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.
1) Use cpp to preprocess the sequencer code.
2) Convert all "magic numbers" to #defines shared by the sequencer and
kernel driver via the aic7xxx_reg.h file. (The assembler still needs
to be re-written in lex/yacc to allow ~|& type constructions).
3) Raise ATN on parity errors for "in" phases and send an initiator detected
error or message-in parity error message as appropriate.
4) Turn off the reselection hardware from the time or a (re)connection to
busfree. It seems that some fast targets were able to reconnect before
the sequencer was able to see busfree.
5) The message buffer is considered "in-use" when there is a positive length
count. The ACTIVE_MSG flag was unnecesary.
6) Properly set SCB_NEXT_WAITING to SCB_LIST_HEAD in scbs being added to
the waiting scb list. This is a change in how the list code works to
facilitate some planned work in the reset code.
7) The fields in the SCB have be re-arranged to be quad-word aligned.
8) The inb code has been rewritten to catch phasemisses and be more efficient.
9) Go back to "snooping the bus" to determine if the incomming identify
message will be followed by a simple queue message. Its much faster than
doing a search through the SCBs.
10) Implement better tag range checking for incomming tags.
11) Make sdtr_to_rate more accurate (use 25 instead of 24 in calculations -
must have been asleep that night).
12) Rearrange some routines to reduce code complexity and size.
13) Update comments and formatting.
14) Fixed bugs I've forgotten about??

Fixed the modes of the cua devices. It isn't possible to set the uid

Register the devswitch at device attach time. SYSINIT() is not
the right way to initialize devswitches (if anything :->).
Eventually, the devswitch should be deregistered at device detach
and/or unload time and reregistered at device attach time ... Then
some com->gone tests could be removed.
Cleaned up some other recent changes.

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.

getmajorbyname() which were a better (sigh) temporary interface to
the going-away devswitches.
Note that SYSINIT()s to initialize the devswitches would be fatal
in syscons.c and pcvt_drv.c (and are bogus elsewhere) because they
get called independently of whether the device is attached; thus
devices that share a major clobber each other's devswitch entries
until the last one wins.
conf.c:
Removed stale #includes and comments.
seems to work hre just fine though I can't check every file
that changed due to limmited h/w, however I've checked enught to be petty
happy withe hte code..
WARNING... struct lkm[mumble] has changed
so it might be an idea to recompile any lkm related programs
device must be configured. It's hard to tell whether a reset function
should be noreset or nullreset since reset functions are never called.
Most drivers use nullreset but noreset has the advantage of complaining
if somehow gets called).
Removed old aliases d_rdwr_t and d_ttycv_t for d_read_t/d_write_t and
d_devtotty_t.
Sorted declarations of switch functions into switch order.
Removed duplicated comments and declarations of nonexistent switch
functions.
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
can't see what's going on..
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 * )
rather than (cdevsw)

a deeply nested include.
Added nearby #includes of <sys/conf.h> where appropriate.
Fixed two cases of "=" that should have been "==" in card type comparison.
Simplified expression that checks for interface up/down.
Moved ed_ring_copy to before its first use so that it's inlined as intended.
Change mbuf allocation policy so that a received packet is stored in just
an mbuf header (no cluster) if it will fit in one.
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!).
conflicted with S3 graphics cards. Now users should put sio[2-3]
in the config file if the hardware exisst, even if the probe is
certain to fail due to an interrupt conflict. Otherwise, ports
sharing the interrupt may fail the probe if the system is warm
booted while sio[2-3] are active (perhaps under another OS). The
same problem for nonstandard ports is now handled better than
before.
That's EVERY SINGLE driver that has an entry in conf.c..
my next trick will be to define cdevsw[] and bdevsw[]
as empty arrays and remove all those DAMNED defines as well..
Each of these drivers has a SYSINIT linker set entry
that comes in very early.. and asks teh driver to add it's own
entry to the two devsw[] tables.
some slight reworking of the commits from yesterday (added the SYSINIT
stuff and some usually wrong but token DEVFS entries to all these
devices.
BTW does anyone know where the 'ata' entries in conf.c actually reside?
seems we don't actually have a 'ataopen() etc...
If you want to add a new device in conf.c
please make sure I know
so I can keep it up to date too..
as before, this is all dependent on #if defined(JREMOD)
(and #ifdef DEVFS in parts)
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.

totally dynamic.
this is only the devices in i386/isa
I'll do more tomorrow.
they're completely masked by #ifdef JREMOD at this stage...
the eventual aim is that every driver will do a SYSINIT
at startup BEFORE the probes, which will effectively
link it into the devsw tables etc.
If I'd thought about it more I'd have put that in in this set (damn)
The ioconf lines generated by config will also end up in the
device's own scope as well, so ioconf.c will eventually be gutted
the SYSINIT call to the driver will include a phase where the
driver links it's ioconf line into a chain of such. when this phase is done
then the user can modify them with the boot: -c
config menu if he wants, just like now..
config will put the config lines out in the .h file
(e.g. in aha.h will be the addresses for the aha driver to look.)
as I said this is a very small first step..
the aim of THIS set of edits is to not have to edit conf.c at all when
adding a new device.. the tabe will be a simple skeleton..
when this is done, it will allow other changes to be made,
all teh time still having a fully working kernel tree,
but the logical outcome is the complete REMOVAL of the devsw tables.
By the end of this, linked in drivers will be exactly the same as
run-time loaded drivers, except they JUST HAPPEN to already be linked
and present at startup..
the SYSINIT calls will be the equivalent of the "init" call
made to a newly loaded driver in every respect.
For this edit,

Line speeds of up to 2Mbps is possible. At this speed about 85% of the
bandwidth is usable with 486DX processors.
The standard FreeBSD sppp code is used for the link level layer. The
default protocol used is PPP. The Cisco HDLC protocol can be used by
adding "link2" to the ifconfig line in /etc/sysconfig or where ever
ifconfig is run.
At the moment only the V.35 and X.21 interfaces is supported. The others
may need tweaks to the clock selection code.

floppies must have been random in 2.x since we reintroduced sorting

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.
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.
