Remove rounding by 4 bytes on round_blocksize().
For drivers which supports only 16bit * 2channels sampling,
rounding by 4 bytes no longer meaningful.

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).

Some file paths are changed:
- dev/audio.c         -> dev/audio/audio.c (rewritten)
- dev/audiovar.h      -> dev/audio/audiovar.h
- dev/audio_dai.h     -> dev/audio/audio_dai.h
- dev/audio_if.h      -> dev/audio/audio_if.h
- dev/audiobell.c     -> dev/audio/audiobell.c
- dev/audiobellvar.h  -> dev/audio/audiobellvar.h
- dev/mulaw.[ch]      -> dev/audio/mulaw.[ch] + dev/audio/alaw.c

Move dev/audio_if.h -> dev/audio/audio_if.h

Remove obsoleted methods in audio_hw_if.
- drain: is handled in audio upper layer now.
- mappage: is handled in audio upper layer now.
- setfd: no one uses and it's meaningless now.

Remove unnecessary header file.

Remove dev/auconv.[ch].
 Now it is handled in dev/audio/audio.c and dev/audio/linear.c.
Remove dev/mulaw.h.
 It already have been just a link to dev/audio/mulaw.h in this
 branch.

Adapt ad1848/cs4231 families to audio2.

Use C99 style struct initializer to audio_hw_if.

- Remove extra spaces and tabs.
- KNF.

split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.

Merge jmcneill-audiomp3 branch, which is derived from ad-audiomp2. From
the original ad-audiomp branch notes:

  Add MP locking to the audio drivers.

  Making the audio drivers MP safe is necessary before efforts
  can be made to make the VM system MP safe.

  The are two locks per device instance, an ISR lock and
  a character device lock. The ISR lock replaces calls to
  splaudio()/splx(), and will be held across calls to device
  methods which were called at splaudio() before (e.g.
  trigger_output). The character device lock is held across
  calls to nearly all of the methods, excluding some only
  used for initialization, e.g. get_locks.

Welcome to 5.99.57.

get rid of unused 'powerstate' callback in audio_hw_if

port ad-audiomp2 branch changes to 5.99.56
todo:
 - port ad-audiomp2 pcppi changes
 - these drivers need to be fixed:
   - emuxki
   - gcscaudio
   - hdafg
   - uaudio
   - umidi
   - MD audio drivers

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
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.

PR# 32473: GUS PnP audio device seems to be broken in NetBSD 3.0
We now need to call isa_drq_alloc to reserve DMA channel(s) for ISA
devices.
Thanks to Ben Collver for testing the patch for me!

Catch up with -current. Fix some bogons in the sparc64 kbd/ms
attach code. cd18xx conversion provided by mrg.

Catch up to -current.

Add a new optional method, dev_ioctl, to the audio hardware driver interface.
It is called when an unrecognized ioctl() is performed on a device,
thus allowing ioctl()s that frob the hardware driver (like loading
microcode).

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Add a new function call to the ISA DMA API: isa_dmamaxsize(), which returns
the maximum transfer size for the specified DMA channel.  Make all clients
of ISA DMA use this call to determine their maximum transfer size.

Pull up revision 1.14 (requested by wiz):
  Fix a problem preventing GUS P&P sound-card from working.

Sync w/ -current.

Make it possible for this driver tp work again.
From Thomas Klausner - wiz@danbala.tuwien.ac.at

Reject variant numbers which are too large (so that a new version of isapnpdevs
with an old driver will not lose mysteriously).

Update callers of isapnp_devmatch().

Update comments.

Pass the direction to the allocm and round_buffersize methods.
Some drivers need this to properly allocate DMAable memory.

Create a master list of pnp logical and compatibility device codes instead
of hard-coding it into each driver and use a centralized probe function.

Nuke __BROKEN_INDIRECT_CONFIG.

Adjust for the changes to the ISA DMA API.

Adjust for config changes.

make it compile without "__BROKEN_INDIRECT_CONFIG"

Pull rev 1.4 up from trunk (augustss)

Make sure isapnp_config() runs before we allocate the DMA channels.

Make the audio API (almost) SunOS compatible.
The changes is to allow some limited mixer manipulation through
the audio device (instead of the mixer device).
This rendered 4 methods in audio_hw_if unused so garbage collect these.

Update marc-pcmcia branch from trunk.

file gus_isapnp.c was added on branch marc-pcmcia on 1997-10-14 10:24:12 +0000

Fix tipo inherited from old version of TNF copyright template.
