Make audio(9) get_props() optional, remove it from duplex drivers
The property bits of audio(9) are obsolete and ought to be removed completely.
sys/dev/audio.c:audio_open() currently uses get_props() to bail out if read *and* write was requested on a non-duplex driver.
Drivers that currently support playing but not recording need adjustment before the API can be cleaned up.
Drivers that advertise themselves as full duplex, i.e. those that always return AUDIO_PROP_FULLDUPLEX unconditionally in their get_props() currently always succeed this check.
As this is the only property, losen audio_open()'s DIAGNOSTIC check and only do the duplex check if the driver provides get_props().
This allows for simple removal of get_props() from full-duplex drivers without adding any other code or without changing functionality.
This includes all audio drivers under sys/dev/pci/ (maestro(4) being the only unfinished exception here).
Other drivers as well as the API change can then follow in smaller diffs.
This builds on amd64, arm64, i386, macppc and sparc64. amd64 with azalia(4) still plays, records as well as plays and records at the same time on my X230 as tested with
$ aucat -i play.wav [-o rec.wav]

Use C99 struct init for struct audio_hw_if
This audio(9) struct will lose a member, but drivers init their struct quite inconsistently, most pre-C99 style.
Use C99 style everywhere, to get rid of all annoying differences and allow for easy member removals/additions: - don't change current order of members - no explicit NULL members - no comments or blank lines - trailing comma in last member line
GENERIC.MP builds fine with this on arm64, amd64, i386 and sparc64.

Remove unused AUDIO_PROP_{MMAP,INDEPENDENT}

Delete unused ioctls and associated macros. Move macros that are still used internally by low-level drivers from sys/audioio.h to dev/audio_if.h instead of deleting them.

Since critical sections remain the same, calls to splraise/spllower can be safely replaced by calls to mtx_enter/mtx_leave with two exceptions: (1) mutexes are not reentrant (the inner splraise is thus removed), and (2) we're not allowed to sleep with a mutex (either msleep is used or the mutex is released before sleeping).

Introduce a global interrupt-aware mutex protecting data structures (including sound-card registers) from concurent access by syscall and interrupt code-paths. Since critical sections remain the same, calls to splraise/spllower can be safely replaced by calls to mtx_enter/mtx_leave with two exceptions: (1) mutexes are not reentrant (the inner splraise is thus removed), and (2) we're not allowed to sleep with a mutex (either msleep is used or the mutex is released before sleeping).

Use C99 struct init for struct audio_hw_if
This audio(9) struct will lose a member, but drivers init their struct quite inconsistently, most pre-C99 style.
Use C99 style everywhere, to get rid of all annoying differences and allow for easy member removals/additions: - don't change current order of members - no explicit NULL members - no comments or blank lines - trailing comma in last member line
GENERIC.MP builds fine with this on arm64, amd64, i386 and sparc64.

Reimplement the audio driver in a simpler way, removing unused/unusable functionality. Same API and ABI except for the removed bits and no behaviour change for programs using libsndio. With help from armani@ and mpi@, thanks.
but remained defined and set in drivers.
and the following merely moved them when they were dead code already:
commit 9215aa3dfad387bca877a805534df6dcfe8722eb Author: ratchov <ratchov@openbsd.org> Date: Wed Aug 31 07:22:43 2016 +0000
Delete unused ioctls and associated macros. Move macros that are still used internally by low-level drivers from sys/audioio.h to dev/audio_if.h instead of deleting them.
None of this is used in base or ports; codesearch.debian.net only shows AUDIO_PROP_{CAPTURE,PLAYBACK} in firefox-esr, mozjs and cubeb.
ratchov points out that audio_if.h and audioio.h are private interfaces and the codesearch shows SunOS and NetBSD bits (#ifdef'd out on OpenBSD).

Introduce a global interrupt-aware mutex protecting data structures (including sound-card registers) from concurent access by syscall and interrupt code-paths. Since critical sections remain the same, calls to splraise/spllower can be safely replaced by calls to mtx_enter/mtx_leave with two exceptions: (1) mutexes are not reentrant (the inner splraise is thus removed), and (2) we're not allowed to sleep with a mutex (either msleep is used or the mutex is released before sleeping).

audio(9) says low level drivers are allowed to change the requested values of the audio_params structure during AUDIO_SETINFO if the hardware cannot be set to exactly the requested mode.
some drivers do this sometimes. others always return EINVAL if there isn't an exact match.
be more consistent. only return EINVAL if an absurd parameter was requested, otherwise return a supported set of parameters, as close as possible to what was requested.

add two new members to structs audio_encoding and audio_prinfo. for both structs, the new members are 'bps' and 'msb', which describe the number of bytes per sample and data alignment in the sample, respectively. drivers must properly set these fields in the 'query_encoding', 'set_parameters' and 'get_default_params' hardware interface methods.

audio(9) says low level drivers are allowed to change the requested values of the audio_params structure during AUDIO_SETINFO if the hardware cannot be set to exactly the requested mode.
some drivers do this sometimes. others always return EINVAL if there isn't an exact match.
be more consistent. only return EINVAL if an absurd parameter was requested, otherwise return a supported set of parameters, as close as possible to what was requested.

- Remove sys/cdefs.h header. - Make use of pci_matchbyid(). - Replace magic number with PCI_MAPREG_START for the PCI BAR. - Remove redundant code to enable PCI bus mastering which is already dealt with by pci_mapreg_map().

Remove all audio format conversion code from the kernel (btw holding the kernel_lock), as we already do better conversions in user-mode. Yet, no need for every single driver to fiddle with the conversion code as they are done transparently by common MI code. With help from armani and miod, support from mpi

Add a DVACT_WAKEUP op to the *_activate() API. This is called after the kernel resumes normal (non-cold, able to run processes, etc) operation. Previously we were relying on specific DVACT_RESUME op's in drivers creating callback/threads themselves, but that has become too common, indicating the need for a built-in mechanism. ok dlg kettenis, tested by a sufficient amount of people

Since audio code is mp safe, establish isa and pci audio interrupts with the IPL_MPSAFE flag. In certain circumstances, this prevents interrupt handlers from waiting the global kernel_lock possibly (hold by slower code) to be released.

Introduce a global interrupt-aware mutex protecting data structures (including sound-card registers) from concurent access by syscall and interrupt code-paths. Since critical sections remain the same, calls to splraise/spllower can be safely replaced by calls to mtx_enter/mtx_leave with two exceptions: (1) mutexes are not reentrant (the inner splraise is thus removed), and (2) we're not allowed to sleep with a mutex (either msleep is used or the mutex is released before sleeping).
ok and help from kettenis, a lot of work from armani

Remove config_activate() and DVACT_ACTIVATE. PCMCIA's the only thing that's ever used it, and it's long since been changed to use DVACT_{QUIESCE,SUSPEND,RESUME} instead.

Since the changes in neo(4) work, it is very likely that the exact same mechnical changes work in these drivers too. Testing can occur after this commit.
