This code will be turned on with the TWO options
DEVFS and SLICE. (see LINT)
Two labels PRE_DEVFS_SLICE and POST_DEVFS_SLICE will deliniate these changes.
/dev will be automatically mounted by init (thanks phk)
on bootup. See /sys/dev/slice/slice.4 for more info.
All code should act the same without these options enabled.

This code does not support the following:
bad144 handling.
Persistance. (My head is still hurting from the last time we discussed this)
ATAPI flopies are not handled by the SLICE code yet.
When this code is running, all major numbers are arbitrary and COULD
be dynamically assigned. (this is not done, for POLA only)
Minor numbers for disk slices ARE arbitray and dynamically assigned.

_KPOSIX_PRIORITY_SCHEDULING options to work. Changes:
Change all "posix4" to "p1003_1b". Misnamed files are left
as "posix4" until I'm told if I can simply delete them and add
new ones;
Add _POSIX_PRIORITY_SCHEDULING system calls for FreeBSD and Linux;
Add man pages for _POSIX_PRIORITY_SCHEDULING system calls;
Add options to LINT;
Minor fixes to P1003_1B code during testing.
Uncommented css0. It compiles OK.
Moved trix0 so that it compiles OK when uncommented. Uncommented
it. Drivers with the same interrupt handler must be together in
config files so that config(8)'s simple avoidance of redundant
declarations of interrupt handlers works (config emits a declaration
unless it would duplicate the previous one).
Commented out NO_LKM. Negative options should not be configured
in LINT. There should be no negative options for subsystems.
LKMs should never have been standard or the default.
If you want to play with it, you can find the final version of the
code in the repository the tag LFS_RETIREMENT.
If somebody makes LFS work again, adding it back is certainly
desireable, but as it is now nobody seems to care much about it,
and it has suffered considerable bitrot since its somewhat haphazard
integration.
R.I.P
This introduce an xxxFS_BOOT for each of the rootable filesystems.
(Presently not required, but encouraged to allow a smooth move of option *FS
to opt_dontuse.h later.)
LFS is temporarily disabled, and will be re-enabled tomorrow.
This is Junichi's v1.0 driver.
NOTE: Major device numbers have been changed to avoid conflict with other
FreeBSD 3.0 devices. The new numbers should be considered "official."
This driver is still considered "beta" quality, although we have been
playing with it. Please submit bugs to junichi and myself.

(mutant) Crystal CSS4236 chip on the Intel PR440FX SMP motherboard.
XXX this uses some rather ugly PnP bootstrap code that is *NOT* compatable
with 'controller pnp0' or *ANY* other PnP devices. If you use some other
PnP devices, enabling css0 will burn your house down. :-] The
"simplified" PnP init sequence directly blats your config(8) settings onto
the chip. I'm pretty sure 'css0' will conflict with 'mss0', this whole
area desperately needs a cleanup.
I have been using the following with some success on the PR440FX:
controller snd0
device css0 at isa? port 0x534 irq 5 drq 1 flags 0x08 vector adintr
device opl0 at isa? port 0x388
device mpu0 at isa? port 0x330 irq 10 vector mpuintr
Here are the remanding changes required to support the Ensoniq
Soundscape using FreeBSD 3.0-current.
Notes:
1) ad1848_init already has code to detect if DMA_DUPLEX should
be set so it is not necessary (and is in fact a mistake) to
hard code setting it. Not all soundcards (i.e. the current
sscape driver) are capable of using DMA_DUPLEX.
2) The other changes are hopefully self explanatory. Feel free
to let me know if you need additional information.

* Rename/reorder all of the pccard structures, change many of the member

naming schemes.
* Rename a bunch of parameter and local variable names to be more

* Renamed the PCCARD 'crd' device to be the 'card' device
* KNF and make the code consistant where it was obvious.
* ifdef'd out some unused code

More cleanup to follow, but this part is safe for RELENG_2_2, too.

document new option EXTRA_SIO that will increase sio's internal data
structures to support X more serial ports... these are used by the
PnP part of sio for attaching... If you don't have it specified, it
will default to 2... This is defaulted to 0 if you don't have PnP
compiled into your kernel...
also document that if you set the PnP flags (pnp x flags y) to 0x1 that
the modem will be refused to be recognized by the sio driver... this
is for people that want the traditional isa driver to probe and attach
the modem... (for keeping legacy sio numbering)
Hide the bogus FDC ``chip type'' display behind a (mostly) undocumented

We aren't sure if this new code and the old sound code will co-exist in a

you don't want this (and the documentation explains why), but if you
use ipfw as an as-needed casual filter as needed which normally runs as
'allow all' then having the kernel and /sbin/ipfw get out of sync is a
*MAJOR* pain in the behind.

Moved description of sio 16650A flag to the sio section and rewrote the
description. It was in the generic console flags section.
Added undocumented options CPU_UPGRADE_HW_CACHE and WLDEBUG.
- Added the psm options PSM_HOOKAPM and PSM_RESETAFTERSUSPEND.
LINT:
- Added the psm options PSM_HOOKAPM and PSM_RESETAFTERSUSPEND.
- Added comments on the flag 0x20 for syscons.
- Clarified descriptions on the flags (0x02, 0x04) regarding the cursor
shape in syscons.
This eliminates a lot of #ifdef SMP type code. Things like _curproc reside
in a data page that is unique on each cpu, eliminating the expensive macros
like: #define curproc (SMPcurproc[cpunumber()])
There are some unresolved bootstrap and address space sharing issues at
present, but Steve is waiting on this for other work. There is still some
strictly temporary code present that isn't exactly pretty.
This is part of a larger change that has run into some bumps, this part is
standalone so it should be safe. The temporary code goes away when the
full idle cpu support is finished.

NETNATM --> NATM

Bruce also pointed out that NATM is confusing since config(8) defines
NATM as the number of atm pseudo device in "BUILD_DIR/atm.h".
We might change the name in the future but leave it as it is for now.

to fill in the nfs_diskless structure, at the cost of some kernel
bloat. The advantage is that this code works on a wider range of
network adapters than netboot. Several new kernel options are
documented in LINT.
Obtained from: parts of the code comes from NetBSD.
. It makes cd9660 root f/s working again.
. It makes CD9660 a new-style option.
. It adds support to mount an ISO9660 multi-session CD-ROM as the root
filesystem (the last session actually, but that's what is expected
behaviour).
Sigh. The CDIOREADTOCENTRYS did a copyout() of its own, and thus has
been unusable for me for this work. Too bad it didn't simply stuff
the max 100 entries into the struct ioc_read_toc_entry, but relied on
a user supplied data buffer instead. :-( I now had to reinvent the
wheel, and created a CDIOREADTOCENTRY ioctl command that can be used
in a kernel context.
While doing this, i noticed the following bogosities in existing CD-ROM
drivers:
wcd: This driver is likely to be totally bogus when someone tries
two succeeding CDIOREADTOCENTRYS (or now CDIOREADTOCENTRY)
commands with requesting MSF format, since it apparently
operates on an internal table.
scd: This driver apparently returns just a single TOC entry only for
the CDIOREADTOCENTRYS command.
I have only been able to test the CDIOREADTOCENTRY command with the
cd(4) driver. I hereby request the respective maintainers of the
other CD-ROM drivers to verify my code for their driver. When it
comes to merging this CD-ROM multisession stuff into RELENG_2_2 i will
only consider drivers where i've got a confirmation that it actually
works.
There are various options documented in i386/conf/LINT, there is more to
come over the next few days.
The kernel should run pretty much "as before" without the options to
activate SMP mode.
There are a handful of known "loose ends" that need to be fixed, but
have been put off since the SMP kernel is in a moderately good condition
at the moment.
This commit is the result of the tinkering and testing over the last 14
months by many people. A special thanks to Steve Passe for implementing
the APIC code!
Added obsolete option GATEWAY so that kern_opt.c gets tested.
Added undocumented options LOCKF_DEBUG and SIMPLELOCK_DEBUG so

that all of kern/kern_lockf.c shouldn't have been moved from ufs.
The debugging parts are very fs-dependent.

variable `kern.maxvnodes' which gives much better control over vnode
allocation than EXTRAVNODES (except in -current between 1995/10/28 and
1996/11/12, kern.maxvnodes was read-only and thus useless).
I have no idea if this works since I don't have one of the cards to test.
I also don't know what the LINT and GENERIC entries should look like,
so I just made up some values for now and left them commented out.
