reverting to a single (short) INQUIRY command during probe. Compensate in siop
by trying PPR on all targets on SCSI-3 buses and falling back to WDTR/SDTR if
PPR rejected.
Problem found by mickey@. Tested on a wide variety of devices by Marco.

instances of bad LUNs and add SCSIFORCELUN_BUSES and
SCSIFORCELUN_TARGETS options.
ok miod@ deraadt@. Tested in the Marco Peereboom torture chamber.

UMASS_QUIRK_FORCE_SHORT_INQUIRY. Fixes a bunch of USB devices. Based
on work by Mycroft in NetBSD.
ok tdeval@ deraadt@.

moreluns field in scsi_link structure. Instead, treat an INQUIRY
result that duplicates the INQUIRY result of LUN 0 as proof the LUN
does not exist. Compensate for lack of SDEV_NOLUNS where necessary by
setting sc_link->luns to 1, which has the same effect. From Marco
Peereboom.
Don't issue Test Unit Ready command before INQUIRY command - not
necessary and potentially harmful to devices with ADEV_NOTUR quirk
since quirks have not been set yet. From mycroft@NetBSD
ok deraadt@, mvme* changes by miod@.

is trying to bring in.
1) Change name of SDEV_NOCDB6 to SDEV_ONLYBIG to align it with the
same quirk in NetBSD, and make it more clear what it is trying to do.
i.e. force the use of READ_BIG/WRITE_BIG commands, not suppress all
use of 6 byte CDB's.
2) Check SDEV_ONLYBIG in cd.c as well as sd.c. i.e. both places where
a choice is made to use the 6 or 10 byte versions of READ/WRITE.
3) Actually make use of the ADEV_NOTUR (No TEST UNIT READY) quirk to
suppress the emission of TEST UNIT READY commands.
4) Add some explanatory comments from NetBSD to scsiconf.h so that the
use of the quirks is made clear.

Use increased retries number and don't ignore SCSI_IGNORE_NOT_READY
when call scsi_test_unit_ready() for cd-rom, this makes system wait
if drive is loading media.
Tested by millert@ and fgsch@; some input and ok from krw@.
Problem reported by The lord of the CD-writers

do not support 6 byte CDBs.
This quirk is used for OLYMPUS USB cameras.
Loosely based on code in FreeBSD.

ugly INQUIRY snooping but avoids adding even uglier #ifdef's to turn
off stuff, e.g. tagged queuing.
Add two disk drives now known to lie about supporting tagged queuing
to quirks table. One from millert@ (<MICROP, 4421-07 0329SJ, 0329>)
and one from Hakan Olsson (<SEAGATE, ST150176LW, 0002>).
Add field 'inquiry_flags2' to struct scsi_link to hold flags2 field
from struct scsi_inquiry_data. These flags relate to SCSI-3 specific
features.
Clean up some logic, eliminating need for TARF_PPR flag.

watchdog per command. Reserve 4 bits of the flags field for the HBA's
private use (e.g., for saying whether the commands in the middle of
being watchdogged....).

BSD autoconf.
Don't use POLL & NOSLEEP mode if attaching after autoconf
|
|
in NetBSD). Look at Inquiry data during probing to further set quirks
based upon device capabilities. Thanks to Todd.Miller@courtesan.com for
doing the grunt work and encouraging this to get done fully.

Also, to support at least first level SCSI-3 hierarchical luns, fatten luns
to 16 bits too.

More SCSI logic from NetBSD-current
Some tape fixes. ATAPI tapes do not work yet for most operations.

default. Use "option SCSIVERBOSE=0" to turn off (only added 8Kb to my kernel).
From the NetBSD commit message:
Add in more detailed SCSI error printing, based off of final SCSI-2 spec.
This will also print out things like progress indicator errors, and will
also dump out additional sense bytes that haven't been decoded.

to:
* New changer driver.
* Better optical support.
* Different `done' semantics.
* New quirks for SCSI QIC tape driver, SCSI floppy drives.
* Better support for SCSI-I devices.
Everybody needs to test this.

to 8 internally so that drivers do not need to init it for regular scsi :-)

* Implemented NetBSD PR#2529, adding ZIP 100.
* Added MTIOCTOP support to acd, cd, and sd.
* Implemented eject on close for acd, cd, and sd.
`mt -f /dev/rcd0d offline' now ejects a mounted {acd|cd|sd} when it is
unmounted.

- scsi prototypes.
- Add SCSI scanner support by Kenneth Stailey and Joachim Koenig-Baltes,
hacked a but. Needs more work.
ss.c:
- Truncate to the window size in ssminphys(), not ssread().
- Missed some prototyping foo.
- Minor tweak; make sure window size is 0 on close.
- Change variable name to avoid GCC warning.
- Handle EOF a little differently.

"command aborted" status)
Handle cases like the following:
- controller calls scsi_done() with error XS_TIMEOUT
- scsi_done() calls sddone()
- sddone() calls disk_unbusy()
- scsi_done() calls controller to retry command (missing the
call to disk_busy())
- controller calls scsi_done()
- scsi_done() calls sddone()
- sddone() calls disk_busy(), which panics because of the imbalance.
Bug noticed by Leo Weppleman, who also suggested this fix; pass an additional
boolean argument ("complete") to the device's "done" routine, with a
value of `0' passed from the previous call to "done", and add an additional
call to "done" when the xfer resources are freed.
