	sys/dev/ic/dc503reg.h: revision 1.1

Port rasops'fied smg(4) framebuffer driver for VS3100 from OpenBSD/vax.

This allows using more fonts other than 8x15 pixels on smg(4).
Tested on my VAXstation 3100/m30.

Note the bitorder of smg(4) VRAM is LSB first (i.e. LSBit is the
most left side pixel) and this requires more complicated changes
to bitmask ops in MI rasops(9) because several LE machines have
VRAMs whose MSBit is connected to the most left side pixel,
but for now I prepared smg(4) specific putchar and cursor ops
based on old luna68k omrasops.

Add a support for gpx(4) color framebuffer found on VAXstation 3100.

Ported from OpenBSD/vax. Note smg(4) monochrome onboard framebuffer
driver is also changed attached only if gpx(4) is not installed
or flags 1 is specified in config files, as OpenBSD did.

Tested on my VAXstation 3100/m30 with and without 8bpp gpx(4).

Merge thorpej-cfargs2.

Adapt to CFARGS().

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?).

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.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

sync with head - hopefully this will work

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@.

merge ktrace-lwp.

Sync with HEAD. Here we go again...

Now that the wsfont fonts are made static, we can no longer
reference the fonts directly (which was actually a wrong thing
to try to do).  Instead, convert to using the wsfont API to
look for a 8x15 font, and use it if found.

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.

(CVS: It's not just a program. It's an adventure!)

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.

A i386 GENERIC kernel compiles without the siop, ahc and bha drivers

siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Un __P.

Pull up mmap paddr_t/off_t changes from trunk.

Change the kernel mmap interface so that the offset to map is an
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes.  Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".

Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

Fix spelling error.

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.

Don't detect glass tty if the machine is a workstation.
Hint from Thomas Seidmann.

Change vsbus to take a locator for all devices.
Figure out interrupt vector/mask on vsbus by forcing all devices to
generate interrupts in the match routine, like on unibus.

unsigned int -> int.

change the "mapchar" interface to return a "quality" or "match level"
arguments which allows to find approximations for characters which are
not present in a font

Another giant change: Allocate register space dynamic instead of compiled-in.
This is done on a physical page size basis, instead of virtual (as the
(on vax yet non-existing) bus_* routines does). This is similar to the
way uba allocation is done.

remove dummy "load_font" entries

blkclr -> memset.

fix problems in many d_mmap routines:
	- returned EOPNOTSUPP rather than -1.
