 1.42  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.41  24-Apr-2021  thorpej branches: 1.41.8;
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?).

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.

Just before the merge syssrc has been tagged with thorpej_scsipi_beforemerge
 1.25  10-Jan-1999  tron branches: 1.25.8; 1.25.20;
Don't use void pointer for arithmetic.
 1.24  05-Dec-1998  mjacob Update HBAs to incorporate the new max_lun property.
 1.23  19-Nov-1998  thorpej Adapt to the new scsipi_adapter interface.
 1.22  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.
 1.21  12-Jan-1998  thorpej Adjust for changes to config.
 1.20  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.
 1.19  23-Dec-1996  veego branches: 1.19.8; 1.19.10;
Get rid of __BROKEN_INDIRECT_CONFIG.
 1.18  10-Dec-1996  thorpej Fill in sc_link.max_target
 1.17  13-Oct-1996  christos backout previous kprintf change
 1.16  10-Oct-1996  christos printf -> kprintf, sprintf -> ksprintf
 1.15  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.
 1.14  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).
 1.13  21-Apr-1996  veego - Cleanup for -Wall and -Wstrict-prototypes
- Added support for multiple floppy drives
- CyberVision64:
- has now a real console mode
- another bugfix for boards with the new S3 chip
- Ariadne:
- fixed crashes with aeput (mbuf failure)
 1.12  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.
 1.11  15-Mar-1996  mhitch Correct 53c710 initialization for the A4000T. Remove the A4000T probe
debugging output.
 1.10  16-Sep-1995  chopps Add minimal dumpfile support.
Fix a bug in pt_enter_ptpage which caused MMU faults on low-mem conditions.
Change siop drivers to better handle sync.
Remove diag. done for ide -- its redundant as the ROM does similar.
fixed ite_filter to not panic if typing before the device is fully setup
All thanks to osymh@gemini.oscs.montana.edu (Michael L. Hitch)
 1.9  18-Aug-1995  chopps SCSI disconnects: siop from osymh@gemini.oscs.montana.edu (Michael L. Hitch)
and sbic from "Eduardo E. Horvath eeh@btr.com" <eeh@btr.btr.com>

Other cleanup (remove cpu040) and enabling IVS A500 support
from osymh@gemini.oscs.montana.edu (Michael L. Hitch)
 1.8  12-Feb-1995  chopps Many changes from osymh@gemini.oscs.montana.edu (Michael L. Hitch)
Now use amiga HW for soft interrupts, non-contig options (2 or many chunks),
interrupt handler lists, 4066 ethernet, 1291 scsi, option to defer level 6
interrupts to level 4 (deal with icky built-in serial port)
 1.7  05-Jan-1995  chopps catchup with scsi changes from osymh@gemini.oscs.montana.edu (Michael L. Hitch)
 1.6  28-Dec-1994  chopps consolidate the zbusses. le support for multiple tx buffs and full use of 32k
RAM. AGA dbl PAL mode added for console. Many changes to siop--most not
yet done. All from osymh@gemini.oscs.montana.edu (Michael L. Hitch)
 1.5  01-Dec-1994  chopps bring up to current. change sun to sunos. handle changes in device
open params and autoconf match function params.
 1.4  26-Oct-1994  cgd new RCS ID format.
 1.3  16-Jun-1994  chopps fix boot diag output.
 1.2  14-Jun-1994  chopps don't flush cache on context switches for 040's, reduce flushing
on dma operations. code from me and Michael Hitch
 1.1  12-May-1994  chopps new scsi siop drivers and zthreebus support from
osymh@gemini.oscs.montana.edu (Michael L. Hitch)
 1.19.10.1  27-Aug-1997  thorpej Update marc-pcmcia branch from trunk.
 1.19.8.1  01-Jul-1997  bouyer Updates for new scsipi subsystem. Actally known to work on i386 and sparc.
 1.25.20.1  21-Jun-2001  nathanw Catch up to -current.
 1.25.8.1  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.

I updated the amiga SCSI drivers, but completely untested yet (may not even
compile)
 1.26.8.3  18-Oct-2002  nathanw Catch up to -current.
 1.26.8.2  28-Feb-2002  nathanw Catch up to -current.
 1.26.8.1  25-Apr-2001  nathanw file wesc.c was added on branch nathanw_sa on 2002-02-28 04:07:02 +0000
 1.26.2.2  10-Oct-2002  jdolecek sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work

 1.40.52.1  21-Mar-2021  thorpej Give config_found() the same variadic arguments treatment as
config_search(). This commit only adds the CFARG_EOL sentinel
to the existing config_found() calls. Conversion of config_found_sm_loc()
and config_found_ia() call sites will be in subsequent commits.
 1.40.28.1  27-Apr-2017  pgoyette Restore all work from the former pgoyette-localcount branch (which is
now abandoned doe to cvs merge botch).

The branch now builds, and installs via anita. There are still some
problems (cgd is non-functional and all atf tests time-out) but they
will get resolved soon.
 1.40.18.2  20-Jul-2016  pgoyette Redo previous. Rather than separately extracting the device_t, we can
rely on sc->sc_dev when we need to call device_release().
 1.40.18.1  19-Jul-2016  pgoyette Instead of repeatedly typing the conditional initialization of the
.d_localcount members in the various {b,c}devsw, define an initializer
macro and use it. This also removes the need for defining new symbols
for each 'struct localcount'.

As suggested by riastradh@
 1.41.8.1  03-Aug-2021  thorpej Adapt to CFARGS().
