 1.70  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.69  27-Jul-2021  thorpej branches: 1.69.2;
- Remove unused <sys/malloc.h> include.
- Rename ahb_ecb_phys_kv() to ahb_ecb_lookup().
- Remove a bogus comment.
 1.68  26-Jul-2021  thorpej - Type hygiene.
- Rename ahb_ecb::hashkey to ahb_ecb::ecb_dma_addr, and use that value
rather than recomputing it all the time.
 1.67  24-Jul-2021  thorpej Don't blindly establish our interrupt handler as IST_LEVEL. If the INTDEF
register has the INTHIGH bit set, the controller is going to keep the
line low when *not* asserting an interrupt, and since EISA level-tiggered
interrupts are active-low, this would result in a forever-interrupt-storm.

So, if INTHIGH is set in INTDEF, establish our interrupt handler as
IST_EDGE, which will program the EISA PIC to detect the interrupt on
the rising edge of the IRQ line.
 1.66  24-Apr-2021  thorpej branches: 1.66.2;
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?).
 1.65  27-Jan-2021  thorpej branches: 1.65.2;

 1.42  21-Feb-2005  thorpej branches: 1.42.4;
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.
 1.41  07-Dec-2004  thorpej branches: 1.41.2; 1.41.4;
Don't use "struct scsi_generic" in a hardware-defined structure. Instead,
use an array of 12 bytes. Check the incoming CDB to see that it will fit,
and print and error and fail the command if it won't.
 1.40  23-Aug-2004  thorpej - Use ANSI function decls and make use of static.
 1.39  02-Nov-2003  wiz branches: 1.39.4;
Fix some typos. From Tom Cosgrove via jmc@openbsd.
 1.38  02-Oct-2002  thorpej branches: 1.38.6;

 1.37  30-Sep-2002  thorpej Use CFATTACH_DECL().
 1.36  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.35  05-Apr-2002  bouyer Implement mstohz() as discussed on tech-kern, and use it in SCSI drivers
to convert xs->timeout to callout() parameter.
 1.34  15-Nov-2001  lukem don't need <sys/types.h> when including <sys/param.h>
 1.33  13-Nov-2001  lukem add RCSID
 1.32  25-Apr-2001  bouyer branches: 1.32.2;
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
 1.31  14-Nov-2000  thorpej branches: 1.31.2;
NBPG -> PAGE_SIZE
 1.30  12-Jul-2000  thorpej Fix a couple of LP64 problems (long -> int32_t).
 1.29  23-Mar-2000  thorpej branches: 1.29.4;
New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.
 1.28  30-Sep-1999  thorpej branches: 1.28.2;
Update for SCSPI changes.
 1.27  09-Dec-1998  thorpej Update for changed scsipi_xfer struct.
 1.26  05-Dec-1998  mjacob Update HBAs to incorporate the new max_lun property.
 1.25  19-Nov-1998  thorpej Adapt to the new scsipi_adapter interface.
 1.24  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.
 1.23  17-Aug-1998  mycroft Assign my copyrights to TNF.
 1.22  15-Aug-1998  mycroft Name some constants consistently between drivers.
 1.21  15-Aug-1998  thorpej Only map the amount of space the device actually occupies.

Part of PR #5279, Martin Musemann.
 1.20  04-Jul-1998  jonathan defopt DDB.
 1.19  08-Jun-1998  thorpej Nuke __BROKEN_INDIRECT_CONFIG.
 1.18  17-Feb-1998  thorpej - Perform all necessary bus_dmamap_sync() operations.
- Greatly simplify allocation and DMA mapping of the mailbox and ccbs.
- Be more robust against resource shortage errors, and report errors better.
 1.17  04-Feb-1998  thorpej Add offset and length parameters to bus_dmamap_sync(), used for specifiying
partial syncs of a DMA mapping.
 1.16  04-Feb-1998  thorpej Add dm_mapsize to bus_dmamap_t and rename BUS_DMAMEM_NOSYNC to
BUS_DMA_COHERENT.
 1.15  28-Jan-1998  thorpej Use offsetof() from libkern.h
 1.14  12-Jan-1998  thorpej Slight change to previous.
 1.13  12-Jan-1998  thorpej Adjust for config changes.
 1.12  04-Nov-1997  thorpej Implement a simple queueing mechanism that makes these drivers much
more robust in resource shortage situations, basically identical to
code I added to the "ahc" driver some time ago.

Thanks to Brad Spencer for the testing help.
 1.11  29-Oct-1997  thorpej When creating ecbs, be a little more informative about why we couldn't
should creation/initialization of a ecb fail. Also, don't panic in
these situations. Instead, simply return an error condition and allow
the caller to deal with it. It may be the case that we were able to
create one ecb what we can grab, and continue to hobble along.
 1.10  27-Aug-1997  bouyer branches: 1.10.4;
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.
 1.9  06-Jun-1997  thorpej branches: 1.9.2; 1.9.4;
Pull thorpej-bus-dma branch into mainline.
 1.8  28-Mar-1997  mycroft branches: 1.8.2;
Use a temporary data structure for holding probe information, rather than a
full softc.
 1.7  10-Dec-1996  thorpej branches: 1.7.2;
Fill in sc_link.max_target
 1.6  21-Oct-1996  thorpej New bus.h implementation/interface:
- No more distinction between i/o-mapped and memory-mapped
devices. It's all "bus space" now, and space tags
differentiate the space with finer grain than the
bus chipset tag.
- Add memory barrier methods.
- Implement space alloc/free methods.
- Implement region read/write methods (like memcpy to/from
bus space).
This interface provides a better abstraction for dealing with
machine-independent chipset drivers.
 1.5  13-Oct-1996  christos backout kprintf changes
 1.4  10-Oct-1996  christos printf -> kprintf, sprintf -> ksprintf
 1.3  19-Sep-1996  thorpej Correct two prototypes so that this compiles without DDB defined.
 1.2  07-Sep-1996  mycroft Oops. Copy out the right number of command bytes.
 1.1  01-Sep-1996  mycroft General cleanup, like other drivers.
 1.7.2.2  11-Dec-1996  mycroft From trunk:
General cleanup; fixes several bugs.
 1.7.2.1  10-Dec-1996  mycroft file ahb.c was added on branch netbsd-1-2 on 1996-12-11 05:06:56 +0000
 1.8.2.3  18-May-1997  thorpej Do the __BROKEN_INDIRECT_CONFIG dance.

 1.10.4.2  04-Nov-1997  thorpej Pull up from trunk: add a queueing mechanism to make this much more
robust in resource shortage conditions.
 1.10.4.1  29-Oct-1997  thorpej Pull up from trunk: be more verbose/robust about ecb allocation failure.
 1.28.2.6  22-Nov-2000  bouyer Sync with HEAD.
 1.28.2.5  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.
 1.28.2.4  01-Nov-1999  thorpej Fixup the SC_DEBUG() stuff for the new world order.
 1.28.2.3  26-Oct-1999  thorpej Update for:

Deal a little more gracefully with the fact that xfer mode parameters
are for the I_T Nexus, and make all xfer mode updates `async events'.
 1.28.2.2  20-Oct-1999  thorpej Eliminate sleeping from adapter routines.
 1.28.2.1  19-Oct-1999  thorpej Adapt to scsipi API changes.
