC/WE32206
fpu0: WARNING: FPU type not supported by kernel
2000-12-23 13:37:02 +00:00
bjh21 85aa3d3b8d G/c unused declarations. 2000-12-23 12:57:55 +00:00
jdolecek e9e91a0fb5 split off thread specific stuff from struct sigacts to struct sigctx, leaving
only signal handler array sharable between threads
move other random signal stuff from struct proc to struct sigctx

This addresses kern/10981 by Matthew Orgass.
2000-12-22 22:58:52 +00:00
bjh21 0c0d8f3775 Support for identifying MAUs attached to EtherLan 200-series cards. 2000-12-22 22:21:37 +00:00
itojun 823498203f populate _BSD_MBSTATE_T_. add warning regarding to rune_t. 2000-12-21 06:03:47 +00:00
bjh21 15d214bd18 Looks like I got the state of the link-detect bit inverted. Fixing that
gets me working auto-media selection, which is nice.
2000-12-20 23:08:44 +00:00
bjh21 9ca53819f0 Actually use 10baseT when we say we will. 2000-12-20 22:48:15 +00:00
bjh21 4a33b50a91 Add eh(4). 2000-12-20 22:17:31 +00:00
bjh21 f8e732cd45 Use the podule loader code to get at the card description the official way,
and get our Ethernet address from there.  This works on both of my cards.
2000-12-20 10:59:32 +00:00
bjh21 b66603547a Add support for using RISC OS podule loaders to get at ROM chunks on podules.
By default, they aren't used, since most cards seem to put the non-OS-dependent
stuff in the main chunk directory.  i-cubed cards are a notable exception.
2000-12-20 10:57:38 +00:00
bjh21 5b4c3dc909 Disable media autoselection entirely, but use whatever medium the card was
found using (presumably having been set up by RISC OS) as the default.
NB that this doesn't seem to be right for the EtherLan 200.
2000-12-20 00:01:56 +00:00
tsutsui cb7f7c7f3b Remove "rnd is EXPERIMENTAL" comments. 2000-12-19 15:51:47 +00:00
bouyer c71f40d166 Add pseudo-device vlan 2000-12-19 10:42:02 +00:00
bjh21 c25ab2f1ec Rudimentary facilities for extracting the card's Ethernet address from the
ROM.  Only works on one of my two cards, though.  It looks like we'll need
to use the RISC OS loader on the podule to get this right.  *mutter*
2000-12-18 00:46:47 +00:00
bjh21 4942923809 Handle detecting the available media and state of medium selection links
on EtherLan 100 (and presumably 500) boards.
2000-12-17 22:29:26 +00:00
jdolecek cacec11253 delete obsolete comment 2000-12-17 15:52:39 +00:00
bjh21 72735aa75a Correct embarrassing null-pointer-dereference bug. Also fixes interrupt
enabling.
Default to 10base2 for now, since automatic media selection doesn't work.
2000-12-16 18:24:36 +00:00
bjh21 3ebcd51009 I think bit 0 of the status register is the interrupt status on read. 2000-12-16 18:23:14 +00:00
bjh21 3c5709c088 Separate out checkvectors(), so it can be used elsewhere for debugging. 2000-12-16 16:45:11 +00:00
bjh21 395a883e48 Pull across arm32 rev 1.19:
Remove ALTENTRY().  It's dangerous and should not be used.
2000-12-14 20:50:56 +00:00
bjh21 e266a563d8 Filter out non-ASCII characters from podule descriptions.
I think my MIDI card had a \r at the end, which was confusing.
2000-12-14 20:40:29 +00:00
bjh21 84d111ea01 Move RCSID to the end of locore so it doesn't end up in zero page if we
compile with an asm.h which doesn't know about section .ident.
2000-12-14 20:30:03 +00:00
bjh21 a6b4048c85 Get ELF RCSIDs back 2000-12-14 20:26:42 +00:00
bjh21 14198dc0bd Sync with arm32 -- they've got ELF stuff there these days. 2000-12-14 19:28:12 +00:00
bjh21 acff6e4375 Use _C_LABEL rather than _C_FUNC. 2000-12-14 19:22:39 +00:00
bjh21 afb44982ee Correct the mangled-vectors check. 2000-12-11 23:51:58 +00:00
bjh21 0692c35dda Since BBBB correctly disables the CPU cache at startup, we now decide whether
to leave it disabled based on the bottom bit of cpu0's cf_flags.
2000-12-11 23:46:50 +00:00
bjh21 d606f7e6e0 Move most of the RISC OS shutdown into BASIC code.
Issue Service_PreReset to get the hardware to a sane state.
Use *ShutDown to log off fileservers.
Use the correct arguments to Cache_Control.
Using Service_PreReset seems to have rendered the Podule_ReadID trick
unnecessary, so g/c it.
2000-12-11 22:19:18 +00:00
bjh21 4f1ee09e5f It looks like UBC_WINSIZE needs to be at least PAGE_SIZE. 2000-12-10 14:28:45 +00:00
bjh21 4f5619bc7c Prototype kdb_trap(). 2000-12-10 01:31:48 +00:00
bjh21 7e79390d64 Delint. 2000-12-10 01:27:35 +00:00
bjh21 6073fc61bf Indirect the SWI handler through the current emulation, thus providing a
syscall() for MI code.  Hope it never calls it itself.
2000-12-10 01:18:52 +00:00
bjh21 477863502b DIAGNOSTIC check for mangled exception vectors. 2000-12-10 01:02:04 +00:00
bjh21 559ea94aca Fix arguments to ktrsys*() functions. 2000-12-09 18:57:17 +00:00
bjh21 6d66ade542 We no longer have zeropage.S. It was merged into locore.S last week. 2000-12-09 18:54:01 +00:00
bjh21 86dd29d1f5 Add a definition of BUS_SPACE_ALIGNED_POINTER. 2000-12-09 18:47:15 +00:00
bjh21 8df54708da If we get an odd IOEB type, tell the user. I have a feeling issue 1 A5000s
might trip this.
2000-12-09 18:04:05 +00:00
bjh21 38d918f85f Proper support for the Unix backplane in those machines that have one.
Not very well-tested, but it seems to work.
2000-12-09 17:52:44 +00:00
bjh21 facbe746d0 Provide friendly names for the IRQs as they're wired in normal machines. 2000-12-09 15:16:01 +00:00
bjh21 3e0d9a1b4a Fix multiple-file loading. Bump version number to 0.41. 2000-12-09 13:30:25 +00:00
bjh21 4c4e11c0f8 Merge zero page into the start of locore. This allows us to just map the
start of the kernel text segment in at address 0 to get zero-page properly
mapped.  This should save us one page, but that may need a bit of extra
shuffling before we can easily tell UVM about it.
2000-12-07 21:48:58 +00:00
bjh21 cb5273b547 First attempt at an EtherH driver. Can just about transmit and receive
packets.  Interrupt enabling is left to the RISC OS driver, medium selection
is untested and it's hard-wired to the MAC address of my card.  Not really
for production use.
2000-12-01 14:28:36 +00:00
bjh21 9307dc5373 Reduce default UBC_NWINS to save precious KVM. 2000-11-30 20:59:36 +00:00
bjh21 32b19479ca Drastically reduce PAGER_MAP_SIZE so we don't run out of KVM so soon. 2000-11-30 12:16:00 +00:00
bjh21 eb0dc305da Insert clock low after ack bit. 2000-11-26 18:53:12 +00:00
bjh21 f801b80192 Zero-length reads seem to confuse the chip, so don't do that. 2000-11-26 18:12:36 +00:00
bjh21 70562420ce Support multiple files on the command line (they're catted together).
Ditch a.out support while we're here (to save updating it).
2000-11-25 18:30:23 +00:00
bjh21 98253a5467 It seems that all versions of BBC BASIC V can load a text file specified on
the command line, so we don't need to tokenize it first.

This makes it less than clear what file type BBBB should have, so let's not
make an issue of it.
2000-11-25 13:32:51 +00:00
bjh21 564a044dcb Using bsd.man.mk looked silly without a man page. Use bsd.prog.mk without
PROG instead.
2000-11-22 00:36:22 +00:00
bjh21 fc955e1104 Move BBBB out of the kernel tree so other architectures can see it. 2000-11-22 00:32:53 +00:00
bjh21 c4eb6c6325 Rudimentary manual page for BBBB. 2000-11-22 00:18:47 +00:00
bjh21 986c78ced4 New mechanism for building the tokenised version of BBBB under NetBSD. This
saves us having to keep a uuencoded version around.
2000-11-21 23:47:37 +00:00
bjh21 99899665e8 Move of BBBB to a more sensible location.
Look in sys/arch/arm26/boot/BBBB,fd1 for old commit messages.
2000-11-21 23:44:24 +00:00
chs c62d17a551 rationalize the use of b_flags for geteblk() buffers.
rather than assigning to the whole field, set or clear individual flags,
which implies that the B_BUSY and B_INVAL flags will remain set.
this allows us to make the assertion in brelse() that B_BUSY is set,
which is the purpose of all this.
2000-11-20 08:24:08 +00:00
bjh21 b4ef973eab IDE hard discs seem to work -- turn them on by default. 2000-10-14 23:46:40 +00:00
bjh21 a449e4af6d Ensure that the IOC is attached before any other devices, mostly because
the UPC driver needs to know whether the system's got an IOEB in it.

The way this is implemented is a mess -- I need to get my mind round
autoconfiguration again.
2000-10-14 23:44:42 +00:00
bjh21 7270db5ec0 Change to semantics of irq_establish: IRQs are now enabled by default, which
I think is the same as all other ports.
2000-10-14 23:41:01 +00:00
itojun 9e47af8814 enable rnd device. they are now mandatory for ssh/sshd support,
so it makes more sense to enable it.
please disable them if there's any issues, but in that case, in-tree
ssh/sshd won't work.
2000-10-04 03:35:53 +00:00
jdolecek b1f94e26ab don't specify number of ptys if >= 16 (current default initial number)
pty comments: normalize and g/c what is no longer relevant
2000-09-24 15:59:26 +00:00
jdolecek 49c105ffdb add new macro BOOT_FLAG() (defined in <sys/boot_flag.h>) - this
maps standard boot flags to corresponding RB_* values
use BOOT_FLAG() in port's MD code as appropriate

as discussed on tech-kern, add new boot flags -v, -q for booting
verbosely or quietly, and corresponding AB_VERBOSE/AB_QUIET
boot flags; also add FreeBSD-compatible bootverbose macro and
NetBSD-specific bootquiet macro

for hpcmips, use new bootverbose instead of it's own hpcmips_verbose

Tested on i386, and to limited extend (compile of affected files) also for
mvme68k, hp300, luna68k, sun3.
2000-09-24 12:32:31 +00:00
bjh21 d0dfd74448 COrrect comment at top and add options NFS_V2_ONLY. 2000-09-23 12:58:26 +00:00
bjh21 b6ba812d35 Much juggling of pmap startup sequence:
* All of pmap_init is now deferred to the first call of pmap_create.  This
  allows us to allocate stuff dynamically using malloc.
* pv_table (which is needed before malloc is available) is temporarily
  allocated using pmap_steal_memory in pmap_bootstrap, and then
  re-allocated using malloc in pmap_create, with the old allocation being
  given back to UVM.  This should save some memory on small machines, but
  the malloc overhead probably soaks it up.
2000-09-23 12:54:47 +00:00
bjh21 3112fd4f14 Add a pmap_steal_memory implementation. This has two good consequences.
First, it reduces the kernel text segment by 1k or so.
Second, it should enable me to eventually allocate the pv_table dynamically.
2000-09-23 11:10:58 +00:00
bjh21 7751c0fd46 If we haven't got DDB in the kernel, there's not much point hanging onto the
symbol table.
2000-09-21 23:22:51 +00:00
