528013d5a8 Retire the '@' symlink. It isn't really needed and causes more
problems than it solves. SYSDIR is already defined almost always and
can be used instead. Working around the one case where it isn't is
much easier than working around the fact that @ may not exist in 18
other places.

df3394b3de Remove dependence on source tree options. Move all kernel module
options into kern.opts.mk and change all the places where we use
src.opts.mk to pull in the options. Conditionally define SYSDIR and
use SYSDIR/conf/kern.opts.mk instead of a CURDIR path. Replace all
instances of CURDIR/../../etc with STSDIR, but only in the affected
files.

As a special compatibility hack, include bsd.owm.mk at the top of
kern.opts.mk to allow the bare build of sys/modules to work on older
systems. If the defaults ever change between 9.x, 10.x and current for
these options, however, you'll wind up with the host OS' defaults
rather than the -current defaults. This hack will be removed when
we no longer need to support this build scenario.

7c6b05d280 Major snd_hda driver rewrite:
- Huge old hdac driver was split into three independent pieces: HDA
controller driver (hdac), HDA CODEC driver (hdacc) and HDA sudio function
driver (hdaa).
 - Support for multichannel recording was added. Now, as specification
defines, driver checks input associations for pins with sequence numbers
14 and 15, and if found (usually) -- works as before, mixing signals
together. If it doesn't, it configures input association as multichannel.
 - Signal tracer was improved to look for cases where several DACs/ADCs in
CODEC can work with the same audio signal. If such case found, driver
registers additional playback/record stream (channel) for the pcm device.
 - New controller streams reservation mechanism was implemented. That
allows to have more pcm devices then streams supported by the controller
(usually 4 in each direction). Now it limits only number of simultaneously
transferred audio streams, that is rarely reachable and properly reported
if happens.
 - Codec pins and GPIO signals configuration was exported via set of
writable sysctls. Another sysctl dev.hdaa.X.reconfig allows to trigger
driver reconfiguration in run-time.
 - Driver now decodes pins location and connector type names. In some cases
it allows to hint user where on the system case connectors, related to the
pcm device, are located. Number of channels supported by pcm device,
reported now (if it is not 2), should also make search easier.
 - Added workaround for digital mic on some Asus laptops/netbooks.

90da2b2859 Sound Mega-commit. Expect further cleanup until code freeze.
For a slightly thorough explaination, please refer to
	[1] http://people.freebsd.org/~ariff/SOUND_4.TXT.html .

Summary of changes includes:

1 Volume Per-Channel (vpc).  Provides private / standalone volume control
  unique per-stream pcm channel without touching master volume / pcm.
  Applications can directly use SNDCTL_DSP_[GET|SET][PLAY|REC]VOL, or for
  backwards compatibility, SOUND_MIXER_PCM through the opened dsp device
  instead of /dev/mixer.  Special "bypass" mode is enabled through
  /dev/mixer which will automatically detect if the adjustment is made
  through /dev/mixer and forward its request to this private volume
  controller.  Changes to this volume object will not interfere with
  other channels.

  Requirements:
    - SNDCTL_DSP_[GET|SET][PLAY|REC]_VOL are newer ioctls (OSSv4) which
      require specific application modifications (preferred).
    - No modifications required for using bypass mode, so applications
      like mplayer or xmms should work out of the box.

  Kernel hints:
    - hint.pcm.%d.vpc (0 = disable vpc).

  Kernel sysctls:
    - hw.snd.vpc_mixer_bypass (default: 1).  Enable or disable /dev/mixer
      bypass mode.
    - hw.snd.vpc_autoreset (default: 1).  By default, closing/opening
      /dev/dsp will reset the volume back to 0 db gain/attenuation.
      Setting this to 0 will preserve its settings across device
      closing/opening.
    - hw.snd.vpc_reset (default: 0).  Panic/reset button to reset all
      volume settings back to 0 db.
    - hw.snd.vpc_0db (default: 45).  0 db relative to linear mixer value.

2 High quality fixed-point Bandlimited SINC sampling rate converter,
  based on Julius O'Smith's Digital Audio Resampling -
  http://ccrma.stanford.edu/~jos/resample/.  It includes a filter design
  script written in awk (the clumsiest joke I've ever written)
    - 100% 32bit fixed-point, 64bit accumulator.
    - Possibly among the fastest (if not fastest) of its kind.
    - Resampling quality is tunable, either runtime or during kernel
      compilation (FEEDER_RATE_PRESETS).
    - Quality can be further customized during kernel compilation by
      defining FEEDER_RATE_PRESETS in /etc/make.conf.

  Kernel sysctls:
    - hw.snd.feeder_rate_quality.
      0 - Zero-order Hold (ZOH).  Fastest, bad quality.
      1 - Linear Interpolation (LINEAR).  Slightly slower than ZOH,
          better quality but still does not eliminate aliasing.
      2 - (and above) - Sinc Interpolation(SINC).  Best quality.  SINC
          quality always start from 2 and above.

  Rough quality comparisons:
    - http://people.freebsd.org/~ariff/z_comparison/

3 Bit-perfect mode.  Bypasses all feeder/dsp effects.  Pure sound will be
  directly fed into the hardware.

4 Parametric (compile time) Software Equalizer (Bass/Treble mixer). Can
  be customized by defining FEEDER_EQ_PRESETS in /etc/make.conf.

5 Transparent/Adaptive Virtual Channel. Now you don't have to disable
  vchans in order to make digital format pass through.  It also makes
  vchans more dynamic by choosing a better format/rate among all the
  concurrent streams, which means that dev.pcm.X.play.vchanformat/rate
  becomes sort of optional.

6 Exclusive Stream, with special open() mode O_EXCL.  This will "mute"
  other concurrent vchan streams and only allow a single channel with
  O_EXCL set to keep producing sound.

Other Changes:
    * most feeder_* stuffs are compilable in userland. Let's not
      speculate whether we should go all out for it (save that for
      FreeBSD 16.0-RELEASE).
    * kobj signature fixups, thanks to Andriy Gapon <avg@freebsd.org>
    * pull out channel mixing logic out of vchan.c and create its own
      feeder_mixer for world justice.
    * various refactoring here and there, for good or bad.
    * activation of few more OSSv4 ioctls() (see [1] above).
    * opt_snd.h for possible compile time configuration:
      (mostly for debugging purposes, don't try these at home)
        SND_DEBUG
        SND_DIAGNOSTIC
        SND_FEEDER_MULTIFORMAT
        SND_FEEDER_FULL_MULTIFORMAT
        SND_FEEDER_RATE_HP
        SND_PCM_64
        SND_OLDSTEREO

b28624fde6 Update snd_emu10kx driver with recent perforce changes (and few
other changes too).

(without any real order)

1. Use device_get_nameunit for mutex naming
2. Add timer for low-latency playback
3. Move most mixer controls from sysctls to mixer(8) controls.
   This is a largest part of this patch.
4. Add analog/digital switch (as a temporary sysctl)
5. Get back support for low-bitrate playback (with help of (2))
6. Change locking for exclusive I/O. Writing to non-PTR register
   is almost safe and does not need to be ordered with PTR operations.
7. Disable MIDI until we get it to detach properly and fix memory
   managment problems.
8. Enable multichannel playback by default. It is as stable as
   single-channel mode. Multichannel recording is still an
   experimental feature.
9. Multichannel options can be changed by loader tunables.
10. Add a way to disable card from a loader tunable.
11. Add new PCI IDs.
12. Debugger settings are loader tunables now.
14. Remove some unused variables.
15. Mark pcm sub-devices MPSAFE.
16. Partially revert (bus_setup_intr -> snd_setup_intr) since it need
    to be done independently

bba4862c64 Last major commit and updates for RELENG_7:
- Rework the entire pcm_channel structure:
  * Remove rarely used link placeholder, instead, make each pcm_channel
    as head/link of each own/each other. Unlock - Lock sequence due to
    sleep malloc has been reduced.
  * Implement "busy" queue which will contain list of busy/active
    channels. This greatly reduce locking contention for example while
    servicing interrupt for hardware with many channels or when virtual
    channels reach its 256 peak channels.

- So I heard you like v chan ... O RLY?
  Welcome to Virtual **Record** Channels (vrec, rec vchans, vchans for
  recording, Rec-Chan, you decide), the ultimate solutions for your
  nagging O_RDWR full-duplex wannabe (note: flash plugins) monopolizing
  single record channel causing EBUSY.  Vrec works exactly like Vchans
  (or, should I rename it to "Vplay" :) , except that it operates on the
  opposite direction (recording). Up to 256 vrecs (like vchans) are
  possible.

  Notes:
   * Relocate dev.pcm.%d.{vchans,vchanformat,vchanrate} to each of its
     respective node/direction:
       dev.pcm.%d.play.* for "play"   (cdev = dsp%d.vp%d)
       dev.pcm.%d.rec.*  for "record" (cdev = dsp%d.vr%d)
   * Don't expect that it will magically give you ability to split
     "recording source" (eg: 1 channel for cdrom, 1 channel for mic,
     etc). Just admit that you only have a *single* recording source /
     channel. Please bug your hardware vendor instead :)

- Bump maxautovchans from 4 to 16. For a full-fledged multimedia
  desktop/workstation with too many soundservers installed (esound,
  artsd, jackd, pulse/polypaudio, ding-dong pling plong mudkip fuh fuh,
  etc), 4 seems inadequate. There will be no memory penalty here, since
  virtual channels are allocate only by demand.

- Nuke/Rework the entire statically created cdev entries. Everything is
  clonable through snd own clone manager which designed to withstand many
  kind of abusive devfs droids such as:
      * while : ; do /bin/test -e /dev/dsp ; done
      * jot 16777216 0 | while read x ; do ls /dev/dsp0.$x ; done
      * hundreds (could be thousands) concurrent threads/process opening
	"/dev/dsp" (previously, this might result EBUSY even with just
	3 contesting threads/procs).
  o Reusable clone objects (instead of creating new one like there's no
    tomorrow) after certain expiration deadline. The clone allocator will
    decide whether to reuse, share, or creating new clone.
  o Automatic garbage collector.

- Dynamic unit magic allocator. Maximum attached soundcards can be tuned
  using tunable "hw.snd.maxunit" (Default to 512). Minimum is 16, and
  maximum is 2048.

- ..other fixes, mostly related to concurrency issues.

joel@ will do the manpage updates on sound(4).

Have fun.

f856af0466 Extend the emu10kx driver. With the words of the author:
---snip---
New features:
1.	Optional multichannel recording (32 channels on Live!, 64 channels
 	on Audigy).

 	All channels are 16bit/48000Hz/mono, format is fixed.
 	Half of them are copied from sound output, another half can be
 	used to record any data from DSP. What should be recorded is
 	hardcoded in DSP code. In this version it records dummy data, but
 	can be used to record all DSP inputs, for example..

 	Because there are no support of more-than-stereo sound streams
 	multichannell stream is presented as one 32(64)*48000 Hz 16bit mono
 	stream.

Fixes:
1.	Do not assign negative values to variables used to index emu_cards
 	array. This array was never accessed when index is negative, but
 	Alexander (netchild@) told me that Coverity does not like it.
 	After this change emu_cards[0] should never be used to identify
 	valid sound card.
2.	Fix off-by-one errors in interrupt manager. Add more checks there.
3.	Fixes to sound buffering code now allows driver to use large playback
 	buffers.
4.	Fix memory allocation bug when multichannel recording is not
 	enabled.
5.	Fix interrupt timeout when recording with low bitrate (8kHz).

Hardware:
1.	Add one more known Audigy ZS card to list. Add two cards with
 	PCI IDs betwen old known cards and new one.

Other changes:
1.	Do not use ALL CAPS in messages.

Incomplete code:
1.	Automute S/PDIF when S/PDIF signal is lost.

Tested on i386 only, gcc 3.4.6 & gcc41/gcc42 (syntax only).
---snip---

This commits enables a little bit of debugging output when the driver is
loaded as a module. I did a cross-build test for amd64.

The code has some style issues, this will be addressed later.

The multichannel recording part is some work in progress to allow playing
around with it until the generic sound code is better able to handle
multichannel streams.

This is supposed to fix
