c5b193bfba Retire LFS.
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.

This is Junichi's v1.0 driver.

NOTE: Major device numbers have been changed to avoid conflict with other

      This driver is still considered "beta" quality, although we have been
      playing with it.  Please submit bugs to junichi and myself.

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
(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

61ca849927 From the author:
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.

6a796ce0a1 teach sio how to attach to isa PnP cards. This is mainly for use with

document new option EXTRA_SIO that will increase sio's internal data

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

*** 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.

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.

61b005296f This commit affects ELF kernels only.
Remove "setdefs.h" and arrange to generate it automatically at
ELF kernel build time.

"gensetdefs.c" is a utility which scans a set of ELF object files
and outputs a line ``DEFINE_SET(name, length);'' for each linker
set that it finds.  When generating an ELF kernel, this is run just
before the final link to generate "setdefs.h".

Remove the init_sets() function from "setdef0.c", and its call from
"machdep.c".  Since "gensetdefs.c" calculates the length of each
set, it is no longer necessary in an ELF kernel to count the set
elements at kernel initialization time.  Also remove "set_of_sets"
which was used for this purpose.

Link "setdef0" and "setdef1" into the kernel only if building for
ELF.  Since init_sets() is no longer used, there is no need to link
them into an a.out kernel.

5a9714de76 This mega-commit brings the following:
. 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.

9081eec1fb Make the necessary changes so that an ELF kernel can be built. I
have successfully built, booted, and run a number of different ELF
kernel configurations, including GENERIC.  LINT also builds and
links cleanly, though I have not tried to boot it.

The impact on developers is virtually nil, except for two things.
All linker sets that might possibly be present in the kernel must be
listed in "sys/i386/i386/setdefs.h".  And all C symbols that are
also referenced from assembly language code must be listed in
"sys/i386/include/asnames.h".  It so happens that failure to do
these things will have no impact on the a.out kernel.  But it will
break the build of the ELF kernel.

The ELF bootloader works, but it is not ready to commit quite yet.

d98667394d make obj before building the aic7xxx assembler. This puts the object

3d4d8fe94d Sanitize APM a bit. Convert various #ifdef to id_flags instead.
You may want to add "flags 0x31" to apm0 if you have a lousy
