bd7e5f992e Eliminated many redundant vm_map_lookup operations for vm_mmap.
Speed up for vfs_bio -- addition of a routine bqrelse to greatly diminish
	overhead for merged cache.
Efficiency improvement for vfs_cluster.  It used to do alot of redundant
	calls to cluster_rbuild.
Correct the ordering for vrele of .text and release of credentials.
Use the selective tlb update for 486/586/P6.
Numerous fixes to the size of objects allocated for files.  Additionally,
	fixes in the various pagers.
Fixes for proper positioning of vnode_pager_setsize in msdosfs and ext2fs.
Fixes in the swap pager for exhausted resources.  The pageout code
	will not as readily thrash.
Change the page queue flags (PG_ACTIVE, PG_INACTIVE, PG_FREE, PG_CACHE) into
	page queue indices (PQ_ACTIVE, PQ_INACTIVE, PQ_FREE, PQ_CACHE),
	thereby improving efficiency of several routines.
Eliminate even more unnecessary vm_page_protect operations.
Significantly speed up process forks.
Make vm_object_page_clean more efficient, thereby eliminating the pause
	that happens every 30seconds.
Make sequential clustered writes B_ASYNC instead of B_DELWRI even in the
	case of filesystems mounted async.
Fix a panic with busy pages when write clustering is done for non-VMIO
	buffers.

791d77e0dd Get rid of two and a half printf in the kernel.
Add more features to the one remaining to handle the job:
	+	signed quantity.
	#	alternate format
	-	left padding
	*	read width as next arg.
	n	numeric in (argument specified) default radix.

Fix the DDB debugger to use these.
Use vprintf in debug routine in pcvt.

The warnings from gcc may become more wrong and  intolerable because
of this.

Warning:  I have not checked the entire source for unsupported or
changed constructs, but generally belive that there are only a few.

0c83bb499c Add NMSS to the list of things that local.h checks for when decding
whether of not to automatically #define EXCLUDE_AUDIO; MSS is a real
audio device and we should not #define EXCLUDE_AUDIO if we have one.
(And I want it because it's the only mixer-capable audio driver that I
can use with my crummy Packard Bell (nee Aztech) audio board.)

This fixes the very confusing condition where having all of this:

mss0 at 0x530 irq 10 drq 1 on isa
gus0: <MS Sound System (CS4231)>
opl0 at 0x388 on isa
opl0: <Yamaha OPL-3 FM>
mpu0 at 0x300 irq 9 drq 0 on isa
mpu0: <MPU-401 MIDI Interface 0.0 >

will still give you this:

% cat /dev/sndstat
SoundCard Error: The soundcard system has not been configured

Also remove an unnecessary newline in the printf() message for the
'gus0' device shown above so that we don't wind up printing a blank
line between mss0 and gus0.

d4fb926c62 Finally demolished the last, tottering remnants of GATEWAY. If you want
to enable IP forwarding, use sysctl(8).  Also did the same for IPX,
which involved inventing a completely new MIB from whole cloth (which
I may not quite have correct); be aware of this if you use IPX forwarding.

Simplify the initialization of adapters by pulling all card specific

Update comments and fix formating.

Pass struct ahc_data*'s to functions instead of unit numbers.

Take advantage of the quad word alignment of SCB fields.

Adapt to new sequencer changes:

	2) Fill the message buffer as appropriate during a parity error.

	3) Count all of the SGs involved in a residual instead of just

912e603778 Implemented non-statistical kernel profiling. This is based on
looking at a high resolution clock for each of the following events:
function call, function return, interrupt entry, interrupt exit,
and interesting branches.  The differences between the times of
these events are added at appropriate places in a ordinary histogram
(as if very fast statistical profiling sampled the pc at those
places) so that ordinary gprof can be used to analyze the times.

gmon.h:
Histogram counters need to be 4 bytes for microsecond resolutions.
They will need to be larger for the 586 clock.
The comments were vax-centric and wrong even on vaxes.  Does anyone
disagree?

gprof4.c:
The standard gprof should support counters of all integral sizes
and the size of the counter should be in the gmon header.  This
hack will do until then.  (Use gprof4 -u to examine the results
of non-statistical profiling.)

config/*:
Non-statistical profiling is configured with `config -pp'.
`config -p' still gives ordinary profiling.

kgmon/*:
Non-statistical profiling is enabled with `kgmon -B'.  `kgmon -b'
still enables ordinary profiling (and distables non-statistical
profiling) if non-statistical profiling is configured.

13b6889458 Add the attempted DMA address to the 'DMA beyond end of ISA' message so that
we can see if it's a small distance beyond the end, or way out. This may
give some clues as to whether it is being caused by something coalescing
the transfers in spite of the bounce buffers, or simply because of buffer
corruption.  (The BT driver seems to occasionally get hit by from this too,
except that it does not trap the transfer, and the system panics later
with vm_bounce_page_free.)  This "event" usually happens to me during a
savecore (on the rare occasion that a kernel coredump is actually taken
after a crash - the lack of kernel core dumps is another problem...).

and it's a little slower on a P5. Also moved the count mask and 'std'

02f90f3b3c Increased the double fault stack size from 512 to PAGE_SIZE. This is

About 300 bytes of variables were clobbered when I examined double
faults using ddb.  Perhaps a page that is known not to be accessed by
the double fault handler could be used.  Such pages are not easy to
find, since the double fault handler calls panic() which calls sync()
and possibly dumpsys().

bfd6eab381 Fixed bugs introduced in rev. 1.127 (some broken 16650 support was
unintentionally committed):
- the fifo was completely disabled for low speeds.  Apart from being
  unnecessarily inefficient, this invalidated com->tx_fifo_size.
- `ftl' became a bogus name.
- the 16650 probe breaks the COM_NOFIFO() case and has other bugs
  (disabled, not fixed).

Fixed bogus change of the fifo settings for the non-speed of 0.  This
bug made the above fifo bug occur even at non-low speeds.

Fixed the modes of the cua devices.  It isn't possible to set the uid
and gid correctly since the kernel can't know who uucp.dialer is.

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.

2838c9682a Implemented a (sorely needed for years) double fault handler to catch stack
overflows.
It sure would be nice if there was an unmapped page between the PCB and
the stack (and that the size of the stack was configurable!). With the
way things are now, the PCB will get clobbered before the double fault
handler gets control, making somewhat of a mess of things. Despite this,
it is still fairly easy to poke around in the overflowed stack to figure
out the cause.

There are still problems..  ld.so claims the libraries are the wrong

about needing ld.so.cache, and running a linux ldconfig is quite
educational.  You soon learn to run "chroot /compat/linux /bin/ldconfig"

all buses.

Known problems:
-The PCI probe code has not been tested. Someone with a PCI Bt card will
 have to validate it, but even if it is broken all cards the earlier version
 of this driver found in ISA compatibility mode should still be found.
-Still missing the BT956 PCI ID, so it will be found as an ISA card until
 someone suplies it.
-PCI interrupts go through an interrupt stub that returns an int until
 we remove the edge-triggered PCI compatibiliity cruft.
-ISA interrupts go through an interrupt stub until they pass in (void *).
-The driver could support more mboxes and concurrent commands by allocating
 structures separately and hanging them off the bt_data struct to get around
 the 4K page limit. Someone with documentation should do this and also
 enable tagged queuing.

87f6c6625d Pass 3 of the great devsw changes
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)
seems to work here..
complaints to the usual places.. :)

cde694287a Implement detection of whether or not bounce-buffering is required
for the particular card in use.  At the moment, I've set it to any of
the bt445S VLB cards (not the bt445C which apparently work) and the
bt5xx series (isa cards).  The 742 and PCI cards should not need it. :-)

It may be useful to have something like this:
#ifndef BOUNCE_BUFFERS
  if (bounce_buffers_required && more_than_16MB_ram)
    panic("this card requires bounce buffers for more than 16MB ram!")

array of softc pointers (which is usually static in size) to point to
the driver softc.

Changed some of the argument passing to some functions to make a little
more sense.

- Don't print out meaningless iCOMP numbers, those are for droids.

	- Use a fixed-point representation with 8 bits of fraction to store
	  the rate and rationalize the variable name.  It would be
	  possible to use even more fraction if it turns out to be
	  worthwhile (I rather doubt it).

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.

53ac6efbd8 OK, that's it..
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)

376c314995 the second set of changes in a move towards getting devices to be
totally dynamic. (the first was about 7 weeeks ago)

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,
each of the files has the following code inserted into it:

018309ece7 After having put on my Asbestos suit, complete the MFS_ROOT part of Terry's
mountroot changes.  This means that the mfs_initminiroot functionality
into the root mfs_mount....

070fc2ce12 Mainly cosmetic cleanups... It now uses more consistant message reporting
on the console, and no longer uses "SLXOS" which I suspect may be a
trademark... (I'm not sure, but this is not really a SLXOS driver anyway)

84478e7f42 Fixed setting of speed B0 - don't output a bogus divisor of 0 and a
random prescaler, just hang up.  This may fix hangup problems with
mgetty.

dc4a0cee58 Update the wd.c driver to use the new TAILQ scheme for device
buffer queue.  Also, create a new subroutine 'tqdisksort' that
is an improved version of the original disksort that also uses
TAILQs.

6ad175be4d Restored static variable `nsio_tty' which is used only by pstat(8). Made
it `const' to inhibit compiler warnings.

Added #include of <pccard/driver.h> to get prototypes.  <pccard/slot.h>
is still necessary for its side effect of exporting non-slot things.
