      ALSA: hda - Refresh sysfs at snd_hda_codec_update_widgets() · 9dcc144b
      由 Takashi Iwai 提交于 
      In the commit [fa4f18b4: ALSA: hda - Refresh widgets sysfs at
probing Haswell+ HDMI codecs], snd_hdac_refresh_widget_sysfs() is
explicitly called in the codec driver.  But this results in refreshing
twice, as snd_hdac_refresh_widget_sysfs() itself calls
snd_hdac_refresh_widgets() function.

Instead, we can replace the call in snd_hda_codec_update_widgets()
with snd_hdac_refresh_widget_sysfs().  This also fixes the missing
sysfs update for ca0132, too.

      ALSA: core: Remove child proc file elements recursively · c560a679
      由 Takashi Iwai 提交于 
      This patch changes the way to manage the resource release of proc
files: namely, let snd_info_free_entry() freeing the whole children.

This makes it us possible to drop the snd_device_*() management.  Then
snd_card_proc_new() becomes merely a wrapper to
snd_info_create_card_entry().

Together with this change, now you need to call snd_info_free_entry()
for a proc entry created via snd_card_proc_new(), while it was freed
via snd_device_free() beforehand.

      ALSA: hda - Work around races of power up/down with runtime PM · 664c7155
      由 Takashi Iwai 提交于 
      Currently, snd_hdac_power_up()/down() helpers checks whether the codec
is being in pm (suspend/resume), and skips the call of runtime get/put
during it.  This is needed as there are lots of power up/down
sequences called in the paths that are also used in the PM itself.  An
example is found in hda_codec.c::codec_exec_verb(), where this can
power up the codec while it may be called again in its power up
sequence, too.

The above works in most cases, but sometimes we really want to wait
for the real power up.  For example, the control element get/put may
want explicit power up so that the value change is assured to reach to
the hardware.   Using the current snd_hdac_power_up(), however,
results in a race, e.g. when it's called during the runtime suspend is
being performed.  In the worst case, as found in patch_ca0132.c, it
can even lead to the deadlock because the code assumes the power up
while it was skipped due to the check above.

For dealing with such cases, this patch makes snd_hdac_power_up() and
_down() to two variants: with and without in_pm flag check.  The
version with pm flag check is named as snd_hdac_power_up_pm() while
the version without pm flag check is still kept as
snd_hdac_power_up().  (Just because the usage of the former is fewer.)

Then finally, the patch replaces each call potentially done in PM with
the new _pm() variant.

In theory, we can implement a unified version -- if we can distinguish
the current context whether it's in the pm path.  But such an
implementation is cumbersome, so leave the code like this a bit messy
way for now...

      ALSA: hda - Use regmap for command verb caches, too · a551d914
      由 Takashi Iwai 提交于 
      Like the previous patches, this patch converts also to the regmap, at
this time, the cached verb writes are the target.  But this conversion
needs a bit more caution than before.

- In the old code, we just record any verbs as is, and restore them at
  resume.  For the regmap scheme, this doesn't work, since a few verbs
  like AMP or DIGI_CONVERT are asymmetrical.  Such verbs are converted
  either to the dedicated function (snd_hda_regmap_xxx_amp()) or
  changed to the unified verb.

- Some verbs have to be declared as vendor-specific ones before
  accessing via regmap.

Also, the minor optimization with codec->cached_write flag is dropped
in a few places, as this would confuse the operation.  Further
optimizations will be brought in the later patches, if any.

This conversion ends up with a drop of significant amount of codes,
mostly the helper codes that are no longer used.

      ALSA: hda - Use regmap for amp accesses · eeecd9d1
      由 Takashi Iwai 提交于 
      This patch converts the amp access functions to the regmap helpers.
The amp values were formerly cached in the own hash table.  Now it's
dropped by the regmap's cache.

The only tricky conversion is snd_hda_codec_amp_init().  This function
shouldn't do anything if the amp was already initialized.  For
achieving this behavior, a value is read once at first temporarily in
the cache-only mode.  Only if it returns an error,  i.e. the item
still doesn't exist in the cache, it proceeds to the update.

      ALSA: hda - Allocate hda_pcm objects dynamically · bbbc7e85
      由 Takashi Iwai 提交于 
      So far, the hda_codec object kept the hda_pcm list in an array, and
the codec driver was expected to assign the array.  However, this
makes the object life cycle management harder, because the assigned
array is freed at the codec driver detach while it might be still
accessed by the opened streams.

In this patch, we allocate each hda_pcm object dynamically and manage
it as a linked list.  Each object has a kref refcount, and both the
codec driver binder and the PCM open/close touches it, so that the
object won't be freed while in use.

      ALSA: hda - Bind codecs via standard bus · d8a766a1
      由 Takashi Iwai 提交于 
      Now we create the standard HD-audio bus (/sys/bus/hdaudio), and bind
the codec driver with the codec device over there.  This is the first
step of the whole transition so that the changes to each codec driver
are kept as minimal as possible.

Each codec driver needs to register hda_codec_driver struct containing
the currently existing preset via the new helper macro
module_hda_codec_driver().  The old hda_codec_preset_list is replaced
with this infrastructure.  The generic parsers (for HDMI and other)
are also included in the preset with the special IDs to bind
uniquely.

In HD-audio core side, the device binding code is split to
hda_bind.c.  It provides the snd_hda_bus_type implementation to match
the codec driver with the given codec vendor ID.  It also manages the
module auto-loading by itself like before: when the matching isn't
found, it tries to probe the corresponding codec modules, and finally
falls back to the generic drivers.  (The special ID mentioned above is
set at this stage.)

The only visible change to outside is that the hdaudio sysfs entry now
appears in /sys/bus/devices, not as a sound class device.

More works to move the suspend/resume and remove ops will be
(hopefully) done in later patches.

      ALSA: hda - hdmi: Fix missing ELD change event on plug/unplug · 6acce400
      由 Anssi Hannula 提交于 
      The ELD ALSA control change event is sent by hdmi_present_sense() when
eld_changed is true.

Currently, it is only true when the ELD buffer contents have been
modified. However, the user-visible ELD controls also change to a
zero-length value and back when eld_valid is unset/set, and no event is
currently sent in such cases (such as when unplugging or replugging a
sink).

Fix the code to always set eld_changed if eld_valid value is changed,
and therefore to always send the change event when the user-visible
value changes.

      ALSA: hda - Allow multiple callbacks for jack · 1a4f69d5
      由 Takashi Iwai 提交于 
      So far, hda_jack infrastructure allows only one callback per jack, and
this makes things slightly complicated when a driver wants to assign
multiple tasks to a jack, e.g. the standard auto-mute with a power
up/down sequence.  This can be simplified if the hda_jack accepts
multiple callbacks.

This patch is such an extension: the callback-specific part (the
function and private_data) is split to another struct from
hda_jack_tbl, and multiple such objects can be assigned to a single
hda_jack_tbl entry.

The new struct hda_jack_callback is passed to each callback function
now, thus the patch became bigger than expected.  But these changes
are mostly trivial.

      ALSA: hda - Get rid of action field from struct hda_jack_tbl · 62f949bf
      由 Takashi Iwai 提交于 
      The action value assigned to each hda_jack_tbl entry is mostly
superfluous.  The actually used values are either the widget NID or a
value specific to the callback.

The former case can be simply replaced by a reference to widget NID
itself.  The only place doing the latter is STAC/IDT codec driver for
the powermap handling.  But, the code doesn't need to check the action
field at all -- the function jack_update_power() is called either with
a specific pin or with NULL.  So the check of jack->action can be
removed completely there, too.

      ALSA: hda - verify pin:converter connection on unsol event for HSW and VLV · b4f75aea
      由 Mengdong Lin 提交于 
      This patch will verify the pin's coverter selection for an active stream
when an unsol event reports this pin becomes available again after a display
mode change or hot-plug event.

For Haswell+ and Valleyview: display mode change or hot-plug can change the
transcoder:port connection and make all the involved audio pins share the 1st
converter. So the stream using 1st convertor will flow to multiple pins
but active streams using other converters will fail. This workaround
is to assure the pin selects the right conveter and an assigned converter is
not shared by other unused pins.
