FAILESAFE is defined, NO_LOCK bit of CCR1 is cleared.
- CPU_WT_ALLOC enables write-through allocation.
of multiple PCI IDE controllers(Dyson), and some updates and cleanups from
John Hood, who originally made our IDE DMA stuff work :-).
I have run tests with 7 IDE drives connected to my system, all in DMA
mode, with no errors. Modulo any bugs, this stuff makes IDE look
really good (within it's limitations.)

internal modems. Currently detects a USR modem, and a couple Supra
modems... vendor id's for sio capabile cards welcomed...
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
option, since people started to trust the bogus claim. Once we're going
to handle 2.88 MB controllers, we have to redo the chip detection, by
now just leave it hidden.
files.i386.
We aren't sure if this new code and the old sound code will co-exist in a
kernel, so the device pcm0 line is left commented out in LINT.

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.

* lots of fixes to error handling-- mostly works now
* improve DMA timing config for Triton chipsets-- PIIX4 and UDMA drive
still untested
* generally improve DMA config in many ways-- mostly cleanup
* clean up boot-time messages
* rewrite PRD generation algorithm
* first wd timeout is now longer, to handle drive spinup

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
reported by Bruce Evans.
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.
that I snuck in to our GDB last year. This allows you to debug headless
machines by sharing the console port between the debugger and the system
console. It's not 100% reliabile, but it works well. It's optional
and disabled by default.

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!
