The code for suspend/resume is derived from APM device driver.
Some people suggested the original code is somewhat buggy, but I'd
like to just move it from apm.c without any major changes for the
initial version. This code should be refined later.
To use pmtimer to adjust time at resume time, add
device pmtimer
in your kernel config file, and add
hint.pmtimer.0.at="isa"
in your device.hints

include:
* Mutual exclusion is used instead of spl*(). See mutex(9). (Note: The
alpha port is still in transition and currently uses both.)
* Per-CPU idle processes.
* Interrupts are run in their own separate kernel threads and can be
preempted (i386 only).

Use Warner Losh's "hint" driver to decode ascii strings to fill the
resource table at boot time.
config(8) no longer generates an ioconf.c table - ie: the configuration
no longer has to be compiled into the kernel. You can reconfigure your
isa devices with the likes of this at loader(8) time:
set hint.ed.0.port=0x320
userconfig will be rewritten to use this style interface one day and will
move to /boot/userconfig.4th or something like that.
It is still possible to statically compile in a set of hints into a kernel
if you do not wish to use loader(8). See the "hints" directive in GENERIC
as an example.
All device wiring has been moved out of config(8). There is a set of
helper scripts (see i386/conf/gethints.pl, and the same for alpha and pc98)
that extract the 'at isa? port foo irq bar' from the old files and produces
a hints file. If you install this file as /boot/device.hints (and update
/boot/defaults/loader.conf - You can do a build/install in sys/boot) then
loader will load it automatically for you. You can also compile in the
hints directly with: hints "device.hints" as well.
There are a few things that I'm not too happy with yet. Under this scheme,
things like LINT would no longer be useful as "documentation" of settings.
I have renamed this file to 'NOTES' and stored the example hints strings
in it. However... this is not something that config(8) understands, so
there is a script that extracts the build-specific data from the
documentation file (NOTES) to produce a LINT that can be config'ed and
built. A stack of man4 pages will need updating. :-/
Also, since there is no longer a difference between 'device' and
'pseudo-device' I collapsed the two together, and the resulting 'device'
takes a 'number of units' for devices that still have it statically
allocated. eg: 'device fe 4' will compile the fe driver with NFE set
to 4. You can then set hints for 4 units (0 - 3). Also note that
'device fe0' will be interpreted as "zero units of 'fe'" which would be
bad, so there is a config warning for this. This is only needed for
old drivers that still have static limits on numbers of units.
All the statically limited drivers that I could find were marked.
Please exercise EXTREME CAUTION when transitioning!

2. Newbusify the driver.
3. Build as a module.
4. Use correct minor numbers when creating device files.
5. Correctly lock control characters.
6. Return ENXIO when device not configured.

Note:
- the old driver still lives in src/sys/i386/isa, so that you can
revert to it if something goes wrong.
- The module does not detach very well. Attaching works fine.
config(8). This commit allows control of the creation of the
#include "foo.h" files. We now only create them explicitly when needed.
BTW; these are mostly bad because they usually imply static limits on
numbers of units for devices. eg: struct mysoftc sc[NFOO];
These static limits have Got To Go.
Symbol values are now represented using array sizes (4 arrays per symbol
so that 16-bit machines can represent 64-bit values) instead of being raw
binary values.

- Move dev/aic/aic_isa.c entry from conf/files to conf/files.MACHINE
because PC-98 uses different file.

it's options COMPAT_OLDISA and COMPAT_OLDPCI. This is meant to be a
fairly strong incentive to update the older drivers to newbus, but doesn't
(quite) leave anybody hanging with no hardware support. I was talking with
a few folks and I was encouraged to simply break or disable the shims but
that was a bit too drastic for my liking.
Enable the driver in sys/conf/files.i386.
In isa/isavar.h increase ISA_NPORT from 32 to 50. This is required
because this brain-damaged card maps 49 (!) port ranges. This does
not have a negative impact because this value only specifies the maximum
number of entries in a linked list and not the size of an array which
is allocated in all drivers.
The register/fifo access routines were not newbus-ified because
1) I knew that the old code worked and is simpler and more efficient
2) the if_ed driver does something similar and
3) the newbus macros collapse to inb/outb anyway.

wcd.[ch], but there's already one of those in the Attic that we can't
clobber - the good names are taken.
Fix building so that it can be compiled into LINT alongside ata.

- Split terminal emulation code from the main part of the driver so
that we can have alternative terminal emulator modules if we like in
the future. (We are not quite there yet, though.)
- Put sysmouse related code in a separate file, thus, simplifying the
main part of the driver.
As some files are added to the source tree, you need to run config(8)
before you compile a new kernel next time.
You shouldn't see any functional change by this commit; this is only
internal code reorganization.
Collect together the components of several drivers and export eisa from
the i386-only area (It's not, it's on some alphas too). The code hasn't
been updated to work on the Alpha yet, but that can come later.
Repository copies were done a while ago.
Moving these now keeps them in consistant place across the 4.x series
as the newbusification progresses.

Driver is not functional yet, but does compile. Tests with xe cards
indicates that it doesn't panic the machine when they are present, but
fail to probe. Interface help in the pcic/pccard layers are needed to
complete this driver.
-U_KERNEL became negative when all all the genassym.c's were converted
to be cross-built. Related cleanups: PARAM went away, but was still
used here; KERNEL was renamed to _KERNEL, but was still KERNEL here;
the deprecated macros $@ and $< were still used here.
Use "genassym ... > ${.TARGET}", not "genassym -o $@ ...", so that
genassym(1) doesn't need to support -o.
Removed half-baked hard-coded dependencies of *_genassym.o on headers.
These objects should be added to the list of objects in the depend
rule to get full dependencies. This doesn't happen automatically
because they are not linked into the kernel. Half baked dependencies
don't really help.
These drivers were cloned from the ed and ep drivers back in 1994
when PCMCIA cards were a very new thing and we had no other support
for such devices. They treated the PCIC (the chip which controls the
PCCARD slot) as part of their device and generally hacked their way
to success. They have significantly bit-rotted relative to their
ancestor drivers (ed & ep) and they were a dead-end on the evolution
path to proper PCCARD support in FreeBSD.
They have been terminally broken since August 18 where mdodd forgot
them and nobody seems to have missed them enough to fix them since.
I found no outstanding PRs against these drivers.

- Convert to new bus attachment scheme. Thanks to Blaz Zupan for doing
the initial work here. One thing I changed was to have the attach
and detach routines work like the PCI drivers, which means that in
theory you should be able to load and unload the driver like the PCI
NIC drivers, however the pccard support for this hasn't settled down
yet so it doesn't quite work. Once the pccard work is done, I'll have
to revisit this.
- Add device wi0 to PCCARD. If we're lucky, people should be able to
install via their WaveLAN cards now.
- Add support for signal strength caching. The wicontrol utility has
also been updated to allow zeroing and displaying the signal strength
cache.
- Add a /sys/modules/wi directory and fix a Makefile to builf if_wi.ko.
Currently this module is only built for the i386 platform, though once
the pccard stuff is done it should be able to work on the alpha too.
(Theoretically you should be able to plug one of the WaveLAN/IEEE ISA
cards into an alpha with an ISA slot, but we'll see how that turns out.
- Update LINT to use only device wi0. There is no true ISA version of
the WaveLAN/IEEE so we'll never use an ISA attachment.
- Update files.i386 so that if_wi is dependent on card.
Semiconductor CS461x/428x.
- Add support for GUS and CS461x/428x pcm.
- Move newpcm drivers for ISA cards to files.i386. The drivers for
PC98 would be something quite different from those for PC/AT.
