67f3754b51 ALSA: pcxhr: Fix missing mutex unlock
The commit [9bef72bdb2: ALSA: pcxhr: Use nonatomic PCM ops]
converted to non-atomic PCM ops, but shamelessly with an unbalanced
mutex locking, which leads to the hangup easily.  Fix it.

de3df8a986 ALSA: hda - Keep powering up ADCs on Cirrus codecs
Although one weird behavior about the input path (inconsistent D0/D3
switch) on Cirrus CS420x codecs was fixed in the previous commit,
there is still an issue on some Mac machines: the capture stream
stalls when switching the ADCs on the fly.  More badly, this keeps
stuck until the next reboot.

The dynamic ADC switching is already a bit fragile and assuming
optimistically that the chip accepts the frequent power changes.  On
Cirrus codecs, this doesn't seem applicable.

As a quick workaround, we pin down the ADCs to keep up in D0 when
spec->dyn_adc_switch is set.  In this way, the ADCs are kept up only
for the system that were confirmed to be broken.

afecb146d8 ALSA: hda/realtek - Add ALC3234 headset mode for Optiplex 9020m
The Optiplex 9020m with Haswell-DT processor needs a quirk for the
headset jack at the front of the machine to be able to use microphones.

A quirk for this model was originally added in 3127899, but c77900e
removed it in favour of a more generic version.

Unfortunately, pin configurations can changed based on firmware/BIOS
versions, and the generic version doesn't have any effect on newer
versions of the machine/firmware anymore.

50fd4987c4 ALSA: hda - Don't trust the reported actual power state
We've got a regression report that the recording on Mac with a cirrus
codec doesn't work any longer.  This turned out to be the missing
power up to D0 by power_save_node enablement.

After analyzing the traces, we found out that the culprit is that the
codec advertises the "actual" power state of a few nodes to be D0
while the "target" power state is D3.  This inconsistency is usually
OK, as it implies the power transition.  But in the case of cirrus
codec, this seems to be stuck to D3 while it's not actually D0.

This patch addresses the issue by checking the power state difference
more strictly.  It sends the power-state change verb unless both the
target and the actual power states show the given value.

We may introduce yet another flag indicating the possible broken
hardware power state, but it's anyway safer to set the proper power
state even in a transition (at least it's harmless as long as the
target state is same).  So this simpler change was applied now.

a19c921fca ALSA: lx646es: Fix possible uninitialized variable reference
lx_pipe_state() checks the return value from lx_message_send_atomic()
and breaks the loop only when it's a negative value.  However,
lx_message_send_atomic() may return a positive error code (as the
return code from the hardware), and then lx_pipe_state() tries to
compare the uninitialized current_state variable.

Fix this behavior by checking the positive non-zero error code as
well.

c44da62b55 ALSA: hda - Fix inconsistent monitor_present state until repoll
While the previous commit fixed the missing monitor_present flag
update, it may be still in an inconsistent state while the driver
repolls: the flag itself is updated, but the eld_valid flag and the
contents don't follow until the repoll finishes (and may be repeated
for a few times).

The basic problem is that pin_eld->monitor_present is updated in the
caller side.  This should have been updated only in update_eld().  So,
the proper fix is to avoid accessing pin_eld but only spec->temp_eld.

023d8218ec ALSA: hda - Fix regression of monitor_present flag in eld proc file
The commit [bd48128539: ALSA: hda - Fix forgotten HDMI
monitor_present update] covered the missing update of monitor_present
flag, but this caused a regression for devices without the i915 eld
notifier.  Since the old code supposed that pin_eld->monitor_present
was updated by the caller side, the hdmi_present_sense_via_verbs()
doesn't update the temporary eld->monitor_present but only
pin_eld->monitor_present, which is now overridden in update_eld().

The fix is to update pin_eld->monitor_present as well before calling
update_eld().

Note that this may still leave monitor_present flag in an inconsistent
state when the driver repolls, but this is at least the old behavior.
More proper fix will follow in the later patch.

c68ae33e7f ACPI / utils: Rename acpi_dev_present()
acpi_dev_present() was originally named after pci_dev_present()
to signify the similarity of the two functions.

However Rafael J. Wysocki pointed out that the exported function
acpi_dev_present() is easily confused with the non-exported
acpi_device_is_present(). Additionally in ACPI parlance the term
"present" usually refers to the "device is present" bit returned
by the _STA control method, yet acpi_dev_present() merely checks
presence in the namespace. It does not invoke _STA at all, let
alone check the "device is present" bit.

As suggested by Rafael, rename the function to acpi_dev_found()
and adjust all existing call sites.

4926c80465 ALSA: intel8x0: Drop superfluous VM checks
intel8x0 driver has the inside_vm check for skipping a buggy hardware
workaround in the PCM pointer callback in the commit [228cf79376:
ALSA: intel8x0: Improve performance in virtual environment].  This was
originally applied to all devices on known VMs, but the code was
switched to use the PCI  ID matching for applying to only known
devices (KVM and Parallels), in order to avoid applying wrongly to
VT-d and other such cases, in the commit [7fb4f392bd: ALSA:
intel8x0: improve virtual environment detection].

Meanwhile, the original VM check was kept even after switching to the
PCI ID matching.  It was partly because we weren't 100% sure whether
we had covered all well, and partly because this would help
identifying the issue once when a user of another VM hit the same
problem or a regression.  Currently the VM check is used only for
showing the kernel message that the VM-optimization isn't applied, and
the VM check itself doesn't change the actual driver behavior at all.

Despite the relatively safe driver behavior, the code caught attention
of developers badly and brought many confusion / misunderstanding.
Since we've got neither regression nor enhancement report for other
VMs for five years long, it's likely safe to drop this superfluous VM
check now.

The module option is still kept, so if a user still needs to adjust,
it can be applied as was.

44fde3b89b ALSA: hda - Update chmap tlv to report sink's capability
The existing TLV callback implementation copies all of the
cea_channel_speaker_allocation map table to the TLV container
irrespective of what is reported by sink. This is of little use
to the userspace application.

With this patch, it parses the spk_alloc block as queried from
the ELD, and copies only the corresponding mapping channel
allocation entries from the cea channel speaker allocation table.
Thus the user can parse the TLV container to identify sink's
capability and set the channel map accordingly.

It shouldn't impact the behavior in AMD chipset, as this makes
use of already parsed spk alloc block to calculate the channel
map.

Intel IronLake and ValleyView platforms have different HDMI widget pin

For adapting this mapping, pass the codec object instead of the bus
object to snd_hdac_sync_audio_rate() and snd_hdac_acomp_get_eld() so
that they can check the codec ID and calculate the mapping properly.

The changes in the HDMI codec driver side will follow in the later

a686632fd9 ALSA: hda - Split out Intel-specific codes from patch_generic_hdmi()
We have too many Intel-specific codes in patch_hdmi_generic() despite
its function name.  And this makes it difficult to adjust per chipset,
e.g. for allowing the audio notifier on an old chipset, one would need
to add an explicit if() check.

This patch attempts some code refactoring and cleanups in this regard;
the Intel-specific codes are moved out of patch_generic_hdmi() into
the new functions, patch_i915_hsw_hdmi() and patch_i915_byt_hdmi(),
depending on the chipset.  The other old Intel chipsets keep using
patch_generic_hdmi() without Intel hacks.  The existing
patch_generic_hdmi() is also split to a few components so that they
can be called from the Intel codec parsers.

There are still many is_haswell*() and is_valleyview*() macro usages
in the code.  They will be cleaned up later.  For the time being, only
the entry are concerned.

Along with this change, the i915_bound flag and the on-demand i915
component binding have been removed as a cleanup, since there is no
user at this moment.  This will be added back later once when Cougar
Point and else start using the i915 eld notifier.

c64c1437af ALSA: hda - Fix missing ELD update at unplugging
i915 get_eld ops may return an error when no encoder is connected, and
currently we regard the error as fatal and skip the whole ELD
handling.  This ended up with the missing ELD update at unplugging.

This patch fixes the issue by treating the error as the unplugged
state, instead of skipping the rest.

7169701ad3 ALSA: hda - Workaround for unbalanced i915 power refcount by concurrent probe
The recent addition of on-demand i915 audio component binding in the
codec driver seems leading to the unbalanced i915 power refcount,
according to Intel CI tests.  Typically, it gets a kernel WARNING
like:
  WARNING: CPU: 3 PID: 173 at sound/hda/hdac_i915.c:91 snd_hdac_display_power+0xf1/0x110 [snd_hda_core]()
  Call Trace:
   [<ffffffff813fef15>] dump_stack+0x67/0x92
   [<ffffffff81078a21>] warn_slowpath_common+0x81/0xc0
   [<ffffffff81078b15>] warn_slowpath_null+0x15/0x20
   [<ffffffffa00f77e1>] snd_hdac_display_power+0xf1/0x110 [snd_hda_core]
   [<ffffffffa015039d>] azx_intel_link_power+0xd/0x10 [snd_hda_intel]
   [<ffffffffa011e32a>] azx_link_power+0x1a/0x30 [snd_hda_codec]
   [<ffffffffa00f21f9>] snd_hdac_link_power+0x29/0x40 [snd_hda_core]
   [<ffffffffa01192a6>] hda_codec_runtime_suspend+0x76/0xa0 [snd_hda_codec]
   .....

The scenario is like below:
- HD-audio driver and i915 driver are probed concurrently at the
  (almost) same time; HDA bus tries to bind with i915, but it fails
  because i915 initialization is still being processed.
- Later on, HD-audio probes the HDMI codec, where it again tries to
  bind with i915.  At this time, it succeeds.
- At finishing the probe of HDA, it decreases the refcount as if it
  were already bound at the bus probe, since the component is bound
  now.  This triggers a kernel WARNING due to the unbalance.

As a workaround, in this patch, we just disable the on-demand i915
component binding in the codec driver.  This essentially reverts back
to the state of 4.4 kernel.

We know that this is no real solution, but it's a minimalistic simple
change that can be applied to 4.5.x kernel as stable.

93a9ff1517 ALSA: hda - Fix spurious kernel WARNING on Baytrail HDMI
snd_hdac_sync_audio_rate() call is mandatory only for HSW and later
models, but we call the function unconditionally blindly assuming that
the function doesn't do anything harmful.  But since recently, the
function checks the validity of the passed pin NID, and eventually
spews the warning if an unexpected pin is passed.  This is seen on old
chips like Baytrail.

The fix is to limit the call of this function again only for the chips
with the proper binding.  This can be identified by the same flag as
the eld notifier.

691be973c0 ALSA: hda - Really restrict i915 notifier to HSW+
The commit [b62232d429: ALSA: hda - Limit i915 HDMI binding only for
HSW and later] tried to limit the usage of i915 audio notifier to the
recent Intel models and switch to the old method on pre-Haswell
models.  However, it assumed that the i915 component binding hasn't
been done on such models, and the assumption was wrong: namely,
Baytrail had already the i915 component binding due to powerwell
control.  Thus, the workaround wasn't applied to Baytrail.

For fixing this properly, this patch introduces a new flag indicating
the usage of audio notifier and codec_has_acomp() refers to this flag
instead of checking the existence of audio component.

222bde0388 ALSA: hda - Fix mutex deadlock at HDMI/DP hotplug
The recent change in HD-audio HDMI/DP codec driver for allowing the
dynamic PCM binding introduced a new spec->pcm_mutex.  One of the
protected area by this mutex is hdmi_present_sense().  As reported by
Intel CI tests, unfortunately, the new mutex causes a deadlock when
the hotplug/unplug is triggered during the codec is in runtime
suspend.  The buggy code path is like the following:

  hdmi_unsol_event() -> ...
    -> hdmi_present_sense()
==>     ** here taking pcm_mutex
      -> hdmi_present_sense_via_verbs()
        -> snd_hda_power_up_pm() -> ... (runtime resume calls)
          -> generic_hdmi_resume()
            -> hdmi_present_sense()
==>           ** here taking pcm_mutex again!

As we can see here, the problem is that the mutex is taken before
snd_hda_power_up_pm() call that triggers the runtime resume.  That is,
the obvious solution is to move the power up/down call outside the
mutex; it is exactly what this patch provides.

The patch also clarifies why this bug wasn't caught beforehand.  We
used to have the i915 audio component for hotplug for all Intel chips,
and in that code path, there is no power up required but the
information is taken directly from the graphics side.  However, we
recently switched back to the old method for some old Intel chips due
to regressions, and now the deadlock issue is surfaced.

b62232d429 ALSA: hda - Limit i915 HDMI binding only for HSW and later
It turned out that the pre-HSW Intel chips are incompatible with the
naive assumption we had -- the fixed mapping between the port and the
HD-audio widget.  This may result in the bad access, as captured by
the recent patch to add a WARN_ON() for the port mapping check.

As a quick workaround, disable the i915 audio component binding for
all pre-Haswell models.

1f7c665896 ALSA: hda - Fix unconditional GPIO toggle via automute
Cirrus HD-audio driver may adjust GPIO pins for EAPD dynamically
depending on the jack plug state.  This works fine for the auto-mute
mode where the speaker gets muted upon the HP jack plug.   OTOH, when
the auto-mute mode is off, this turns off the EAPD unexpectedly
depending on the jack state, which results in the silent speaker
output.

This patch fixes the silent speaker output issue by setting GPIO bits
constantly when the auto-mute mode is off.

4f8e4f3537 ALSA: hda - Don't handle ELD notify from invalid port
The current Intel HDMI codec driver supports only three fixed ports
from port B to port D.  However, i915 driver may assign a DP on other

This patch filters out such invalid events beforehand, so that the
kernel won't be too grumbling.

30ff5957c3 ALSA: hda - Autosuspend controller after probe even if codecs are already suspended
azx_probe_continue() uses pm_runtime_put_noidle() to drop the rpm
usage_count, which means that if it's the last reference the
autosuspend of the controller won't actually happen. So if the codecs
autosuspend before the azx_probe_continue() drops the last
reference we'll fail to autosuspend the controller. This does happen
in practice, but not every time. As can be seen in [1] the controller
autosuspend attempt fails due to the usage_count when suspending the
codecs. A bit later we see the the contoller usage_count dropping to
zero without further attempts at autosuspend.

Fix the problem by using pm_runtime_put_autosuspend() instead, which
will kick off the autosuspend of the controller even if the codecs
are already asleep. As can be seen in [2] the controller autosuspend
still fails while suspending the codecs, but later on we see another
autosuspend attempt after dropping the usage_count to 0.

I was also a bit worried that there might still be a race between the
controller autosuspend and the rest of the code in azx_probe_continue().
So I also tried replacing the the put_noidle() with put_sync_suspend().
No explosions occurred, so I'm somewhat satisfied that there are no
serious problems in this area.

473f414564 ALSA: hda - Loop interrupt handling until really cleared
Currently the interrupt handler of HD-audio driver assumes that no irq
update is needed while processing the irq.  But in reality, it has
been confirmed that the HW irq is issued even during the irq
handling.  Since we clear the irq status at the beginning, process the
interrupt, then exits from the handler, the lately issued interrupt is
left untouched without being properly processed.

This patch changes the interrupt handler code to loop over the
check-and-process.  The handler tries repeatedly as long as the IRQ
status are turned on, and either stream or CORB/RIRB is handled.

For checking the stream handling, snd_hdac_bus_handle_stream_irq()
returns a value indicating the stream indices bits.  Other than that,
the change is only in the irq handler itself.

fe0d128c57 ALSA: jack: Allow building the jack layer without input device
Since the recent integration of kctl jack and input jack layers, we
can basically build the jack layer even without input devices.  That
is, the jack layer itself can be built with conditional to enable the
input device support or not, while the users may enable always
CONFIG_SND_JACK unconditionally.

For achieving it, this patch changes the following:
- A new Kconfig, CONFIG_SND_JACK_INPUT_DEV, was introduced to indicate
  whether the jack layer supports the input device,
- A few items in snd_jack struct and relevant codes are conditionally
  built upon CONFIG_SND_JACK_INPUT_DEV,
- The users of CONFIG_SND_JACK drop the messy dependency on
  CONFIG_INPUT.

This change also automagically fixes a potential bug in HD-audio
driver Arnd reported, where the NULL or uninitialized jack instance is
dereferenced.

7e31a01594 ALSA: hda - Apply clock gate workaround to Skylake, too
Some Skylake machines show the codec probe errors in certain
situations, e.g. HP Z240 desktop fails to probe the onboard Realtek
codec at reloading the snd-hda-intel module like:
  snd_hda_intel 0000:00:1f.3: spurious response 0x200:0x2, last cmd=0x000000
  snd_hda_intel 0000:00:1f.3: azx_get_response timeout, switching to polling mode: lastcmd=0x000f0000
  snd_hda_intel 0000:00:1f.3: No response from codec, disabling MSI: last cmd=0x000f0000
  snd_hda_intel 0000:00:1f.3: Codec #0 probe error; disabling it...
  hdaudio hdaudioC0D2: no AFG or MFG node found
  snd_hda_intel 0000:00:1f.3: no codecs initialized

Also, HP G470 G3 suffers from the similar problem, as reported in
bugzilla below.  On this machine, the codec probe error appears even
at a fresh boot.

As Libin suggested, the same workaround used for Broxton in the commit
[6639484dda: ALSA: hda - disable dynamic clock gating on Broxton
 before reset] can be applied for Skylake in order to fix this problem.
The Intel HW team also confirmed that this is needed for SKL.

This patch makes the workaround applied to both SKL and BXT
platforms.  The referred macros are moved and one superfluous macro
(IS_BROXTON()) is another one (IS_BXT()) as well.

The commit [991f86d7ae: ALSA: hda - Flush the pending probe work at
remove] introduced the sync of async probe work at remove for fixing
the race.  However, this may lead to another hangup when the module
removal is performed quickly before starting the probe work, because
it issues flush_work() and it's blocked forever.

The workaround is to use cancel_work_sync() instead of flush_work()
there.

2ebab40eb7 ALSA: hda - Fix bad dereference of jack object
The hda_jack_tbl entries are managed by snd_array for allowing
multiple jacks.  It's good per se, but the problem is that struct
hda_jack_callback keeps the hda_jack_tbl pointer.  Since snd_array
doesn't preserve each pointer at resizing the array, we can't keep the
original pointer but have to deduce the pointer at each time via
snd_array_entry() instead.  Actually, this resulted in the deference
to the wrong pointer on codecs that have many pins such as CS4208.

This patch replaces the pointer to the NID value as the search key.
As an unexpected good side effect, this even simplifies the code, as
only NID is needed in most cases.

6c361d10e0 Revert "ALSA: hda - Fix noise on Gigabyte Z170X mobo"
This reverts commit 0c25ad8040.

The original commit disabled the aamixer path due to the noise
problem, but it turned out that some mobo with the same PCI SSID
doesn't suffer from the issue, and the disabled function (analog
loopback) is still demanded by users.

Since the recent commit [e7fdd52779: ALSA: hda - Implement loopback
control switch for Realtek and other codecs], we have the dynamic
mixer switch to enable/disable the aamix path, and we don't have to
disable the path statically any longer.  So, let's revert the
disablement, so that only the user suffering from the noise problem
can turn off the aamix on the fly.

6590faaba4 ALSA: hda - hdmi begin to support dynamic PCM assignment
Begin to support dynamic PCM assignment to pin in
hdmi audio driver.

This means PCM will not be statically bound with pin.
When there is a monitor connected, the corresponding pin
will try to find a proper PCM to bind. When the monitor
is disconnected, the corresponding pin will unbind
the PCM. This helps to reduce the PCM number when there
are many pins (device entries in DP MST mode) and only
a few of them work at the same time.

This patch adds the pcm member in struct hdmi_spec_per_pin.
When PCM is dynamically bound to the pin, the member pcm
will pointer to the corresponding pcm_rec[] in hdmi_spec,
which means the hda_pcm is bound to the pin.

3ec622f409 ALSA: hda - Add new GPU codec ID 0x10de0083 to snd-hda
Vendor ID 0x10de0083 is used by a yet-to-be-named GPU chip.

This chip also has the 2-ch audio swapping bug, so patch_nvhdmi is
appropriate here.
