 1.73  27-Dec-2019  msaitoh s/suport/support/
 1.72  08-May-2019  isaki Merge isaki-audio2 branch, the overhaul of audio subsystem.
- Interrupt-oriented system rather than thread-oriented.
- Improve stability, quality and performance.
- Split playback and record cleanly. Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism. The encoding/channels/frequency
conversions are completely handled in the upper layer. So the hard-
ware driver only converts its hardware encoding (if necessary).
- audio_hw_if changes:
- Obsoletes query_encoding and add query_format instead.
- Obsoletes set_params and add set_format instead.
- Remove drain, setfd, mappage.
- The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.
- ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced.
- cleanup config attributes: au*conv and mulaw.
- All hardware drivers should follow it (I've done as much as possible).

Some file paths are changed:
- dev/audio.c -> dev/audio/audio.c (rewritten)
- dev/audiovar.h -> dev/audio/audiovar.h
- dev/audio_dai.h -> dev/audio/audio_dai.h
- dev/audio_if.h -> dev/audio/audio_if.h
- dev/audiobell.c -> dev/audio/audiobell.c
- dev/audiobellvar.h -> dev/audio/audiobellvar.h
- dev/mulaw.[ch] -> dev/audio/mulaw.[ch] + dev/audio/alaw.c
 1.71  16-Mar-2019  isaki branches: 1.71.2;
Use C99 style struct initializer to audio_hw_if.
 1.70  24-Nov-2011  mrg branches: 1.70.50;
put back IPL_AUDIO and splaudio(), at the request of rmind. they are
aliases and now we can easily revert audio to IPL_VM if necessary,
without having to revert the whole branch.
 1.69  23-Nov-2011  jmcneill 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.

Welcome to 5.99.57.
 1.68  24-Mar-2010  dyoung branches: 1.68.8; 1.68.10;
Do not use unitialized bus_space_tag_t's. Use the tag(s) from the
attachment arguments.
 1.67  15-Mar-2008  cube branches: 1.67.4; 1.67.16; 1.67.24; 1.67.26;
Split device_t and softc for sb(4) and all its attachments.
 1.66  19-Oct-2007  ad branches: 1.66.12; 1.66.16;
machine/{bus,cpu,intr}.h -> sys/{bus,cpu,intr}.h
 1.65  16-Nov-2006  christos branches: 1.65.6; 1.65.8; 1.65.22; 1.65.24; 1.65.28;
__unused removal on arguments; approved by core.
 1.64  12-Oct-2006  christos - sprinkle __unused on function decls.
- fix a couple of unused bugs
- no more -Wno-unused for i386
 1.63  03-Sep-2006  christos branches: 1.63.2; 1.63.4;
add missing initializers
 1.62  11-Dec-2005  christos branches: 1.62.4; 1.62.8;
merge ktrace-lwp.
 1.61  14-Jan-2005  kent branches: 1.61.10;
ansify and KNF
 1.60  29-Oct-2004  yamt constify audio_hw_if, midi_hw_if, and radio_hw_if.
 1.59  14-Sep-2004  drochner Separate the namespace for default (ie unspecified) locators used
by the isa.c bus driver and the "address/whatever not specified"
argument passed to leaf device drivers.
The former is "ISACF_XXX_DEFAULT" as generaterd by config(8), the latter
"ISA_UNKNOWN_XXX", defined in isavar.h.
This way we save a dependency of every ISA device driver on "locators.h".
 1.58  22-Apr-2004  itojun sprintf -> snprintf
 1.57  03-May-2003  wiz branches: 1.57.2;
DMA, not dma nor Dma.
 1.56  02-Oct-2002  thorpej Fix sizeof and whitespace bug from the script I'm using to do the
CFATTACH_DECL conversion. (Grumble.)
 1.55  02-Oct-2002  thorpej Use CFATTACH_DECL().
 1.54  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.53  11-Jan-2002  jdolecek Resurrect the 'sc->sc_sbdsp.sc_dev.dv_cfdata = match' in pasprobe(),
it's needed for sbdsp.c:sbdsp_probe().
 1.52  07-Jan-2002  thorpej Overhaul of the ISA autoconfiguration code to support direct
configuration of devices logically attached to the ISA bus:

* Change the isa_attach_args to have arrays of io, mem, irq, drq
resources.
* Add a "pnpnames" and a linked list of "pnpcompatnames" to the
isa_attach_args. If either of these members are non-NULL,
direct configuration of the bus is being performed. Add an
ISA_DIRECT_CONFIG() macro to test for this.
* Drivers are not allowed to modify the isa_attach_args unless
direct configuration is not being performed and the probe fucntion
is returning success.
* Adapt device drivers -- currently, all driver probe routines return
"no match" if ISA_DIRECT_CONFIG() evaluates to true.
 1.51  13-Nov-2001  lukem add RCSID
 1.50  03-Oct-2001  augustss Add a new optional method, dev_ioctl, to the audio hardware driver interface.
It is called when an unrecognized ioctl() is performed on a device,
thus allowing ioctl()s that frob the hardware driver (like loading
microcode).
 1.49  18-Jul-2001  thorpej branches: 1.49.2;
bzero -> memset
 1.48  15-May-2001  lukem branches: 1.48.2;
delint: () protect some macro args
 1.47  28-Apr-2000  jdolecek branches: 1.47.6;
pasfind(): avoid silly bug - if bus_space_map() of SB I/O space failed,
we used bad label and tried to bus_space_unmap() invalid memory
region

Fixes port-i386/9992 by Jarkko Teppo <jate@uwasa.fi>.
 1.46  18-Feb-1999  mycroft branches: 1.46.2; 1.46.8;
Add separate halt_output and halt_input routines.
 1.45  17-Feb-1999  mycroft Pass the direction to the allocm and round_buffersize methods.
Some drivers need this to properly allocate DMAable memory.
 1.44  17-Aug-1998  augustss * Redo the way the way the MIDI driver attaches to audio devices.
* Improve the midisyn layer a little.
* Add a driver for the Yamaha OPL[23] FM synths.
The opl driver is not finished yet; it sounds pretty awful.

For some strange reason I cannot get any FM sound from my SB64 cards,
but a regular SB16 works fine.
 1.43  10-Aug-1998  mycroft Use the new trigger_{in,out}put interface.
Also, even on the SB1, we can leave the DMA controller in auto-initalize
mode and just send a command to the board for each block. This may help
prevent FIFO underruns.
 1.42  22-Jun-1998  augustss Make PAS driver work again. From "John F. Woods" <jfw@jfwhome.funhouse.com>.
 1.41  09-Jun-1998  thorpej Nuke __BROKEN_INDIRECT_CONFIG.
 1.40  09-Jun-1998  thorpej Adjust for changes to the ISA DMA API.
 1.39  23-Mar-1998  augustss Update for __BROKEN_INDIRECT_CONFIG. Still untested since it is so hard
to find testers for these old cards.
 1.38  22-Mar-1998  drochner Make this file compile without BROKRN_INDIRECT_CONFIG.
(Brute force - device probe always returns 0. Should be fixed soon.)
 1.37  12-Jan-1998  thorpej Update for config changes.
 1.36  19-Oct-1997  augustss Make the audio API (almost) SunOS compatible.
The changes is to allow some limited mixer manipulation through
the audio device (instead of the mixer device).
This rendered 4 methods in audio_hw_if unused so garbage collect these.
 1.35  14-Sep-1997  augustss Get rid of `register'.
 1.34  19-Aug-1997  augustss Change the MI audio driver so it attaches to the MD driver in the
normal way. This requires adding a line to the config files to
get audio to work again.
 1.33  31-Jul-1997  augustss Audio changes:
- Change the way attach and open works to allow multiple audio
devices.
- Split the mulaw.c file into two to avoid dragging in mulaw
convertsion when they are not needed. Add 16 bit alaw/mulaw tables.
- Change the way audio properties are gotten.
- Recognize more versions os SoundBlaster.
 1.32  28-Jul-1997  augustss branches: 1.32.2;
Audio: Remove the machine dependant code I put in audio.c by mistake.
This adds another method to audio_hw_if. Also remove a field from
audio_hw_if that was not read-only.
 1.31  28-Jul-1997  augustss audio: Minor cleanup and enable looping DMA for PSS and PAS.
 1.30  27-Jul-1997  augustss audio: Simplify handling of AUDIO_SETFD and committing of encoding mode.
 1.29  27-Jul-1997  augustss 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.
 1.28  25-Jul-1997  augustss Make PAS audio work again.
From John F. Woods, PR #3859.
 1.27  06-Jun-1997  thorpej Pull thorpej-bus-dma branch into mainline.
 1.26  09-May-1997  augustss branches: 1.26.2;
Change the interface between high and lowlevel audio drivers again:
Set the encoding parameters slightly differently.
Remove the SW encoding/decodinf functions from this interface
and move them to the audio_parameter struct; this is both more efficient
and flexible.
 1.25  29-Apr-1997  augustss Change the interface between the high and low level audio drivers
so that all audio encoding parameters are set at once. This simplifies
the interface and make error checking easier.
 1.24  06-Apr-1997  augustss Make sure the bus tag is set where we need it.
 1.23  24-Mar-1997  jtk use new name sc_drq8 and initialize sc_drq16 (reflect changes to SB driver)
 1.22  20-Mar-1997  mycroft Combine set_encoding and set_precision into a single set_format interface.
 1.21  13-Mar-1997  mycroft Don't share the silence block between devices. Make silence filling work for
more encodings, and make it device-independent. From Lennart Augustsson, in
PR kern/3305.
 1.20  12-Nov-1996  mikel Use device struct from sbdsp_softc, eliminate redundant softc members.
Fixes PR kern/2237.
 1.19  13-Oct-1996  christos backout kprintf changes
 1.18  10-Oct-1996  christos printf -> kprintf, sprintf -> ksprintf
 1.17  12-May-1996  mycroft Use intr.h.
 1.16  29-Apr-1996  christos - prototype fixes
 1.15  11-Apr-1996  cgd update for addition of a machine-dependent cookie as the first argument
to isa_intr_{,dis}establish().
 1.14  17-Mar-1996  thorpej New device attachment scheme:

- split softc size and match/attach out from cfdriver into
a new struct cfattach.

- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
 1.13  01-Mar-1996  mycroft Add support to the ISA DMA framework for auto-initialize mode.
Add experimental SB16 code, disabled for now.
 1.12  16-Feb-1996  mycroft Prototype the probe and attach functions.
 1.11  24-Dec-1995  mycroft The IST_* and IPL_* constants are not bus-specific; don't treat them as such.
Change splimp -> splnet in Ethernet, ARCnet, and FDDI drivers.
 1.10  10-Nov-1995  mycroft Convert IRQ, DRQ, and port numbers to int.
 1.9  19-Jul-1995  brezak GUS audio driver from John Kohl.
 1.8  07-Jul-1995  brezak Cleanup
 1.7  08-May-1995  brezak Remove strings
 1.6  17-Apr-1995  cgd update for new locations
 1.5  17-Apr-1995  cgd clean up several ISA device interfaces: autoconfiguration, header
inclusion, and interrupt configuration. more work still needs to be done,
but it's getting better...
 1.4  25-Mar-1995  mycroft Use void* rather than caddr_t in many places.
 1.3  14-Mar-1995  brezak Fixes defect port-i386/864 from John Woods (jfw@jfwhome.funhouse.com) with
supplied patch. pas.c doesn't recognize ProAudio Spectrum 16 Basic card.
 1.2  28-Feb-1995  brezak Use irq directly not as a mask
 1.1  21-Feb-1995  brezak PAS driver; uses SB emulation for now
 1.26.2.1  13-May-1997  thorpej Adapt to new software interface to the on-board ISA DMA controller.
 1.32.2.2  16-Sep-1997  thorpej Update marc-pcmcia branch from trunk.
 1.32.2.1  23-Aug-1997  thorpej Update marc-pcmcia branch from trunk.
 1.46.8.1  20-Nov-2000  bouyer Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
 1.46.2.1  30-Apr-2000  he Pull up revision 1.47 (requested by jdolecek):
