bjh21 d0b6f0f1cd Changes to interrupt accounting:
NULL "name" argument to irq_establish indicates that the device will maintain
an evcnt structure for this interrupt.  In this case, irq_establish will still
maintain its own count (for DDB machine irqstat), but won't attach it to the
global list.

Change use of ev_group and ev_name to follow guidelines in evcnt(9).

Switch arckbd(4) over to the new arrangements.

bjh21 fe3273fbb4 Patch from PR kern/8001, submitted by Rafal Boni.
This adds support for EtherExpress/16 cards with 16k of RAM, and in the
process adds general support for PIO mode on these cards.  This entails
changing the way the i82586 driver handles bus barriers, since it doesn't
allow for strange cases like this.

This has been tested on the i386 port with the 'ix' driver in both
16KB (which was the source of the problem) and 32KB modes, as well
as with the 'ef' driver.  I've tested it (briefly) with 'ei' on arm26
as well.  In theory, drivers other than 'ix' should follow precisely the
same code paths as before.

bjh21 1178bf4219 Initial potentially sharable <arm/armreg.h>. Used by all arm26 code. 2001-01-22 22:10:39 +00:00
jdolecek 8b24036797 Require the machine-dependant DDB commands to be in db_machine_command_table[]
and link it directly to db_command_table[] so that it's not necessary
to do this at runtime. Make db_machine_command_table[] const on all ports.
g/c now unneded stuff, like db_machine_commands_install(), db_machine_init()

bjh21 8805bd8b56 Unify arm26 and arm32 trapframe structures. The unified trapframe is the same
shape as the old arm32 one, but there are a few #defines to keep arm26 code
happy.  Anything that depends on the precise shape of the trapframe,
and especially on being able to treat it as an array of registers, has been
updated.
2001-01-20 17:14:19 +00:00
bjh21 2c89ce7e74 Add <arm/frame.h>, for shared stack frame structures. Currently, only sigframes
are common.

jdolecek c1fc5392f5 adjust ddb variable access functions to have first arch 'const', make db_[e]regs[] const 2001-01-18 10:55:29 +00:00
fvdl c7f1462f3e Add machdep file for procfs. Currently only used for linux-style
/proc/cpuinfo (only active when procfs is mounted with -o linux).
For ports other than the i386 this currently produces an empty
string.
2001-01-17 00:07:18 +00:00
bjh21 f575270d81 Switch over to using the arm32 sigcontext structure.
Yes, this causes binary incompatibility.  Yes, it's Evil, Bad and Wrong.
Nonetheless, I think it's probably the least unpleasant way to get close to
binary compatibility with NetBSD/arm32, and a very much doubt there are any
arm26 binaries out there that depend on the old shape of struct sigcontext.

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.

thorpej 6f0dfa5049 splimp() -> splvm() 2001-01-14 03:32:20 +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).

bjh21 a5ef6e1f81 Move db_disasm.c into sys/arch/arm/arm. Use arm26 version, since it should

bjh21 6fa98146d5 Start merging actual code in arm32 and arm26:

Also move specification of other checksum stuff to files.arm, even though we
use the MI code for that.

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

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,

for the mess.

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.

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

bjh21 5b4c3dc909 Disable media autoselection entirely, but use whatever medium the card was
