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.

7ebc82d6ec Make an ATAPI CD device appear as /dev/acdN and the individual
tracks as /dev/acdNtY.

This solves the problems with having to deal with howmany and which
devices are open.

For hysterical reasons ONLY, make a link to both the acdNa & acdNc devices.

8ea3ce2aac Refine the detach/attach code.
Proberly fail outstanding bio requests on devices that are detached.

This makes it possible to change between disk/cdrom/dvd/whathaveyou
in a notebook, just by suspending it, changing the device in the
bay (or what you model calls it), unsuspend and the ATA driver
will figure out what disappeared and properly fail those, and attach
any new devices found.

8563f77dc9 Add support for tagged queuing on ATA drives. There is only support for
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).
It gives especially master/slave comboes about 5% better performance.

Add support for the Promise ATA100 OEM chip (pdc20265)

Add support for the Cyrix 5530

Change the way status is read from the drives, use the alternate
status reg when possible.

Better support for DEVFS, the acdXtY devices are now created when needed.

Lots of little cleanups.

7caf73fb3c Add DVD-RAM support.
The driver constructs a fake disklabel that makes the 'a' partition
cover the entire DVD-RAM disk. This cannot be changed from the user
side. This solution was chosen because most DVD-RAM will have a
UDF (or until we have that CD9660) filesystem on it covering the
entire disk, its not really thought as a real random access device.

This might change over time, but for now this is what we have, and
it is compatible with CDROM's etc, that makes using the minidisk
subsystem less than ideal, because of !modulo BDEV_SIZE blocks.

47351d2774 Update the ata driver to take more advantage of newbus, this
was needed to make attach/detach of devices work, which is
needed for the PCCARD support.
(PCCARD support is still not working though, more to come on that)

Support the CMD646 chip which is used on many alphas, sadly only
in WDMA2 mode, as the silicon is broken beyond belief for UDMA modes.

Lots of cosmetic fixes here and there.

Sorry for the size of this megapatchfromhell but it was not
possible otherwise...

newbus patches based on work from: dfr (Doug Rabson)

fe08efdcfb General cleanup.
Dont be so verbose in the probe, only ONE line printed now, to get more
info boot verbose. Centralise most printf's in ata-all & ata-dma to use
the ata_printf function, it saves alot of codelines.

Repeat the identify command if drive fails the first.

Protect the timeout functions with splbio.

Dont update the transfer details before we are sure the transfer
succeded, this way they are proberly retried on errors.

Move the handling of next_writeable to userland.

Use the READ_CD command to read CD's. That enables us to read _anything_
via the normal read/write interface. This kindof obsoletes the READAUDIO
ioctl, but we keep that for now.

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!

9dcbe2404a Convert DEVFS hooks in (most) drivers to make_dev().
Diskslice/label code not yet handled.

Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)

Add the correct hook for devfs to kern_conf.c

The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.

A few drivers had minor additional cleanups performed relating to cdevsw
registration.

A few drivers don't register a cdevsw{} anymore, but only use make_dev().

b9bb98b32b Added driver to support ATAPI floppies ie LS-120 & ZIP drives.
Added "options ATA_STATIC_ID" that wires ATA disks like the old wd driver.

Fixed problems:

	Dont use more sectors/intr than the drive supports.
	Fix announce of > 8.4G disks.
	Dont call ad_interrupt/ad_transfer when no disks config'd.
	Use the right page# for CDR write mode params.
	Fix breakage when no PCI support in kernel.
	Implement DEVFS stuff.

General code clenaup.

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!!
