ab85003bf5 Fixed breakage from removing the used include of <sys/buf.h> in the
previous commit:
Include <sys/mutex.h> and its prerequisite <sys/lock.h> instead of
depending on namespace pollution in <sys/buf.h>.  Only do this in the
__FreeBSD_version > 500000 case although the __FreeBSD_version < 500000
case has already rotted.

47d5a0f3e5 Marginally simplify dsp_open error handling by adding an early test to
determine liklihood of opening device in requested directions.  Makes for
simpler error handling and change should close kern/35004.

108082c42e s/AC97_MIX_PHONES/AC97_MIX_AUXOUT/ to match ac97r2.{2,3}.
Attempt to determine what function of AUX_OUT is: "True line level
out", "Headphone out", or "4-Channel out" and frig OSS mixer label
accordingly.

Addresses problem raised by Randy Bush on -multimedia of not being
able to hear audio on ich2 m/b which was eventually found to be
because the mixer monitor value was 0.  On this h/w the label
"monitor" should now be presented as the marginally more intuitive
"ogain".

opening the device, eg one read only and one write only, and the

has been specified through /boot/loader.conf as opposed to setting it

of virtual channel. Do not initialize a new vchan for a given physical
channel if other physical channel already has one created.

85f190e4d1 Fixes to make select/poll mpsafe.
Problem:
  selwakeup required calling pfind which would cause lock order
  reversals with the allproc_lock and the per-process filedesc lock.
Solution:
  Instead of recording the pid of the select()'ing process into the
  selinfo structure, actually record a pointer to the thread.  To
  avoid dereferencing a bad address all the selinfo structures that
  are in use by a thread are kept in a list hung off the thread
  (protected by sellock).  When a selwakeup occurs the selinfo is
  removed from that threads list, it is also removed on the way out
  of select or poll where the thread will traverse its list removing
  all the selinfos from its own list.

Problem:
  Previously the PROC_LOCK was used to provide the mutual exclusion
  needed to ensure proper locking, this couldn't work because there
  was a single condvar used for select and poll and condvars can
  only be used with a single mutex.
Solution:
  Introduce a global mutex 'sellock' which is used to provide mutual
  exclusion when recording events to wait on as well as performing
  notification when an event occurs.

Interesting note:
  schedlock is required to manipulate the per-thread TDF_SELECT
  flag, however if given its own field it would not need schedlock,
  also because TDF_SELECT is only manipulated under sellock one
  doesn't actually use schedlock for syncronization, only to protect
  against corruption.

Proc locks are no longer used in select/poll.

a0eed7bc1c Add a sysctl, sysctl hw.snd.report_soft_formats, that controls whether the
AIOGCAP ioctl reports software-emulated formats.  It defaults to on.  People
who use performance-sensitive audio software and do not want it to pick a
software-emulated audio format instead of one supported by their hardware
should turn it off.

This unbreaks isdnphone(1) on systems with PCM-only sound cards.

79e6a82b48 make the feederchain builder work for recording. this has not been tested
extensively as none of my testboxes have speakers or an audio source at
present, but the chains built look correct and reading /dev/audio (ulaw,
translated from signed 16 bit little-endian) gives values within the
expected range for silence.

095159ecd1 add more error checking to open of /dev/dsp* and /dev/audio* - if the

note that this should never happen once the feederchain builder works for
recording.

make the kernel aware that there are smaller units of scheduling than the

This is functionally equivalent to teh previousl -current except
