      ALSA: hda - Add DP-MST support for NVIDIA codecs · 5398e94f
      由 Nikhil Mahale 提交于 
      This patch adds DP-MST support for GK104+ NVIDIA codecs.

GK104+ NVIDIA codecs support DP-MST audio. These codecs have 4
output converters and 4 pin widgets, with 4 device entries per pin
widget for a total of 16 device entries.

This patch moves the existing patch_nvhdmi() definition to
patch_nvhdmi_legacy(), used by pre-GK104 NVIDIA codecs. Redefine
patch_nvhdmi() to enable DP-MST support by setting codec->dp_mst and
spec->dyn_pcm_assign.

Introduce fresh logic for dynamic pcm assignment, making
sure that new pcm assignments are compatible with the legacy static
per_pin-pmc assignment that existed in the days before DP-MST.

      ALSA: hda - Add DP-MST support for non-acomp codecs · 9c32fea8
      由 Nikhil Mahale 提交于 
      This patch make it possible for non-acomp codecs to set
dyn_pcm_assign/dp_mst and get DP-MST audio support.

Document change notification HDA040-A for the Intel High Definition
Audio 1.0a specification introduces a Device Select verb for Digital
Display Pin Widgets that are multi-stream capable. This verb selects
a Device Entry that is used by subsequent Pin Widget verbs.
Once the Device Entry is selected, all subsequent Pin Widget verbs
controlling the sink device will be directed to the selected Device
Entry until the Device Select verb is updated with a new value.

These Pin Widget verbs include:

  * Connection Select
  * Get Connection List Entry
  * Amplifier Gain/Mute
  * Power State
  * Pin Widget Control
  * ELD Data
  * DIP-Size
  * DIP-Index
  * DIP-Data
  * DIP-XmitCtrl
  * Content Protection Control
  * ASP Channel Mapping

This patch adds calls to snd_hda_set_dev_select() to direct each of
these Pin Widget control verbs to the correct Device Entry.

snd_hda_get_connections() does not return per-device connection
list, therefore make use snd_hda_get_raw_connections() instead of
snd_hda_get_connections().

      ALSA: hda - Add DP-MST jack support · 5204a05d
      由 Nikhil Mahale 提交于 
      This patch adds DP-MST jack support which will be used on NVIDIA
platforms. Today, DP-MST audio is supported only if the codec has
acomp support. This patch makes it possible to add DP-MST support
for non-acomp codecs.

For the codecs supporting DP-MST audio, each pin can contain several
device entries. Each device entry is a virtual pin, described by
pin_nid and dev_id in struct hdmi_spec_per_pin. For monitor hotplug
event handling, non-acomp codecs enable and register jack-detection
for every hdmi_spec_per_pin.

This patch updates every relevant function in hda_jack.h and its
implementation in hda_jack.c, to consider dev_id along with pin_nid.

Changes to the HD Audio specification to support DP-MST audio are
described in the Intel Document Change Notification (DCN) number
HDA040-A.

From HDA040-A, "For the case of multi stream capable Digital Display
Pin Widget, [the Get Pin Sense verb] can be used to read a specific
Device Entry state as reported in Get Device List Entry verb." This
patch updates the read_pin_sense() function to take the dev_id as an
argument and pass it as a parameter to the Get Pin Sense verb.

Bits 15 through 20 from the Unsolicited Response for intrinsic
events contain the index of the Device Entry that generated the
event. This patch updates the Unsolicited Response event handlers to
extract the device entry index from the response and pass it to
snd_hda_jack_tbl_get_from_tag().

This patch updates snd_hda_jack_tbl_new() to take a dev_id argument
and store it in the jack structure, and to make sure not to generate
a different tag when called more than once for the same nid.

      ALSA: hda - Fix mutex deadlock in HDMI codec driver · 302d5a80
      由 Takashi Iwai 提交于 
      The commit ade49db3 ("ALSA: hda/hdmi - Allow audio component for
AMD/ATI and Nvidia HDMI") introduced the spec->pcm_lock mutex lock to
the whole generic_hdmi_init() function for avoiding the race with the
audio component registration.  However, this caused a dead lock when
the unsolicited event is handled without the audio component, as the
codec gets runtime-resumed in hdmi_present_sense() which is already
inside the spec->pcm_lock in its caller.

For avoiding this deadlock, add a new mutex only for the audio
component binding that is used in both generic_hdmi_init() and the
audio notifier registration where the jack callbacks are handled /
re-registered.

      ALSA: hda/hdmi - implement mst_no_extra_pcms flag · 2a2edfbb
      由 Kai Vehmanen 提交于 
      To support the DP-MST multiple streams via single connector feature,
the HDMI driver was extended with the concept of backup PCMs. See
commit 9152085d ("ALSA: hda - add DP MST audio support").

This implementation works fine with snd_hda_intel.c as PCM topology
is fully managed within the single driver.

When the HDA codec driver is used from ASoC components, the concept
of backup PCMs no longer fits. For ASoC topologies, the physical
HDMI converters are presented as backend DAIs and these should match
with hardware capabilities. The ASoC topology may define arbitrary
PCMs (i.e. frontend DAIs) and have processing elements before eventual
routing to the HDMI BE DAIs. With backup PCMs, the link between
FE and BE DAIs would become dynamic and change when monitors are
(un)plugged. This would lead to modifying the topology every time
hotplug events happen, which is not currently possible in ASoC and
there does not seem to be any obvious benefits from this design.

To overcome above problems and enable the HDMI driver to be used
from ASoC, this patch adds a new mode (mst_no_extra_pcms flags) to
patch_hdmi.c. In this mode, the codec driver does not assume
the backup PCMs to be created.

      Add Acer Aspire Ethos 8951G model quirk · 00066e97
      由 Sergey Bostandzhyan 提交于 
      This notebook has 6 built in speakers for 5.1 surround support, however
only two got autodetected and have also not been assigned correctly.

This patch enables all speakers and also fixes muting when headphones are
plugged in.

The speaker layout is as follows:

pin 0x15 Front Left / Front Right
pin 0x18 Front Center / Subwoofer
pin 0x1b Rear Left / Rear Right (Surround)

The quirk will be enabled automatically on this hardware, but can also be
activated manually via the model=aspire-ethos module parameter.

Caveat: pin 0x1b is shared between headphones jack and surround speakers.
When headphones are plugged in, the surround speakers get muted
automatically by the hardware, however all other speakers remain
unmuted. Currently it's not possible to make use of the generic automute
function in the driver, because such shared pins are not supported.

If we would change the pin settings to identify the pin as headphones,
the surround channel and thus the ability to select 5.1 profiles would
get lost.

This quirk solves the above problem by monitoring jack state of 0x1b and
by connecting/disconnecting all remaining speaker pins when something
gets plugged in or unplugged from the headphones jack port.
