I spent the better part of a day trying to figure out why my
experiment didn't work the way I expected, only to find out that
the router was dropping huge numbers of packets because of PCI bus
priblems. This does not fix the bug that errors are counted as
input packets because my patch doesn't apply cleanly.
is enabled by having an "device ed0 at isa? [...]" config line.
The first PCI card will get a unit number one higher than the highest
defined for any ISA card of the ED type, e.g. if ed0 and ed1 are
configured, then the PCI cards will be ed2, ed3, ...
BEWARE: If you have configured your kernel as ed0 with the port address
as assigned by the PCI BIOS, then your card will be found by both the
PCI and ISA probes, and bad things may happen. Make sure to restore
the original port address form the GENERIC kernel for the ed0 device!

a BIOS was not installed, this will still be true by the time we probe
the chip. We use this heuristic to determine if we should use the left
over scratch ram target settings for controllers that don't have an
SEEPROM. We also "snapshot" the host adapter SCSI id and whether ultra
is enabled or not and use these values if a BIOS was installed. The card
will act as if a BIOS was installed even if there wasn't one if you warm
reboot, but since the scratch ram area is still valid in this case, its
hardly worth the effort of writing a shutdown routing that clears out
the scratch ram. This should make users of motherboard controllers
happy.

They are both true if the bridge is not cascaded (i.e., twin-channel
scsi/e-net adapters won't be affected by this bug), which is probably why
it was unnoticed until today.
- always use pci_conf_read() and pci_conf_write(). (This is required to
simulate non-existant devices in my system for PCI bridge code tests.)
- reorder some functions (put the main functions at the end).
- correct off by one bug in the code dealing with unitialized PCI to PCI
bridge chips. (Bug found by ASAMI Satoshi.)
- print function number for multi-function devices.
Use new XS_SELTIMEOUT error code for selection timeouts.
aic7870.c:
Move SCB walking code to aic7xxx.c and make it work for all card types.
The flag AHC_EXTSCB is no longer needed since the SCBs are walked in
all cases now.
vm_offset_t is currently unsigned long but should probably be plain
unsigned for i386's to match the choice of minimal types to represent
for fixed-width types in Lite2. Anyway, it shouldn't be assumed
to be unsigned long.
I only fixed the type mismatches that were detected when I changed
vm_offset_t to unsigned. Only pointer type mismatches were detected.

- Probe only 1 LUN

Defining FAILSAFE will result in a driver that will tolerate

It is intended for use in install kernels.
Cleanse the SCSI subsystem of its internally defined types

Use the system defined *_t types instead.

port addresses (even though the PC architecture doesn't support them).
Add code to limit the I/O map size based on the lowest set bit of the
address. This cures the problem with the BT946C only having a 16 bit
map register, in voiolation of the PCI specs, without giving up the
general support of >65K port regions.

SCSI_NCR_DFLT_TAGS can be specified in the kernel config file

This should correctly probe both functions of the Intel 82371FB chip,

actual interface from the wd driver to the new facility is not
implemented yet (this commit being an attempt at prodding someone else
to do it because looking at the wd driver always confuses the h*** out of me).
includes a hack in the probe code: the 82371FB is a multifuction
device, but doesn't properly set the configuration bit which
indicates this. So, we just hard-wire all 82371FBs as multifunction
devices.
This does not actually make the bus-master IDE stuff work, although
if anyone wants to work on that, I have the databooks that tell
how to use it.
(To be replaced by sysctl accesses some time ...)
Remove a backward jump from the NCR script, which allowed a SCSI target
to receive any number of NOP messages it desired. If a target indeed
does such a silly thing, make it fail at the next instruction, instead
of causing a timeout a few seconds later.
Simplify the initialization of adapters by pulling all card specific

Set the Latency timer and Burst len to good values if thery are not
initialized during post or are reset during chip reset.
Properly identify and handle external SCB SRAM. The code was false

pci now uses a different interrupt handler type for interrupts that it
dispatches and the isa interrupt handler type for the interrupts that
it handles.
Reduce default value of pcicb_membase to 0x2000000 (from 0x4000000)

all the other bt_XXX() functions in i386/scsi/bt*.
This the important effect of forcing a link error if the user is
still using the old "vector btintr" which is dangerously wrong
after Justin's updates to the driver.
The correct isa vector line for the bt driver is "vector bt_isa_intr".
Justin mentioned this in the commit message and updated LINT and
GENERIC. This change is to enforce that.. :-)
most devsw referenced functions are now static, as they are
in the same file as their devsw structure. I've also added DEVFS
support for nearly every device in the system, however
many of the devices have 'incorrect' names under DEVFS
because I couldn't quickly work out the correct naming conventions.
(but devfs won't be coming on line for a month or so anyhow so that doesn't
matter)
If you "OWN" a device which would normally have an entry in /dev
then search for the devfs_add_devsw() entries and munge to make them right..
check out similar devices to see what I might have done in them in you

for a laugh compare conf.c conf.h defore and after... :)
I have not doen DEVFS entries for any DISKSLICE devices yet as that will be
a much more complicated job.. (pass 5 :)
pass 4 will be to make the devsw tables of type (cdevsw * )

Removed ifnet.if_init and ifnet.if_reset as they are generally unused.
Change the parameter passed to if_watchdog to be a ifnet * rather than
a unit number. All of this is an attempt to move toward not needing an
array of softc pointers (which is usually static in size) to point to
the driver softc.
if_ed.c:
Changed some of the argument passing to some functions to make a little
more sense.
if_ep.c, if_vx.c:
Killed completely bogus use of if_timer. It was being set in such a way
that the interface was being reset once per second (blech!).
o Add signed/unsigned functionality to the matrox meteor device driver.
o Apply a few fixes to the sound driver.
o Add a ``SPIGOT_UNSECURE'' compile time definition so, if one defines
SPIGOT_UNSECURE in their conf file, then they can use the spigot w/o
root. There is a warning that this allows users access to the IO
page which is probably not secure.

Convert the remaining sysctl stuff to the new way of doing things.
the devconf stuff is the reason for the large number of files.
Cleaned up some compiler warnings while I were there.
