 1.40  09-Feb-2024  andvar fix spelling mistakes, mainly in comments and log messages.
 1.39  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.38  24-Apr-2021  thorpej branches: 1.38.8;
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?).
 1.37  15-Sep-2020  mlelstv branches: 1.37.4;
max_devices is a 8bit value and zero is interpreted as 256. This value
can be reported by an mpt device emulated by VMware ESXi.
 1.36  08-May-2019  cnst branches: 1.36.2;
mpt(4): remove ENOTTY / noop implementation of bio(4) setstate

* All other bio(4) drivers either do or don't implement each command.

* This changes the returned error code, but it does not seem to matter,
as some bio(4) drivers always return ENOTTY in the default case, whilst
others always return EINVAL (e.g., both cac(4) and ciss(4) for setstate).
 1.35  05-Feb-2018  mrg branches: 1.35.4;
fixes for GCC 6.4:

- fix an indentation issue in radioioctl().
- fix an indentation issue in mpt_run_xfer().
- grep's printline() has some {} placement issues.
 1.34  30-Jan-2018  jakllsch Move mpt_disc_enable setting into is_scsi block.

The field is only 16 bits, and is only refered to in the is_scsi case.
 1.33  02-May-2016  christos branches: 1.33.10;
move scsipi_strvis -> libkern:strnvisx()
change the prototype to match userland
fix sizes of strings passed to it
 1.32  22-Jul-2015  hannken Adapter leaks requests when mpt_event_notify_reply() has to acknowledge
an event leading to "adapter resource shortage" messages when the scsipi
subsystem tries to use all adapt_openings.

Change mpt_ctlop() to free the request on event MPI_FUNCTION_EVENT_ACK.

Tested on a SunFire X4275 with Symbios Logic SAS1068E (1000:0058, rev. 4).
 1.31  28-Sep-2014  jmcneill branches: 1.31.2;

 1.30  28-Sep-2014  jmcneill for BIOCDISK_NOVOL, set bd_disknovol=true for any disk not associated with a volume
 1.29  27-Sep-2014  jmcneill implement BIOCDISK_NOVOL
 1.28  27-Sep-2014  jmcneill include vendor/product/rev info for volumes and their disks
 1.27  27-Sep-2014  jmcneill show "sd0" instead of "mpt0" for volume device name
 1.26  27-Sep-2014  jmcneill add bio(4) support
 1.25  08-Jul-2014  chs branches: 1.25.2;
fix a device/softc error.
remove some related glue that is no longer needed.
 1.24  17-Apr-2014  christos CID/1203197: NULL deref
 1.23  17-Apr-2014  christos CID 1203189: Null deref.
 1.22  15-Apr-2014  buhrow Checking in cosmetic changes -- no functional change.
(Suggestions made by Taylor Campbell)
 1.21  11-Apr-2014  buhrow Fix up some KNF errors.
 1.20  01-Apr-2014  buhrow branches: 1.20.2;


Checking in changes to improve error handling. Specifically:

- if commands timeout, clear the queues to the the card and perform a soft
reset on the LSI hardware since when these timeouts occur, the LSI firmware
is not graceful about recovering at all.

- Recover gracefully from more kinds of errors using the same recovery
mechanism listed above.

Also, implement mpt_ioctl() to handle bus reset requests from scsictl(8).
 1.19  23-Sep-2012  chs branches: 1.19.2;
set chan_bustype correctly.
 1.18  18-Mar-2012  martin branches: 1.18.2;
Split device_t
 1.17  30-Jan-2012  mhitch branches: 1.17.2;
Allow adapters with SAS/SATA or FC devices to use tagged queuing by the scsipi
layer. Can improve write performance on SAS adapters under certain conditions
when the logical drive does not have write caching enabled. Also need to
reserver a couple of slots for commands for the driver to use - stops the
adapter shortage messages. Multiple commands can now cause QUEUE_FULL events,
so add that to the events handled, currently just ignoring it. Changes
based on the thread http://mail-index.netbsd.org/tech-kern/2011/02/08/msg009946.html.
cvs: ----------------------------------------------------------------------
 1.16  17-Jul-2011  joerg branches: 1.16.2; 1.16.6;
Retire varargs.h support. Move machine/stdarg.h logic into MI
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.
 1.15  28-Apr-2010  chs add byte-swapping so that this works on BE platforms.
the logic is based on the current freebsd driver.
fixes PR 42870.
 1.14  08-Apr-2008  cegger branches: 1.14.4; 1.14.14; 1.14.24; 1.14.26;
use aprint_*_dev and device_xname
 1.13  04-Aug-2007  tron branches: 1.13.22; 1.13.24;
Fix some KNF glitches pointed out by Garrett D'Amore.
 1.12  27-Jul-2007  tron branches: 1.12.4;
Add support for newer SAS and similar devices to mpt(4). Tested with
the LSI SAS1064 in a Sun x4200 server.

These enhancements were developed by Garrett D'Amore and contributed
to NetBSD by the TELES AG.
 1.11  04-Mar-2007  christos branches: 1.11.2; 1.11.10;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.10  11-Dec-2005  christos branches: 1.10.24; 1.10.26; 1.10.30;
merge ktrace-lwp.
 1.9  27-Feb-2005  perry branches: 1.9.2; 1.9.4; 1.9.12; 1.9.14;

 1.8  10-Apr-2004  briggs branches: 1.8.4; 1.8.6;
Set the DMA SGL length correctly if the DMA request must be chained because
it is too large to fit in one SGL.
Fix from HITOSHI Osada <QFH02545 (at) nifty.com> in response to PR kern/24967.
 1.7  14-Jul-2003  lukem branches: 1.7.2;
add missing __KERNEL_RCSID()
 1.6  01-May-2003  thorpej branches: 1.6.2;
Free the mpt request structure before calling scsipi_done(), as
scsipi_done() may start another command which needs the request
structure being freed.

Patch from Stephan Uphoff, modified slightly by me.
 1.5  23-Apr-2003  tls Correct use of MAXBSIZE where MAXPHYS was intended. This is a necessary
first step towards per-device MAXPHYS, and has the beneficial side effect
of allowing clustering to MAXPHYS even on systems that need to run with
a reduced MAXBSIZE to get more metadata buffers.
 1.4  16-Apr-2003  thorpej In the polling case, don't call mpt_timeout() twice.
 1.3  16-Apr-2003  thorpej mpt_dma_mem_alloc(): If we fail, only destroy request DMA maps that
were actually created.
 1.2  16-Apr-2003  thorpej Correctly sync the MPT request buffers, and remove BUS_DMA_COHERENT
from the mapping of those buffers.
 1.1  16-Apr-2003  thorpej Device driver for the LSI Logic Fusion-MPT based SCSI and Fibre Channel
adapters. Currently supports:

* LSI 53c1030 Ultra320 SCSI
* LSI FC909, FC909A, FC919, and FC929 Fibre Channel

Ported from the FreeBSD "mpt" driver, written by Greg Ansley. Thanks
to Frank van der Linden for testing and some bug finding.

physio (I/O to raw devices); needs more doing to get it going with the
filesystems, but it shouldn't damage data.

All work's been done on amd64 so far. Not hard to add support to other
ports. If others want to pitch in, one very helpful thing would be to
sort out when and how IDE disks can do 128K or larger transfers, and
adjust the various PCI IDE (or at least ahcisata) drivers and wd.c
accordingly -- it would make testing much easier. Another very helpful
thing would be to implement a smart minphys() for RAIDframe along the
lines detailed in the MAXPHYS-NOTES file.
