use of timeout_t -> timeout_func_t in aha1542 and aha1742 drivers.
2) fix a bug in the portalfs that was uncovered by better prototyping -
specifically, the time must be converted from timeval to timespec
before storing in va_atime.
3) fixed/added some miscellaneous prototypes
into one, hopefully functioning, Ultrastore driver. Any Ultrastore owners
out there - please speak up! We need to test this puppy.

This is the slowest and most stupid of our SCSI-drivers, but it is there
and it works. It has been tested with CD-ROM and disk.
It uses no interrupts, no DMA, just polled I/0.
Transfer-rate is <= 100Kbyte/sec.
If you set the jumpers on the board, you can change the unit-number and
you will be able to have four of these co-exist in one computer, why one
would do that is somewhat unclear though.
If I ever get my hand on the docs for this, I will improve it of course,
but for now we can install and access those CD-ROMs.
- Delete redundant declarations.
- Add -Wredundant-declarations to Makefile.i386 so they don't come back.
- Delete sloppy COMMON-style declarations of uninitialized data in
header files.
- Add a few prototypes.
- Clean up warnings resulting from the above.
NB: ioconf.c will still generate a redundant-declaration warning, which
is unavoidable unless somebody volunteers to make `config' smarter.
/usr/src/sys/i386/isa/clock.c:
o Garrett's statclock changes.
o Wire xxxintr, not Vclk.
o Wire using register_intr(), not setidt().
/usr/src/sys/i386/isa/icu.s:
o Garrett's statclock changes.
o Removed unused variable high_imask.
o Fake int 8 for rtc as well as int 0 for clk. Required for kernel
profiling with statclock, harmless otherwise.
/usr/src/sys/i386/isa/isa.c:
o Allow isdp->id_irq and other things in *isdp to be changed by
probes. Changing interrupts later requires direct calls to
register_intr() and unregister_intr() and more care.
ALLOW_CONFLICT_* is brought over from 1.1.5, except
ALLOW_CONFLICT_IRQ is not supported. IRQ conflict checking is
delayed until after probing so that drivers can change the IRQ
to a free one; real conflicts require more cooperation between
drivers to handle.
o Too many details to list.
o This file requires splitting and a lot more work.
/usr/src/sys/i386/isa/isa_device.h:
o Declare more things more completely.
/usr/src/sys/i386/isa/sio.c:
o Prepare to register interrupt handlers as fast.
/usr/src/sys/i386/isa/vector.s:
o Generate entry code for 16 fast interrupt handlers and 16 normal
interrupt handlers. Changed some constants to variables:
# $unit is now intr_unit[intr]. Type is int. Someday it should
be a cookie suitable for the handler (e.g., a struct com_s for
sio).
# $handler is now intr_handler[intr].
# intrcnt_actv[id_num] is now *intr_countp[intr]. The indirection
is required to get a contiguous range of counters for vmstat
and so that the drivers depend more in the driver than on the
interrupt number (drivers could take turns using an interrupt
and the counts would remain correct). There is a separate
counter for each device and for each stray interrupt. In
1.1.5, stray interrupt 7 clobbers the count for device 7 or
something worse if there is no device 7 :-(.
# mask is now intr_mask[intr] (was already indirect).
o Entry points are now _XintrI and _XfastintrI (I = intr = 0-15),
not _VdevU (U = unit).
o Removed BUILD_VECTORS stuff. There's a trace of it left for
the string table for vmstat but config now generates the
string in one piece because nothing more is required.
o Removed old handling of stray interrupts and older comments
about it.

not provide the full accuracy of a randomized statistical clock, it does
provide greater accuracy than the previous method, while not significantly
increasing overhead. It also provides profiling support at 1024 Hz.
You must re-compile config before making a new kernel, or you will end
up with unresolved symbols.
Reviewed uy: Bruce evans said it worked for him.
Added code to check for an adaptec 1542B Version 3.20 Board. This was the
first board that supports >1Gb drives and has the extended bios. So we
need also to disable the exbios like it is done for the 1542C/CF boards.
``changes'' are actually not changes at all, but CVS sometimes has trouble
telling the difference.
This also includes support for second-directory compiles. This is not
quite complete yet, as `config' doesn't yet do the right thing. You can
still make it work trivially, however, by doing the following:
rm /sys/compile
mkdir /usr/obj/sys/compile
ln -s M-. /sys/compile
cd /sys/i386/conf
config MYKERNEL
cd ../../compile/MYKERNEL
ln -s /sys @
rm machine
ln -s @/i386/include machine
make depend
make
Added my if_lp TCP/IP driver to lpt.c.
I have (surprise) not been able to test it on a 2.0 machine yet. Connect the
machines with a parallel "lap-link" cable, and get rates from 35 kbyte/sec
up to 75 kbyte/sec. (when ftp'ing foo: dev/zero -> bar:/dev/null).
The same lpt.c file should compile under 1.1.5.1 without problems.
I think we should promote this feature when we dump 2.0 on the expectant
public, because it provides a cheap and efficient way to move data to and
from notebooks &c. It is not a replacement for ethernet, but a cheap
substitute sometimes.
This driver supports all the DEC EtherWORKS III NICs (DE203, DE204,
and DE205) and the later DEC EtherWORKS II NICs (DE200, DE201, DE202,
DE422). DEPCA-style boards prior to the DE200 have not been tested
and may not work.

Reduced maximum transfer size by one to allow for catching a too large
condition correctly. Do single block I/O if the size is too large.

based originally on work by David Greenman and adapted to FreeBSD
(and cleaned up a bit) by myself. It supports the IBM Credit Card
Adapter for the IBM Thinkpad, and I've had no trouble making it work
on my Toshiba T1910 with a National `InfoMover' NE4100 PCMCIA ethernet
card (I'm commiting this message through it right now :-).
This is actually sneaking it in after feature-freeze, but it's just
too useful to pass up! As always, necessity is a mother.
change all of these to be timeout_funt_t and remove the casts and
typedef?
Remove secound argument (uban) from ifp->if_reset routines since it is now
obsolete.

Do a board reset if the AHA_INQUIRE command fails. This is needed for the
DTC3290. Change the messages about the BT545 to be generic to non adaptec
boards, since it appears that most vendors do not implement the AHA_INQUIRE
command in thier compatibility mode.
