 1.29  16-Jan-2024  andvar Fix typos in word "particularly", in comments.
 1.28  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.27  24-Apr-2021  thorpej branches: 1.27.8;
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?).
 1.26  07-Mar-2014  skrll branches: 1.26.46;
Fix non-DIAGNOSTIC build
 1.25  27-Oct-2012  chs branches: 1.25.2;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.24  13-Nov-2010  uebayasi branches: 1.24.8; 1.24.18;
Don't pull in the whole uvm(9) API to access only PAGE_SIZE and
some other constants. These are provided by sys/param.h now.
 1.23  12-May-2009  cegger branches: 1.23.4;
struct device * -> device_t, no functional changes intended.
 1.22  12-May-2009  cegger struct cfdata * -> cfdata_t, no functional changes intended.
 1.21  28-Apr-2008  martin branches: 1.21.14;
Remove clause 3 and 4 from TNF licenses
 1.20  08-Apr-2008  cegger branches: 1.20.2; 1.20.4;
use aprint_*_dev and device_xname
 1.19  04-Jan-2008  ad branches: 1.19.6;
Start detangling lock.h from intr.h. This is likely to cause short term
breakage, but the mess of dependencies has been regularly breaking the
build recently anyhow.
 1.18  19-Oct-2007  ad branches: 1.18.2; 1.18.8;
machine/{bus,cpu,intr}.h -> sys/{bus,cpu,intr}.h
 1.17  04-Mar-2007  christos branches: 1.17.2; 1.17.14; 1.17.16; 1.17.20;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.16  16-Nov-2006  christos branches: 1.16.4;
__unused removal on arguments; approved by core.
 1.15  12-Oct-2006  christos - sprinkle __unused on function decls.
- fix a couple of unused bugs
- no more -Wno-unused for i386
 1.14  25-Mar-2006  thorpej branches: 1.14.8; 1.14.10;
Use device_parent().
 1.13  29-Jan-2006  dsl branches: 1.13.2; 1.13.4; 1.13.6; 1.13.8; 1.13.10;
Make almost everything #include <sys/bswap.h> instead of <machine/bswap.h>
The bswap.h and endian.h files are all rather incestuous, but I want to
get the constant folding stuff into one place - sys/bswap.h
 1.12  11-Dec-2005  christos branches: 1.12.2;
merge ktrace-lwp.
 1.11  27-Feb-2005  perry branches: 1.11.4;
nuke trailing whitespace
 1.10  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.
 1.9  18-Sep-2003  mycroft branches: 1.9.8; 1.9.10;
nluns should be 8, not 7.
 1.8  13-Jun-2003  thorpej branches: 1.8.2;
Add support for dynamic rescan of cache service logical drives, using
the ioctl issued by the ICP RAID management libraries (used by the
storcon and iirconfig tools). This requires some infrastructure changes:
* Add a "service callback" mechanism that the ld driver (cache service)
and the iopsp driver (raw service) can register with the icp parent.
Right now this callback allows the children to adjust their notion of
how many command openings are available.
* Add a mutex around the icp ioctl handler, allowing only one thread
to execute an ioctl at a time.
* Add a way to freeze the controller command queue. We stop all I/O
while processing rescans (due to the semantics of icp_cmd()).
* Make icp_cmd() work when !cold.
* Add detach support to ld@icp.
 1.7  13-May-2003  thorpej Add support for the user-generated command interface and event logging
required by the ICP-Vortex management tools. Many thanks to Achim Leubner
at ICP-Vortex for a few bug fixes and for testing.
 1.6  02-Oct-2002  thorpej Add trailing ; to CFATTACH_DECL.
 1.5  30-Sep-2002  thorpej Use CFATTACH_DECL().
 1.4  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.3  27-Sep-2002  provos remove trailing \n in panic(). approved perry.
 1.2  25-Apr-2002  ad branches: 1.2.6; 1.2.8;
Set xs->error = XS_SENSE in the appropriate spot.
 1.1  22-Apr-2002  ad Add a driver for ICP-Vortex GDT and Intel Storage RAID controllers. Parts
taken from OpenBSD. Test hardware kindly provided by Intel. This still needs
management bits, and doesn't support older controllers, but that shouldn't
be hard to fix.

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup

page option might cover that.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs. ("Protocol error: too many arguments")
 1.24.8.1  30-Oct-2012  yamt sync with head
 1.25.2.1  18-May-2014  rmind sync with head
 1.26.46.1  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.
 1.27.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
