9baa6352dc Make some small tweaks to the messages to clean up some stuff
from last time. Some people have pointed out that there were some odd
side-effects in the changes I made. Two things are different:

- sc_print_addr() will print 'foodev0:' (i.e. sd0:, st0:, cd0:, etc...)
  if the device name is known. If it's not known, it'll use a longer
  notation. This shortens error messages back to a sane length.

- Added a small function called sc_print_init() to set the sc_printing
  flag so that sc_print_addr() will know that we want it to print a
  linefeed. Used this in scsi_device_attach() to restore proper carriage
  return printing behavior which I broke.

Remaining bogons: the NCR SCSI driver prints out information while the
device-specific attach routine is running with its own linefeeds. This
breaks up the individual messages emitted by the subdriver modules and
causes at least one message to appear on a line by itself without a
device spec prefix. I'm not sure of the correct way to fix this, and
I don't have any NCR SCSI hardware to test with anyway.

There's probably more, but I gather that a rewrite of the SCSI subsystem
is pending anyway, so I'll leave the rest to Those Who Know More About
This Than I (tm).

ab865e3435 After so many people have been bugging me :), finally implement
read-mode access to CD-ROM media in the worm(4) driver.  No whistles
and bells yet, like all the CDIO* commands, but at least a start.

In order to do this, i had to slightly rearrange the semantics of an
open(2) on the worm driver: now, opening it with O_NONBLOCK set means
no actual IO operations will be intended but only ioctls are to be
processed.  This mode is used by wormcontrol(8) to prepare a track
and/or session.

I have only been able to test this on a 2.2-GAMMA system by now, and
only the !DEVFS part is tested yet.  Also, i have only done a dummy
burn so far, but wouldn't expect many surprises else.  Report bugs to
me ASAP, if there's reasonable demand and i hear no objections, i
might consider merging it into the 2.2 branch as well.

c1b822b746 Do not accidentally default a device that failed probing to T_DIRECT
(since T_DIRECT just incidentally happens to be equal 0).  This causes
more harm than it would do good.  Instead , get it at the uk driver.

0f49e57b57 Removed `Debugger("no slices")'. It's normal and harmless to have no
slices in sd_open() after a media change when the previous sd_open()
discards the previous slices and then fails.  sd_open() just handles
media changes poorly and fails too often.

fc7c79b907 Make the SCSI probe messages more BSDish. This may raise a few eyebrows
("Hey! Who made _you_ the keeper of all things BSDish?!") but this has
bugged me for a long time, and now that I finally have the chance
to hack on it (and test the results), I'll take my chances. I can also
point to other BSD implementations for precedents if you put my back to
the wall.

The only thing that's changed is how the messages are formatted. Now,
instead of having this:

aha0 at 0x330-0x333 irq 11 drq 5 on isa
(aha0:3:0): "HP C1553A 9503" type 1 removable SCSI 2
st0(aha0:3:0): Sequential-Access density code 0x24, variable blocks, write-enabled
(aha0:3:1): "HP C1553A 9503" type 8 removable SCSI 2
ch0(aha0:3:1): Medium-Changer 6 slot(s) 1 drive(s) 0 arm(s) 0 i/e-slot(s)

We have this:

aha0 at 0x330-0x333 irq 11 drq 5 on isa
scbus0 at aha0 bus 0
st0 at scbus0 target 3 lun 0
st0: <HP C1553A 9503> type 1 removable SCSI 2
st0: Sequential-Access density code 0x24, variable blocks, write-enabled
ch0 at scbus0 target 3 lun 1
ch0: <HP C1553A 9503> type 8 removable SCSI 2
ch0: Medium-Changer 6 slot(s) 1 drive(s) 0 arm(s) 0 i/e-slot(s)

Which is (to me anyway) is a lot more pleasant to look at. (Call me
crazy -- g'head: you know you wanna -- but the previous messages remind
me of Linux. Ever see the output from the linux device probes? It's a mess
of copyright notices, version numbers/dates, author e-mail addresses and
other crap. Let's not go there, okay? Bleh.)

Notice that devices are now specified in terms of the scsi bus they
live on rather than the adapter. This better reflects the contents
of the kernel config file (if you use wired-down device specifications
anyway) and removes some ambiguity that may arise if you have a multi-
channel adapter with more than one bus.

Also, sc_print_addr() now generates messages like this:
st0 at scbus0 target 3 lun 0: NOT READY asc:3a,0 Medium not present

instead of this:
st0(aha0:3:0): NOT READY asc:3a,0 Medium not present

I also added a quirk entry for the HP Superstore 12000e 6 tape DAT
autoloader, which needs SC_MORE_LUS in order for the changer device
to be properly probed and attached. (I'm working on a chcontrol utility
to manipulate the changer on this drive which should hopefully be general
enough to work with other changers too. If you want the prototype I have
now, it's at ftp://skynet.ctr.columbia.edu/pub/freebsd/changer.c.)

Remaining bugs:

- The 'foodev0: yadda yadda yadda' bits should probably be printed entirely
  by the device-specific subdriver attach code instead of half by the
  scsi_device_attach() routine and half by the device specific attach
  routine like it is now.

- The wired-down device specifications in the kernel config file should
  be used to control bus/device probing to some extent rather than just
  for choosing names for devices we find. If the config says there's a
  device at scbus0 target 0 lun 0 called sd0, we should look there and
  check for a device that can be managed by the sd driver. If we don't
  find one, we should probably complain that there's no device there or
  that there is a device but of the wrong type. Once all the devices from
  the wired down list have been probed, the code can then autodetect and
  autoattach any devices that remain unassigned.

- Apparently some tape changers (hi Ulf!) return 'not ready/medium not
  present' when the magazine is loaded but a tape has not been put in the
  drive yet. This causes an open(/dev/ch0) to fail and prevents you from
  using the changer.c utility to load the first tape into the drive. My
  HP changer does not behave this way. The workaround is to manually load
  a tape into the drive before attempting to use the changer program, but
  you can get in trouble if you accidentally eject a tape without loading
  a new one and you're at a remote location: you won't be able to load
  any tapes anymore. I'm not sure what the correct software solution is
  for this but ideally there should be one.

- I should not be doing this: I'm the NIS guru, not the SCSI guru.
  (This is not my beautiful code. How did I get here? My god: what
  have I done?)

7b0951f009 Slightly re-order the sequence of commands issued, so try to send
the START UNIT command before testing whether the device is ready.
Maybe it should be done even earlier, i'm not 100 % sure.

Again, CD changers will most likely benefit from it.

While i was at it, also made the debugging case a little more verbose
about why the cdopen() yielded an ENXIO.  (Only in effect when
SCSIDEBUG is specified.)

Should eventually also go into 2.2.

802e82cdd2 Do something Peter Dufault long since intended to do: make a current
error code with ASC/ASCQ 4/1 (``Logical unit is in the process of
becoming ready'') non-fatal.  Retry the operation until it will
eventually either yield a real error condition, or finally succeed.

Devices like CD changers or tape drives with a freshly inserted
cartridge should benefit from this.

Should go into 2.2 after some testing in -current.  I'd like to see
this in the release if possible.

7cb29d3394 This update adds the support for != 512 byte sector SCSI devices to
the sd & od drivers. There is also slight changes to fdisk & newfs
in order to comply with different sectorsizes.
Currently sectors of size 512, 1024 & 2048 are supported, the only
restriction beeing in fdisk, which hunts for the sectorsize of
the device.
This is based on patches to od.c and the other system files by
John Gumb & Barry Scott, minor changes and the sd.c patches by
me.
There also exist some patches for the msdos filesys code, but I
havn't been able to test those (yet).
