Driver for DaynaPORT SCSI/Link (dse.4).

Written by Hiroshi Noguchi, of which an updated version was posted to
port-mac68k in 2001.

Attachments were added to kernel configs for platforms that already had
the Cabletron (se.4) driver added, although other platorms may benefit.

Reviewed on tech-net by Izumi Tsutsui.

Split some common stuff into scsi_subr module.  This enables loading
of the iscsi module whether or not there are any scsi things built
into the kernel.

Addresses the iscsi portion of kern/56772

Fix PR kern/53949:
Fix inconsistent/incomplete file mark handling to conform again
to mtio(4) at close(2) time. This was necessary as the PREVENT/ALLOW
bracket was reduced from a whole mount session to cover only the
open(2)/close(2) time on ~2002-03-22. The rationale was to allow
robots and humans to change the media during a mount session.

Unfortunately this lead to file marks being written to potentially other
media at the beginning on drives that used the two file marks as EOM
pattern. In order for that to happen the media had to be removed after
data and at most one file mark had been written before removal.

The mount error message has been clarified and a warning about
potential data/file mark lossage on UNIT ATTENTION
during an active mount session with unfinished file marks has been
added.

While there, fix, but disable the commented SUN compatibility to write
final file marks by opening and immediately closing the device
in O_WRONLY mode. That code has not been working since around 1998.

It can now be enabled with options ST_SUNCOMPAT.

Additionally debug output coverage has been extended.

merge ktrace-lwp.

Sync with HEAD. Here we go again...

sync with -current

make the scsibus target/lun and the atapibus drive locators optional
(they already had default values; we could kill the [...=N] syntax
completely or at least have config(8) assume that a locator with
a default is optional)

sync with head.  xen and whitespace.  xen part is not finished.

Hi Perry!

nuke trailing whitespace

Fix the sync with head I botched.

Don't assume wdc-specific ATA / ATAPI code should be brought in if atabus
or atapibus are configured; use a separate wdc_common attribute to indicate
that the shared wdc code is also present.

Sync with HEAD

Make the ATA mid-layer appears as atabus, as proposed in
http://mail-index.netbsd.org/tech-kern/2003/09/25/0006.html
This adds a device (atabus) between IDE controllers and wd or atapibus, to
have each ATA channel show up in the device tree. Later there will be atabus
devices in /dev, so that we can do IOCTL on them.
Each atabus has its own kernel thread, to handle operations that needs polling,
e.g. reset and others.

Device probing on each bus it defered to the atabus thread creation.
This allows to do the reset and basic device probes in parallel, which reduce
boot time on systems with several pciide controllers.

Merge the geometry and cache handling code for all direct access and optical
devices, as it's general to all SCSI MMC devices.  In the process, remove
PQUIRK_NO_FLEX_PAGE.

Eliminate the separate ATAPI and SCSI attachments for "cd".

We only need a single attachment for uk at scsibus and atapibus.

Catch up to -current.

Define a "scsi_core" attribute.  Make the "scsi" attribute depend on
"scsi_core".  Make all the files previously selected by the "scsi"
attribute selected by the "scsi_core" attribute.  Give the "scsibus"
device the "scsi_core" attribute.

- convert usage of "defopt" to "defflag" where the relevant option does
  not support a value (e.g., it's to be used as "options FOO" instead of
  "options FOO=xxx"). options that take a value were converted to
  defparam recently.
- minor whitespace & formatting cleanups

Added the new defopt SCSI_OLD_NOINQUIRY; this is used instead
of sun2 to wrap code that conjures up INQUIRY responses for
certain specific old devices.

- replace "defopt" with "defparam" for options which must take a value,
  as config(8) will warn for value-less defparam options
- minor whitespace/formatting cleanup
- consolidate opt_tcp_recvspace.h and opt_tcp_sendspace.h into opt_tcp_space.h

Catch up to -current.

Add SDRETRIES and SD_IO_TIMEOUT option for sd.

Add an ATAPI front-end to the st driver. Completely untested for now,
but st at scsi should still work :)

Pull up the thorpej_scsipi branch to main branch.
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
  ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
  to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
  peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
  recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
  scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
  (no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
  set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
  the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
  will be requeued, or a REQUEST SENSE will be sent as appropriate.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Main changes to the scsipi code itself:
- add a scsipi_channel->type to allow umass to attach to both atapibus and
  scsibus. Will die when IDE is converted from ata_atapi_attach to
  scsipi_channel/scsipi_adapter
- Add a chan_defquirks to scsipi_channel so that adapters can pass a default
  set of quirks to be set for each device attached
- add adapt_getgeom and adapt_accesschk callbacks

revert previous change

remove SES driver

add SES device

add ST_MOUNT_DELAY options for st

Fixup the SC_DEBUG() stuff for the new world order.

Don't bring scsi/atapi common files in under the "atapi" attribute.
Bring them in under atapibus since they're not needed unless something
attached to an atapibus is also attached.
Tested on i386 and arm32.

Rename scsi_interpret_sense() to scsipi_interpret_sense() and move it from
scsi_base.c to scsipi_base.c. Rename the functions from scsi_verbose.c
too, and rename the file itself. Cleaup includes too (scsi_*.h should not
be #included in scsipi_*.h files, which are supposed to be
common to atapi and scsi).

Allow uk to attach at atapibus.

Merge bouyer-ide

 - sync with HEAD
 - better error detection and report for wd drives
 - better wddump() support
 - wdcwait() now takes a timout argument, so that we can honnor the
   timeout argument of scsipi cmds.

opt_scsiverbose.h now is opt_scsi.h and contains the defopted
SCSIVERBOSE and the new ST_ENABLE_EARLYWARN.

file files.scsipi was added on branch eeh-paddr_t on 1998-07-30 00:49:20 +0000

opt_scsiverbose.h now is opt_scsi.h and contains the defopted
SCSIVERBOSE and the new ST_ENABLE_EARLYWARN.

Commit changes to the IDE system in a branch. This allows a better separation
between higth-level and low-level (i.e. registers read/write) and generalize
the queue for all commands. This also add supports for IDE DMA.

Split out the verbose printing of scsi messages, so that user programs
can use the printing routines.

Remove "class" declarations, and add "devclass" declarations where
appropriate.  Fix several inconsistencies between device class and
attributes.  Mostly from Chris Demetriou.

add support for an ATAPI attachment for 'sd'.
fix 'cd' driver's NCD_SCSI bogosity (was using testing wrong macro!)
clean up in various ways:
* make common atapi_mode_{sense,select}() functions.
* put ATAPI data structures in more sensible headers, split up by
  device type.
* include headers a bit more carefully.
* pass flags to attachment-specific cd functions, and use them.
* get rid of SCSI bits in scsipi_base.h's scsipi_make_xs(), move
  them into the correct place in scsi_base.c.
* fix minor typo in struct name in scsipiconf.h (which was apparently
  never used except in a #define later in the same file).
* use __attribute__ to force 4-byte alignment for xs command store,
  so that architectures trying to bus_space_write_multi_N() (where
  N > 1) that data to a controller won't lose.
* clean up a few comments in typos, and make a few #defines easier to
  understand/maintain.
* rename cd_link.h to cdvar.h (via repository copy).  This is exactly
  what a 'var' file is supposed to be.

Adjust for changes to config.

Update marc-pcmcia branch from trunk.

Cosmetic changes to keep coding style consistency in this directory;

- Indent with tab of width 8.
- Use four column to indent continuation line.
- Fold long line if possible.
- Use return (xx) instead of return xx.
- Compare pointer against NULL instead of testing like boolean.
- Delete whitespace at the end of line.
- Delete whitespace in front of function call operator.
- Delete whitespace after cast.
- Dereference a pointer to function explicitly.
- Add an empty line after local variable declaration.
- Use NULL instead of (char *)0.
- Dont use block for single statement.

Update marc-pcmcia branch from trunk.

file files.scsipi was added on branch marc-pcmcia on 1997-08-27 23:33:06 +0000

Merge scsipi branch in the mainline. This add support for ATAPI devices
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.

Add missing arp tag for se driver.

Driver for the Cabletron EA41x SCSI Ethernet Adaptor, written by
Ian Dall <ian.dall@dsto.defence.gov.au>.  Converted to "new arp"
and some other (very) minor changes by me.

Merge in changes from Trunk

Fix typo in comment.

Slight adjustments for new version of ahc driver.

New device attachment scheme:

	- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

Add SCSI scanner support by Kenneth Stailey and Joachim Koenig-Baltes,
hacked a bit.  Needs more work.
