Rework how KERNOBJDIR functions; now it's always determined with
cd ${KERNSRCDIR}/${KERNARCHDIR}/compile && ${PRINTOBJDIR}
This is far simpler than the previous system, and more robust with
objdirs built via BSDOBJDIR.

The previous method of finding KERNOBJDIR when using BSDOBJDIR by
referencing _SRC_TOP_OBJ_ from another directory was extremely
fragile due to the depth first tree walk by <bsd.subdir.mk>, and
the caching of _SRC_TOP_OBJ_ (with MAKEOVERRIDES) which would be
empty on the *first* pass to create fresh objdirs.

This change requires adding sys/arch/*/compile/Makefile to create
the objdir in that directory, and descending into arch/*/compile
from arch/*/Makefile. Remove the now-unnecessary .keep_me files
whilst here.

Per lengthy discussion with Andrew Brown.

branches: 1.15.32;
Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

Use m68k/Makefile.inc.

fix multiplei repetitive typos in comments, messages and documentation. mainly because copy paste code big amount of files are affected.

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER! Some subsystems have

#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)

Reverted the CIA-timer based delay() to the pre-5.0 method of a calibrated
delay loop.
This fixes keyboard handshaking problems with some A1200 models since 5.0
and restores the precision for short delays on DraCo systems (the QuickLogic
timer has only a seventh of the CIA precision).
Changed the keyboard handshaking delay from 2000 back to 200ms, although
even the recommended 85ms were successfully tested on the most problematic
A1200 keyboards.
All those changes were tested on an A3000 and A1200 with 68060/50 CPU, and
previously discussed on the port-amiga ML.

Use appropriate macro during pmap initialization:
- use SYSMAP_VA, SEGSHIFT for Sysmap address and table entries
- use TIA_SIZE, TIB_SIZE for sizes of table entries

Now page size dependent numbers are almost replaced with proper macro.

Use PAGE_SIZE rather than NBPG.

Change the bootstrap procedure to avoid temporarily mapping physical memory.

Now, on the Amiga, we copy a small piece of code to chip memory and enable the
MMU from here.
On the DraCo, we setup %itt0 so that we shadow physical memory without
touching the page tables and very temporarily. The DraCo's memory layout
guarantees that there is no overlap in this case between physical and
virtual addresses.

This fixes a bug where Amiga's with physical memory at 0x200000 wouldn't boot
kernels >2M in size, and possibly other corner cases.

Sysptsize was patched, or if a large amount of Zorro3 space was needed.

Workaround for the incomplete fastmem loading scheme: put uptbase lots higher,
so that hopefully it doesn't get overwritten by the 1:1 mapped kernel copy.
See line 375 for an explanation.

Get rid of AMIGA_UPTBASE.
Replace it by a variable, which is initialized in amiga_init.c.
This will make the kernel actually work even if we have lots of Zorro-III
(or DraCo direct bus) i/o space.

Back out the defopt for M680?0. As pointed out to me, this breaks ports which
dont use the M680?0 the way Amiga, Atari, Mac68k, and X68k do. I must have
missed this in the past discussion about this project.

Move M680[2346]0 to opt_m68kcpu.h.
XXX Some explicit dependencies could be removed now from the individual
arch/$ARCH/conf/Makefile.$ARCH files, but this is still to be done.

Uhm... looks like I forgot this when doing the MACHINE_NEW_NONCONTIG stuff.
Sorry folks.

Fix a bug I think I introduced long, long ago. The bug would only show
up on systems that have Zorro I/O space allocated outside the Z2 I/O
region, and then only if kvm usage is high enough to begin allocating
pages already mapped for hardware mappings. Found and fixed by Niklas
Hallqvist on OpenBSD.

From niklas@cvs.openbsd.org:
Yay! This fixes a bug that has been there since day one of the amiga port.
We have never protected the kvm area that maps Zorro I/O registers in the
Z2 memory space from being allocated by the kmem_* routines. Lately kvm
usage has increased and we have needed more kvm allocated than earlier thus
this area have got allocated with random results. Most often resulting in
MMU fault panics, but also in hangs. This bug has stalled the amiga port
release builds for several weeks, but now I *hope* the amiga will have a
chance to be built and tested in time for 2.3.

Add the LIMITMEM workaround for the kernel address space size problem.
Will be removed as soon as the kernel can auto-adapt to its address space.

branches: 1.56.8;
s/amiga_round_page/m68k_round_page/

The delay loop needs 8 cycles, not 3, on the 68030; so use _that_ value
for the pre-calibration.

Get the boot partition offset from the boot loader. Also pass it when
doing a reload. The partition offset will be used to determine which
disk device was the boot device.

Switch off some more interupts on startup; switch off drcom interupts
at the right offset.

backout previous kprintf change

printf -> kprintf, sprintf -> ksprintf

a) replace our delay() with a Gordon Ross style one, calibrated at
clock_attach() time (for now).
This removes our dependance on the DraCo ROM access timing and frees
the second CIA on Amigas.
b) support for DraCo rev. >= 4 native timer chips.

Rename the watchdog enable bit to reflect its polarity.

Don't forget to shut up Fido.

Rewrite of the last bugfix wrt. Z2 bounce buffer memory allocation:

Don't manipulate the memlist passed from the kickstart rom + bootloader, as
we want it unchanged in case we boot via /dev/reload.
Instead, make z2mem_start known to pmap.c; and use int in pmap_bootstrap to
detect the right segment to correct and the amount.

XXX The transformation of z2mem from physical to virtual kernel addresses
in amiga_init.c must not be done before the pmap_bootstrap() call now!

Deal with two bugs in the bounce buffer memory reserve code:

If z2 memory is used for bounce buffers, it used to be stolen in
amiga_init.c, but would not be removed from the memory list there, but
in pmap.c the memory list would just be corrected.

a) the sizes subtracted got out of sync.
b) the memory segment to subtract from was guessed in pmap_init, and not
necessarily right. (e.g. consider a graphics board whose fraem buffer gets
mapped in by the RO at 0x200000, and a memory board which maps at 0x400000)

The new code subtracts the stolen aount of memory from the memlist parameter
given to the kernel by the loader, and pmap_init just doesn't see it anymore.

Fix two bugs which were inserted when adding '060 support:
- due to a merge error, 2 line were missing making all the kernel data area
cache inhibited.
- due to a misunderstanding of "kstsize" units, all but the first page of
the kernel segment table was copyback cached on the '040/'060 which
should have caused sporadic user process segmentation faults or
kernel endless loops on the '060, under heavy load (when lots of
userland pagetables are in-core), although the problem was not yet
observed.

Use the right microsecond delay address. To achieve this, also map that
piece of hardware into kernel virtual memory (was only a guess 'til now).
XXX Unfortunately, the hardware vendor reserves the right to change this in
future DraCo revisions. We must rethink delay() and DELAY(), at least for the
DraCo, soon.

Fix few more places where 040+060 rlevant stuff was only compiled for 68040,
preventing 68060-only kernels to work. (68060 only kernel is tested now by
using it to commit this patch).

Delete some occurences of kernel startup debug code, move others inside

First part of M68060 and DraCo support.

I've included a workaround for 2 of the CPU bugs in chips with Masks
1F43G and earlier, but didn't bother to deal with the can of worms

Startup modified to work with kernel loaded directly into fast memory.
This removes the need to have enough chip memory to load the kernel
when booting. Kernel memory is dual-mapped (VA == 0 and VA == PA)
for enabling the MMU, and the VA == PA mapping removed after start_c()
has completed. Chip memory is still required for the /dev/reload
process.

Missed a prototype for kernel_reload().

Add a check in the kernel reload device (/dev/reload) to protect
against the MMU switch code being in different locations between
the running kernel and the new kernel. Returns ENODEV if the reload
fails.
Change the error return from EFAULT to ENOEXEC when kernel_reload
gets a short write on the exec header.

Cleanup for -Wall and -Wstrict-prototypes

Merge thorpej-cfargs2.

branches: 1.119.6;
The Amiga and Atari ports abuse some autoconfiguration internals as part

branches: 1.118.2;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Implement the probe procedure for ACA500. Now the user just needs acafh0
compiled in his kernel and it all should(tm) work.

Due to lack of obio in amiga port, the probe is called directly from mbattach().
This is going to change with the introduction of obio for all non-autoconfig
expansions.

Add preliminary support for the Individual Computers ACA500 in the form of acahf
driver. If ACA500 is equipped with supported accelerator with MMU, it allows
running NetBSD on an Amiga 500.

Since ACA is not autoconf-aware, and the probe procedure does not exist yet, the
driver is activated with the ACA500_SUPPORT kernel option. The acahf driver
is commented out in the GENERIC kernel for now (at least until it stops being
very experimental and hackish).

When it comes to ACA-specific hardware, for now the boot CF slot works. Support for everything else is incoming...

Do not call setroot() from MD code and from MI code, which has

No longer wrap MD cpu_rootconf(), as hp300 port stores reboot information

rootconf() now a wrapper to setroot().

Adjust several MD routines to set the global booted_device,booted_partition
variables instead of passing partial information to setroot().

Make cpu_rootconf(9) describe the calling order.

Clean up p5pb console glue a bit.

Add clockport(4) layer, which provides support for expansion bus present on
Amiga-style clockports. Also add a1k2cp(4) backend driver and the first
clockport device driver com_ss, that supports com(4) on clockport(4)

fake up a dv_cfdriver entry before calling config_search().
config_search() does not do the lookup for us anymore.

Use aprint_normal() for cfprint routines.

Overhaul the way cfattach structures are looked up. The cfdata entry
now carries the name of the attachment (e.g. "tlp_pci" or "audio"),
and cfattach structures are registered at boot time on a per-driver
basis. The cfdriver and cfattach pointers are cached in the device
structure when attached.

Use CFATTACH_DECL().

Add a config_init() function to initialize the config data structures.
Normally this is called by configure(), but some ports (amiga, atari,
x68k) need to do this early because of how they find the console.

Declare all cfattach structures const.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

Initial revision

powerpc: Sprinkle "memory" clobbers on eieio and nearby asm blocks.

Otherwise the compiler may reorder these around loads and stores,
which mostly defeats the purpose. `asm volatile' just ensures the
instruction isn't _deleted_; it may still move around.

Xorg for amiga via wsfb. Currently available on CV64 and CV64/3D. More
graphics cards will follow, when adding wscons support to them.

I didn't manage to make the "wskbd" protocol the default in the X server,
so you have to provide a small xorg.conf with Option "Protocol" "wskbd".
The standard protocol will not work as the Amiga wskbd cannot be switched
into raw mode and has no AT-scancode translation in the kernel.

On the positive side, wskbd also works with national keymaps under X.

The graphics modes can still be defined via grfconfig(8). Xorg's wsfb
driver uses the current grf video mode, which is usually mode #1.
All resolutions and depths seem to work (tested on CV64).

Ugly hack to fix the builds.

Driver for the MNT ZZ9000 Zorro board. Submitted by Alain Runa.

It was formerly known as mntzz, which Alain released three years ago.
Since then, the ZZ9000 had several firmware updates which changed some
hardware interface details rendering the former driver non functional in some
aspects. Also the audio card plug-in ZZ9000AX became available from MNT
Research. Considering the major rewrite of the driver in some areas he
decided to rename it to zz9k(9). The driver consists of several sub-drivers
each addressing different functionality of the MNT ZZ9000 & ZZ9000AX combo
card.

zz9k* is the main card driver and need to be enabled if any of the sub-driver
is enabled. zz9k on its own is not very useful, it only provides a common
zz9kbus for the other sub-drivers to connect to, so only enable it if one of
the zz9k sub-drivers are enabled.
zzfb* represents the graphics driver for the boot console and the dumb
framebuffer for X11 based on WSCONS. ZZFB_CONSOLE option enables the ZZ9000
to become the boot console.
zz* represents the ethernet interface of the ZZ9000. It basically works but
is considered experimental.
zzax* represents the ZZ9000AX audio card driver, audio* attaches to it to
provide audio output and input functionality. The driver is not functional
yet.
zzusb* represents the ZZ9000AX usb driver. It was not implemented yet and
probably never will.

Add a driver for MNTMN VA2000.

Supports accelerated wsdisplay console and running X via wsfb driver.

branches: 1.73.6; 1.73.24; 1.73.28;
Amiga wscons/Xorg support, first phase.
Implemented wscons for CV64 and CV64/3D. Other graphics cards drivers are
prepared for it, but will not be attempted before Xorg is not running.
The wscons support is disabled by default. A GENERIC kernel should behave
like always. Use WSCONS to try out a kernel with wscons support.

now that mem_no is emitted by config(8), there is no reason to keep
copy of more or less identical iskmemdev() for every arch; move the function
to spec_vnop.c, and g/c machine-dependant copies

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

Rename cdev_systrace_init() to cdev_clonemisc_init(), so it can

Enable the imported ISDN4BSD based ISDN subsystem.

This is the kernel part (userland to follow soon) of the latest (and
very probably last) release (version 0.96) of ISDN4BSD. ISDN4BSD has a
homepage at http://www.freebsd-support.de/i4b/.

It gives the user various ways to use the isdn connection: raw data (via
the i4brbch "raw b-channel" device), ppp (via the isp "isdn PPP" device),
voice/answering machine (the i4btel "telephone" device) and ip over isdn
(the ipr device, "IP over raw ISDN").

Supported are a bunch of common and older cards, more to be added soon
