floppies must have been random in 2.x since we reintroduced sorting
on b_pblkno on 1995/03/18. Drivers still initialize b_cylin/b_resid
although this is no longer used.
Removed unused, wrong function fdsize(). (Returning 0 means that the
device exists and has size 0, not that the device doesn't exist.
swaponvp() allows for size 0 by stupidly calling the d_psize function
twice if the size isn't 0. setdumpdev() doesn't allow for it.)
Continued removing /* ARGSUSED */ from drivers.
introduced.
Fixed the device-driverness of atapi.c and spkr.c.
These changes are actually no-ops because ${DRIVER_C} is the same as
${NORMAL_C} for the i386. I could do without magic CFLAGS. Special
handling should be in the sources if possible.
boot to display "Booting the kernelel...done" instead of "Booting
the kernel".
Removed save and restore of BIOS memory. kzipped kernels haven't
ever overlaid the BIOS memory.

from a string to an identifier so that it can be used to generate
declarations and strings. It's much easier to stringize an identifier
than to identifize a string. A uniform naming scheme must be used
for the automatically generated things to apply. This is a feature.
Used the module identifer to generate prototypes for the module load,
unload and stat functions. Removed the few prototypes for these that
already existed.
Used the module identifier to generate a unique struct tag in MOD_DEV().
This should probably be done for all the MOD_*() macros.
Moved the trailing semicolon from the MOD_*() macro definitions to the
macro invocations that didn't already (bogusly) have it.
Staticized the module load and unload functions.
Added function return types for the module load, unload and stat functions.
lkm/ibcs2/ibcs2.c:
Included <sys/sysproto.h> to get everything prototyped.
Cleaned up #includes.
lkm/ibcs2/ipfw.c:
Cleaned up #includes.
lkm/linux/linux.c:
The module name had to change from "linux_emulator" to "linux_mod" to
be automatically generated.

lkm/syscons/*/*_saver.c:
Completed delcarations of function pointers.
sys/i386/isa/atapi.c:
The module name had to change from "atapi" to "atapi_mod" to be
automatically generated.
sys/i386/isa/wcd.c:
Used the fixed MOD_DEV(). This module has two devices and expanded the
macro in the source instead of fixing it.
The module names had to change from "wcd" and "rwcd" to "wcd_mod" and
"rwcd_mod" to be automatically generated.

The module name had to change from "pcic" to "pcic_mod" to be

much as I'd like to, but the malloc stunt I tried for an interim for
sure does worse.
Now we can read and write from any kind of address-space, not only
user and kernel, using callbacks.
This may be over-generalization for now, but it's actually simpler.
Included <sys/sysproto.h> to get central declarations for syscall args
structs and prototypes for syscalls.
Ifdefed duplicated decentralized declarations of args structs. It's
convenient to have this visible but they are hard to maintain. Some
are already different from the central declarations. 4.4lite2 puts
them in comments in the function headers but I wanted to avoid the
large changes for that.
- collapsed #if-#elses that became null.
- removed dead comments.
Moved #defines that always have the same value to the tables.
Collapsed more #if-#elses that became null. None are left.
Removed repetitive comments.
Most of this is cleaning up, but there are some functional changes,
doc/comment improvements, error checking, gcc -Wall cleanups. Input buffer
flushing is enabled now, although I'm still not quite certain it's right.
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.
Changed vnodep -> vp for consistency with the rest of the kernel, and
changed iparams -> imgp for brevity.
kern_exec.c:
Explicitly initialized some additional parts of the image_params struct
to avoid bzeroing it. Rewrote the set-id code to reduce the number of
logical tests. The rewrite exposed a mostly benign bug in the algorithm:
traced set-id images would get ktracing disabled even if the set-id didn't
happen for other reasons.
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.
These functions went away:
enosys (hasn't been used for some time)
enxio
enodev
enoioctl (was used only once, actually for a vop)
if_tun.c:
Continued cleaning up...
conf.h:
Probably fixed the type of d_reset_t. It is hard to tell the correct
type because there are no non-dummy device reset functions.
Removed last vestige of ambiguous sleep message strings.
Start the revamp of the initialiation process. New routines include
ahc_alloc, ahc_free, and ahc_reset. These help divide the work of staring
up a board more logically between probe and attach.
ahcintr now takes a (void *) and returns int. The pci code uses it directly.
Until the PCI code for shared edged triggered interrupts is removed, the
eisa code uses a stub (ahc_eisa_intr) that throws away the int returned
by ahcintr.
Use MHz instead of MB/s for printing out sync rates.
Print out "aic7880" instead of "aic7870" for the new aic7880 chips.
in here to do some conflict detection. The new code doesn't do conflict
detection yet, but it will be implemented in another way.
aic7770.c moved to i386/eisa
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.
/dev/random is now a part of the kernel! you will need to make
the device in /dev: sh MAKEDEV random
and take a look at some test code in src/tools/test/random.
incompatible with the type of a PCI interrupt handler. A new entry
point `ahc_pci_intr()' is used for PCI. ISA and PCI interrupts are
penalized equally (:-) by calling a common handler `ahc_intr()'. This
should be reorganized. Some strings now name the wrong function...
to <machine/conf.h>. conf.h was mechanically generated by
`grep ^d_ conf.c >conf.h'. This accounts for part of its ugliness. The
prototypes should be moved back to the driver sources when the functions
are staticalized.
the kernel. ppp_tty.c goes to some lengths to minimise the inter-layer
calling (including a soft ISR). ppp_tty.c takes care of the soft masking
that was needed still.
(I've discovered that bugs in this area show up within an hour if the
masking was not correct.. :-} This combination has proven stable on
specialix serial ports, although there was some concern about the softtty
parts of sio/cy and netisr colliding - but Bruce has fixed that now)

this driver hasn't been checked but as a separate module, bringing it in won't
break anything else and it't the best way of testing it......
julian
line discipline interrupt handlers more or less expect to be called at
spltty() == splimp(), although they have internal splimp()s that are
bogus if this expectation is satisfied. They are called at splsoftty()
from many tty drivers, so they were not protected from being reentered
from their own netisrs. They certainly don't expect that but are
apparently remarkably robust if it occurs. The problem in PR 798 seems
to be caused by pppstart() being reentered and finishing off the output
in progress by following the (stale) sc->sc_outm pointer. Then the
original pppstart() finds garbage in m2 after MFREE(m, m2). slstart()
doesn't have internal state like sc_outm so reentry of it probably only
causes out of order and dropped packets.
modularization of the wd/wcd/atapi driver is ugly.
Include cons.h from a less bogus place.
Removed an ARGSUSED. Unused args are normal for devswitch functions
and lint was informed about them for about 5 functions out of 1000.
Lint should be informed about them, if at all, in some other way.
Remove confusing backwards compatibility code that allowed driver to be
used in pre-4.4 releases. The 3COM card's use -link2 to switch tranceivers.
(no functional changes here)
This code will only be included in your kernel if you have
'options DEVRANDOM', but that will fall away in a couple of days.

related gunf that goes with it..
it is not guaranteed to work 100% correctly at this time
but as we had several people trying to work on it
I figured it would be better to get it checked in so
they could all get teh same thing to work on..

Fix the tests for being a console by reverting to the ones that
were used before the the RB_SERIAL changes. RB_SERIAL only needs
to be tested in one place. The initialization of comconsole was
wrong before the RB_SERIAL changes for the COMCONSOLE case. This
may have been the cause of the unnecessary changes.
Start eliminating #includes of <i386/i386/cons.h>. This header is
supposed to be included from <machine> although it should be
completely machine-independent and included from <sys>.
Remove a wrong XXX comment. `comconsole' is used to test for being
a console and even the tests for deciding the default termios state
are necessary (the semi-reentrant i/o routines don't handle ordinary
device i/o).
cy.c:
Sync with sio.c. The console tests are present but always fail.
handler (remove SA_NODEFER).
On the other hand, signal() case should set sa_flags to SA_NODEFER as
in previous change.
In addition, added #ifdef'd code for signal() to or in SA_RESETHAND
flag for when that compatability is implemented.
accesses after the BIOS bus scan. The previous revision made the assumption,
that every PCI motherboard did ...
Change the test on the initial value of the CONF1_ADDR_PORT register in a way
that makes the probe succeed on triton based motherboards, without breaking
the EISA motherboard that has some non-PCI register at the same address.
This is truly a hack. The idea is taken from the Linux ibcs2 emulator.
To use this feature, you must use the option,
options SPX_HACK
in your config.
Also, in /compat/ibcs2/dev, you must do:
lrwxr-xr-x 1 root wheel 9 Oct 15 22:20 X0R@ -> /dev/null
lrwxr-xr-x 1 root wheel 7 Oct 15 22:20 nfsd@ -> socksys
lrwxr-xr-x 1 root wheel 9 Oct 15 22:20 socksys@ -> /dev/null
crw-rw-rw- 1 root wheel 41, 1 Oct 15 22:14 spx
Do NOT use old socksys driver as that has been removed.
This hack needs /compat/ibcs2/dev/spx to be any device that does NOT
exist/configured (so the now non-existant spx major/minor works fine).
When an open() is called, the error ENXIO is checked and then the
path is checked. If spx open detected, then a unix socket is opened
to the hardcoded path "/tmp/.X11-unix/X0".
As the Linux hacker author mentioned, the real way would be to detect
the getmsg/putmsg through /dev/X0R and /dev/spx. Until this true
solution is implemented (if ever), I think this hack is important
enough to be put into the tree, even though I don't like it dirtying
up my clean code (which is what #ifdef SPX_HACK is for).
Currently, the emulator defaults to returning "FreeBSD" as the system
name, release "3.2", and version "2.0". Some programs want to make
sure they are on a SYSV 3.2 system and check for 3.X release number.
Use the following defines to override the defaults:
IBCS2_UNAME_SYSNAME
IBCS2_UNAME_RELEASE
IBCS2_UNAME_VERSION
(should be string)
for system name, release, and version, respectively. This allows
someone to compile the emulator into the kernel so it can pretend
to be a specific system if needed.
Require the state of the configuration enable bits to be OFF assuming
that the BIOS left them that way, as it should anyway to avoid bad things
to happen.
The tests themselves are copied from the previous release, with the
exception of CONF1_ENABLE_MSK1 having the LSB set. This bit should be
read back as '0', since only DWORD addresses are legal.
I tried to solve the problem of IDE probing compatibility in this version.
When compiled without an ATAPI option, the wd driver is
fully backward compatible with 2.0.5. With ATAPI option,
the wdprobe becomes strictly weaker. That is, if wdprobe works
without ATAPI option, it will always work with it too.
Another problem was with the CD-ROM drive attached as a slave
in the IDE bus, where there is no master. All IDE CD-ROM
drives are shipped in slave configuration, and most users
just plug them in, never thinking about jumpers.
It works fine with ms-dos and ms-windows, and this
version of the driver supports it as well.
The eject op can now load disks. Just repeat it twice,
and the disk will be ejected and then loaded back.
The disc cannot be ejected if it is mounted.
