- convert the audio softintr's to SOFTINT_SERIAL.  right now they're on
  the same priority level as USB and if an audio softintr is blocked
  waiting for a usb event, they'll dead lock.  also, audio being higher
  priority is a fine idea.

- revert the previous audio.c changes as they were unsafe and this change
  obviates the need for them.

XXX:  convert the audio softint's to use a high priority thread or a
XXX:  workqueue would be better again.

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.

A pointer typedef entails trading too much flexibility to declare const
and non-const types, and the kernel uses both const and non-const
PMF qualifiers and device suspensors, so change the pmf_qual_t and
device_suspensor_t typedefs from "pointers to const" to non-pointer,
non-const types.

OSS audio allows mixer operations on the dsp device. NetBSD would return
EINVAL in these circumstances. This can break audio in apps running under
Linux emulation (e.g. Citrix ICA client will mute all audio when volume
control used). Therefore, pass unrecognised ioctls attempted on dsp devices
to mixer_ioctl.

In pmf(9), improve the implementation of device self-suspension
and make suspension by self, by drvctl(8), and by ACPI system sleep
play nice together.  Start solidifying some temporary API changes.

1. Extract a new header file, <sys/device_if.h>, from <sys/device.h> and
   #include it from <sys/pmf.h> instead of <sys/device.h> to break the
   circular dependency between <sys/device.h> and <sys/pmf.h>.

2. Introduce pmf_qual_t, an aggregate of qualifications on a PMF
   suspend/resume call.  Start to replace instances of PMF_FN_PROTO,
   PMF_FN_ARGS, et cetera, with a pmf_qual_t.

3. Introduce the notion of a "suspensor," an entity that holds a
   device in suspension.  More than one suspensor may hold a device
   at once.  A device stays suspended as long as at least one
   suspensor holds it.  A device resumes when the last suspensor
   releases it.

   Currently, the kernel defines three suspensors,

   3a the system-suspensor: for system suspension, initiated
      by 'sysctl -w machdep.sleep_state=3', by lid closure, by
      power-button press, et cetera,

   3b the drvctl-suspensor: for device suspension by /dev/drvctl
      ioctl, e.g., drvctl -S sip0.

   3c the system self-suspensor: for device drivers that suspend
      themselves and their children.  Several drivers for network
      interfaces put the network device to sleep while it is not
      administratively up, that is, after the kernel calls if_stop(,
      1).  The self-suspensor should not be used directly.  See
      the description of suspensor delegates, below.

   A suspensor can have one or more "delegates".  A suspensor can
   release devices that its delegates hold suspended.  Right now,
   only the system self-suspensor has delegates.  For each device
   that a self-suspending driver attaches, it creates the device's
   self-suspensor, a delegate of the system self-suspensor.

   Suspensors stop a system-wide suspend/resume cycle from waking
   devices that the operator put to sleep with drvctl before the cycle.
   They also help self-suspension to work more simply, safely, and in
   accord with expectations.

4. Add the notion of device activation level, devact_level_t,
   and a routine for checking the current activation level,
   device_activation().  Current activation levels are DEVACT_LEVEL_BUS,
   DEVACT_LEVEL_DRIVER, and DEVACT_LEVEL_CLASS, which respectively
   indicate that the device's bus is active, that the bus and device are
   active, and that the bus, device, and the functions of the device's
   class (network, audio) are active.

   Suspend/resume calls can be qualified with a devact_level_t.
   The power-management framework treats a devact_level_t that
   qualifies a device suspension as the device's current activation
   level; it only runs hooks to reduce the activation level from
   the presumed current level to the fully suspended state.  The
   framework treats a devact_level_t qualifying device resumption
   as the target activation level; it only runs hooks to raise the
   activation level to the target.

5. Use pmf_qual_t, devact_level_t, and self-suspensors in several
   drivers.

6. Temporarily add an unused power-management workqueue that I will
   remove or replace, soon.

Network protocol interrupts can now block on locks, so merge the globals
proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock).
Implications:

- Inspecting process state requires thread context, so signals can no longer
  be sent from a hardware interrupt handler. Signal activity must be
  deferred to a soft interrupt or kthread.

- As the proc state locking is simplified, it's now safe to take exit()
  and wait() out from under kernel_lock.

- The system spends less time at IPL_SCHED, and there is less lock activity.

Use device_t and its accessors throughout.  Use aprint_*_dev().

Improve PMF-ability.

        Add a 'flags' argument to suspend/resume handlers and
        callers such as pmf_system_suspend().

        Define a flag, PMF_F_SELF, which indicates to PMF that a
        device is suspending/resuming itself.  Add helper routines,
        pmf_device_suspend_self(dev) and pmf_device_resume_self(dev),
        that call pmf_device_suspend(dev, PMF_F_SELF) and
        pmf_device_resume(dev, PMF_F_SELF), respectively.  Use
        PMF_F_SELF to suspend/resume self in ath(4), audio(4),
        rtw(4), and sip(4).

        In ath(4) and in rtw(4), replace the icky sc_enable/sc_disable
        callbacks, provided by the bus front-end, with
        self-suspension/resumption.  Also, clean up the bus
        front-ends.  Make sure that the interrupt handler is
        disestablished during suspension.  Get rid of driver-private
        flags (e.g., RTW_F_ENABLED, ath_softc->sc_invalid); use
        device_is_active()/device_has_power() calls, instead.

        In the network-class suspend handler, call if_stop(, 0)
        instead of if_stop(, 1), because the latter is superfluous
        (bus- and driver-suspension hooks will 'disable' the NIC),
        and it may cause recursion.

        In the network-class resume handler, prevent infinite
        recursion through if_init() by getting out early if we are
        self-suspending (PMF_F_SELF).

rtw(4) improvements:

        Destroy rtw(4) callouts when we detach it.  Make rtw at
        pci detachable.  Print some more information with the "rx
        frame too long" warning.

Remove activate() methods:

        Get rid of rtw_activate() and ath_activate().  The device
        activate() methods are not good for much these days.

Make ath at cardbus resume with crypto functions intact:

        Introduce a boolean device property, "pmf-powerdown".  If
        pmf-powerdown is present and false, it indicates that a
        bus back-end should not remove power from a device.

        Honor this property in cardbus_child_suspend().

        Set this property to 'false' in ath_attach(), since removing
        power from an ath at cardbus seems to lobotomize the WPA
        crypto engine.  XXX Should the pmf-powerdown property
        propagate toward the root of the device tree?

Miscellaneous ath(4) changes:

        Warn if ath(4) tries to write crypto keys to suspended
        hardware.

        Reduce differences between FreeBSD and NetBSD in ath(4)
        multicast filter setup.

        Make ath_printrxbuf() print an rx descriptor's status &
        key index, to help debug crypto errors.

        Shorten a staircase in ath_ioctl().  Don't check for
        ieee80211_ioctl() return code ERESTART, it never happens.

au_setup_ports - don't hide ports->nports++ inside another expression,

Add a new ioctl AUDIO_GETBUFINFO. It works like AUDIO_GETINFO, but
doesn't obtain the ports, gain and balance related parameters.
Those generally require reading from the hardware and therefore are much
more expensive to obtain. Modify OSS emulation to use the new ioctl
where possible.

This reduces CPU usage of mplayer during mp3 playback with my Thinkpad
from 20% to < 1% and from 50% to 20% during Xvid playback.

merge kent-audio1 branch, which introduces audio filter pipeline to the MI
audio framework


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

Fix a couple of long-standing bugs in the volume control(s) part of the
audio device interface:

1) When attempting to match the appropriate mixer control, we weren't
checking the class label, but only the second level label, so for
devices that had both an "inputs.cd" and a "record.cd", for example,
we could never do the right thing except by chance. For this reason,
evidently, all the record masters were labeled (by the underlying
drivers) either "record.record" or "record.volume", to distinguish
from "outputs.master". We'll now accept "record.master", and document
that as the the new preferred way.

2) More importantly, the model was deficient. Selecting a port on many
chips completely disables most of the level controls, which doesn't play
nice with other applications which are trying to use the interface. Now,
selecting a port simply sets which mixer input control shall be changed,
setting state in the audio layer. In other words, the "mixerout" port
is really selected all the time, enabling the final stage mixer, and
setting "gain" sets the level of the appropriate input. It should be
possible for separate applications to each control the mic, dac, and cd
inputs at the same time using this interface, simply by reiterating their
port selections with each change, but applications that don't bother to
do that aren't any worse off than they were before.

The user is expected to set the master output with another application,
dedicated to that task. Though it is now meaningful to select "no port"
with the audio device interface, to manipulate the master output, there's
no particular reason for an audio device consumer to do that. (I added
the capability in order to restore the initial state of the audio device,
for testing purposes. It might also be useful to users of broken binary-
only applications.)

Observe that the mixer device interface (and so, "mixerctl") still
retains all capabilities, including the ability to set the actual input
port on the chip, overriding the level controls. No change is being made
to the mixer device interface. The mixer device simply presents all the
controls on the chip, with no attempt at abstraction, so there are no
bugs there.

The upshot is, that applications that have been trying to use the audio
device interface to change the volume, such as mplayer, now "just work".

I've tested these changes extensively with "eso" and "eap" since first

A bit of cleanup:
* Separate the code to set the default parameters into a new function,
  audio_set_defaults().  Make it use audiosetinfo(), which properly initializes
  the block size and whatnot.  Use this in both audioattach() and the
  /dev/audio case of audio_open().
* Do not force a reinitialization when /dev/sound is opened.
* Do all of the block size sanity checks in auto_init_ringbuffer(), not in
  both audio_calc_blksize() and audiosetinfo().
* Fix a bug in audiosetinfo() that caused the block size to not be recalculated
  immediately if we set it to 0.
* For AUDIO_GET[IO]OFFS, modify the deltablks calculation so that it gives us
  the number of block boundaries crossed.

If the user is providing a mode value in AUDIO_SETINFO, that value
cannot change the recording or playback mode of the device, it can
only change other mode-like values (like AUMODE_PLAY_ALL).  Be very
explicit about fixing up the user's mode value based on the mode of
the device.  Before, giving AUMODE_PLAY_ALL could cause AUMODE_PLAY
to become set on the device, and once AUMODE_PLAY_ALL was set it
was impossible to clear.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

Changes to the sudio system:
  - It is now possible to handle devices that want "looping" DMA,
    e.g. the SoundBlaster correctly.  The WSS and SB drivers use this.
    To do this several new methods were introduced in audio_hw_if.
  - Different silence handling (forced by previous change).
  - The audio driver can now be mmap()-ed, but due to problems in
    the VM system only for writing for now.
  - The OSS (Linux) audio emulation takes advantage of some of the
    new features.
