f71c01cc52 Borrow phk's axe and apply the next stage of config(8)'s evolution.
Use Warner Losh's "hint" driver to decode ascii strings to fill the
resource table at boot time.

config(8) no longer generates an ioconf.c table - ie: the configuration
no longer has to be compiled into the kernel.  You can reconfigure your
isa devices with the likes of this at loader(8) time:
  set hint.ed.0.port=0x320

userconfig will be rewritten to use this style interface one day and will
move to /boot/userconfig.4th or something like that.

It is still possible to statically compile in a set of hints into a kernel
if you do not wish to use loader(8).  See the "hints" directive in GENERIC
as an example.

All device wiring has been moved out of config(8).  There is a set of
helper scripts (see i386/conf/gethints.pl, and the same for alpha and pc98)
that extract the 'at isa? port foo irq bar' from the old files and produces
a hints file.  If you install this file as /boot/device.hints (and update
/boot/defaults/loader.conf - You can do a build/install in sys/boot) then
loader will load it automatically for you.  You can also compile in the
hints directly with:  hints "device.hints"  as well.

There are a few things that I'm not too happy with yet.  Under this scheme,
things like LINT would no longer be useful as "documentation" of settings.
I have renamed this file to 'NOTES' and stored the example hints strings
in it.  However... this is not something that config(8) understands, so
there is a script that extracts the build-specific data from the
documentation file (NOTES) to produce a LINT that can be config'ed and
built.  A stack of man4 pages will need updating. :-/

Also, since there is no longer a difference between 'device' and
'pseudo-device' I collapsed the two together, and the resulting 'device'
takes a 'number of units' for devices that still have it statically
allocated.  eg:  'device fe 4' will compile the fe driver with NFE set
to 4.  You can then set hints for 4 units (0 - 3).  Also note that
'device fe0' will be interpreted as "zero units of 'fe'" which would be
bad, so there is a config warning for this.  This is only needed for
old drivers that still have static limits on numbers of units.
All the statically limited drivers that I could find were marked.

Please exercise EXTREME CAUTION when transitioning!

Note:
- the old driver still lives in src/sys/i386/isa, so that you can
  revert to it if something goes wrong.
- The module does not detach very well. Attaching works fine.

3f664fc689 A checkpoint of a part of a work-in-progress. Some more cleanups for
config(8).  This commit allows control of the creation of the
#include "foo.h" files.  We now only create them explicitly when needed.
BTW; these are mostly bad because they usually imply static limits on
numbers of units for devices.  eg: struct mysoftc sc[NFOO];
These static limits have Got To Go.

80060e8897 Connect the ISA and PCI compatability shims to an option. In this case
it's options COMPAT_OLDISA and COMPAT_OLDPCI.  This is meant to be a
fairly strong incentive to update the older drivers to newbus, but doesn't
(quite) leave anybody hanging with no hardware support.  I was talking with
a few folks and I was encouraged to simply break or disable the shims but
that was a bit too drastic for my liking.

4f9d49f140 Newbus-ify the USR Sportster TA Intern driver.
Enable the driver in sys/conf/files.i386.

In isa/isavar.h increase ISA_NPORT from 32 to 50. This is required
because this brain-damaged card maps 49 (!) port ranges. This does
not have a negative impact because this value only specifies the maximum
number of entries in a linked list and not the size of an array which
is allocated in all drivers.

The register/fifo access routines were not newbus-ified because
1) I knew that the old code worked and is simpler and more efficient
2) the if_ed driver does something similar and
3) the newbus macros collapse to inb/outb anyway.

2b944ee2b9 This is the 3rd stage of syscons code reorganization.
- Split terminal emulation code from the main part of the driver so
that we can have alternative terminal emulator modules if we like in
the future.  (We are not quite there yet, though.)

- Put sysmouse related code in a separate file, thus, simplifying the
main part of the driver.

As some files are added to the source tree, you need to run config(8)
before you compile a new kernel next time.

You shouldn't see any functional change by this commit; this is only
internal code reorganization.

68b683dc58 Compile *_genassym.c with ordinary ${CFLAGS}. The (small) needs for
-U_KERNEL became negative when all all the genassym.c's were converted
to be cross-built.  Related cleanups: PARAM went away, but was still
used here; KERNEL was renamed to _KERNEL, but was still KERNEL here;
the deprecated macros $@ and $< were still used here.

Use "genassym ... > ${.TARGET}", not "genassym -o $@ ...", so that
genassym(1) doesn't need to support -o.

Removed half-baked hard-coded dependencies of *_genassym.o on headers.
These objects should be added to the list of objects in the depend
rule to get full dependencies.  This doesn't happen automatically
because they are not linked into the kernel.  Half baked dependencies
don't really help.

5fe1db5b0a Remove the if_ze and if_zp drivers.
These drivers were cloned from the ed and ep drivers back in 1994
when PCMCIA cards were a very new thing and we had no other support
for such devices.  They treated the PCIC (the chip which controls the
PCCARD slot) as part of their device and generally hacked their way
to success.  They have significantly bit-rotted relative to their
ancestor drivers (ed & ep) and they were a dead-end on the evolution
path to proper PCCARD support in FreeBSD.

They have been terminally broken since August 18 where mdodd forgot
them and nobody seems to have missed them enough to fix them since.

I found no outstanding PRs against these drivers.

dda0e6f54e Update the WaveLAN/IEEE driver:
- Convert to new bus attachment scheme. Thanks to Blaz Zupan for doing
  the initial work here. One thing I changed was to have the attach
  and detach routines work like the PCI drivers, which means that in
  theory you should be able to load and unload the driver like the PCI
  NIC drivers, however the pccard support for this hasn't settled down
  yet so it doesn't quite work. Once the pccard work is done, I'll have
  to revisit this.

- Add device wi0 to PCCARD. If we're lucky, people should be able to
  install via their WaveLAN cards now.

- Add support for signal strength caching. The wicontrol utility has
  also been updated to allow zeroing and displaying the signal strength
  cache.

- Add a /sys/modules/wi directory and fix a Makefile to builf if_wi.ko.
  Currently this module is only built for the i386 platform, though once
  the pccard stuff is done it should be able to work on the alpha too.
  (Theoretically you should be able to plug one of the WaveLAN/IEEE ISA
  cards into an alpha with an ISA slot, but we'll see how that turns out.

- Update LINT to use only device wi0. There is no true ISA version of
  the WaveLAN/IEEE so we'll never use an ISA attachment.

- Update files.i386 so that if_wi is dependent on card.

4f76d87b21 Massive rewrite of pccard to convert it to newbus.
o Gut the compatibility interface, you now must attach with newbus.
o Unit numbers from pccardd are now ignored.  This may change the units
  assigned to a card.  It now uses the first available unit.
o kill old skeleton code that is now obsolete.
o Use newbus attachment code.
o cleanup interfile dependencies some.
o kill list of devices per slot.  we use the device tree for what we need.
o Remove now obsolete code.
o The ep driver (and maybe ed) may need some config file tweaks to
  allow it to attach.  See config files that were committed for examples
  on how to do this.

Drivers to be commited shortly.

This is an interrum fix until the new pccard.  ed, ep and sio will be
supported by me with this release, although others are welcome to try
to support other devices before new pccard is working.

I plan on doing minimal further work on this code base.  Be careful
when upgrading, since this code is known to work on my laptop and
those of a couple others as well, but your milage may vary.

BUGS TO BE FIXED:

o system memory isn't allocated yet, it will be soon.
o No devices actually have a pccard newbus attach in the tree.

BUGS THAT MIGHT BE FIXED:

o card removal, including suspend, usually hangs the system.

The new code has been tested by a number of people and all the important
bits work.  I've not been able to test the EISA code but will do so once
my hardware arrives.  Since I've changed nothing in the EISA code I suspect
it will perform the same manner as before.

Future changes involve whacking the ISA and PCCARD front ends to use
newbus and to convert the driver to bus_space and make it use ifmedia.

This is the first working network driver that supports MCA bus devices btw.

c6dfea0ebd Add sysctl variables for the Linuxulator. These reside under `compat.linux' as
discussed on current.

The following variables are defined (for now):

    osname (defaults to "Linux")
        Allow users to change the name of the OS as returned by uname(2),
        specially added for all those Linux Netscape users and statistics
        maniacs :-) We now have what we all wanted!

    osrelease (defaults to "2.2.5")
        Allow users to change the version of the OS as returned by uname(2).
        Since -current supports glibc2.1 now, change the default to 2.2.5
        (was 2.0.36).

    oss_version (defaults to 198144 [0x030600])
        This one will be used by the OSS_GETVERSION ioctl (PR 12917) which I
        can commit now that we have the MIB. The default version number is the
        lowest version possible with the current 'encoding'.

A note about imprisoned processes (see jail(2)):
  These variables are copy-on-write (as suggested by phk). This means that
  imprisoned processes will use the system wide value unless it is written/set
  by the process. From that moment on, a copy local to the prison will be
  used.

A note about the implementation:
  I choose to add a single pointer to struct prison, because I didn't like the
  idea of changing struct prison every time I come up with a new variable. As
  a side effect, the extra storage is only needed when a variable is set from

This approach makes atomic operations from KLDs significantly
faster on UP systems (though somewhat slower on SMP systems).

- Many static variables are moved to the softc structure.

- Added a new key function, PREV.  When this key is pressed, the vty
  immediately before the current vty will become foreground.  Analogue
  to PREV, which is usually assigned to the PrntScrn key.

- Modified the kernel console input function sccngetc() so that it
  handles function keys properly.

- Reorganized the screen update routine.

- VT switching code is reorganized.  It now should be slightly more
  robust than before.

- Added the DEVICE_RESUME function so that syscons no longer hooks the
  APM resume event directly.

- New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING,
  SC_NO_HISTORY and SC_NO_SYSMOUSE.
  Various parts of syscons can be omitted so that the kernel size is
  reduced.

  SC_PIXEL_MODE

  syscons.

  SC_DISABLE_DDBKEY

31a08ab08e Add device driver support for the Lucent WaveLAN/IEEE 802.11 PCMCIA
adapter (and some workalikes). Also add man pages and a wicontrol
utility to manipulate some of the card parameters.

This driver was written using information gleaned from the Lucent HCF Light
library, though it does not use any of the HCF Light code itself, mainly
because it's contaminated by the GPL (but also because it's pretty gross).
The HCF Light lacks certain featurs from the full (but proprietary) HCF
library, including 802.11 frame encapsulation support, however it has
just enough register information about the Hermes chip to allow someone
with enough spare time and energy to implement a proper driver. (I would
have prefered getting my hands on the Hermes manual, but that's proprietary
too. For those who are wondering, the Linux driver uses the proprietary
HCF library, but it's provided in object code form only.)

Note that I do not have access to a WavePOINT access point, so I have
only been able to test ad-hoc mode. The wicontrol utility can turn on
BSS mode, but I don't know for certain that the NIC will associate with
an access point correctly. Testers are encouraged to send their results
to me so that I can find out if I screwed up or not.

6182fdbda8 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

e05da2e941 Made booting with -a work for all configurations. Previously it
only worked for configurations with "swap on generic".

usr.sbin/config/config.y:
- ignore all "swap [on] device ...' specifications except for
  warning about them.  They haven't done anything related to swap
  for almost 4 years, and were previously silently ignored,
  except for "swap on generic" which stopped swap${KERNEL}.c
  from being generated.  Code to support swapping is now deader
  than before.

usr.sbin/config/mkswapconf.c:
- don't generate a dummy setconf() function in swap${KERNEL}.c.

sys/i386/conf/files.i386:
- swapgeneric.c is now standard.  It should be merged into autoconf.c
  so that it doesn't conflict with swap${KERNEL}.c for kernels named
  "generic".

sys/i386/i386/autoconf.c:
- don't call setroot() for mfs roots.  Since setroot() doesn't do anything
  harmful, this was just a waste of time, except possibly for booting with
  -a it may have helped prevent an undesireable call to setconf() by
  finding a bogus rootdev.
- honor -a for ffs roots.  -a now overrides all other ways of specifying
  the root device.  Previously, -r had precedence over -a, and the -a
  handling was usually a no-op.
- don't honor -a for non-ffs roots, since it would currently just get in
  the way of a clean panic.

sys/i386/i386/swapgeneric.c:
- don't declare things that are now always declared in swap${KERNEL}.c.
  Don't decide things that are now decided in autoconf.c.  Code to
  support the "generic" case is now dead instead of useless.

3e3e4375c8 Shoot the LKM support in the old wd/wdc/atapi driver set in the head and

code is permanently attached to the wd driver and is always probed.

I will add an extra option bit in the flags to disable an atapi probe on
either the master or slave if needed, if people want this.

Remember, this driver is destined to die some time.  It's possible that
it will loose all atapi support down the track and only be used for
dumb non-ATA disks and all ata/atapi devices will be handled by the new
ata system.

ATAPI, ATAPI_STATIC and CMD640 are no longer options, all are implicit.

55bfaed1c0 Fourth update to the new ATA/ATAPI driver:
Well, better late than newer, but things has been hectic
around here, sorry for the long delay.

DMA support has been added to the ATA disk driver.
This only works on Intel PIIX3/4, Acer Aladdin and Promise controllers.
The promise support works without the BIOS on the board,
and timing modes are set to support up to UDMA speed. This
solves the problems with having more than one promise controller
in the same system.
There is support for "generic" DMA, that might work on other
controllers, but now you have been warned :)
More chipset specific code will come soon, I have to find testers
with the approbiate HW, more on that when I have it ready.

The system now uses its own major numbers, please run MAKEDEV
with the devices you need (ad?, acd?, afd?, ast?).
For now the disk driver will also attach to the old wd major
so one can at least boot without this step, but be warned, this
will eventually go away. The bootblocks will have to be changed
before one can boot directly from an "ad" device though.

Fixed problems:

    All known hang problems should be solved
	The probe code has been sligthly changed, this should solve
	the reports I have lying around (I hope).

    Hangs when accessing ata & atapi device on the same channel simultaniously.
	A real braino in ata_start caused this, fixed.

As usual USE AT YOUR OWN RISK!!, this is still pre alpha level code.
Especially the DMA support can hose your disk real bad if anything
goes wrong, agaiin you have been warned :)

But please tell me how it works for you!

Enjoy!

- Refined internal interface in keyboard drivers so that:
  1. the side effect of device probe is kept minimal,
  2. polling mode function is added,
  3. and new ioctl and configuration options are added (see below).

- Added new ioctl: KDSETREPEAT
  Set keyboard typematic rate.  There has existed an ioctl command,
  KDSETRAD, for the same purpose.  However, KDSETRAD is dependent on
  the AT keyboard.  KDSETREPEAT provides more generic interface.
  KDSETRAD will still be supported in the atkbd driver.

- Added new configuration options:
  ATKBD_DFLT_KEYMAP
  Specify a keymap to be used as the default, built-in keymap.
  (There has been undocumented options, DKKEYMAP, UKKEYMAP, GRKEYMAP,
  SWKEYMAP, RUKEYMAP, ESKEYMAP, and ISKEYMAP to set the default keymap.
  These options are now gone for good.  The new option is more general.)

  KBD_DISABLE_KEYMAP_LOADING
  Don't allow the user to change the keymap.

8b89ef0a2d Finally!!
The much roumored replacement for our current IDE/ATA/ATAPI is
materialising in the CVS repositories around the globe.

So what does this bring us:

A new reengineered ATA/ATAPI subsystem, that tries to overcome
most of the deficiencies with the current drivers.

It supports PCI as well as ISA devices without all the hackery
in ide_pci.c to make PCI devices look like ISA counterparts.

It doesn't have the excessive wait problem on probe, in fact you
shouldn't notice any delay when your devices are getting probed.

Probing and attaching of devices are postponed until interrupts
are enabled (well almost, not finished yet for disks), making
things alot cleaner.

Improved performance, although DMA support is still WIP and not
in this pre alpha release, worldstone is faster with the new
driver compared to the old even with DMA.

So what does it take away:

There is NO support for old MFM/RLL/ESDI disks.
There is NO support for bad144, if your disk is bad, ditch it, it has
already outgrown its internal spare sectors, and is dying.

For you to try this out, you will have to modify your kernel config
file to use the "ata" controller instead of all wdc? entries.

example:

# for a PCI only system (most modern machines)
controller 	ata0
device		atadisk0	# ATA disks
device		atapicd0	# ATAPI CDROM's
device		atapist0	# ATAPI tapes

#You should add the following on ISA systems:
controller	ata1	at isa? port "IO_WD1" bio irq 14
controller	ata2	at isa? port "IO_WD2" bio irq 15

You can leave it all in there, the system knows how to manage.

For now this driver reuses the device entries from the old system
(that will probably change later), but remember that disks are
now numbered in the sequence they are found (like the SCSI system)
not as absolute positions as the old system.

Although I have tested this on all the systems I can get my hands on,
there might very well be gremlins in there, so use AT YOU OWN RISK!!
This is still WIP, so there are lots of rough edges and unfinished
things in there, and what I have in my lab might look very different
from whats in CVS at any given time. So please have all eventual
changes go through me, or chances are they just dissapears...

I would very much like to hear from you, both good and bad news
are very welcome.

Enjoy!!

95e5e988e0 Make our v_usecount vnode reference count work identically to the
original BSD code.  The association between the vnode and the vm_object
no longer includes reference counts.  The major difference is that
vm_object's are no longer freed gratuitiously from the vnode, and so
once an object is created for the vnode, it will last as long as the
vnode does.

When a vnode object reference count is incremented, then the underlying
vnode reference count is incremented also.  The two "objects" are now
more intimately related, and so the interactions are now much less
complex.

When vnodes are now normally placed onto the free queue with an object still
attached.  The rundown of the object happens at vnode rundown time, and
happens with exactly the same filesystem semantics of the original VFS
code.  There is absolutely no need for vnode_pager_uncache and other
travesties like that anymore.

A side-effect of these changes is that SMP locking should be much simpler,
the I/O copyin/copyout optimizations work, NFS should be more ponderable,
and further work on layered filesystems should be less frustrating, because
of the totally coherent management of the vnode objects and vnodes.

Please be careful with your system while running this code, but I would
greatly appreciate feedback as soon a reasonably possible.

5eaf45f67b I've been using these tweaks to enable the sound driver to talk to the

XXX this uses some rather ugly PnP bootstrap code that is *NOT* compatable

Submitted by:cgull@smoke.marlboro.vt.us <John Hood>

Original readme:

*** WARNING ***

This code has so far been tested on exactly one motherboard with two
identical drives known for their good DMA support.

This code, in the right circumstances, could corrupt data subtly,
silently, and invisibly, in much the same way that older PCI IDE
controllers do.  It's ALPHA-quality code; there's one or two major
gaps in my understanding of PCI IDE still.  Don't use this code on any
system with data that you care about; it's only good for hack boxes.
Expect that any data may be silently and randomly corrupted at any
moment.  It's a disk driver.  It has bugs.  Disk drivers with bugs
munch data.  It's a fact of life.

I also *STRONGLY* recommend getting a copy of your chipset's manual
and the ATA-2 or ATA-3 spec and making sure that timing modes on your
disk drives and IDE controller are being setup correctly by the BIOS--
because the driver makes only the lamest of attempts to do this just
now.

*** END WARNING ***

that said, i happen to think the code is working pretty well...

WHAT IT DOES:

this code adds support to the wd driver for bus mastering PCI IDE
controllers that follow the SFF-8038 standard.  (all the bus mastering
PCI IDE controllers i've seen so far do follow this standard.)  it
should provide busmastering on nearly any current P5 or P6 chipset,
specifically including any Intel chipset using one of the PIIX south
bridges-- this includes the '430FX, '430VX, '430HX, '430TX, '440LX,
and (i think) the Orion '450GX chipsets.  specific support is also
included for the VIA Apollo VP-1 chipset, as it appears in the
relabeled "HXPro" incarnation seen on cheap US$70 taiwanese
motherboards (that's what's in my development machine).  it works out
of the box on controllers that do DMA mode2; if my understanding is
correct, it'll probably work on Ultra-DMA33 controllers as well.
it'll probably work on busmastering IDE controllers in PCI slots, too,
but this is an area i am less sure about.

it cuts CPU usage considerably and improves drive performance
slightly.  usable numbers are difficult to come by with existing
benchmark tools, but experimentation on my K5-P90 system, with VIA
VP-1 chipset and Quantum Fireball 1080 drives, shows that disk i/o on
raw partitions imposes perhaps 5% cpu load.  cpu load during
filesystem i/o drops a lot, from near 100% to anywhere between 30% and
70%.  (the improvement may not be as large on an Intel chipset; from
what i can tell, the VIA VP-1 may not be very efficient with PCI I/O.)
disk performance improves by 5% or 10% with these drives.

real, visible, end-user performance improvement on a single user
machine is about nil. :) a kernel compile was sped up by a whole three
seconds.  it *does* feel a bit better-behaved when the system is
swapping heavily, but a better disk driver is not the fix for *that*
problem.

THE CODE:

this code is a patch to wd.c and wd82371.c, and associated header
files.  it should be considered alpha code; more work needs to be
done.

wd.c has fairly clean patches to add calls to busmaster code, as
implemented in wd82371.c and potentially elsewhere (one could imagine,
say, a Mac having a different DMA controller).

wd82371.c has been considerably reworked: the wddma interface that it
presents has been changed (expect more changes), many bugs have been
fixed, a new internal interface has been added for supporting
different chipsets, and the PCI probe has been considerably extended.

the interface between wd82371.c and wd.c is still fairly clean, but
i'm not sure it's in the right place.  there's a mess of issues around
ATA/ATAPI that need to be sorted out, including ATAPI support, CD-ROM
support, tape support, LS-120/Zip support, SFF-8038i DMA, UltraDMA,
PCI IDE controllers, bus probes, buggy controllers, controller timing
setup, drive timing setup, world peace and kitchen sinks.  whatever
happens with all this and however it gets partitioned, it is fairly
clear that wd.c needs some significant rework-- probably a complete
rewrite.

timing setup on disk controllers is something i've entirely punted on.
on my development machine, it appears that the BIOS does at least some
of the necessary timing setup.  i chose to restrict operation to
drives that are already configured for Mode4 PIO and Mode2 multiword
DMA, since the timing is essentially the same and many if not most
chipsets use the same control registers for DMA and PIO timing.

does anybody *know* whether BIOSes are required to do timing setup for
DMA modes on drives under their care?

error recovery is probably weak.  early on in development, i was
getting drive errors induced by bugs in the driver; i used these to
flush out the worst of the bugs in the driver's error handling, but
problems may remain.  i haven't got a drive with bad sectors i can
watch the driver flail on.

complaints about how wd82371.c has been reindented will be ignored
until the FreeBSD project has a real style policy, there is a
mechanism for individual authors to match it (indent flags or an emacs
c-mode or whatever), and it is enforced.  if i'm going to use a source
style i don't like, it would help if i could figure out what it *is*
(style(9) is about half of a policy), and a way to reasonably
duplicate it.  i ended up wasting a while trying to figure out what
the right thing to do was before deciding reformatting the whole thing
was the worst possible thing to do, except for all the other
possibilities.

i have maintained wd.c's indentation; that was not too hard,
fortunately.

TO INSTALL:

my dev box is freebsd 2.2.2 release.  fortunately, wd.c is a living
fossil, and has diverged very little recently.  included in this
tarball is a patch file, 'otherdiffs', for all files except wd82371.c,
my edited wd82371.c, a patch file, 'wd82371.c-diff-exact', against the
2.2.2 dist of 82371.c, and another patch file,
'wd82371.c-diff-whitespace', generated with diff -b (ignore
whitespace).  most of you not using 2.2.2 will probably have to use
this last patchfile with 'patch --ignore-whitespace'.  apply from the
kernel source tree root. as far as i can tell, this should apply
cleanly on anything from -current back to 2.2.2 and probably back to
2.2.0.  you, the kernel hacker, can figure out what to do from here.
if you need more specific directions, you probably should not be
experimenting with this code yet.

to enable DMA support, set flag 0x2000 for that drive in your config
file or in userconfig, as you would the 32-bit-PIO flag.  the driver
will then turn on DMA support if your drive and controller pass its
tests.  it's a bit picky, probably.  on discovering DMA mode failures
or disk errors or transfers that the DMA controller can't deal with,
the driver will fall back to PIO, so it is wise to setup the flags as
if PIO were still important.

'controller wdc0 at isa? port "IO_WD1" bio irq 14 flags 0xa0ffa0ff
vector wdintr' should work with nearly any PCI IDE controller.

i would *strongly* suggest booting single-user at first, and thrashing
the drive a bit while it's still mounted read-only.  this should be
fairly safe, even if the driver goes completely out to lunch.  it
might save you a reinstall.

one way to tell whether the driver is really using DMA is to check the
interrupt count during disk i/o with vmstat; DMA mode will add an
extremely low number of interrupts, as compared to even multi-sector
PIO.

boot -v will give you a copious register dump of timing-related info
on Intel and VIAtech chipsets, as well as PIO/DMA mode information on
all hard drives.  refer to your ATA and chipset documentation to
interpret these.

WHAT I'D LIKE FROM YOU and THINGS TO TEST:

reports.  success reports, failure reports, any kind of reports. :)
send them to cgull+ide@smoke.marlboro.vt.us.

i'd also like to see the kernel messages from various BIOSes (boot -v;
dmesg), along with info on the motherboard and BIOS on that machine.

i'm especially interested in reports on how this code works on the
various Intel chipsets, and whether the register dump works
correctly.  i'm also interested in hearing about other chipsets.

i'm especially interested in hearing success/failure reports for PCI
IDE controllers on cards, such as CMD's or Promise's new busmastering
IDE controllers.

UltraDMA-33 reports.

interoperation with ATAPI peripherals-- FreeBSD doesn't work with my
old Hitachi IDE CDROM, so i can't tell if I've broken anything. :)

i'd especially like to hear how the drive copes in DMA operation on
drives with bad sectors.  i haven't been able to find any such yet.

success/failure reports on older IDE drives with early support for DMA
modes-- those introduced between 1.5 and 3 years ago, typically
ranging from perhaps 400MB to 1.6GB.

failure reports on operation with more than one drive would be
appreciated.  the driver was developed with two drives on one
controller, the worst-case situation, and has been tested with one
drive on each controller, but you never know...

any reports of messages from the driver during normal operation,
especially "reverting to PIO mode", or "dmaverify odd vaddr or length"
(the DMA controller is strongly halfword oriented, and i'm curious to
know if any FreeBSD usage actually needs misaligned transfers).

performance reports.  beware that bonnie's CPU usage reporting is
useless for IDE drives; the best test i've found has been to run a
program that runs a spin loop at an idle priority and reports how many
iterations it manages, and even that sometimes produces numbers i
don't believe.  performance reports of multi-drive operation are
especially interesting; my system cannot sustain full throughput on
two drives on separate controllers, but that may just be a lame
motherboard.

THINGS I'M STILL MISSING CLUE ON:

* who's responsible for configuring DMA timing modes on IDE drives?
the BIOS or the driver?

* is there a spec for dealing with Ultra-DMA extensions?

* are there any chipsets or with bugs relating to DMA transfer that
should be blacklisted?

* are there any ATA interfaces that use some other kind of DMA
controller in conjunction with standard ATA protocol?

FINAL NOTE:

after having looked at the ATA-3 spec, all i can say is, "it's ugly".
*especially* electrically.  the IDE bus is best modeled as an
unterminated transmission line, these days.

for maximum reliability, keep your IDE cables as short as possible and
as few as possible.  from what i can tell, most current chipsets have
both IDE ports wired into a single buss, to a greater or lesser
degree.  using two cables means you double the length of this bus.

SCSI may have its warts, but at least the basic analog design of the
bus is still somewhat reasonable.  IDE passed beyond the veil two
years ago.

Thanks goes to Ulrike Nitzsche <ulrike@ifw-dresden.de> for giving me
a chance to test this.  Only the PCI driver is tested though.

One final patch will follow in a separate commit.  This is so that
everything up to here can be dragged into 2.2, if we decide so.

2fa4e5a7fc Set a more explicit #include path for building aix7xxx_asm, otherwise it
uses /usr/include/sys/*, which may point to a different build tree.  I'm
not sure that this is necessary, but there was a question mark over what
/usr/include/sys points to when building the "user mode" binaries in the
kernel code, especially when building the smp tree.

I suspect that the "right" line here is to use ${INCLUDES}, but that
causes warnings about unused static inline functions in stdio.h and ctype.h

This driver is based on OpenBSD's driver. I modified it to run under FreeBSd
and made it actually work usefully.
Afterwards, nao@tom-yam.or.jp (HAMADA Naoki) added EISA support as well as
early support for 3C900 Etherlink XL PCI and 3C905 Fast Etherlink XL PCI.
He also split up the driver in a bus independant and bus dependant parts.

d6b9e17eb5 Improved non-statistical (GUPROF) profiling:
- use a more accurate and more efficient method of compensating for
  overheads.  The old method counted too much time against leaf
  functions.
- normally use the Pentium timestamp counter if available.
  On Pentiums, the times are now accurate to within a couple of cpu
  clock cycles per function call in the (unlikely) event that there
  are no cache misses in or caused by the profiling code.
- optionally use an arbitrary Pentium event counter if available.
- optionally regress to using the i8254 counter.
- scaled the i8254 counter by a factor of 128.  Now the i8254 counters
  overflow slightly faster than the TSC counters for a 150MHz Pentium :-)
  (after about 16 seconds).  This is to avoid fractional overheads.

files.i386:
permon.c temporarily has to be classified as a profiling-routine
because a couple of functions in it may be called from profiling code.

options.i386:
- I586_CTR_GUPROF is currently unused (oops).
- I586_PMC_GUPROF should be something like 0x70000 to enable (but not
  use unless prof_machdep.c is changed) support for Pentium event
  counters.  7 is a control mode and the counter number 0 is somewhere
  in the 0000 bits (see perfmon.h for the encoding).

profile.h:
- added declarations.
- cleaned up separation of user mode declarations.

prof_machdep.c:
Mostly clock-select changes.  The default clock can be changed by
editing kmem.  There should be a sysctl for this.

subr_prof.c:
- added copyright.
- calibrate overheads for the new method.
- documented new method.
- fixed races and and machine dependencies in start/stop code.

mcount.c:
Use the new overhead compensation method.

gmon.h:
- changed GPROF4 counter type from unsigned to int.  Oops, this should
  be machine-dependent and/or int32_t.
- reorganized overhead counters.

d805b866fa This driver supports the SDL Communications RISCom/N2 ISA cards that is
based on the HD64570 chip. Both the 1 and 2 port cards is supported.

Line speeds of up to 2Mbps is possible. At this speed about 95% 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 X.21 interface is tested. The others may need
tweaks to the clock selection code.

d66a506616 Mega-commit for Linux emulator update.. This has been stress tested under
netscape-2.0 for Linux running all the Java stuff.  The scrollbars are now
working, at least on my machine. (whew! :-)

I'm uncomfortable with the size of this commit, but it's too
inter-dependant to easily seperate out.

The main changes:

COMPAT_LINUX is *GONE*.  Most of the code has been moved out of the i386
machine dependent section into the linux emulator itself.  The int 0x80
syscall code was almost identical to the lcall 7,0 code and a minor tweak
allows them to both be used with the same C code.  All kernels can now
just modload the lkm and it'll DTRT without having to rebuild the kernel
first.  Like IBCS2, you can statically compile it in with "options LINUX".

A pile of new syscalls implemented, including getdents(), llseek(),
readv(), writev(), msync(), personality().  The Linux-ELF libraries want
to use some of these.

linux_select() now obeys Linux semantics, ie: returns the time remaining
of the timeout value rather than leaving it the original value.

Quite a few bugs removed, including incorrect arguments being used in
syscalls..  eg:  mixups between passing the sigset as an int, vs passing
it as a pointer and doing a copyin(), missing return values, unhandled
cases, SIOC* ioctls, etc.

The build for the code has changed.  i386/conf/files now knows how
to build linux_genassym and generate linux_assym.h on the fly.

Supporting changes elsewhere in the kernel:

The user-mode signal trampoline has moved from the U area to immediately
below the top of the stack (below PS_STRINGS).  This allows the different
binary emulations to have their own signal trampoline code (which gets rid
of the hardwired syscall 103 (sigreturn on BSD, syslog on Linux)) and so
that the emulator can provide the exact "struct sigcontext *" argument to
the program's signal handlers.

The sigstack's "ss_flags" now uses SS_DISABLE and SS_ONSTACK flags, which
have the same values as the re-used SA_DISABLE and SA_ONSTACK which are
intended for sigaction only.  This enables the support of a SA_RESETHAND
flag to sigaction to implement the gross SYSV and Linux SA_ONESHOT signal
semantics where the signal handler is reset when it's triggered.

makesyscalls.sh no longer appends the struct sysentvec on the end of the
generated init_sysent.c code.  It's a lot saner to have it in a seperate
file rather than trying to update the structure inside the awk script. :-)

At exec time, the dozen bytes or so of signal trampoline code are copied
to the top of the user's stack, rather than obtaining the trampoline code
the old way by getting a clone of the parent's user area.  This allows
Linux and native binaries to freely exec each other without getting
trampolines mixed up.

9d2baf5cdf Update the Connectix QuickCam driver to match my current work.
- split driver into FreeBSD specific and camera specific portions
  (qcamio.c can run in user mode, with a Linux "driver top" etc,
   and qcam.c should be trivial to port to NetBSD and BSDI.)
- support for 4bppand bidirectional transfers working better
- start of interleaved data-transfers byte-stream decodes (some of this
  stuff has been pulled out for the moment to make it easier to debug)

At this point, anyone who wants to port it to other platforms should feel
free to do so.  Please feed changes directly back to me so that I can produce
a unified distribution.

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.

08d5844ce1 This is the new submission of the matcd driver. In addition to the
new driver code, there are diffs to several other existing files
on the system and a man page.

This version of matcd implements the rest of the key ioctls related to
playing audio CDs and reading table of contents information from any
type of disc.

This update also corrects several problems detected since the original
version 1(10) was released.  These include:
1.	Jordons report on the kernel -c string problem.
2.	A problem with the driver being confused by other types of
	devices located at addresses it probes.
3.	An old CD TOC wouldn't always be cleared after a disc change.
4.	Cleaned up code so -Wall yields no warnings on 2.0 and later.
5.	A problem with drive getting out of sync with the driver when
	changing between CD-Data and CD-DA.

There have only been two reports from the field relating to problems
so either the first release isn't really being used or doesn't have
many problems.

12cfa43650 Added the "eg0" interface driver for the 3Com "3c505" or "etherlink/+"
card.  This is the braindamaged card with the 80186 CPU on it.  It is
slow, probably not very good after all, but hey, if you have one lying
around doing nothing anyway...

Added the "zp0" driver to GENERIC.

226d4c89da Make diskslice files standard and remove option DISKSLICE. ufs_disksubr.c
needed a diskslice function yesterday and all disk drivers will need it.
The diskslice initialization routine should be configurable (but isn't).

648c711bb4 This is the latest version of the APM stuff from HOSOKAWA, I have looked
briefly over it, and see some serious architectural issues in this stuff.

On the other hand, I doubt that we will have any solution to these issues
before 2.1, so we might as well leave this in.

Most of the stuff is bracketed by #ifdef's so it shouldn't matter too much
in the normal case.
