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.

Since audio code is mp safe, establish isa and pci audio interrupts

ok kettenis

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

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.

discussed with ratchov, deraadt

configure conversion for the correct direction. I guess no one has
ever tried recording big endian samples with fms.

First pass at removing clauses 3 and 4 from NetBSD licenses.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

OK deraadt@

use ac97 default parameters for these ac97 based drivers.

this makes the emulation expansion factor 1 by default since there's no
emulation. previously the factor was 2 because these drivers emulate
8-bit ulaw playback with 16-bit linear encodings. having a factor
other than 1 by default creates block size and hiwat/lowat issues
with applications that set the block size and hiwat before other
parameters.

Since audio code is mp safe, establish isa and pci audio interrupts

interrupt handlers from waiting the global kernel_lock possibly (hold

ok kettenis

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

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.

use ac97 default parameters for these ac97 based drivers.

this makes the emulation expansion factor 1 by default since there's no
emulation. previously the factor was 2 because these drivers emulate
8-bit ulaw playback with 16-bit linear encodings. having a factor
other than 1 by default creates block size and hiwat/lowat issues
with applications that set the block size and hiwat before other
parameters.

in the kernel virtual memory. As we only access the first 256 byte it is
of no use to map 128MB of kvm.

branches: 1.2.6;
Add $OpenBSD$ tags.

new auvia and fms drivers from netbsd (testing requests sent out, since i cannot find any of these devices)

Make room for a cookie argument passed to audio_attach_mi(). Currently
unused but intended to be used to correlate audio and wskbd devices.

ok ratchov@

Set free(9) size argument. From Michael W. Bombardieri <mb at ii.net>.
Thanks.

Remove unused getdev() audio driver functions.

Remove drain(), query_encoding(), mappage() and get_default_params()
methods from all audio drivers and from the audio_if structure as they
are never called.

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

ok armani@

add a size argument to free. will be used soon, but for now default to 0.
after discussions with beck deraadt kettenis.

ansify some function definitions.
no functional change.

ok sthen@

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.

ok kettenis

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

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.

discussed with ratchov, deraadt

configure conversion for the correct direction. I guess no one has
ever tried recording big endian samples with fms.

First pass at removing clauses 3 and 4 from NetBSD licenses.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

OK deraadt@

use ac97 default parameters for these ac97 based drivers.

this makes the emulation expansion factor 1 by default since there's no
emulation. previously the factor was 2 because these drivers emulate
8-bit ulaw playback with 16-bit linear encodings. having a factor
other than 1 by default creates block size and hiwat/lowat issues
with applications that set the block size and hiwat before other
parameters.

ok ratchov@

allow low level audio drivers to specify a default sample format,
instead of 8-bit mono mulaw @ 8kHz.

this is just the infrastructure; no drivers are specifying a default
yet.

ok ratchov@, deanna@

do not provide round_buffer if not needed unless explained why in comments

make sure round_blocksize does not produce 0 after alignment

strcpy/sprintf cleanup of sys/dev. miod@, deraadt@ says to commit.

Add a simplistic table driven lookup routine and use it where appropriate.

Remove more '\n's from panic() statements. From Chris Kuethe.

there is no need to store ioaddr/iosize into the softc

oops

fix the fms attachment printfs and move out the radio parts to the fmsradio.c; from jumbo@ and some fixes from mickey@

tuner driver for the fms cards.
attach radio at the fms(4), instead of a separate device,
which would never work out fine.
from Vladimir Popov <jumbo@narod.ru>
rework the radio config stuff (radio at radiobus, instead of radio at radio),
allowing to tag source files in the files.* files w/ radio attribute.
from mickey@

Final __P removal plus some cosmetic fixups

First round of __P removal in sys

make all audio drivers use the new allocm and round_buffersize decl's.
will ease porting, and generally cleans up a bit

branches: 1.5.2;
Change the audio_hm_if->mappage interface to return paddr_t and take off_t
as the mmap offset.

Change pci_intr_map to take pci_attach_args as an argument.
All callers actually took all arguments to pci_intr_map from pci_attach_args
structs, so this simplifies code.
This also allows more complicated interrupt assignment schemes like the one
on sparc64.

This makes sparc64 pci interrupts work.

Inspired by the same change in NetBSD.

Make pci_mapreg_map take an extra argument where we can
put a size limitation of the PCI region to map. That makes the PERC 3/Di
raid controller usable, as it publishes too much PCI memory for us to map
in the kernel virtual memory. As we only access the first 256 byte it is
of no use to map 128MB of kvm.
