Howard Mitchell 3088ef9f5d ALSA: ControlName.txt: Add 'Analogue' as a prefix for volume controls
Currently 'Playback Volume' is the correct way to express an analogue
volume control. However, this control name has initialisation defaults
applied when using 'alsactl restore' and in some cases this is not
appropriate. An example would be a control that has a selection of
0db and -6dB of gain that is intended to set the fullscale ouput
voltage of a DAC. The TI pcm512x family of DAcs have such a control.
In this case the device/driver reset defaults are preferred.

Pierre-Louis Bossart 229d043096 ALSA: core: selection of audio_tstamp type and accuracy reports
Audio timestamps can be extracted from sample counters, wall clocks,
PHC clocks (Ethernet AVB), on-demand synchronized snapshots. This
patch provides the ability to report timestamping capabilities, select
timestamp types and retrieve timestamp accuracy, if supported.
Details can be found in Documentations/sound/alsa/timestamping.txt

This functionality is introduced by reclaiming the reserved_aligned
field introduced by commit9c7066aef4a5eb8e4063de28f06c508bf6f2963a
in snd_pcm_status to provide userspace with selection/query capabilities.
Additional driver_tstamp and audio_tstamp_accuracy fields are also added.

snd_pcm_mmap_status remains a read-only structure with only
the audio timestamp value accessible from user space. The selection
of audio timestamp type is done through snd_pcm_status only

This commit does not impact ABI and does not impact the default
behavior. By default audio timestamp is aligned with hw_pointer and
reports the DMA position. Backwards compatibility is handled by using
the HDAudio wall clock for playback and the hw_ptr for all other
cases.

For timestamp selection a new STATUS_EXT ioctl is introduced with
read/write parameters. Alsa-lib will be modified to make use of
STATUS_EXT.

Takashi Iwai 2b30d411db ALSA: pcm: Add xrun_injection proc entry
This patch adds a new proc entry for PCM substreams to inject an
XRUN.  When a PCM substream is running and any value is written to its
xrun_injection proc file, the driver triggers XRUN.  This is a useful
feature for debugging XRUN and error handling code paths.

Note that this entry is enabled only when CONFIG_SND_PCM_XRUN_DEBUG is
set.

Takashi Iwai f5914908a5 ALSA: pcm: Replace PCM hwptr tracking with tracepoints
ALSA PCM core has a mechanism tracking the PCM hwptr updates for
analyzing XRUNs.  But its log is limited (up to 10) and its log output
is a kernel message, which is hard to handle.

In this patch, the hwptr logging is moved to the tracing
infrastructure instead of its own.  Not only the hwptr updates but
also XRUN and hwptr errors are recorded on the trace log, so that user
can see such events at the exact timing.

The new "snd_pcm" entry will appear in the tracing events:
  # ls -F /sys/kernel/debug/tracing/events/snd_pcm
  enable  filter  hw_ptr_error/  hwptr/  xrun/

The hwptr is for the regular hwptr update events.  An event trace
looks like:

  aplay-26187 [004] d..3  4012.834761: hwptr: pcmC0D0p/sub0: POS: pos=488, old=0, base=0, period=1024, buf=16384

"POS" shows the hwptr update by the explicit position update call and
"IRQ" means the hwptr update by the interrupt,
i.e. snd_pcm_period_elapsed() call.  The "pos" is the passed
ring-buffer offset by the caller, "old" is the previous hwptr, "base"
is the hwptr base position, "period" and "buf" are period- and
buffer-size of the target PCM substream.
(Note that the hwptr position displayed here isn't the ring-buffer
 offset.  It increments up to the PCM position boundary.)

The XRUN event appears similarly, but without "pos" field.
The hwptr error events appear with the PCM identifier and its reason
string, such as "Lost interrupt?".

The XRUN and hwptr error reports on kernel message are still left, can
be turned on/off via xrun_debug proc like before.  But the bit 3, 4, 5
and 6 bits of xrun_debug proc are dropped by this patch.  Also, along
with the change, the message strings have been reformatted to be a bit
more consistent.

Last but not least, the hwptr reporting is enabled only when
CONFIG_SND_PCM_XRUN_DEBUG is set.

Takashi Iwai 8b3dfdaf0c ALSA: hda - Adjust speaker HPF and add LED support for HP Spectre 13
HP Spectre 13 has the IDT 92HD95 codec, and BIOS seems to set the
default high-pass filter in some "safer" range, which results in the
very soft tone from the built-in speakers in contrast to Windows.
Also, the mute LED control is missing, since 92HD95 codec still has no
HP-specific fixups for GPIO setups.

This patch adds these missing features: the HPF is adjusted by the
vendor-specific verb, and the LED is set up from a DMI string (but
with the default polarity = 0 assumption due to the incomplete BIOS on
the given machine).

Takashi Iwai da96fb5b01 ALSA: hda - Fix invalid multi-io creation on VAIO-Z laptops
VAIO-Z laptops need to use the specific DAC for the speaker output
by some unknown reason although the codec itself supports the flexible
connection.  So we implemented a workaround by a new flag,
no_primary_hp, for assigning the speaker pin first.

This worked until 3.8 kernel, but it got broken because the driver
learned for a better multi-io pin mapping, and not it can assign two
mic pins for multi-io.  Since the multi-io requires to be the primary
output, the hp and two mic pins are assigned in prior to the speaker
in the end.

Although the machine has two mic pins, one of them is used as a noise-
canceling headphone, thus it's no real retaskable mic jack.  Thus, at
best, we can disable the multi-io assignment and make the parser
behavior back to the state before the multi-io.

This patch adds again a new flag, no_multi_io, to indicate that the
device has no multi-io capability, and set it in the fixup for
VAIO-Z.  The no_multi_io flag itself can be used generically, added
via a helper line, too.

The current fixup for dell-bios model with STAC9228 codec contains the
override of pin 0x0c for analog mic.  But this is actually just adding

Meanwhile, for a possible regression, keep the old configuration as
model=dell-bios-amic, so that people can test it again quickly.

This reverts commit 6ab317419c.

The commit [6ab317419c: ALSA: hda - Allow power_save_controller option

it can override the driver capability.  This assumed that this option
is rarely changed dynamically unlike power_save option.  Too naive.

It turned out that the user-space power-management tool tries to set
power_save_controller option to 1 together with power_save option
without knowing what's actually doing.  This enabled forcibly the
runtime PM of the controller,  which is known to be broken om many
chips thus disabled as default.

So, the only sane fix is to revert this commit again.  It was intended
to ease debugging/testing for runtime PM enablement, but obviously we
need another way for it.

Takashi Iwai f811c3cf8f ALSA: hda - Consolidate add_in_jack_modes and add_out_jack_modes hints
There is no big merit to distinguish these two hints.  Instead, just
have a single flag, add_jack_modes, for creating the jack mode enum
ctls for both I/O directions.

The hint string parser code is left and translated as add_jack_modes
just for keeping compatibility.

Takashi Iwai 967303dabc ALSA: hda - Add the generic Headphone Mic feature
This patch improves the generic parser code to allow to set up the
headphone jack as a mic input.  User can enable this feature by giving
hp_mic hint string.

The former shared hp/mic feature for the single built-in mic is still
retained.  This detection can be disabled now via hp_mic_detect hint
string, too.

Takashi Iwai 1dac6695c6 ALSA: hda - Allow to pass position_fix=0 explicitly
Set the default value of position_fix -1, and allow user passing
position_fix=0 explicitly to set the "auto" position-fix mode.
Otherwise the auto mode may be switched to others like COMBO of
VIACOMBO when the controller prefers it, thus user can't set the auto
mode any longer.

Also updated the documentation appropriately, too.
