 1.70  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.69  24-Apr-2021  thorpej branches: 1.69.8;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Shadowing and const fixes.
 1.58  21-Feb-2005  thorpej Part 1 of a cleanup pass over the SCSI subsystem. The aim is to name
everything "scsi_*", since we really are talking about the SCSI command
set, ATAPI transport not withstanding. Improve the names of many structures,
and prepend "SCSI_" onto all SCSI command opcodes. Place items described
by the SCSI Primary Commands document into scsi_spc.h.

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.

 1.46  12-Dec-1999  scottr branches: 1.46.6;
Replace references to PGOFSET with m68k_trunc_page() and m68k_page_offset(),
as appropriate.
 1.45  30-Sep-1999  thorpej branches: 1.45.2; 1.45.8;
Update for SCSIPI changes.
 1.44  05-Dec-1998  mjacob branches: 1.44.4;
Update HBAs to incorporate the new max_lun property.
 1.43  19-Nov-1998  thorpej Adapt to the new scsipi_adapter interface.
 1.42  10-Oct-1998  thorpej Garbage-collect the open_target_lu and close_target_lu entry points from
struct scsipi_adapter; they were not used.

Add a scsipi_ioctl entry point to struct scsipi_adapter. This will be
used to issue ioctl commands to the host adapters.

Inspired by PR #6090, from Matt Jacob.
 1.41  02-Jul-1998  wrstuden Another printf("%:"...) bites the dust (->vprintf(...))
 1.40  12-Jan-1998  thorpej Update for changes to config.
 1.39  27-Aug-1997  bouyer 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.
 1.38  19-Dec-1996  scottr branches: 1.38.8; 1.38.10;
Clean up a few bogons+typos introduced in the removal of the broken indirect
config code.
 1.37  16-Dec-1996  scottr Convert all foo_match() functions to use a `struct cfdata *' for their
second argument. The NuBus autoconfig code had to be reorganized as a
result of this, and looks much more like a directly-attached bus now.
These changes eliminate __BROKEN_INDIRECT_CONFIG.
 1.36  10-Dec-1996  thorpej Fill in sc_link.max_target
 1.35  13-Oct-1996  christos backout previous kprintf change
 1.34  11-Oct-1996  christos printf -> kprintf, sprintf -> ksprintf
 1.33  28-Aug-1996  cgd (1) set scsi_link channel to either the appropriate channel (if a
multi-channel driver), or to SCSI_CHANNEL_ONLY_ONE if a
single-channel driver.
(2) use scsiprint() rather than a locally-defined autoconfig print
function, and kill any locally-defined print function.
 1.32  27-Aug-1996  cgd change cfprint_t type definition to take a const char *, rather than
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
 1.31  23-Jun-1996  briggs Add a comment about the last change.
 1.30  07-Jun-1996  briggs Wait longer (2.5 sec) in wait_req_true/false. Some targets take a long time.
 1.29  22-May-1996  briggs Get rid of compiler warning if DBG_PID is not defined.
 1.28  06-May-1996  briggs branches: 1.28.4;
Update to something closer to the atari port.
 1.27  05-May-1996  briggs Prototype for -Wall -Wstrict-prototypes -Wmissing-prototypes -Wno-uninitialized
Also change the device probing scheme to use something a bit more rational.
A current side-effect is that nubus cards are double-mapped. I expect
to fix that shortly.
Also change splclock() to block everything but serial hardware interrupts.
 1.26  30-Mar-1996  christos Change %r -> %: as for recursive printf's
 1.25  29-Mar-1996  briggs Fix minor oversight in a sanity check--caught by Jason, I think, and reported
by Scott.
 1.24  20-Mar-1996  scottr Fix a long-standing bug uncovered by the new device attachment
model. Thanks to Jason Thorpe for the fix (fixed PR 2235).
 1.23  17-Mar-1996  thorpej 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.
 1.22  07-Mar-1996  briggs Fix a typo in last.
 1.21  07-Mar-1996  briggs Disable SCSI linked commands, but allow kernel option to override.
 1.20  19-Feb-1996  briggs Update to latest Atari driver, but with some local modifications.
 1.19  03-Feb-1996  briggs Move debugging defines, etc. into mac68k5380.c and use them instead of
something similar but different. Make a few cosmetic changes.
 1.18  24-Jan-1996  briggs Patch a few of the holes in the machine-dependent part of this driver.
Sync the m.i. part with the Atari.
 1.17  06-Jan-1996  briggs Fix from Paul Goyette for off-by-one error.
 1.16  06-Jan-1996  briggs Bring in a few changes from Atari port.
Add support from Paul Goyette for keeping more than just the last 2
states when debugging.
 1.15  13-Dec-1995  briggs Fix from Paul Goyette to disable linked commands on drives that
reject them for simple commands. Leo W. reports that this does
not work for some systems. It's better than what we have now,
though. From Paul Goyette <paul@pgoyette.bdt.com>.
 1.14  04-Dec-1995  briggs Fix from Paul Goyette (paul@pgoyette.bdt.com) for drives that don't grok
linked commands.
 1.13  01-Dec-1995  briggs cmdlen-2 is right for the last byte of the command. Ifdef out for right now,
though, as some devices apparently don't support linked commands and will
reject commands that have the link bit set in them.
 1.12  30-Nov-1995  briggs Put the link flag in the right place.
Pointed out by Paul@pgoyette.bdt.com (Paul Goyette).
 1.11  31-Oct-1995  briggs Pull in all but one of Leo's changes from the atari copy.
 1.10  08-Oct-1995  briggs branches: 1.10.2;
Pick up changes from leo's latest version.
 1.9  02-Oct-1995  briggs Change to allow nack_message() to take an argument and send
MSG_REJECT_MESSAGE instead of MSG_ABORT when we get an extended message.
This allows a DEC drive to work when it attempts to negotiate synch.
transfers on us.
 1.8  18-Sep-1995  briggs Do not define MIN_PHYS here--it is m.d..
 1.7  16-Sep-1995  briggs Sync. with atari ncr5380.c -- mainly whitespace changes.
 1.6  16-Sep-1995  briggs Rename scsi_main_irq() to pdma_ready().
Missed a few ATNs in last patch. (pointed out by Leo).
Raise timeout from 100 to 1000. From Leo.
 1.5  15-Sep-1995  briggs As Leo pointed out, my last change was not safe. This one should be.
I added two new bitfields to ncr_softc. They flag which devices have
been selected, and which ones have failed to go to message out when
selected with ATN. If a target fails to go to message out the first
time it is selected, it goes into the latter bitfield. If it fails
thereafter, we treat it as we did before.
 1.4  14-Sep-1995  briggs Gah... The Asante SCSI/ethernet box doesn't answer the ATN request
for a 'MESSAGE OUT' phase, so add support in scsi_select() for the
phase to be either 'MESSAGE OUT' or 'COMMAND'.
 1.3  12-Sep-1995  briggs Updates from Leo's changes in the atari port.
 1.2  05-Sep-1995  briggs Remove infinite loop per Leo and Mycroft.
 1.1  03-Sep-1995  briggs Make a local copy of the atari m.i. scsi driver sources for the time
being. Some people aren't supping arch/atari and this allows those
people to get the sources.
 1.10.2.2  31-Oct-1995  briggs Bring in version from HEAD.
 1.10.2.1  16-Oct-1995  briggs Get rid of an 'if' in reselect() that causes a hang for me--pointed out by
Leo and Mattias(sp?).

 1.45.2.1  20-Nov-2000  bouyer 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.
