Cleanse the SCSI subsystem of its internally defined types
u_int32, u_int16, u_int8, int32, int16, int8.
Use the system defined *_t types instead.
eisaconf.c:
Cosmetic formatting chagnes.
The eisaconf probe for the 3Com 3c579 and the 3c509 when in eisa
configuration mode.
aha1742.c aic7770.c bt74x.c:
Only call eisa_registerdev after the probe is successfully.
eisaconf.c:
Increase kdc->kdc_datalen during the eisa_reg* functions instead of
in the eisa_add* functions since eisa_registerdev has already been
called and we have a kdc to manipulate.
- Call eisa_registerdev as soon as we have a device match. This allows the
"eisa_add_*" routines to tweak kdc_datalen as the kdc grows and shrinks.
eisaconf.c
- externalize the linked lists that hold our ioaddrs and maddrs.
this driver no longer needs to maintain an array of configured units.
Pass "softc" pointers instead of unit numbers to many functions that
did a conversion for unit->softc anyway.
aic7770.c:
Simplify the initialization of adapters by pulling all card specific
initialization to the card specific modules.
eisaconf.c:
outb 0x80 instead of 0xc80. The top byte is truncated anyway, and 0x80
was what was intended.
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.. :-)
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.
Handle kdc registration correctly. Catch ISA devices that use eisa
registration and output probe information accordingly.
lsdev will have to be updated to handle EISA devices correctly.
aic7770.c:
Set kdc_isa0 as the parent for 284X cards since its a VL card.
cards like the Adaptec 284x that use EISA ID registers for identification
even when in stalled in non-EISA systems.
Use one format throught the files.
-Wall fixes.
be the beginning of our move to a more dynamic (configuration manager)
based setup for all drivers. Everything seems to work except for
some devconf problems. Only the aic7xxx driver will be using this
interface until it is reviewed, revised and accepted as a good configuration
interface.
Adapt aic7770.c to use new eisaconf.
eisadevs.c is replaced by a linker set.
misplaced extern declarations (mostly prototypes of interrupt handlers)
that this exposed. The prototypes should be moved back to the driver
sources when the functions are staticalized.
Added idempotency guards to <machine/conf.h>. "ioconf.h" can't be
included when building LKMs so define a wart in bsd.kmod.mk to help
guard against including it.
This change forces the controller drivers to allocate a scsibus_data struct
via a call to scsi_alloc_bus(), fill in the adapter_link field, and optionally
modify any other fields of the struct. Scsi_alloc_bus() initializes all fields
to the default, so the changes in most drivers are very minimal. For drivers
that support Wide controllers, the maxtarg field will have to be updated to
allow probing of all targets (for an example, look at the aic7xxx driver).
Scsi_attachdevs() now takes a scsibus_data* as its argument instead of an
sc_link*. This allows us to expand the role of the scsibus_data struct for
other bus level configuration setings (max number of transactions, current
transaction opennings, etc for better tagged queuing support).

Declare `cheat' as static. It was bogusly shared between the aha1742 and
ultrastor drivers.
Even static variables should have unique names so that they can be
debugged, but fixing them can wait.
optimizations I have been working on yet, but does bring in some bug fixes
and performance improvments that were easy to regression test:
Setup the data fifo threshold and bus off timing correctly for 27/284x cards.
Users of these adapters with fast periferals (greater than 5MB/s) will notice
a big performance difference. (Sometimes as large as going from 3.7->8.3MB/s).
Fix handling of the active target flags. Some of the outbs where missing
the base offset in the abort code. The abort code still needs lots of work.
Support 3940 controllers, but only with 16 SCBs for now. Eventually I'll
add support for all 255, but I need to find a tester for the code first since
we have to enable the cards external SRAM to do this.
Add Dan Eischen's serial eeprom reading facilities. This allows the 2940
adapters to pull additional information left over from SCSI-Select right out
out of the configuration seeprom.
If the BIOS is disabled on 274x controllers, reset all target parameters
to there defaults since you can't rely on what is stored in scratch ram.
Report motherboard controllers as such.
Stick the first SG address and count into the SCB data and count areas for
all transfers in preparation of a later sequencer optimization.
Keep track of which targets can are allowed to have the disconnection
priveledge since this will be handled by the kernel driver in the future.
If a target issues a message reject in response to a tagged message,
disable tagged queuing for that target. Some seagates say they can do
tagged queuing, but lie, and its a shame to have to disable tagged queuing
on all devices just because you have one that can't cope.
don't expect this to work yet.. but at least they're here..
(hey this cvs stuff is fun!)
activate with a line exactly like the isa line in the config file,

patches to come..
For those where it was easy, drivers were also fixed to call
dev_attach() during probe rather than attach (in keeping with the
new design articulated in a mail message five months ago). For
a few that were really easy, correct state tracking was added as well.
The `fd' driver was fixed to correctly fill in the description.
The CPU identify code was fixed to attach a `cpu' device. The code
was also massively reordered to fill in cpu_model with somethingremotely
resembling what identifycpu() prints out. A few bytes saved by using
%b to format the features list rather than lots of ifs.
ultra14f.c and eliminate constants.
Correct EISA slot scan loops to look at slots 1 to 15 inclusive (off
by 1 errors all over the place). Other drivers need this, I will get
to it after a little more work.
Correct the ultrastore EISA probe so that it starts after the last
EISA slot probed instead of starting over from slot 0.
We need an eisa.h to move a lot of common constants into. I will
write it if someone tells me where it should go (sys/eisa?).
#include <i386/isa/isa.h>
return IO_EISASIZE instead of hard coded 0x1000.
if_ep.c:
Remove commented out disabling of interrupts that gave a
"comment withing a comment" warning.
