 1.62  08-Jan-2024  chs mpu / opl: add an interface attribute to config_found() calls for these

specify an interface attribute when attaching mpu and opl devices.
the PCI devices that are the parents of these midi devices
(cmpci, eso, fms, sv, yds) have two interface attributes:
"audiobus", and also one named the same as the parent device,
eg. "cmpci" has an interface attribute named "cmpci".
we must specify the latter one to attach these children.

Merge thorpej-cfargs2.
 1.60  24-Apr-2021  thorpej branches: 1.60.8;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).
 1.59  06-Feb-2021  isaki branches: 1.59.2;
Add a missing mutex_spin_exit().
 1.58  19-Apr-2020  isaki branches: 1.58.2;
Fix round_blocksize not to return 0.
 1.57  28-Oct-2019  joerg branches: 1.57.6;
Fix operand priority of bit op vs ternary operator.
 1.56  08-Jun-2019  isaki branches: 1.56.2;
Clean get_props().
- Make get_props() return AUDIO_PROP_{PLAYBACK,CAPTURE} properly.
This eliminates need for audio.c to take care of such (old)
drivers which don't return both of PLAYBACK and CAPTURE.
- All get_props() doesn't need to return AUDIO_PROP_MMAP.
It is handled in the audio layer now.
 1.55  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
 1.54  16-Mar-2019  isaki branches: 1.54.2;
Use C99 style struct initializer to audio_hw_if.
 1.53  09-Dec-2018  jdolecek use pci_intr_establish_xname() everywhere
 1.52  01-Jun-2017  chs branches: 1.52.8; 1.52.10;
remove checks for failure after memory allocation calls that cannot fail:

kmem_alloc() with KM_SLEEP
kmem_zalloc() with KM_SLEEP
percpu_alloc()
pserialize_create()
psref_class_create()

all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.
 1.51  14-Jul-2016  msaitoh - Use aprint*() more in xxx_attach().
- Add missing aprint_naive("\n").
- Remove extra spaces and tabs.
- KNF.
 1.50  29-Mar-2014  christos branches: 1.50.6;
make pci_intr_string and eisa_intr_string take a buffer and a length
instead of relying in local static storage.
 1.49  18-Mar-2014  riastradh Merge riastradh-drm2 to HEAD.
 1.48  17-Jul-2013  soren A few "isa" files are so tightly integrated into the x86 platform code
as to not really be part of the optional isa bus autoconf machinery.

Allows configuring a kernel like so:

include "arch/amd64/conf/GENERIC"
no isa
 1.47  27-Oct-2012  chs branches: 1.47.2; 1.47.8;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.46  24-Nov-2011  mrg branches: 1.46.8;
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.
 1.45  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.

 1.26  10-Jan-2005  kent 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
 1.25  29-Oct-2004  yamt branches: 1.25.2;
constify audio_hw_if, midi_hw_if, and radio_hw_if.
 1.24  09-Jul-2004  mycroft Clean up. Attempt to make these safer against stray interrupts.
 1.23  09-Jul-2004  mycroft There's no need to halt the input and output pipes in the close routine --
audio_close() takes care of this.
 1.22  03-May-2003  wiz branches: 1.22.2;
DMA, not dma nor Dma.
 1.21  22-Feb-2003  tsutsui {HZ,hz,hZ} -> Hz
 1.20  20-Feb-2003  hannken The SonicVibes DMA is broken and only works on 24-bit addresses. As long
as bus_dmamem_alloc_range() is missing we use the ISA dma tag on i386.

The iorange for the dma registers now gets allocated near the used range.
Chances are high, that this range is valid on this PCI bus.

This one is really ugly :-)

Approved by: Lennart Augustsson <augustss@netbsd.org>
 1.19  01-Feb-2003  thorpej Add extensible malloc types, adapted from FreeBSD. This turns
malloc types into a structure, a pointer to which is passed around,
instead of an int constant. Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.
 1.18  02-Oct-2002  thorpej Add trailing ; to CFATTACH_DECL.
 1.17  30-Sep-2002  thorpej Use CFATTACH_DECL().
 1.16  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.15  13-Nov-2001  lukem add RCSID
 1.14  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).
 1.13  19-Jul-2001  kleink branches: 1.13.2;
Hint BUS_DMA_READ and BUS_DMA_WRITE.
 1.12  28-Dec-2000  sommerfeld branches: 1.12.2; 1.12.4;
Change pci_intr_map to get interrupt source information from a "struct
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

Tested on alpha and i386; welcome to 1.5Q
 1.11  26-Jun-2000  simonb Change the kernel mmap interface so that the offset to map is an
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".

Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
 1.10  01-Nov-1999  augustss branches: 1.10.6;
Make little endian and big endian version of all functions
that deal with 16 bit samples. Let the drivers decide which ones
to use.
 1.9  10-Jul-1999  kleink branches: 1.9.2; 1.9.4; 1.9.6;
Fix a buglet in the driver's DMA buffer list ipmlementation, causing the next-
in-list (wrong) descriptor structure of the buffer in question to be freed.
 1.8  14-Apr-1999  jonathan initialize 'p' for lame gcc-2.7.2.2 flow analysis.
 1.7  22-Mar-1999  mycroft branches: 1.7.2;
Make 48KHz output work.
 1.6  19-Feb-1999  mycroft This is an utterly revolting hack to work around the previously mentioned
lossage. On the Alpha, we force the buffers to be allocated through the SGMAP
so that the PCI bus addresses are low enough.
At least it's only one line of code...
 1.5  18-Feb-1999  mycroft Pass the correct address (PCI bus address, not PA) to the card.
Also fix some typos and add more debugging printf()s.
This would work on the Alpha, but the card I have appears to have the upper
address bits chopped off, and the ring buffer gets mapped using the DGMAP,
which uses the upper bits. Boom.
 1.4  18-Feb-1999  mycroft spaces -> tabs
 1.3  18-Feb-1999  mycroft A few things:
* Use the trigger interface.
* Permit different encodings for record and playback.
* Set AUDIO_PROP_INDEPENDENT.
* Fix the mmap(2) hole again.
* Use 16-bit mode for a-law and u-law playback.
 1.2  17-Feb-1999  mycroft Pass the direction to the allocm and round_buffersize methods.
Some drivers need this to properly allocate DMAable memory.
 1.1  10-Dec-1998  augustss Add a driver for the S3 SonicVibes chip. From OpenBSD and
Constantine Paul Sapuntzakis (csapuntz@cvs.openbsd.org) with

XXX The driver still needs work.

 1.59.2.1  21-Mar-2021  thorpej Give config_found() the same variadic arguments treatment as
config_search(). This commit only adds the CFARG_EOL sentinel
to the existing config_found() calls. Conversion of config_found_sm_loc()
and config_found_ia() call sites will be in subsequent commits.

sys/dev/pci/fms.c: revision 1.50

mpu / opl: add an interface attribute to config_found() calls for these

specify an interface attribute when attaching mpu and opl devices.
the PCI devices that are the parents of these midi devices
(cmpci, eso, fms, sv, yds) have two interface attributes:
"audiobus", and also one named the same as the parent device,
eg. "cmpci" has an interface attribute named "cmpci".
we must specify the latter one to attach these children.
