Drop 512 bytes limit on auvia_round_blocksize().

This fixes attach on 6 channels device.
PR kern/55017.

round_blocksize must return a multiple of the framesize.
aucc(4) supports 3 channels mode.

round_blocksize must return a multiple of the framesize
even if passed blocksize is greater than the upper limit.

round_blocksize must return a multiple of the framesize.

It's not divisible when blk=GCSCAUDI_PRD_SIZE_MAX and channels=4.
round_blocksize must return a multiple of the framesize
even if 6 channels mode.

I believe that keeping "good alignment" is just a wish, not constraint.

Clean get_props().
- Make get_props() return AUDIO_PROP_{PLAYBACK,CAPTURE} properly.
  This eliminates need for audio.c to take care of such (old)
  drivers which don't return both of PLAYBACK and CAPTURE.
- All get_props() doesn't need to return AUDIO_PROP_MMAP.
  It is handled in the audio layer now.

Don't return the raw audio formats; return the ones after we disabled some
of them because the device does not support them. Fixes panic in virtualbox.

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/audiobell.c     -> dev/audio/audiobell.c

- dev/mulaw.[ch]      -> dev/audio/mulaw.[ch] + dev/audio/alaw.c

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

Adapt to audio2.
- Correct frequency_type in modem_audio_format.
- {spdif,modem}_audio_format in my previous commit (in this branch)
  was also wrong. :(

Be a little more clear and consistent about harvesting entropy from devices:

1) deprecate RND_FLAG_NO_ESTIMATE

2) define RND_FLAG_COLLECT_TIME, RND_FLAG_COLLECT_VALUE

3) define RND_FLAG_ESTIMATE_TIME, RND_FLAG_ESTIMATE_VALUE

4) define RND_FLAG_DEFAULT: RND_FLAG_COLLECT_TIME|
   RND_FLAG_COLLECT_VALUE|RND_FLAG_ESTIMATE_TIME

5) Make entropy harvesting from environmental sensors a little more generic
   and remove it from individual sensor drivers.

6) Remove individual open-coded delta-estimators for values from a few
   places in the tree (uvm, environmental drivers).

7) 0 -> RND_FLAG_DEFAULT, actually gather entropy from various drivers
   that had stubbed out code, other minor cleanups.

Add some pre-processor magic to verify that the type of the data item
  passed to sysctl_createv() actually matches the declared type for
  the item itself.
In the places where the caller specifies a function and a structure
  address (typically the 'softc') an explicit (void *) cast is now needed.
Fixes bugs in sys/dev/acpi/asus_acpi.c sys/dev/bluetooth/bcsp.c
  sys/kern/vfs_bio.c sys/miscfs/syncfs/sync_subr.c and setting
  AcpiGbl_EnableAmlDebugObject.

put back IPL_AUDIO and splaudio(), at the request of rmind.  they are
aliases and now we can easily revert audio to IPL_VM if necessary,
without having to revert the whole branch.

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.

Refactor PNP API:
- Make suspend/resume directly a device functionality. It consists of
  three layers (class logic, device logic, bus logic), all of them being
  optional. This replaces D0/D3 transitions.
- device_is_active returns true if the device was not disabled and was
  not suspended (even partially), device_is_enabled returns true if the
  device was enabled.
- Change pnp_global_transition into pnp_system_suspend and
  pnp_system_resume. Before running any suspend/resume handlers, check
  that all currently attached devices support power management and bail
  out otherwise. The latter is not done for the shutdown/panic case.
- Make the former bus-specific generic network handlers a class handler.
- Make PNP message like volume up/down/toogle PNP events. Each device
  can register what events they are interested in and whether the handler
  should be global or not.
- Introduce device_active API for devices to mark themselve in use from
  either the system or the device. Use this to implement the idle handling
  for audio and input devices. This is intended to replace most ad-hoc
  watchdogs as well.
- Fix somes situations in which audio resume would lose mixer settings.
- Make USB host controllers better deal with suspend in the light of
  shared interrupts.
- Flush filesystem cache on suspend.
- Flush disk caches on suspend. Put ATA disks into standby on suspend as
  well.
- Adopt drivers to use the new PNP API.
- Fix a critical bug in the generic cardbus layer that made D0->D3
  break.
- Fix ral(4) to set if_stop.
- Convert cbb(4) to the new PNP API.

Extend device API by device_power_private and device_power_set_private.
The latter is a temporary mean until the pnp_register API itself is
overhault. This functions allow a generic power handler to store its
state independent of the driver.

Use this and revamp the PCI power handling. Pretty much all PCI devices
had power handlers that did the same thing, generalize this in
pci_generic_power_register/deregister and the handler. This interface
offers callbacks for the drivers to save and restore state on
transistions. After a long discussion with jmcneill@ it was considered
to be powerful enough until evidence is shown that devices can handle
D1/D2 with less code and higher speed than without the full
save/restore. The generic code is carefully written to handle device
without PCI-PM support and ensure that the correct registers are written
to when D3 loses all state.

Reimplement the generic PCI network device handling on
top of PCI generic power handling.

Introduce pci_disable_retry as used and implemented locally at least by
ath(4) and iwi(4). Use it in this drivers to restore behaviour from
before the introduction of generic PCI network handling.

Convert all PCI drivers that were using pnp_register to the new
framework. The only exception is vga(4) as it is commonly used as
console device. Add a note therein that this should be fixed later.

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

audio_hw_if change
 * make open() and close() optional
 * add int (AUMODE_PLAY or AUMODE_RECORD) and audio_params_t parameters
 to round_blocksize()

Some miscellaneous cleanup:
* Encapsulate all the ring-specific variables into a substructure.  (This will
  help with some potential code sharing.)
* Don't bother with "last buffer complete" interrupts -- we should be taking an
  interrupt anyway because we set IOC on every buffer.
* Likewise, ignore CELV; it's meaningless to us.
* Get rid of the FIFO error counters, since this doesn't actually happen any
  more.

Copyright maintenance.

More code reduction.
Also, allow any sample rate between 8000 and 48000Hz.  (This range should
probably be larger, but this is what's known to work.)

Another 180 bytes shaved.

Shave another 112 bytes by reducing some divisions to shifts.

Fix a regression -- my previous changes made the kernel slightly larger.

In the trigger routines, start *all* the blocks, not just the first one.  This
was causing some "fifo under/overrun" errors during the initial trigger.

Also fixes a ring synchronization problem introduced in the earlier changes.

This should completely fix the FIFO errors with auich.

Reorder some register writes just to be safe.

Attempt to mitigate "fifo underrun" errors in two ways:
1) Update the queue pointers any time we get a block completion interrupt,
   not just when we hit the last block.
2) Set the "back-to-back enable" bit.
In addition:
3) Make sure we ack every block we transfer; there was a bug that could cause
   the audio layer to get out of sync.

constify audio_hw_if, midi_hw_if, and radio_hw_if.

add "hw.auichN.ac97rate" sysctl MIB to specify AC'97 link rate.
It is needed because automatic calibration by auich_calibrate() is not
so precise.

- Why not ioctl?
  It is not good idea to add a new ioctl operation to MI audio for
a specific audio device.
- Why not mixerctl item?
  AC'97 linke rate is not related to audio mixing.

- remove unused code
- print diagnostic messages if the primary codec does not get ready in
auich_reset_codec().

No need to check the codec ready flag in read_codec() and write_codec().
According to the ICH datasheets, the flag is unchanged unless resetting
the codec.

The flag is useless after enabling bus mastering.  This behavior is common
to all ICH chips.  The quirk handling code is removed.

Patch from http://mail-index.netbsd.org/current-users/2003/09/04/0018.html
to fix problems with a sound card

Match the nForce3 AC-97 chip.

Add missing field initializer.

Cleanup:
* auich_calibrate() assumes that the AC97 part is in its reset state.  To
  ensure this, call audio_attach_mi() after auich_calibrate().
* Explicitly support 12000Hz and 24000Hz.  (Why is there a discrete list at
  all?)
* Fix an obvious recording bug -- we were acking the wrong interrupt.
* Ensure that we don't get an interrupt during the AC97 speed probe by clearing
  the "interrupt on completion" bit in the DMA setup.

Support for 4ch/6ch audio playback.

Add entry for Intel 82801EB AC-97 audio.  Audio sounds fine with this,
although the mixer settings are a bit odd: outputs.master doesn't do anything,
but outputs.surround does.

Fix a regression of the last commit.
ICH4 needs IGNORE_CODEC_READY_MAYBE.

Not only ICH4 but also ICH0 and ICH2 might set no ICH_PCR.

DMA, not dma nor Dma.

Add extensible malloc types, adapted from FreeBSD.  This turns
malloc types into a structure, a pointer to which is passed around,
instead of an int constant.  Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.

Use aprint_*().

Apply BUS_DMA_NOCACHE for the buffers in the case of 440MX.  The

Fixed a problem that /dev/sound can not be opened in some cases.

auich_set_rate() modified audio_params::sample_rate to actual
sample rate though auich_set_params() rejected sample rates
other than some specific rates.  For example, setting 8000Hz
with auich_set_params() modified sample_rate to 7998Hz in the
case of overclocked AC97 codec, and calling auich_set_params()
again returned with EINVAL because sample_rate was 7998Hz and
auich_set_params() rejected 7998Hz.

For now, auich_set_params() never modify audio_params::sample_rate.

auichreg.h:
Remove unnecessary ICH_PM_*.

Add some constant symbols for AC97 registers and values based on OpenBSD.
Rename some symbols to sync with OpenBSD:

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,

Change pci_intr_map to get interrupt source information from a "struct
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.
