a580b31a54 Welcome to Once-a-year Sound Mega-Commit. Enjoy numerous updates and fixes
in every sense.

General
-------

- Multichannel safe, endian safe, format safe
   * Large part of critical pcm filters such as vchan.c, feeder_rate.c,
     feeder_volume.c, feeder_fmt.c and feeder.c has been rewritten so that
     using them does not cause the pcm data to be converted to 16bit little
     endian.
   * Macrosses for accessing pcm data safely are defined within sound.h in
     the form of PCM_READ_* / PCM_WRITE_*
   * Currently, most of them are probably limited for mono/stereo handling,
     but the future addition of true multichannel will be much easier.

- Low latency operation
  * Well, this require lot more works to do not just within sound driver,
    but we're heading towards right direction. Buffer/block sizing within
    channel.c is rewritten to calculate precise allocation for various
    combination of sample/data/rate size. As a result, applying correct
    SNDCTL_DSP_POLICY value will achive expected latency behaviour simmilar
    to what commercial 4front driver do.
  * Signal handling fix. ctrl+c of "cat /dev/zero > /dev/dsp" does not
    result long delay.
  * Eliminate sound truncation if the sound data is too small.
    DIY:
      1) Download / extract
         http://people.freebsd.org/~ariff/lowlatency/shortfiles.tar.gz
      2) Do a comparison between "cat state*.au > /dev/dsp" and
         "for x in state*.au ; do cat $x > /dev/dsp ; done"
         - there should be no "perceivable" differences.
    Double close for PR kern/31445.

  CAVEAT: Low latency come with (unbearable) price especially for poorly
          written applications. Applications that trying to act smarter
	  by requesting (wrong) blocksize/blockcount will suffer the most.

- Switch minimum/maximum sampling rate limit to "1" and "2016000" (48k * 42)
  due to closer compatibility with 4front driver.
  Discussed with: marcus@ (long time ago?)

- All driver specific sysctls in the form of "hw.snd.pcm%d.*" have been
  moved to their own dev sysctl nodes, notably:
  hw.snd.pcm%d.vchans -> dev.pcm.%d.vchans
  Bump __FreeBSD_version.

Driver specific
---------------

- Ditto for sysctls.

- snd_atiixp, snd_es137x, snd_via8233, snd_hda
  * Numerous cleanups and fixes.
  * _EXPERIMENTAL_ polling mode support using simple callout_* mechanisme.
   This was intended for pure debugging and latency measurement, but proven
   good enough in few unexpected and rare cases (such as problematic shared
   IRQ with GIANT devices - USB). Polling can be enabled/disabled through
   dev.pcm.0.polling. Disabled by default.

- snd_ich
  * Fix possible overflow during speed calibration. Delay final
    initialization (pcm_setstatus) after calibration finished.
    PR: kern/100169
    Tested by: Kevin Overman <oberman@es.net>
  * Inverted EAPD for few Nec VersaPro.
    PR: kern/104715
    Submitted by: KAWATA Masahiko <kawata@mta.biglobe.ne.jp>

Thanks to various people, notably Joel Dahl, Yuriy Tsibizov, Kevin Oberman,
those at #freebsd-azalia @ freenode and others for testing.

Joel Dahl will do the manpage update.

55be51bf55 - Inverted EAPD quirk for ASUS A8Jc.
- Take the literal meaning of eapdbtl, but do the inversion during
  write.

1409858b3b - Fix support for ASUS U5F laptop. This laptop (and possibly others)
need a special inverted EAPD quirk.
- Add "eapdinv" config for future testing purposes.

8d999aa8a1 - Fix wrong id for ALC882, add ALC883 id.
- Add support for the Conexant Waikiki/CX20551-22, found
  in most Toshiba P100 series laptops. Despite of growing
  urban legend of "unsupported Conexant", this codec is fully
  supported in this driver.
  Note: Toshiba P100 has broken (acpi) BIOS, thus rendering
        its soundchip useless. Please disable ACPI, or get
        BIOS updates (if any).

  URL: http://lists.freebsd.org/pipermail/freebsd-multimedia/2006-September/004896.html

- Parser cleanups to handle possible oss/mixer collision. Found
  after parsing Conexant Waikiki nodes.

- Increase resilient against resource failure during attach/detach.

- Implement simple config through hint.pcm.<unit>.config. Supported
  options:
    gpio0 (default on Acer), gpio1, gpio2, softpcmvol,
    fixedrate (default), forcestereo (default)
  * Option prefixed with "no" (such as "nofixedrate") will do
    the opposite.
  * Options can be separated using space " " or comma ",".
  * The "no" option will take precedence over anything else.
  Example:
    hint.pcm.0.config="gpio2,nofixedrate,noforcestereo,nogpio0,softpcmvol"
    hint.pcm.0.config="softpcmvol noforcestereo"

quirk.

This driver is a product of collaborative effort made by:

  Stephane E. Potvin <sepotvin@videotron.ca>
       Andrea Bittau <a.bittau@cs.ucl.ac.uk>
       Wesley Morgan <morganw@chemikals.org>
