the ATA/ATAPI driver. This solves the concurrency problem with
the new GEOM code, and also cuts a good deal of the patch size

6f87be981b Major update of the ATA RAID code, part 3:
Add code to properly detach/attach disks that are part of a RAID.

Mark a disk that is attached on an ATA channel belonging to a
RAID as a spare disk that can be used for rebuilding failed RAID1's.

Add support for rebuilding failed RAID1's.

Several fixes to the detach/attach code.

For replacing a disk in a failed RAID1 do the following:

Find the controller channel# of the failed disk.

Exec 'atacontrol detach <channel#>' to free the disk from the system.

Replace the failed disk with a new one of at least the same size.
If your have your disks in drawers/enclosures this can be done with
the system still running.

Exec 'atacontrol attach <channel#>' to add the disk to the system and
mark it as a valid spare for rebuild.

Exec 'atacontrol rebuild <array#>'

The system will rebuild the array on the fly, the array can still
be used during this, although with slower performance.

Please let me know of any problems with this!

e1605c6270 Major update of the ATA RAID code, part 2:

that a reboot will make the BIOS pick up the changed config.

6ddce9039b Major update of the ATA RAID code, part 1:
Overhaul of the attach/detach code and structures, there were some nasty
bugs in the old implementation. This made it possible to collapse the
ATA/ATAPI device control structures into one generic structure.

A note here, the kernel is NOT ready for detach of active devices,
it fails all over in random places, but for inactive devices it works.
However for ATA RAID this works, since the RAID abstration layer
insulates the buggy^H^H^H^H^H^Hfragile device subsystem from the
physical disks.

Proberly detect the RAID's from the BIOS, and mark critical RAID1
arrays as such, but continue if there is enough of the mirror left
to do so.

Properly fail arrays on a live system. For RAID0 that means return EIO,
and for RAID1 it means continue on the still working part of the mirror
if possible, else return EIO.
If the state changes, log this to the console.

Allow for Promise & Highpoint controllers/arrays to coexist on the
same machine. It is not possible to distribute arrays over different
makes of controllers though.

If Promise SuperSwap enclosures are used, signal disk state on the
status LED on the front.

Misc fixes that I had lying around for various minor bugs.

This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

8ec48c6dbf - Remove asleep(), await(), and M_ASLEEP.
- Callers of asleep() and await() have been converted to calling tsleep().
  The only caller outside of M_ASLEEP was the ata driver, which called both
  asleep() and await() with spl-raised, so there was no need for the
  asleep() and await() pair.  M_ASLEEP was unused.

will figure out what disappeared and properly fail those, and attach

1931cf940a - Heavyweight interrupt threads on the alpha for device I/O interrupts.
- Make softinterrupts (SWI's) almost completely MI, and divorce them
  completely from the x86 hardware interrupt code.
  - The ihandlers array is now gone.  Instead, there is a MI shandlers array
    that just contains SWI handlers.
  - Most of the former machine/ipl.h files have moved to a new sys/ipl.h.
- Stub out all the spl*() functions on all architectures.

IBM's DPTA and DTLA series of drives (no other disk vendors are known
to support this) on non-Promise controllers (promise controllers lockup
when given the tagged queuing specific commands).

0384fff8c5 Major update to the way synchronization is done in the kernel. Highlights
include:

* Mutual exclusion is used instead of spl*().  See mutex(9).  (Note: The
  alpha port is still in transition and currently uses both.)

* Per-CPU idle processes.

* Interrupts are run in their own separate kernel threads and can be
  preempted (i386 only).

21c3015a24 * Completely rewrite the alpha busspace to hide the implementation from
the drivers.
* Remove legacy inx/outx support from chipset and replace with macros
  which call busspace.
* Rework pci config accesses to route through the pcib device instead of
  calling a MD function directly.

With these changes it is possible to cleanly support machines which have
more than one independantly numbered PCI busses. As a bonus, the new
busspace implementation should be measurably faster than the old one.

3427651043 Ten'th update to the new ATA/ATAPI driver:
It been awhile since the last major update, as a benefit there
are some cool things in this one (and new bugs probably :) )...

The ATA driver has grown "real" timeout support for all devices.
This means that it should be possible to get in contact with
(especially) lost ATAPI devices. It also means that the ATA
driver is now usable on notebooks as it will DTRT on resume.

An experimental hack at utilizing the Promise66's at UDMA66 is
in there, but I cant test it. If someone feels like sending
me one, give me a ping.

The ATAPI DMA enableling scheme has been changed, also better DMA
support for the Aladdin chipset has been implemented for ATAPI
devices. Note that the Aladdin apparently only can do DMA reads
on ATAPI devices, and the Promise cant do ATAPI DMA at all.
I have seen problems on some ATAPI devices that should be able
to run in DMA mode, so if you encounter problems with hanging
atapi devices during the probe, or during access, disable DMA
in atapi-all.c, and let me know. It might be nessesary to do this
via a "white list" for known good devices...

The ATAPI CDROM driver can now use eject/close without hanging and
the bug that caused reading beyond the end of a CD has been fixed.
Media change is also handled proberly. DVD drives are identified
and are usable as CDROM devices at least, I dont have the HW to
test this further, see above :).

The ATAPI tape driver has gotten some support for using the DSC
method for not blocking the IDE channel during read/write when
the device has full buffers. It knows about the OnStream DI-30
device, support is not completed yet, but it can function as a
primitive backup medium, without filemarks, and without bad media
handeling. This is because the OnStream device doesn't handle this
(like everybody else) in HW. It also now supports getting/setting
the record position on devices that supports it.

Some rather major cleanups and rearrangements as well (cvs -b diff
is your freind). I'm closing in on declaring this for beta code,
most of the infrastruture is in place by now.

As usual USE AT YOUR OWN RISK!!, this is still alpha level code.
This driver can hose your disk real bad if anything goes wrong, but
now you have been warned :)

But please tell me how it works for you!

Enjoy!

c4217f94eb Nine'th update to the new ATA/ATAPI driver:
The atapi subsystem has gotten better error handeling and timeouts,
it also tries a REQUEST SENSE command when devices returns errors,
to give a little more info as to what went wrong. It might be a
little verbose for now, but I'm interested in as much feedback on
errors as possible, especially timeouts, as I'm a bit in doubt if
I've chosen resonable default values everywhere.

The disk driver has been changed a bit to prepare for tagged queing,
which is next on my list.

The disk driver has grown a dump routine, I got one implementation
from Darrell Anderson <anderson@cs.duke.edu> which also did
partial dumps (usefull on big memory machines) I left out the
partial stuff for now, and changed the rest alot to fit into the new
ad_request framework.

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.

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!!
