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.

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.
