96b3554e5c Use COMPAT_PCI_DRIVER() for registration if it exists. This shouldn't
hurt the driver portability to 3.x too much for where drivers are shared.

424af31b45 Changed the type of id_port from short into int to avoid wrong
conversion from short to unsigned long which is an argument of
bus_alloc_resource.  Since the value -1 is used to indicate no port
reousece, id_port need to be signed (suggested by Doug Rabson and
Peter Wemm.)

54a8c69347 Stage 1 of a cleanup of the i386 interrupt registration mechanism.
Interrupts under the new scheme are managed by the i386 nexus with the
awareness of the resource manager.  There is further room for optimizing
the interfaces still.  All the users of register_intr()/intr_create()
should be gone, with the exception of pcic and i386/isa/clock.c.

7ceeede80c Always reset the isa hints after releasing the resources after probe,
because the act of doing the release kills the hints(!).  A quirk of
the wrapper caused it to reset all the settings, except perhaps for the
memory address. I've tested this with a real SMC 8013EPC - which uses
shared memory addresses - it seems to work OK.

3c0d8bc982 Always create attach points for the various child busses that can be
attached to the nexus.  With one exception, this (for example) allows
you to do wierd things like kldload the eisa bus on the fly and then
drivers, and have it auto probe the eisa bus when the drivers come online.

The one exception being pci, it only adds the pcib after the presence of
the pci bus is detected and that's #if'ed code.

A side effect of this is that isa and eisa will be attached to the nexus
directly rather than the PCI->ISA or PCI->EISA bridges.  I'm not sure if
this is good or bad at this point, but it seems to be closer to the way
things are for the i386 family...  This is likely to be followed up.

This also fixes compilation without a PCI bus configured and will allow
eisa to work without PCI too.

0f6bc47029 Make the bt isa driver work..
- fix cut/paste problem. :-)
- don't forget to call isa_dmacascade()
- reset the port after we release resources.

That last one is a trap to watch out for..  The isa bus driver uses the
same port/irq/mem/etc variables for the initial probe hints as it does
for allocation/deallocation tracking.  Releasing a resource clears the
variable and then you loose the hint during attach.. (ouch!)

a49a3d4433 Implement an EISA new-bus framework. The old driver probe mechanism
had a quirk that made a shim rather hard to implement properly and it was
just easier to convert the drivers in one go.  The changes to the
buslogic driver go beyond just this - the whole driver was new-bus'ed
including pci and isa.  I have only tested the EISA part of this so far.

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.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

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.

173c0b9aba Search bdevsw[] instead of the half-baked builtin table of devices
in the RB_ASKNAME case.  I had thought that I made this change in
rev.1.18, but rev.1.18 only affects obscure subcases of the
RB_DFLTROOT case (subcases where the compiled in default root is
not found in bdevsw[] -- then the root device is set to the first
device in the half-baked table that is also in bdevsw[]).

Removed yet more vestiges of config-time swap configuration.

Incidently, at line 1462 there is a return that prevents the generic

to know if we can take out the return and let the generic code "see" it.
I've left the return in because that's the way it worked before.

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.

2005b07aa8 1. Modify config to issue different code for debugging.
2.  Config complains if you use -g:

    Debugging is enabled by default, there is no ned to specify the -g option

3.  Config warns you if you don't use -s:

    Building kernel with full debugging symbols.  Do
    "config -s BSD" for historic partial symbolic support.
    To install the debugging kernel, do make install.debug

    (BSD was the name of the config file I used; I print out the same
    name).

4.  Modify Makefile.i386, Makefile.alpha, Makefile.pc98 and config to
    work if a kernel name other than 'kernel' is specified.  This is
    not absolutely necessary, but useful, and it was relatively easy.
    I now have a kernel called /crapshit :-)

5.  Modify Makefile.i386, Makefile.alpha, Makefile.pc98 "clean" target

6.  Modify all to install the stripped kernel by default and the debug

d02c233129 Add driver support for gigabit ethernet adapters based on the Alteon
Networks Tigon 1 and Tigon 2 chipsets. There are a _lot_ of OEM'ed
gigabit ethernet adapters out there which use the Alteon chipset so
this driver covers a fair amount of hardware. I know that it works with
the Alteon AceNIC, 3Com 3c985 and Netgear GA620, however it should also
work with the DEC/Compaq EtherWORKS 1000, Silicon Graphics Gigabit
ethernet board, NEC Gigabit Ethernet board and maybe even the IBM and
and Sun boards. The Netgear board is the cheapest (~$350US) but still
yields fairly good performance.

Support is provided for jumbo frames with all adapters (just set the
MTU to something larger than 1500 bytes), as well as hardware multicast
filtering and vlan tagging (in conjunction with the vlan support in
-current, which I should merge into -stable soon). There are some hooks
for checksum offload support, but they're turned off for now since
FreeBSD doesn't have an officially sanctioned way to support checksum
offloading (yet).

I have not added the 'device ti0' entry to GENERIC since the driver
with all the firmware compiled in is quite large, and it doesn't really
fit into the category of generic hardware.

47b9dbd431 Two changes to pmap_remove_all:
1. Switch to pmap_TLB_invalidate from invltlb, eliminating a full TLB
flush where a single-page flush suffices.  (Also, this eliminates some
unnecessary IPIs.)

2. Use "loadandclear" to update the pte, eliminating a race condition
on SMPs.

Change #2 should be committed to -STABLE.

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!

3aacd339f0 Fixed a couple of missing drive selects in wdreset(). This mainly
affects cases where there is a slave but no master.  These bugs
were usually recovered from provided ATAPI was configured, but only
after lengthy delays.  Configuring ATAPI still fixes some bugs for
non-atapi drives.

Don't wait for seek complete in wdreset().  If necessary for pre-ata
drives, it can be waited for later (we got it wrong by only looking
at it for drive 0 anyway).  It is set as part of a historical
signature for ata drives but doesn't say anything useful about the
reset state.  It is cleared as part of a non-historical signature
for atapi drives so that drivers which don't understand atapi drives
seem to see no drive.  Waiting for it caused lengthy delays and
broke the status returned by wdreset() in cases where the master
was not an ata drive.  Then the whole wdprobe() failed in some
cases where the recovery code didn't work.

Don't wait for drive ready in wdreset().  The considerations are
the same as for seek complete, except drive ready does say something
useful about the reset state of ata drives, and waiting for it
later is required anyway for such drives.

Lengthy delays can now be avoided by not configuring nonexistent
(ata) drives.  Unfortunately, this breaks detection of atapi drives
in some configurations.
