 1.39  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.38  31-Jul-2021  andvar branches: 1.38.2;
fix more typos in style found one in file - check/fix them all.
 1.37  24-Apr-2021  thorpej branches: 1.37.2;
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?).
 1.36  11-Mar-2016  tsutsui branches: 1.36.32;
Properly zero out struct fb_devconfig, including rasops_info.

Fix panic after wsconscfg(8) from serial console, caused by

 1.35  26-Mar-2014  christos branches: 1.35.4; 1.35.6; 1.35.10;
kill sprintf
 1.34  11-Jan-2012  macallan branches: 1.34.6; 1.34.10;
adjust for wsfont_find() change
 1.33  19-Jul-2011  dyoung branches: 1.33.2; 1.33.6;
Change <machine/bus.h> to <sys/bus.h> throughout.

Split bus.h -> bus_{defs,funcs}.h.

Mark dreamcast/bus.h obsolete.
 1.32  21-May-2011  tsutsui Move several static wsdisplay variables into proper device specific structures
to resolve XXX comments. Tested on GXemul.
 1.31  26-Jan-2011  tsutsui Add proper prefix to structures.
 1.30  24-Oct-2010  tsutsui branches: 1.30.2; 1.30.4;
- make local functions/variables static
- export more cons(9) functions in pvrvar.h
 1.29  20-Oct-2010  tsutsui Split device_t/softc.
 1.28  19-Jun-2010  tsutsui Add WSDISPLAYIO_LINEBYTES, required by Xorg wsfb server.
 1.27  15-May-2010  tsutsui Clear RI_NO_AUTO in actual attach functions during autoconf(9)
for console devices that set the flag during consinit().
 1.26  15-May-2010  tsutsui Set RI_NO_AUTO in ri_flg if pvr_getdevconfig() is invoked from cninit.
Tested on gxemul.
 1.25  26-May-2008  nisimura branches: 1.25.18; 1.25.20;
- assign 2 clause TNF license to the files cited as my ownership.
- abandon and remove my copyright notice from the three files were
copied in order to adapt HW I don't have; pvr.c, pm.c and stic.c
 1.24  04-Mar-2007  christos branches: 1.24.40; 1.24.42; 1.24.44; 1.24.46;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.23  14-May-2006  elad branches: 1.23.14;
integrate kauth.
 1.22  12-Apr-2006  jmmv Add an extra cookie to the ioctl and mmap wsdisplay accessops that points
to the screen on which they are being called. The driver cannot guess
this by itself but it is needed to implement, at least, the getwschar and
putwschar functions in the correct place. There are no functional changes
yet.

Tested on i386 (vga, vga_raster, machfb, vesafb), macppc and sparc64.
Suggested and reviewed by macallan@.
 1.21  24-Dec-2005  perry branches: 1.21.4; 1.21.6; 1.21.8; 1.21.10; 1.21.12;
Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.
 1.20  11-Dec-2005  christos merge ktrace-lwp.
 1.19  19-Feb-2005  tsutsui branches: 1.19.6;
- u_intNN_t -> uintNN_t
- more ANSI function decls
- sone KNF
 1.18  10-Dec-2003  tsutsui branches: 1.18.8; 1.18.10;
Add WSDISPLAYIO_VIDEO_{ON,OFF} support for WSDISPLAYIO_SVIDEO ioctl.
Patch from Yasushi Oshima.
 1.17  02-Oct-2002  thorpej branches: 1.17.6;
Use CFATTACH_DECL().
 1.16  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.15  27-Sep-2002  thorpej When in a match routine, the cfdata we're passed always references
our own cfdriver, so don't bother comparing the names, since they
will always match.
 1.14  06-Sep-2002  gehenna Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
 1.13  04-Jul-2002  junyoung alloc_attr -> allocattr

Approved by Matthias Drochner.
 1.12  03-May-2002  thorpej branches: 1.12.2; 1.12.6;
De-obfuscate somewhat; define and use register bit constants, etc.
 1.11  24-Mar-2002  uch adapted to new interrupt code and shb changes.
 1.10  17-Mar-2002  atatat Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.
 1.9  13-Mar-2002  ad Reorganise the wsfont stuff slightly so that multiple display adapters
with different bit/byte order requirements can co-exist happily.
 1.8  05-Mar-2001  marcus branches: 1.8.4;
Off-by-one error on v_absolute_size fixed.
 1.7  04-Mar-2001  marcus Made it possible to mmap the frame buffer.
 1.6  19-Feb-2001  marcus PAL support...
 1.5  02-Feb-2001  thorpej branches: 1.5.2;
Report the VGA/NTSC RGB/composite mode of the display.
 1.4  01-Feb-2001  thorpej New PowerVR display driver, based on the TURBOchannel "cfb"
driver by Tohru Nisimura (a very good framework for a FB driver,
BTW!), using bits of Marcus's original driver for the hardware
access.

The main advantage of this version is that is uses rasops (which
is faster than the rcons stuff) and wsfont, so you can select the
console font in the kernel config file. Using the BOLD8x16 font,
you get an 80x30 console (vast improvement compared to the Gallant12x22
font).
 1.3  21-Jan-2001  marcus Corrected license text.
 1.2  21-Jan-2001  christos knf, some symbolic constants would be nice [pvrreg.h]
