d647935801 sbuf_new(9) now returns a struct sbuf * instead of an int. If the caller 
does not provide a struct sbuf, sbuf_new(9) will allocate one and return
a pointer to it.

0978669829 "Fix" the previous initial attempt at fixing TUNABLE_INT(). This time 
around, use a common function for looking up and extracting the tunables
from the kernel environment.  This saves duplicating the same function
over and over again.  This way typically has an overhead of 8 bytes + the
path string, versus about 26 bytes + the path string.

81930014ef Make the TUNABLE_*() macros look and behave more consistantly like the 
SYSCTL_*() macros.  TUNABLE_INT_DECL() was an odd name because it didn't
actually declare the int, which is what the name suggests it would do.

b794010414 Move out the files from src/sys/isa/ic/ to src/sys/dev/ic/, so they 
can be made userland-visible as <dev/ic/...>.  Also, those files are
not supposed to contain any bus-specific details at all, so placing
them under .../isa/ has been a misnomer from the beginning.

The files in src/sys/dev/ic/ have been repo-copied from their old
location (this commit is a forced null commit there to record this
message).

285648f9d2 beginnings of virtual playback channel support 
instead of using two malloced arrays for storing channel lists, use an
slist.  convert the sndstat device to use sbufs and optionally provide more
detail about channel state.

vchans are software mixed playback channels.  they are not enabled by this
commit.  they use the feeder infrastructure to emulate normal playback
channels in a manner transparent to applications, whilst providing as many
channels are desired, especially suitable for devices with only one hardware
playback channel.  in the future they will provide additional features.

those wishing to test this functionality will need to add vchan.c to
sys/conf/files and use 'sysctl -w hw.snd.pcm0.vchans' to enable it.

blocksize and auto-rate selection are not yet supported.

66ef8af5b0 mega-commit. 
this introduces a new buffering mechanism which results in dramatic
simplification of the channel manager.

as several structures have changed, we take the opportunity to move their
definitions into the source files where they are used, make them private and
de-typedef them.

the sound drivers are updated to use snd_setup_intr instead of
bus_setup_intr, and to comply with the de-typedefed structures.

the ac97, mixer and channel layers have been updated with finegrained
locking, as have some drivers- not all though.  the rest will follow soon.

  their own devices these sysctl's will move to live under a mixerX tree.

  with the name instead of the number.

6d97297a6a The 'maxchans' count is one more than the number of channels, so 
'chancount' never got up to equaling 'maxchans'.  As a result,
pcm_makelinks() was never called, and one always had to set the sysctl to
get the /dev/mixer and other symlinks generated in the DEVFS case.  Instead,
change the test in pcm_addchan() to call pcm_makelinks() after the first
channel is initialized, since the aliases are linked to channel 0.

1b40801722 - When acknowledging interrupts, write the value 0xff to the interrupt 
status register rather than 0.  Without this, a single hardware volume
  event triggers an interrupt storm.
- Implement hardware volume control for the Maestro chips.  This version
  only handles the case where both channels are adjusted at the same time.

d0d4e34743 Add a new API for soundcards that have hardware volume control: 
- The mixer_hwmute() function can be called when a soundcard receives a
  mute request.
- The mixer_hwstep() function can be used to adjust the volume of one or
  both channels.
- The 'hw.snd.hwvol_step' sysctl determines the amount that mixer_hwstep()
  adjusts the volume by on each call.
- The 'hw.snd.hwvol_mixer' sysctl specifies the mixer device to adjust the
  volume on for both functions.  The values used correspond to the
  SOUNDCARD_MIXER_* constants.

db90128160 Avoid the modules madness I inadvertently introduced by making the 
cloning infrastructure standard in kern_conf.  Modules are now
the same with or without devfs support.

If you need to detect if devfs is present, in modules or elsewhere,
check the integer variable "devfs_present".

This happily removes an ugly hack from kern/vfs_conf.c.

This forces a rename of the eventhandler and the standard clone
helper function.

Include <sys/eventhandler.h> in <sys/conf.h>: it's a helper #include
like <sys/queue.h>

Remove all #includes of opt_devfs.h they no longer matter.

0edeb3dc90 A couple of cosmetic fixes, plus a biggie: When checking the DMA 
position, channel 1's dma position register must be quiescent. So
the driver will spl, pause the DMA, delay a bit and hold as still as
possible while snapping the picture.

I'm sure there HAS to be a better way to do this, but if there is, it's
not documented.

So far as I can tell, this fixes recording, which means the Solo is open

3e0f102e57 With this evil hack the DS1 driver works on our Intel desktop 
motherboards that use YMF740's.  It has a strange subvendor and subdevice
ID and requires a disturbingly long delay after the ac97 codec init.
Cameron hasn't had this driver tested on another 740 yet, so we don't know
if this is a quirk of all 740's, or if its just something about the codec
that Intel used.

<sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall
not be made a nested include according to bdes teachings on the
subject of nested includes.

Diskdrivers and similar stuff below specfs::strategy() should no
longer need to include <sys/buf.> unless they need caching of data.
