hdac: Defer interrupt allocation in hdac_attach()

hdac_attach() registers an interrupt handler before allocating various
driver resources which are accessed by the interrupt handler. On some
platforms we observe what appear to be spurious interrupts upon a cold
boot, resulting in panics.

Partially work around the problem by deferring irq allocation until
after other resources are allocated. I think this is not a complete
solution, but is correct and sufficient to work around the problems
reported in the PR.

sound/hda: fix interrupt handler endless loop after r362294

Not all interrupt sources that affect CIS bit were acknowledged.
Specifically, bits in STATESTS (aka WAKESTS) were left set.

The fix is to disable WAKEEN and clear STATESTS bits before the HDA
interrupt is enabled. This way we should never get any STATESTS bits.

I also added placeholders for all event bits that we currently do not
enable, do not handle and do not clear. This might get useful when / if
we enable any of them.

hdac_intr_handler: keep working until global interrupt status clears

It is plausible that the hardware interrupts a host only when GIS goes
from zero to one. GIS is formed by OR-ing multiple hardware statuses,
so it's possible that a previously cleared status gets set again while
another status has not been cleared yet. Thus, there will be no new
interrupt as GIS always stayed set. If we don't re-examine GIS then we
can leave it set and never get another interrupt again.

Without this change I frequently saw a problem where snd_hda would stop
working. Setting dev.hdac.1.polling=1 would bring it back to life and
afterwards I could set polling back to zero. Sometimes the problem
started right after a boot, sometimes it happened after resuming from
S3, frequently it would occur when sound output and input are active
concurrently (such as during conferencing). I looked at HDAC_INTSTS
while the sound was not working and I saw that both HDAC_INTSTS_GIS and
HDAC_INTSTS_CIS were set, but there were no interrupts.

I have collected some statistics over a period of several days about how
many loops (calls to hdac_one_intr) the new code did for a single
interrupt:
+--------+--------------+
|Loops |Times Happened|
+--------+--------------+
|0 |301 |
|1 |12857746 |
|2 |280 |
|3 |2 |
|4+ |0 |
+--------+--------------+
I believe that previously the sound would get stuck each time we had to loop
more than once.

sys/dev: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I

prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Slightly fix bidirectional stream number allocation.

This logic is still imperfect, since it allows at most 15 bidirectional
streams out of 30 allowed by specification, but at least now those should
work better. On the other side I don't remember I ever saw controller
supporting the bidirectional streams, so this is likely a nop change.

Improve HDMI/DisplayPort audio support in snd_hda(4):

- Enable and handle unsolicited responses from digital display pins,

- Fetch ELD data, describing connected digital display device audio
capabilities. These data not really used at the moment (user is not
denied to use audio formats not supported by the device), only printed to
verbose logs. But they are useful for debugging. The fact that ELD was
received tells that HDMI link was established and video driver enabled
HDMI audio passthrough. Some old chips may not return ELD, so lack of it
is not necessary a problem.
- Add some more points to CODEC configuration sequence:
- For converter widgets, supporting more then two channels (HDMI/DP
converter widgets support 8), set number of channels to handle.
- For digital display pins (HDMI/DP) fill audio infoframe, reporting
connected device about number of channels and speakers allocation.
- For digital display pins (HDMI/DP) set mapping between channels seen
by software and channels transferred via HDMI/DisplayPort.
- Allow more audio formats, not used for analog connections because of
stereo pairs orientation, but easily applicable to HDMI/DisplayPort: 2.1,
3.0, 3.1, 4.1, 5.0, 6.0, 6.1, 7.0. That list may be filtered later using

Major snd_hda driver rewrite:
- Huge old hdac driver was split into three independent pieces: HDA
controller driver (hdac), HDA CODEC driver (hdacc) and HDA sudio function
driver (hdaa).
- Support for multichannel recording was added. Now, as specification
defines, driver checks input associations for pins with sequence numbers
14 and 15, and if found (usually) -- works as before, mixing signals
together. If it doesn't, it configures input association as multichannel.
- Signal tracer was improved to look for cases where several DACs/ADCs in
CODEC can work with the same audio signal. If such case found, driver
registers additional playback/record stream (channel) for the pcm device.
- New controller streams reservation mechanism was implemented. That
allows to have more pcm devices then streams supported by the controller
(usually 4 in each direction). Now it limits only number of simultaneously
transferred audio streams, that is rarely reachable and properly reported
if happens.
- Codec pins and GPIO signals configuration was exported via set of
writable sysctls. Another sysctl dev.hdaa.X.reconfig allows to trigger
driver reconfiguration in run-time.
- Driver now decodes pins location and connector type names. In some cases
it allows to hint user where on the system case connectors, related to the
pcm device, are located. Number of channels supported by pcm device,
reported now (if it is not 2), should also make search easier.
- Added workaround for digital mic on some Asus laptops/netbooks.

Make the newbus subsystem Giant free by adding the new newbus sxlock.
The newbus lock is responsible for protecting newbus internIal structures,
device states and devclass flags. It is necessary to hold it when all
such datas are accessed. For the other operations, softc locking should
ensure enough protection to avoid races.

Newbus lock is automatically held when virtual operations on the device
and bus are invoked when loading the driver or when the suspend/resume
take place. For other 'spourious' operations trying to access/modify
the newbus topology, newbus lock needs to be automatically acquired and
dropped.

For the moment Giant is also acquired in some key point (modules subsystem)
in order to avoid problems before the 8.0 release as module handlers could
make assumptions about it. This Giant locking should go just after
the release happens.

Please keep in mind that the public interface can be expanded in order
to provide more support, if there are really necessities at some point
and also some bugs could arise as long as the patch needs a bit of
further testing.

instead of /dev/mixer. Special "bypass" mode is enabled through
/dev/mixer which will automatically detect if the adjustment is made
through /dev/mixer and forward its request to this private volume
controller. Changes to this volume object will not interfere with
other channels.

Requirements:
- SNDCTL_DSP_[GET|SET][PLAY|REC]_VOL are newer ioctls (OSSv4) which
require specific application modifications (preferred).
- No modifications required for using bypass mode, so applications
like mplayer or xmms should work out of the box.

Kernel hints:
- hint.pcm.%d.vpc (0 = disable vpc).

Kernel sysctls:
- hw.snd.vpc_mixer_bypass (default: 1). Enable or disable /dev/mixer
bypass mode.
- hw.snd.vpc_autoreset (default: 1). By default, closing/opening
/dev/dsp will reset the volume back to 0 db gain/attenuation.
Setting this to 0 will preserve its settings across device
closing/opening.
- hw.snd.vpc_reset (default: 0). Panic/reset button to reset all
volume settings back to 0 db.
- hw.snd.vpc_0db (default: 45). 0 db relative to linear mixer value.

2 High quality fixed-point Bandlimited SINC sampling rate converter,
based on Julius O'Smith's Digital Audio Resampling -
http://ccrma.stanford.edu/~jos/resample/. It includes a filter design
script written in awk (the clumsiest joke I've ever written)
- 100% 32bit fixed-point, 64bit accumulator.
- Possibly among the fastest (if not fastest) of its kind.
- Resampling quality is tunable, either runtime or during kernel
compilation (FEEDER_RATE_PRESETS).
- Quality can be further customized during kernel compilation by
defining FEEDER_RATE_PRESETS in /etc/make.conf.

Kernel sysctls:
- hw.snd.feeder_rate_quality.
0 - Zero-order Hold (ZOH). Fastest, bad quality.
1 - Linear Interpolation (LINEAR). Slightly slower than ZOH,
better quality but still does not eliminate aliasing.
2 - (and above) - Sinc Interpolation(SINC). Best quality. SINC
quality always start from 2 and above.

Rough quality comparisons:
- http://people.freebsd.org/~ariff/z_comparison/

3 Bit-perfect mode. Bypasses all feeder/dsp effects. Pure sound will be
directly fed into the hardware.

4 Parametric (compile time) Software Equalizer (Bass/Treble mixer). Can
be customized by defining FEEDER_EQ_PRESETS in /etc/make.conf.

5 Transparent/Adaptive Virtual Channel. Now you don't have to disable
vchans in order to make digital format pass through. It also makes
vchans more dynamic by choosing a better format/rate among all the
concurrent streams, which means that dev.pcm.X.play.vchanformat/rate
becomes sort of optional.

6 Exclusive Stream, with special open() mode O_EXCL. This will "mute"
other concurrent vchan streams and only allow a single channel with
O_EXCL set to keep producing sound.

Other Changes:
* most feeder_* stuffs are compilable in userland. Let's not
speculate whether we should go all out for it (save that for
FreeBSD 16.0-RELEASE).
* kobj signature fixups, thanks to Andriy Gapon <avg@freebsd.org>
* pull out channel mixing logic out of vchan.c and create its own
feeder_mixer for world justice.
* various refactoring here and there, for good or bad.

My massive snd_hda driver update.

Because of using more clear and same time more functional codec parser
new driver is able to handle more codecs, use them better then before and
without most of previous quirks. All of tested codecs itself manage playback,
record, input mixing and monitoring quite fine. In all of investigated
trouble cases problem was found or in nonstandard codec usage or incorrect
codec configuration made by BIOS. Most of that cases could be fixed using
device hints, some of which are already included to the driver.

New driver supports multiple codecs per HDA bus, multiple audio function
groups per codec and multiple logical sound devices per audio function group.
So don't worry when you get several PCM devices instead of one, it is normal.
It is usual situation with powerful codecs to provide, for example, 3 PCM
devices: one for 7.1 playback and main recording, one for headset and one
for digital SPDIF I/O.

New driver implements Universal Audio Architecture (UAA) much better then
previous one. Most information about recommended codec usage now taken from
the codec configuration registers initialized by BIOS. User may alter that
configuration using device hints to reconfigure logical audio devices to
his needs in a very broad range up to the limits of the codec functionality.

New driver supports digital PCM playback and AC3 pass-through. I am not sure
about completeness of this implementation, but I have several success stories
including my own. Vchans subsystem does not support AC3 pass-through so it
had to be disabled for that devices at this moment.

New driver is ready for multichannel playback, but until our OSS is unable
to use this it will just duplicate same stereo stream into all channel
pairs.

New driver supports suspend/resume. I am unable to really test this part
myself, but I have got several success stories.

Driver has very informative verbose boot messages. So if you have any
questions or problems - enable and read them first.

Despite several examples in the kernel, the third argument of
sysctl_handle_int is not sizeof the int type you want to export.
The type must always be an int or an unsigned int.

Remove the instances where a sizeof(variable) is passed to stop
people accidently cut and pasting these examples.

In a few places this was sysctl_handle_int was being used on 64 bit
types, which would truncate the value to be exported. In these
cases use sysctl_handle_quad to export them and change the format
to Q so that sysctl(1) can still print them.

Welcome to Once-a-year Sound Mega-Commit. Enjoy numerous updates and fixes
in every sense.

General
-------

- Multichannel safe, endian safe, format safe
* Large part of critical pcm filters such as vchan.c, feeder_rate.c,
feeder_volume.c, feeder_fmt.c and feeder.c has been rewritten so that
using them does not cause the pcm data to be converted to 16bit little
endian.
* Macrosses for accessing pcm data safely are defined within sound.h in
the form of PCM_READ_* / PCM_WRITE_*
* Currently, most of them are probably limited for mono/stereo handling,
but the future addition of true multichannel will be much easier.

- Low latency operation
* Well, this require lot more works to do not just within sound driver,
but we're heading towards right direction. Buffer/block sizing within
channel.c is rewritten to calculate precise allocation for various
combination of sample/data/rate size. As a result, applying correct
SNDCTL_DSP_POLICY value will achive expected latency behaviour simmilar
to what commercial 4front driver do.
* Signal handling fix. ctrl+c of "cat /dev/zero > /dev/dsp" does not
result long delay.
* Eliminate sound truncation if the sound data is too small.
DIY:
1) Download / extract
http://people.freebsd.org/~ariff/lowlatency/shortfiles.tar.gz
2) Do a comparison between "cat state*.au > /dev/dsp" and
"for x in state*.au ; do cat $x > /dev/dsp ; done"
- there should be no "perceivable" differences.
Double close for PR kern/31445.

CAVEAT: Low latency come with (unbearable) price especially for poorly
written applications. Applications that trying to act smarter
by requesting (wrong) blocksize/blockcount will suffer the most.
