bjh21 a6b4c8d3da Strip the PSR bits off values of R15 before passing them to _mcount(). This
makes call-graph profiling actually work (hooray!).
2001-04-30 23:41:11 +00:00
bjh21 e5b19b546c Add two functions, int_off_save() and int_restore(), for mcount to use to
disable interrupts without getting into a loop or screwing up irq_handler().
Also use them.

thorpej 2b27ac7a99 Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for
each vm_page structure.  Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM.  These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg.  As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now).  Changes to other pmap
modules will follow.

bjh21 45eb40e8d3 Minimal implementation of cpu_sysctl(). 2001-04-29 15:13:45 +00:00
bjh21 e9c8a1fbb5 Add ipfilter, rnd, vcoda and raid. 2001-04-28 17:41:01 +00:00
bjh21 271fb855ce Arrange to restore R14 on return from __mcount, so that profiled assembler
routines will work.  We could put this in _PROF_PROLOGUE, but this seems
lighter-weight and possibly cleaner.
2001-04-26 22:09:57 +00:00
thorpej a60e816e7a Provide a pmap_resident_count() that simply expands to 0. 2001-04-25 18:03:19 +00:00
bjh21 90dfa8d8ff Undo my accidental revival of pmap_kenter_pgs(). 2001-04-25 16:30:03 +00:00
bjh21 7cf0a5e592 Arrange the "unamanaged" pages (entered through pmap_kenter_pa()) are tracked
and ignored as necessary.
2001-04-25 14:42:31 +00:00
bjh21 05d087e7c7 Remove definitions of CLKF_*. They're defined in <arm/cpu.h> now. 2001-04-24 18:15:44 +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 ec66f67f3a Use pmap_kenter_pa() rather than pmap_kenter_pgs(). 2001-04-22 23:28:52 +00:00
thorpej 69abdbf60c Undo a misguided previous change to the pmap_update() API. 2001-04-22 23:19:26 +00:00
thorpej 5871b80f00 Use uvm_pageboot_alloc() for early memory allocation, rather than
calling pmap_steal_memory() directly.  On these platforms, since
uvm_pageboot_alloc() is a wrapper around pmap_steal_memory(), there
is no functional change.  This is merely for API consistency.
2001-04-22 18:21:48 +00:00
thorpej cfb5c7ed9f Make pmap_virtual_space() a required pmap function, even on platforms
which have pmap_steal_memory().  This is to reduce the API differences
between pmaps that implement pmap_steal_memory() and pmaps which do
not.

Note that pmap_steal_memory() needs to adjust *vstartp and/or
*vendp only if it used addresses within the range provided to UVM
via the pmap_virtual_space() call.  I.e. it is not necessary to do
so in any current pmap_steal_memory() implementation.

bjh21 8eed59a146 Move arcpp so it attaches before podulebus. 2001-04-22 15:26:07 +00:00
bjh21 11b40e716c Add arcpp. Not in GENERIC because I don't know it works. 2001-04-22 15:02:51 +00:00
bjh21 856547f067 Driver for Archimedes parallel ports. I haven't got a parallel printer, so
this is currently untested.
2001-04-22 15:01:25 +00:00
bjh21 2a1570b5d9 Add functions to twiddle the latch bits, patterned after the ones in Linux. 2001-04-22 15:00:13 +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
bjh21 660a20cd22 Add a skeleton driver for the random latches on the Archimedes, which are
shared between the printer port and floppy drive.  Useful facilities will be
added when I know what I need.
2001-04-22 00:26:35 +00:00
bjh21 85e1abfb39 Keep track of interrupt depth. With forthcoming changes to cpu.h, this gets
us accounting for interrupt time.
2001-04-21 18:51:17 +00:00
bjh21 e66c66730e Remove <arch/arm26/podulebus/podulebus.h>. Podulebus driverd now include

bjh21 020a050984 Randomize the statclock period properly. We use the same algorithm as the
sparc port.

bjh21 5a15be6a18 Don't panic on a stray IRQ, just log it and hope it goes away. This works for
my acemidi card at least.

bjh21 cee3528adc When checking if an IRQ is active, check for _all_ the right bits' being set,
not just some of them.
2001-04-14 19:58:58 +00:00
bjh21 e0e3b230c1 Remember to initialise the interrupt handle.
Bugs like this are my penalty for having my only supported podule in slot 0.
2001-04-14 18:39:20 +00:00
kleink 7affdab52e Add definitions of C99 minimum-width and greatest-width integer types.

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
bjh21 d3c7885319 Make sure that every time we touch the referenced/modified bits, we do a
pmap_update_page() to get all the mappings of that page up-to-date.
2001-04-13 16:37:28 +00:00
bjh21 991d163aa2 Remove code from pmap_fault() that ws trying to do referenced/modified
emulation on kernel pages (and getting it wrong).

bjh21 d039e70428 Remove the "asc" driver. It's never worked, and we should have an MI version
sometime.
2001-04-10 21:33:00 +00:00
bjh21 5677634e50 Small comment correction. 2001-03-28 13:04:57 +00:00
bjh21 8bd452c648 Create an MI Ether3 driver. It's derived from the arm26 driver, which uses
my MI SEEQ 8005 driver, which is based on the arm32 ea driver.
2001-03-24 00:14:52 +00:00
bjh21 2714607c72 Add podulebus_shift_tag, which generates a bus_space_tag_t with a specified
address shift (stride).  This is necessary because many podules have standard
chips with odd address-bus wiring to allow for using LDM for
bus_space_*_multi_*().
2001-03-24 00:10:42 +00:00
lukem 723cd818d8 move duplicate definitions for:
pc, lpt, joy, ocis, apm, satlink, i4bctl, i4brbch, i4btel, i4btrc, i4b
from the port-specific arch/*/*/conf.c files into sys/conf.h

bjh21 de59def2f2 Remove spurious #define mod_base. 2001-03-20 23:29:07 +00:00
bjh21 86d6442c28 Move machine-dependent podulebus headers to <machine/podulebus_machdep.h>.
<dev/podulebus/podulebus.h> is the canonical file to include, and includes
<machine/podulebus_machdep.h>.
<arch/${MACHINE}/poudulebus/podulebus.h> remains for backward compatibility.

bjh21 61e80eef9b As Richard Earnshaw pointed out, bus_space_copy_1() and bus_space_copy_2()
had the wrong names and did the wrong things.  Both are now fixed.
2001-03-20 22:56:16 +00:00
bjh21 0fe2c0aedc These have moved to sys/dev/podulebus. 2001-03-20 00:13:16 +00:00

chs c40daf0aed change uvm_winsize to uvm_winshift so that we can avoid division
by a non-constant value.
2001-03-19 00:29:03 +00:00
bjh21 5c98fe3fec Gratuitous change of signature for podulebus_irq_establish(). It now takes
an opaque podulebus_intr_handle_t, which can be found in podulebus_attach_args.
It's actually the slot number, but don't tell anyone.
2001-03-18 15:56:04 +00:00
bjh21 949f93d279 If uvm_fault() returns an error, pass it on to the pcb_onfault handler
if there is one.  They already arrange to return it to their callers.

bjh21 16198f2b92 Podulebus convergence:
pa_memc_[th] -> pa_mod_[th]

bjh21 9dfd56f6dc Make this compile with "options DEBUG" again. 2001-03-16 18:11:57 +00:00
chs ac3bc537bd eliminate the KERN_* error codes in favor of the traditional E* codes.
the mapping is:

KERN_SUCCESS			0
KERN_INVALID_ADDRESS		EFAULT
KERN_PROTECTION_FAILURE		EACCES
KERN_NO_SPACE			ENOMEM
KERN_INVALID_ARGUMENT		EINVAL
KERN_FAILURE			various, mostly turn into KASSERTs
KERN_RESOURCE_SHORTAGE		ENOMEM

files.{arm26,arm32,dnard}.
2001-03-14 14:39:45 +00:00
bjh21 c3c5158d00 Change the value of tf_pc in undefined-instruction handlers on arm32. It now
always points to the undefined instruction in question.  It's up to the
handler to advance it to the next instruction if it wants execution to
continue there.  This is how things have always worked on arm26.
2001-03-13 23:56:48 +00:00
bjh21 a7ba6bb441 Update for new linked-list undefined-instruction handler. 2001-03-13 21:00:13 +00:00

bjh21 b1475781a2 Make arm26 implementation of DDB slightly less gratuitously different from the
ARM one.  Also update for recent undefined-instruction handler changes.
2001-03-11 16:31:05 +00:00
bjh21 ce5529eabf Change undefined instruction handler to use a linked list for each
co-processor.  This is necessary so we can have several handlers for
CP0 (used as a catch-all for non-CP instructions).

Handlers are now removed using remove_coproc_handler(), rather than by calling
install_coproc_handler() with a NULL handler.

Because install_coproc_handler() can now allocate memory, there's a version
for use at boot time that doesn't.
2001-03-11 16:18:39 +00:00
bjh21 c6c5fda4be Use <arm/undefined.h> 2001-03-11 16:14:36 +00:00

bjh21 29e609e3c5 Update for recent changes to the i82586 driver. 2001-03-10 22:32:17 +00:00
bjh21 f6c36838ae Use the same undefined-instuction handler on both arm26 and arm32. The handler
is derived mostly from the arm32 version, but with a check for an obscure ARM2
bug thrown in.

arm26 fpu and cpu drivers use the new interface for catching undefined
instructions.

this lot in the last commit).
2001-02-25 18:28:27 +00:00
bjh21 96b16f75a6 Hack to allow arm26 to have its own "cpu" device. This device should really
be shared between all ARM ports, but the arm32 one is too ugly for me to

bjh21 a72248beab Reduce unnecessary differences between this and Makefile.arm32.
Also (more significantly), use the compiler's default -mcpu setting.  This

2001-02-13 22:54:25 +00:00
bjh21 f942342607 Fix a typo in the last change (eh_init_media -> eh_media_init). 2001-02-13 18:20:57 +00:00
bjh21 284047a2b2 Move sendsig() and sys___sigreturn14() from arm26/arm26/vm_machdep.c and
arm32/arm32/machdep.c into arm/arm/sig_machdep.c, merging and ANSIfying in
the process.

The code is based on the arm32 version, so I don't think anything should break
there.
