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.

Merge isaki-audio2 branch, the overhaul of audio subsystem.
- Interrupt-oriented system rather than thread-oriented.
- Improve stability, quality and performance.
- Split playback and record cleanly. Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism. The encoding/channels/frequency
conversions are completely handled in the upper layer. So the hard-
ware driver only converts its hardware encoding (if necessary).
- audio_hw_if changes:
- Obsoletes query_encoding and add query_format instead.
- Obsoletes set_params and add set_format instead.
- Remove drain, setfd, mappage.
- The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.
- ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced.
- cleanup config attributes: au*conv and mulaw.
- All hardware drivers should follow it (I've done as much as possible).

- dev/audio.c -> dev/audio/audio.c (rewritten)
- dev/audiovar.h -> dev/audio/audiovar.h

Misc updates to hopefully improve vidcvideo console usability:
* add virtual consoles by using wsdisplay_vcons
* make use of generic scrollback support for consoles
* enable colour support for vidcvideo consoles
* use the default NetBSD font, rather than picking a sony one
* make kernel output green, so it's obvious.

This was tested at 800x600 in 8bpp on an A7000+ and 2MB VRAM RiscPC.

Arrange things so that if MONITOR isn't defined in the kernel configration,
we use the standard mode list from videomode.c rather than one generated
by makemodes.awk. This is less useful than it might be since without a useful
frame rate from the bootloader we're likely to end up choosing a screen mode
that's either flickery or too fast for the monitor (or DRAM bandwidth).

Nothing in the tree uses NVIDCAUDIO or NVIDC, so stop generating them.

Finally remove the old, pre-wscons, acorn32 console code. This dated back
to RiscBSD and had been lurking in dark corners scaring people (mostly me)
for far too long. It will be missed, but not much, and I hope we can clear
up any fallout before 5.0.

While I'm in the area, also remove rpckbd(4), since pckbd(4) has

merge kent-audio1 branch, which introduces audio filter pipeline to the MI
audio framework


Summary of changes:

* struct audio_params
- remove sw_code, factor, factor_denom, hw_sample_rate,
hw_encoding ,hw_precision, and hw_channels. Conversion information
is conveyed by stream_filter_list_t.
- change the type of sample_rate: u_long -> u_int
- add `validbits,' which represents the valid data size in
precision bits. It is required in order to distinguish 24/32bit
from 24/24bit or 32/32bit.

* audio_hw_if
- add two parameters to set_params()
stream_filter_list_t *pfil, stream_filter_list *rfil
A HW driver should set filter recipes for requested formats
- constify audio_params parameters of trigger_output() and
trigger_input(). They represent audio formats for the hardware.
- make open() and close() optional
- add int (AUMODE_PLAY or AUMODE_RECORD) and audio_params_t parameters
to round_blocksize()

* sw_code is replaced with stream_filter_t.
stream_filer_t converts audio data in an input buffer and writes
into another output buffer unlike sw_code, which converts data in
single buffer.
converters in dev/auconv.c, dev/mulaw.c, dev/aurateconv.c,
dev/tc/bba.c, dev/ic/msm6258.c, and arch/arm/iomd/vidcaudio.c are
reimplemented as stream_filter_t

* MI audio
- audiosetinfo() builds filter pipelines from stream_filter_list_t
filled by audio_hw_if::set_params()
- audiosetinfo() returns with EINVAL if mmapped and set_params()
requests filters
- audio_write(), audio_pint(), and audio_rint() invoke a filter
pipeline.
- ioctl() for FIONREAD, AUDIO_WSEEK, AUDIO_GETIOFFS,
AUDIO_GETOOFFS, and audio_prinfo::{seek,samples} for
AUDIO_GETINFO handle values for a buffer nearest to userland.

* add `struct device *' parameter to ac97_attach()

* all of audio HW drivers follow audio_hw_if and ac97 changes

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?).

current_spl_level and interrupt state could be mangled.

Rewrite the ARM mutex implementation to be of the simple-mutex variety.
Because pre-v6 ARM lacks support for an atomic compare-and-swap, we
implement _lock_cas() as a restartable atomic squence that is checked
in the IRQ handler right before AST processing. (This is safe because,
for all practical purposes, there are no SMP pre-v6 ARM systems.)

This can serve as a model for other non-MP platforms that lack the
necessary atomic operations for mutexes (SuperH, for example).

Upshots of this change:
- kmutex_t is now down to 8 bytes on ARM; about as good as we can get.
- ARM2 systems don't have to trap and emulate SWP or SWPB for mutexes.

The acorn26 port is not updated by this commit to do the LOCK_CAS_CHECK.
That is left as an exercise for the port maintainer.

Finally, a few obvious little micro-optimisations like using LDR directly

bouncing via R0.

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?).

- 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.

The log2_bpp fields of the mode list generated by makemodes.awk weren't
used for anything. Rearrange things so that it doesn't any more, and
just produces an array of struct videomode. modedefs.c is looking
suspiciously much like videomode.c now.

Move calculation of a screen mode's frame rate out of makemodes.awk into
the kernel, removing an element from struct vidc_mode. The calculation
is a bit pointless at the moment anyway, since both bootloaders pass in
a constant 56, but that might get fixed one day.

Switch to using the MI struct videomode for storing VIDC video timings.
struct videomode doesn't have a way to record border widths (though I
wonder if VESA's "margins" are the same thing), so we now just treat them
as zero. Tested on my NC, which still seems to be working.

Fix an obvious typo.

Use portable | cat 1>&2 instead of > /dev/stderr. This allows this script

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?).

Allthough this patch doesn't look that much it adds a few things that were
on the port-acorn32's TODO list for quite some time :

- when the serial console is selected, don't exclude the screen
alltogether; currently the keyboard is still not attached but that might be
a configuration problem in the GENERIC console or a failure to explicitly
connect to a wsmux. This needs further investigation.

- create a framework for the display memory writeback on vsync for
StrongARM processors since they don't have a write-trough cache. This is to
solve the lazy screen update that is very evident in single user mode on
these processors; the cache isn't flushed/written back that often and parts
of the screen can thus be resident in the cache but not written out to
memory yet.

- clean up some loose ends in the code.

files still need a lot of cleaning up :( .... esp. the RC7500 support that
is still dormant in it; this needs either to be removed or split out for
RC7500's ``VIDC'' video/audio variant.

Apart from the RC7500 support wich is still in arch/arm32 the
iomd,vidc,riscpc and podulebus subdirectories of arch/arm32 can be removed.

This split still uses some small parts of arch/arm32 .... those are the MI
parts that haven't been moved yet.

Finally remove the old, pre-wscons, acorn32 console code. This dated back
to RiscBSD and had been lurking in dark corners scaring people (mostly me)
for far too long. It will be missed, but not much, and I hope we can clear
up any fallout before 5.0.

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.

branches: 1.3.8;
Include <machine/conf.h> for cdevsw function prototypes.

Move calculation of a screen mode's frame rate out of makemodes.awk into
the kernel, removing an element from struct vidc_mode. The calculation
is a bit pointless at the moment anyway, since both bootloaders pass in
a constant 56, but that might get fixed one day.

This is kernel-only now, so no need to check _KERNEL.

Switch to using the MI struct videomode for storing VIDC video timings.
struct videomode doesn't have a way to record border widths (though I
wonder if VESA's "margins" are the same thing), so we now just treat them
as zero. Tested on my NC, which still seems to be working.

Remove some prototypes and macros that aren't used any more.

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?).

When setting the FIFO preload, chose an entirely safe value rather than

When looking for a screen mode at startup, skip any interlaced and
doublescan modes, since vidcvideo doesn't support them.

If we can't find a screen mode matching the bootloader's frame rate, choose
the nearest one, rather than the first one with the same resolution. This
is likely to be useful when the bootloader finally passes a valid frame rate.
For now, it just favours flickery over non-functional.

Arrange things so that if MONITOR isn't defined in the kernel configration,
we use the standard mode list from videomode.c rather than one generated
by makemodes.awk. This is less useful than it might be since without a useful
frame rate from the bootloader we're likely to end up choosing a screen mode
that's either flickery or too fast for the monitor (or DRAM bandwidth).

The log2_bpp fields of the mode list generated by makemodes.awk weren't
used for anything. Rearrange things so that it doesn't any more, and
just produces an array of struct videomode. modedefs.c is looking
suspiciously much like videomode.c now.

Move calculation of a screen mode's frame rate out of makemodes.awk into
the kernel, removing an element from struct vidc_mode. The calculation
is a bit pointless at the moment anyway, since both bootloaders pass in
a constant 56, but that might get fixed one day.

remove trailing \n in panic(). approved perry.

Move over to using a 6:5:5 R:G:B palette in 16-bit display modes, and abstract
the palette generation to work with arbitrary numbers of bits.
This allows X to work after a fashion, since it tries to put the VIDC into
a 6:5:5 mode itself (which we ignore). Anything that actually tries to take
advantage of the DirectColor visual it offers will still be screwed, but I
hope such applications are rare.

Kill off vidcvideo_textpalette() again, but better.
This time, vidcvideo_stdpalette() uses vidcvideo_write(), as it should, and

generally broken anyway.
