midlayer that a scsi device has appeared or dissapeared. the midlayer will
queue an event and run it in the system workq (which has process context)
to handle the attach or detach.

errnos. Note that the error strings are being ignored, since we long ago
decided to not spam the console, and there is no other nice way to use the
errors (without changing the ioctls to pass it back)
The errno is now useful, since we can pass b_error from failing IO up, and
the drive can decide how to use that

so we can guarantee that any of the paths we push the io down later will
work.
with help from a discussion from beck and krw

is worth noting that the device on mpath will persist even if all the paths
behind it have gone away. returning the paths will allow operations to work
against the device again.
|
|
thinks they could be available via multiple paths. those stolen
devices are then made available via mpath(4).
this is the minimum amount of code to implement the stealing. it
is generally broken and very brittle, so it is currently disabled.
it is going in so i can work on it in the tree.

we need this to get some clue as to which ports are which on an fc fabric.

one by tedu@. It doesn't do anything smart yet, it just uses
plain old disksort. we also keep the old method of queueing bufs
since some miods have crazy MD drivers that need some love.

action if necessary.

a vpd page that uniquely identifies a device no matter what bus topology or
addressing was used to find it.
we have a workaround for old school scsi devices that do not differentiate
between luns. if the inq data for high luns is the same as the inq data
for lun 0, we assume it is one of these buggy devices.
the problem with this is that things like SANs present multiple
volumes as luns and they all have the same inq data. if you wanted
to present more than one volume to openbsd you would only ever see
the first one.
devices give us a mechanism to differentiate between luns, so now
i do get all my volumes attached in openbsde.

keeps it on the stack till we attach a driver to it. then it copies
the inquiry data int the scsi_link struct.
this diff uses the scsi_link struct instead of the stack for that data,
which makes the inq data for users of the scsi_link struct available much
earlier during device probe.

flagged SCSI_DATA_OUT) and data that has been returned (for commands
flagged SCSI_DATA_IN). This is better than just printing the data
buffer before the command is issued since that does not include any
data that has been read. e.g. INQUIRY data, as thib@ and I discovered.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

instead. We do not make use of the PMI and RELADDR bits in the
READ CAPACITY command, and thus there is no difference between
cd and sd capacity handling. Brings cd and sd more into line,
shrinks code and makes things easier to understand.
Make types for blocksize and disksize consistant and MI.
Make cdopen() as silent as sdopen().

scsi_read_cap_data as READ_CD_CAPACITY, scsi_read_cd_capacity and
scsi_read_cd_cap_data respectively. No functional change as all were
identical to their counterparts.
|
|
SENSE_NOT_READY_BECOMING_READY sense errors. Some devices such as USB
Zip250 drives return the former when they mean the latter. Give the
first TEST UNIT READY command three times the usual retries so more
devices have time to get ready. This allows more removable devices to
detect media details and avoid issuing 'drive offline' messages.

RAW_PART will always be 0 -> disksize, so the bounds check will always
pass for i/o's to valid addresses. Now the i/o will be properly truncated
if it goes past the end of the device. This prevents various adverse
impacts of issuing i/o's for data past the end of the device.
Repeatedly requested by todd@.

errors before issuing INQUIRY. Fixes Sony YE-Data floppy drive and
probably other devices at the cost of possibly breaking some 10 year
old CD-ROM drives. Un-special cases mvme68k which was forcing these
initial TURs.
Now wait for the inevitable weird USB device that breaks to surface.

debug output shows the xs/command before it's issued rather than
displaying it on command completion. Some commands don't come back
and it would be nice to see their details.
While here nuke invocations of scsi_show* in umass. If you want SCSI
debug output use SCSI debug options.
Only affects SCSI debug output.
