At the same time they happens the white noise by login screen and headphone;
for fixing them together, I only can add these IDs to FIXUP function ALC292_FIXUP_DISABLE_AAMIX,
then try to solve such the similar issues.

In the commit [fa4f18b4f4: 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.

The widget power-saving code tries to turn up/down the power of each
widget in the I/O paths that are modified at each jack plug/unplug.
The recent report revealed that the power activation leaves some
widgets unpowered after plugging. This is because
snd_hda_activate_path() turns on path->active flag at the end of the
function while the path power management is done before that. Then
it's regarded as if nothing is active, and the driver turns off the
power.
The fix is simply to set the flag at the beginning of the function,
before trying to power up.

Alienware 15 has CA0132 codec for its onboard sound, but the pin
config and mapping seem quite different from other Creative boards.
This patch corrects them, at least, for providing the right headphone
and mic jack notification, as well as removing the non-existing SPDIF
pins.
Even with this fix, not all stuff works perfectly yet, mainly because
of the badly written ca0132 driver code -- it has too many implicit
assumptions of pin configs and maps. Nevertheless, this is a small
good step forward.

When the controller is powered up but the HDMI codec is powered down
on Skylake, the power well is turned off. When the codec is then
powered up again, we need to poke the codec a little extra to make
sure it wakes up. Otherwise we'll get sad "no response from codec"
messages and broken audio.
This also changes azx_runtime_resume to actually call
snd_hdac_set_codec_wakeup for Skylake (before STATETS read).

which both do not need it, so this probably was not the author's

Fujitsu Lifebook E780 sets the sequence number 0x0f to only only of
the two headphones, thus the driver tries to assign another as the
line-out, and this results in the inconsistent mapping between the
created jack ctl and the actual I/O. Due to this, PulseAudio doesn't
handle it properly and gets the silent output.
The fix is to ignore the non-HP sequencer checks.

Yet another regression by the transition to regmap cache; for better

Conexant codecs, and this was forgotten in the new hda core code.
Since the bits 4-7 are unused for the amp registers (as we follow the
syntax of AMP_GET verb), the bit 4 is now used to indicate the fake
mute. For setting this flag, snd_hda_codec_amp_update() becomes a
function from a simple macro. The bonus is that it gained a proper

Currently snd-hda-intel driver aborts the probing of Intel HD-audio
controller with i915 power well management when binding with i915
driver via hda_i915_init() fails. This is no big problem for Haswell
and Broadwell where the HD-audio controllers are dedicated to
HDMI/DP, thus i915 link is mandatory. However, Skylake, Baytrail and
Braswell have only one controller and both HDMI/DP and analog codecs
share the same bus. Thus, even if HDMI/DP isn't usable, we should
keep the controller working for other codecs.
For fixing this, this patch simply allows continuing the probing even
if hda_i915_init() call fails. This may leave stale sound components
for HDMI/DP devices that are unbound with graphics. We could abort
the probing selectively, but from the code simplicity POV, it's better
to continue in all cases.

- snd_hdac_get_display_clk() is added to get the display core clock for

- haswell_set_bclk() is moved to hda_intel.c because it needs to write the

This patch can improve power saving for Intel platforms on which only the
display audio codec is in the shared i915 power well:
- Add a flag "need_i915_power" to indicate whether the controller needs the
i915 power well.
- The driver will always request the i915 power when probing the controller
and codecs if AZX_DCAPS_I915_POWERWELL is set (either the controller or a
codec needs this power).
- If the controller needs the i915 power, the power will be held after probe
until the controller is runtime suspended or S3. If the controller doesn't
need the power, the power will be released the after probe, and a codec
that needs the power can request/release the power via bus link_power ops.
Background:
- For Haswell/Broadwell, which has a separate HD-A controller for display audio,
both the controller and the display codec are in the i915 power well.
- For Baytrail/Braswell, the display and analog audio share the same HDA
controller and link, and only the display codec is in the i915 power well.
- For Skylake, the display and analog audio share the same HDA controller but
use separate links. Only the display codec is in the i915 power well. And in
legacy mode we take the two links as one. So it can follow Baytrail/Braswell.

HD-Audio and ASoC jack. This allows non root userspace to read jack status
and act on it.
This patch adds a new API called snd_jack_add_new_kctl(), which will create
a kcontrol, add it to the card, and also attach it to the jack kctl list.
This patch also initialises the jack kctl list after jack is newed, and
reports kctl status when jack insertion/removal events occur.
snd_jack_new() is updated in the following patches to also support creating
phantom jacks and jack kcontrols. We then remove these duplicated features
from HDA jack and have jack kctls handled by core throughout HDA and ASoC.

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.

This patch addes AZX_DCAPS_I915_POWERWELL to BYT (Baytrail).
Like Braswell and Skylake, the HDMI codec on Bytrail is also in the shared
power well with GPU. This power well must be turned on before we reset link
to probe the codec, to avoid communication failure with the codec.
The side effect is that this power is always ON in S0 because the BYT HDMI
codec does not support EPSS or D3ClkStop and so the controller doesn't enter
D3 at runtime, and the HDMI codec and analog codec share a single physical
HD-A link and so we cannot reset the HD-A link freely when we re-enable the
power to use the HDMI codec.
Next step is to test if an AGP reset or double AGP reset on BYT HDMI codec is
okay to bring the HDMI codec back to a functional state after restoring the
power. If okay, we can bind the power on/off with the HDMI codec PM without
interrupting the analog audio.

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...

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.

The amp hash table was used for recording the cached reads of some
capability values like pin caps or amp caps. Now all these are moved
to regmap as well.
One addition to the regmap helper is codec->caps_overwriting flag.
This is set in snd_hdac_override_parm(), and the regmap helper accepts
any register while this flag is set, so that it can overwrite even the
read-only verb like AC_VERB_PARAMETERS. The flag is cleared
immediately in snd_hdac_override_parm(), as it's a once-off flag.
Along with these changes, the no longer needed amp hash and relevant
fields are removed from hda_codec struct now.

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.

This patch adds an infrastructure to support regmap-based verb
accesses. Because o the asymmetric nature of HD-audio verbs,
especially the amp verbs, we need to translate the verbs as a sort of
pseudo registers to be mapped uniquely in regmap.
In this patch, a pseudo register is built from the NID, the
AC_VERB_GET_* and 8bit parameters, i.e. almost in the form to be sent
to HD-audio bus but without codec address field. OTOH, for writing,
the same pseudo register is translated to AC_VERB_SET_* automatically.
The AC_VERB_SET_AMP_* verb is re-encoded from the corresponding
AC_VERB_GET_AMP_* verb and parameter at writing.
Some verbs has a single command for read but multiple for writes. A
write for such a verb is split automatically to multiple verbs.
The patch provides also a few handy helper functions. They are
designed to be accessible even without regmap. When no regmap is set
up (e.g. before the codec device instantiation), the direct hardware
access is used. Also, it tries to avoid the unnecessary power-up.
The power up/down sequence is performed only on demand.
The codec driver needs to call snd_hdac_regmap_exit() and
snd_hdac_regmap_exit() at probe and remove if it wants the regmap
access.
There is one flag added to hdac_device. When the flag lazy_cache is
set, regmap helper ignores a write for a suspended device and returns
as if it was actually written. It reduces the hardware access pretty
much, e.g. when adjusting the mixer volume while in idle. This
assumes that the driver will sync the cache later at resume properly,
so use it carefully.

This patch changes the sysfs files assigned to the codec device on the
bus which were formerly identical with hwdep sysfs files. Now it
shows only a few core parameter, vendor_id, subsystem_id, revision_id,
afg, mfg, vendor_name and chip_name.
In addition, now a widget tree is added to the bus device sysfs
directory for showing the widget topology and attributes. It's just a
flat tree consisting of subdirectories named as the widget NID
including various attributes like widget capability bits. The AFG
(usually NID 0x01) is always found there, and it contains always
amp_in_caps, amp_out_caps and power_caps files. Each of these
attributes show a single value. The rest are the widget nodes
belonging to that AFG. Note that the child node might not start from
0x02 but from another value like 0x0a.
Each child node may contain caps, pin_caps, amp_in_caps, amp_out_caps,
power_caps and connections files. The caps (representing the widget
capability bits) always contain a value. The rest may contain
value(s) if the attribute exists on the node. Only connections file
show multiple values while other attributes have zero or one single
value.

Some pins are used for controlling the LED with the VREF value.
This patch changes the power behavior of such pins to be constantly
up. A new state, pin_fixed, is introduced to nid_path to indicate
that the path contains the fixed pin. This improves also the
readability a bit for other static routes, too.
Then a helper function snd_hda_gen_fix_pin_power() is called from the
codec driver for such fixed pins, and it will create fake paths
containing only these pins with pin_fixed=1 flag.

VIA codecs used to have the own power controls but they were disabled
at transition to the generic parser due to the coding assuming the
fixed routes. Now we get the proper support of equivalently fine
power management in the generic parser, and the old kludges can be
replaced with it. This results in the reduction of lots of dead
codes.
The advanced PM feature is disabled as default like before for keeping
the compatible behavior. It's enabled via "Dynamic Power-Control"
mixer element.

This patch enables the finer power state control of each widget
depending on the jack plug state and streaming state in addition to
the existing power_down_unused power optimization. The new feature is
enabled only when codec->power_mgmt flag is set.
Two new flags, pin_enabled and stream_enabled, are introduced in
nid_path struct for marking the two individual power states: the pin
plug/unplug and DAC/ADC stream, respectively. They can be set
statically in case they are static routes (e.g. some mixer paths),
too.
The power up and down events for each pin are triggered via the
standard hda_jack table. The call order is hard-coded, relying on the
current implementation of jack event chain (a la FILO/stack order).
One point to be dealt carefully is that DAC/ADC cannot be powered
on/off while streaming. They are pinned as long as the stream is
running. For controlling the power of DAC/ADC, a new patch_ops is
added. The generic parser provides the default callback for that.
As of this patch, only IDT/Sigmatel codec driver enables the flag.
The support on other codecs will follow.
An assumption we made in this code is that the widget state (e.g. amp,
pinctl, connections) remains after the widget power transition (not
about FG power transition). This is true for IDT codecs, at least.
But if the widget state is lost at widget power transition, we'd need
to implement additional code to sync the cached amp/verbs for the
specific NID.

The commit [ef403edb75: ALSA: hda - Don't access stereo amps for
mono channel widgets] fixed the handling of mono widgets in general,
but it still misses an exceptional case: namely, a mono mixer widget
taking a single stereo input. In this case, it has stereo volumes
although it's a mono widget, and thus we have to take care of both
left and right input channels, as stated in HD-audio spec ("7.1.3
Widget Interconnection Rules").
This patch covers this missing piece by adding proper checks of stereo
amps in both the generic parser and the proc output codes.

The current HDA generic parser initializes / modifies the amp values
always in stereo, but this seems causing the problem on ALC3229 codec
that has a few mono channel widgets: namely, these mono widgets react
to actions for both channels equally.
In the driver code, we do care the mono channel and create a control
only for the left channel (as defined in HD-audio spec) for such a
node. When the control is updated, only the left channel value is
changed. However, in the resume, the right channel value is also
restored from the initial value we took as stereo, and this overwrites
the left channel value. This ends up being the silent output as the
right channel has been never touched and remains muted.
This patch covers the places where unconditional stereo amp accesses
are done and converts to the conditional accesses.

The commit [63e51fd708: ALSA: hda - Don't take unresponsive D3
transition too serious] introduced a conditional fallback behavior to
the HD-audio controller depending on the flag set. However, it
introduced a silly bug, too, that the flag was evaluated in a reverse
way. This resulted in a regression of HD-audio controller driver
where it can't go to the fallback mode at communication errors.
Unfortunately (or fortunately?) this didn't come up until recently
because the affected code path is an error handling that happens only
on an unstable hardware chip. Most of recent chips work stably, thus
they didn't hit this problem. Now, we've got a regression report with
a VIA chip, and this seems indeed requiring the fallback to the
polling mode, and finally the bug was revealed.
The fix is a oneliner to remove the wrong logical NOT in the check.
(Lesson learned - be careful about double negation.)
The bug should be backported to stable, but the patch won't be
applicable to 3.13 or earlier because of the code splits. The stable
fix patches for earlier kernels will be posted later manually.

This makes the code flow easier -- instead of the controller driver
calling snd_hda_build_pcms() and snd_hda_build_controls() explicitly,
the codec driver itself builds PCMs and controls at probe time. Then
the controller driver only needs to call snd_card_register().
Also, this allows us the full bind/unbind control, too. Even when a
codec driver is bound later, it automatically registers the new PCM
and controls by itself.

Now we have all pieces ready, and put them into places:
- add the hda_pcm refcount to azx_pcm_open() and azx_pcm_close(),

driver remove,
- call the same code also from the hda_codec object free.
Then the codec driver can be unbound more safely now.

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.

snd_hda_build_pcms() does actually three things: let the codec driver
build up hda_pcm list, set the PCM default values, and call the
attach_pcm bus ops for each hda_pcm instance. The former two are
basically independent from the bus implementation, so it'd make the
code a bit more readable.

We leave the pcm field of struct hda_pcm at removal of each device, so
far. This hasn't been a problem since unbinding the codec driver
isn't supposed to happen and another route via snd_hda_codec_reset()
clears all the once. However, for a proper unbind implementation, we
need to care about it.
This patch does the thing above properly:
- Include struct hda_pcm pointer instead of struct hda_pcm_stream
pointers in struct azx_dev. This allows us to point the hda_pcm
object at dev_free callback.
- Introduce to_hda_pcm_stream() macro for better readability.

Now the final bit of runtime PM cleanup: instead of manual
notification of the power up/down of the codec via hda_bus pm_notify

The child codec device will kick off the runtime PM of the parent
(PCI) device upon suspend/resume automatically. For managing whether

We used to pass the power_save option value to hda_bus via a given
pointer. This was needed to refer to the value from the HD-audio core
side. However, after the transition to the runtime PM, this is no
longer needed.
This patch drops the power_save value indirection in hda_bus above,
and let the controller driver reprograms the autosuspend value
explicitly by a new helper, snd_hda_set_power_save(). Without this
call, the HD-audio core doesn't set up the autosuspend and flip the
runtime PM. (User may still be able to set up via sysfs, though.)

Like the previous transition of suspend/resume, now move the
power-save code to the standard runtime PM. As usual for runtime PM,
it's a bit tricky, but this simplified codes a lot in the end.
For keeping the usage compatibility, power_save module option still
controls the whole power-saving behavior on all codecs. The value is
translated to pm_runtime_*_autosuspend() and pm_runtime_allow() /
pm_runtime_forbid() calls.
snd_hda_power_up() and snd_hda_power_down() are translated to
pm_runtime_get_sync() and pm_runtime_put_autosuspend(), respectively.
Since we can do call pm_runtime_get_sync() more reliably, the sync
version is used always and snd_hda_power_up_d3wait() is dropped.
Another slight difference is that snd_hda_power_up()/down() don't call
runtime_pm code during the suspend/resume transition phase. Calling
them there isn't safe unlike our own code, resulted in unexpected
behavior (endless wakeups).
The hda_power_count tracepoint was removed, as it doesn't match well
with the new code.
Last but not least, we need to set ignore_children flag in the parent
dev.power field so that the runtime PM of the controller chip won't
get confused. The notification is still done in the bus pm_notify
callback. We'll get rid of this hack in the later patch.

This patch moves the suspend/resume mechanisms down to each codec
driver level, as we have a proper codec driver bound on the bus now.
Then we get the asynchronous PM gratis without fiddling much in the
driver level.
As a soft-landing transition, implement the common suspend/resume pm
ops for hda_codec_driver and keep the each codec driver intact. Only
the callers of suspend/resume in the controller side (azx_suspend()
and azx_resume()) are removed.
Another involved place is azx_bus_reset() calling the temporary
suspend and resume as a hackish method of bus reset. The HD-audio
core provide a helper function snd_hda_bus_reset() instead.

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.
