fd4b4ecc73 Add the ability to use ATAPI devices via CAM.
The CAM<>ATAPI layer was submitted by "Thomas Quinot <thomas@cuivre.fr.eu.org>"
changes form the version on the net by me (formatting, ability to be used
alone without the ATAPI native device driver, proper speed reporting...)

See /sys/conf/NOTES for usage.

b3d86d9ca2 OK, dont rely on the upper layers handling iosize_max correctly,
instead rely on ATAPI devices ability to do the work instead.

091a610ac9 Fix the breakage of tagged queueing that the busdma integration
introduced. Since its now only possible to have one DMA control
block at a time, we move the setup to dmastart instead.

fe86c44885 Add new support for locking an ATA channel and use that throughout
the ATA/ATAPI driver. This solves the concurrency problem with
the new GEOM code, and also cuts a good deal of the patch size
in the upcoming MFC.

e1605c6270 Major update of the ATA RAID code, part 2:
More cleanups of the RAID1 failure mode code.

Add functionality that writes the changed RAID config setup
back to the disks (in controller BIOS specific format), so
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.

Dont flush the disk cache on BIO_ORDERED anymore.

Cleanup the tests for DMA on ATAPI devices.

Allow to share ALL irq's even the std irg 14 & 15.

Fix calculation bug in end of media code on CD's.

Add REZERO on opening a CDR/CDRW.

Cleanup ataioctl a bit.

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.

0978669829 "Fix" the previous initial attempt at fixing TUNABLE_INT(). This time
around, use a common function for looking up and extracting the tunables
from the kernel environment.  This saves duplicating the same function
over and over again.  This way typically has an overhead of 8 bytes + the
path string, versus about 26 bytes + the path string.

81930014ef Make the TUNABLE_*() macros look and behave more consistantly like the
SYSCTL_*() macros.  TUNABLE_INT_DECL() was an odd name because it didn't
actually declare the int, which is what the name suggests it would do.

7acf4af808 Use PLAY_MSF instead of PLAY_BIG when doing audio play.
The fixes the problem of PLAY_BIG not being implemented on
some modern drives.

The problem now is that some old drives use BSD encoding
in the MSF case, which they dont tell, and which is also
not according to spec *sigh*. Hopefully there are not
too many of those still alive, or I hereby grant
license to kill the firmware writers that wrote the mess.

see atacontrol(8) for more.

Also the ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC and ATA_ENABLE_TAGS
options are gone, use the tuneables listed in ata.4 instead from
the loader (this makes it possible to switch off DMA before the
driver has to touch the devices on broken hardware).

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.

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.
