HDSPM driver contains a code issuing zero-division potentially in
system sample rate ctl code. This patch fixes it by not processing
a zero or invalid rate value as a divisor, as well as excluding the
invalid value to be passed via the given ctl element.

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.

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.

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

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

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

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()

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.

The original commit disabled the aamixer path due to the noise

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.

When monitor is connected, find a proper PCM for the monitor.
When monitor is disconnected, unbind the PCM from the pin.
The binding policy (use Intel platform as example) is:

of the pin.
2. If step 1 fails, try to bind pin to the backup PCMs. For example,
on Intel platform, if DP MST is enabled, 5 PCMs will be created.
PCM 3, PCM 7, PCM 8 are supposed to be used by device entry 0 of

driver might go into the mixed state doing both probe and remove when
the module gets unloaded during the probe work. This eventually
triggers an Oops, unsurprisingly.
For avoiding this race, we just need to flush the pending probe work

Currently HD-audio driver on Intel Skylake or Broxteon gives an error
message when binding with i915 audio component fails. However, this
isn't any serious error on a system without Intel graphics. Indeed
there are such systems, where a third-party codec (e.g. Creative) is
put on the mobo while using other discrete GPU (e.g. Nvidia).
Printing a kernel "error" message is overreaction in such a case.
This patch downgrades the print level for that message. For systems
that mandate the i915 binding (e.g. Haswell or Broadwell HDMI/DP),
another kernel error message is shown in addition to make clear what

We've had quite busy weeks in this cycle. Looking at ALSA core, the
significant changes are a few fixes wrt timer and sequencer ioctls
that have been revealed by fuzzer recently. Other than that, ASoC
core got a few updates about DAI link handling, but these are rather
straightforward refactoring.
In drivers scene, ASoC received quite lots of new drivers in addition
to bunch of updates for still ongoing Intel Skylake support and
topology API. HD-audio gained a new HDMI/DP hotplug notification via
component. FireWire got a pile of code refactoring/updates with
SCS.1x driver integration.
More highlights are shown below.
[NOTE: this contains also many commits for DRM. This is due to the
pull of drm stable branch into sound tree, as the base of i915 audio
component work for HD-audio. The highlights below don't contain
these DRM changes, as these are supposed to be pulled via drm tree in
anyway sooner or later.]
Core
- Handful fixes to harden ALSA timer and sequencer ioctls against
races reported by syzkaller fuzzer
- Irq description string can be unique to each card; only for
HD-audio for now
ASoC
- Conversion of the array of DAI links to a list for supporting
dynamically adding and removing DAI links
- Topology API enhancements to make everything more component based
and being able to specify PCM links via topology
- Some more fixes for the topology code, though it is still not final
and ready for enabling in production; we really need to get to the
point where that can be done
- A pile of changes for Intel SkyLake drivers which hopefully deliver
some useful initial functionality for systems with this chipset,
though there is more work still to come
- Lots of new features and cleanups for the Renesas drivers
- ANC support for WM5110
- New drivers: Imagination Technologies IPs, Atmel class D speaker,
Cirrus CS47L24 and WM1831, Dialog DA7128, Realtek RT5659 and
RT56156, Rockchip RK3036, TI PC3168A, and AMD ACP
- Rename PCM1792a driver to be generic pcm179x
HD-Audio
- Use audio component for i915 HDMI/DP hotplug handling
- On-demand binding with i915 driver
- bdl_pos_adj parameter adjustment for Baytrail controllers
- Enable power_save_node for CX20722; this shouldn't lead to
regression, hopefully
- Kabylake HDMI/DP codec support
- Quirks for Lenovo E50-80, Dell Latitude E-series, and other Dell
machines
- A few code refactoring
FireWire
- Lots of code cleanup and refactoring
- Integrate the support of SCS.1x devices into snd-oxfw driver;
snd-scs1x driver is obsoleted
USB-audio
- Fix possible NULL dereference at disconnection
- A regression fix for Native Instruments devices

Merge tag 'sound-4.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"We've had quite busy weeks in this cycle. Looking at ALSA core, the
significant changes are a few fixes wrt timer and sequencer ioctls
that have been revealed by fuzzer recently. Other than that, ASoC
core got a few updates about DAI link handling, but these are rather
straightforward refactoring.
In drivers scene, ASoC received quite lots of new drivers in addition
to bunch of updates for still ongoing Intel Skylake support and
topology API. HD-audio gained a new HDMI/DP hotplug notification via
component. FireWire got a pile of code refactoring/updates with
SCS.1x driver integration.
More highlights are shown below.
[ NOTE: this contains also many commits for DRM. This is due to the
pull of drm stable branch into sound tree, as the base of i915 audio
component work for HD-audio. The highlights below don't contain
these DRM changes, as these are supposed to be pulled via drm tree
in anyway sooner or later. ]
Core:
- Handful fixes to harden ALSA timer and sequencer ioctls against
races reported by syzkaller fuzzer
- Irq description string can be unique to each card; only for
HD-audio for now
ASoC:
- Conversion of the array of DAI links to a list for supporting
dynamically adding and removing DAI links
- Topology API enhancements to make everything more component based
and being able to specify PCM links via topology
- Some more fixes for the topology code, though it is still not final
and ready for enabling in production; we really need to get to the
point where that can be done
- A pile of changes for Intel SkyLake drivers which hopefully deliver
some useful initial functionality for systems with this chipset,
though there is more work still to come
- Lots of new features and cleanups for the Renesas drivers
- ANC support for WM5110
- New drivers: Imagination Technologies IPs, Atmel class D speaker,
Cirrus CS47L24 and WM1831, Dialog DA7128, Realtek RT5659 and
RT56156, Rockchip RK3036, TI PC3168A, and AMD ACP
- Rename PCM1792a driver to be generic pcm179x
HD-Audio:
- Use audio component for i915 HDMI/DP hotplug handling
- On-demand binding with i915 driver
- bdl_pos_adj parameter adjustment for Baytrail controllers
- Enable power_save_node for CX20722; this shouldn't lead to
regression, hopefully
- Kabylake HDMI/DP codec support
- Quirks for Lenovo E50-80, Dell Latitude E-series, and other Dell
machines
- A few code refactoring
FireWire:
- Lots of code cleanup and refactoring
- Integrate the support of SCS.1x devices into snd-oxfw driver;
snd-scs1x driver is obsoleted
USB-audio:
- Fix possible NULL dereference at disconnection
- A regression fix for Native Instruments devices
Misc:
- A few code cleanups of fm801 driver"

This is because HDA is still in D0 state after freeze() call and
pci_pm_freeze/pci_pm_freeze_noirq() don't set D3 hot in pci_bus driver.
It seems bios still access HDA when system enter into freeze state,
HDA will receive codec response interrupt immediately after thaw() call.
Because of this unexpected interrupt, HDA enter into a abnormal

Lenovo Thinkpads with Realtek codecs may still have some loud
crackling noises at reboot/shutdown even though a few previous fixes
have been applied. It's because the previous fix (disabling the
default shutup callback) takes effect only at transition of the codec
power state. Meanwhile, at reboot or shutdown, we don't take down the
codec power as default, thus it triggers the same problem unless the
codec is powered down casually by runtime PM.
This patch tries to address the issue. It gives two things:
- implement the separate reboot_notify hook to struct alc_spec, and
call it optionally if defined.
- turn off the codec to D3 for Thinkpad models via this new callback

another existing alc_fixup_disable_aamix(). It resulted in a good

Intel Atom processors seem to have a problem at recording when
bdl_pos_adj is set to an odd value. When a value like 1 is used, it
may drop the samples unexpectedly. Actually, for the old Atoms, we
used to set AZX_DRIVER_SCH type, and this assigns 32 as default.
Meanwhile the newer chips, Baytrail and Braswell, are set as
AZX_DRIVER_PCH, and the lower default value, 1, is assigned.
This patch changes the default values for these chipsets to a safer
default, 32, again. Since changing the driver type (AZX_DRIVER_XXX)
leads to the rename of the driver string, it would result in a
possible regression. So, we can't change the type. Instead, in this
patch, manual (ugly) PCI ID checks are added on top.
A drawback by this increase is the slight increase of the latency, but
it's a sub-ms order in normal situations, so mostly negligible.

Since we have a new audio component ops to fetch the current ELD and
state now, we can reduce the usage of unsol event of HDMI/DP pins.
The unsol event isn't only unreliable, but it also needs the power
up/down of the codec and link at each time, which is a significant
power and time loss.
In this patch, the jack creation and unsol/jack event handling are
modified to use the audio component for the dedicated Intel chips.
The jack handling got slightly more codes than a simple usage of
hda_jack layer since we need to deal directly with snd_jack object;
the hda_jack layer is basically designed for the pin sense read and
unsol events, both of which aren't used any longer in our case.

Due to the recent change, HDA controller driver for Intel PCH tries to
bind i915 audio component always at the probe time no matter whether
HDMI/DP codec is found. This is, however, superflulous for old
chipsets (e.g. on IVB) where they don't have always the HDMI/DP codecs
but often have only a discrete GPU instead.
For the newer chipsets, we need already the i915 binding from the
beginning due to power well control. Meanwhile, for older chipsets
where we don't need power well, we don't need the i915 binding at the
controller level.
This patch removes again the i915 binding in the HDA controller driver
for old Intel PCHs, but adds the binding in HDMI/DP codec driver
instead. This allows still the use of the direct notification from
the graphics driver while we can avoid the unnecessary load of i915
driver for machines only with another GPU.

Lenovo Thinkpad T440s suffers from constant background noises, and it
seems to be a generic hardware issue on this model:
https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/T440s-speaker-noise/td-p/1339883
As the noise comes from the analog loopback path, disabling the path
is the easy workaround.
Also, the machine gives significant cracking noises at PM suspend. A
workaround found by trial-and-error is to disable the shutup callback
currently used for ALC269-variant.
This patch addresses these noise issues by introducing a new fixup
chain. Although the same workaround might be applicable to other
Thinkpad models, it's applied only to T440s (17aa:220c) in this patch,
so far, just to be safe (you chicken!). As a compromise, a new model
option string "tp440" is provided now, though, so that owners of other
Thinkpad models can test it more easily.

snd-hda-intel driver tries to bind with i915 audio component always
when AZX_DCAPS_I915_POWERWELL is set in the driver caps. This was
mostly OK in the past, as the flag was applied only to a limited set
of devices, namely, Haswell and Broadwell. On these machines, i915
graphics is almost mandatory as long as HDMI/DP is concerned.
Recently the application of i915 binding was widened to more Intel
chips. On these chips, the chance of a kernel without i915 graphics
is much higher, and such user would hit an error like:
snd_hda_intel 0000:00:1b.0: failed to add i915 component master (-19)
Although the error itself is harmless, it's certainly superfluous even
to try binding with i915, if we already know that there isn't any.
This patch fixes it by simply defining AZX_DCAPS_I915_POWERWELL as 0
in the case without i915. Then all codes referring to this flag will
be optimized out by the compiler.

The recent commit [6603249dcd: ALSA: hda - Enable audio component

Intel PCHs. But many boards are without HDMI/DP, and they actually
don't need i915 binding, and yet the driver has a check of i915
binding and complains like
Haswell must be built with CONFIG_SND_HDA_I915
This error is false-positive, and it should be put only for HSW/BDW,
instead of all devices that may be bound with i915.
This patch fixes the condition to check, as well as rephrasing the
message specific to HSW/BDW HDMI/DP.

Many codecs, typically found on Realtek codecs, have the analog
loopback path merged to the secondary input of the middle of the
output paths. Currently, we don't offer the dynamic switching in such
configuration but let each loopback path mute by itself.
This should work well in theory, but in reality, we often see that
such a dead loopback path causes some background noises even if all
the elements get muted. Such a problem has been fixed by adding the
quirk accordingly to disable aamix, and it's the right fix, per se.
The only problem is that it's not so trivial to achieve it; user needs
to pass a hint string via patch module option or sysfs.
This patch gives a bit improvement on the situation: it adds "Loopback
Mixing" control element for such codecs like other codecs (e.g. IDT or
VIA codecs) with the individual loopback paths. User can turn on/off
the loopback path simply via a mixer app.
For keeping the compatibility, the loopback is still enabled on these
codecs. But user can try to turn it off if experiencing a suspicious
background or click noise on the fly, then build a static fixup later
once after the problem is addressed.
Other than the addition of the loopback enable/disablement control,
there should be no changes.

is noise with the notification sound. We have 3 SKUs for each of
the models, all of them have this problem.
So far, this problem is only specific to these two thinkpad models,
we did not find this problem on the old thinkpad models with the
codec alc293 or alc292.
A workaround for this problem is disabling the aamix.

On the internal mic of the Packard Bell DOTS, one channel
has an inverted signal. Add a quirk to fix this up.

In BXT-P A0, HD-Audio DMA requests is later than expected,
and makes an audio stream sensitive to system latencies when
24/32 bits are playing.
Adjusting threshold of DMA fifo to force the DMA request
sooner to improve latency tolerance at the expense of power.

rme96 driver needs to reset DAC depending on the sample rate, and this
results in resetting to the max volume suddenly. It's because of the
missing call of snd_rme96_apply_dac_volume().
However, calling this function right after the DAC reset still may not
work, and we need some delay before this call. Since the DAC reset
and the procedure after that are performed in the spinlock, we delay
the DAC volume restore at the end after the spinlock.

As i915 graphics driver provides the notification via audio component,
not only the currently implemented HSW+ and VLV+ platforms but also
all other PCH-based platforms (e.g. Cougar Point, Panther Point, etc)
can use this infrastructure. It'll improve the reliability and the
power consumption significantly, especially once when we implement the
ELD notification via component. As a preliminary, this patch enables
the usage of audio component for all PCH platforms.
The HDA controller just needs to set AZX_DCAPS_I915_POWERWELL flag
appropriately. The name of the flag is a bit confusing, but this
actually works even on the chips without the powerwell but accesses
only the other component ops.
In the HDMI/DP codec driver side, we just need to register/unregister
the notifier for such chips. This can be identified by checking the
audio_component field in the assigned hdac_bus.
One caveat is that PCH for Haswell and Broadwell must not be bound
with i915 audio component, as there are dedicated HD-audio HDMI
controllers on these platforms. Ditto for Poulsbo and Oaktrail as
they use gma500 graphics, not i915.

This is a preliminary patch for the later change to support ELD/jack
handling with i915 audio component. This splits the ELD update code
from hdmi_present_sense() so that it can be called from other places.
Just a code refactoring, no functional change.

Instead of doing in each caller side, snd_hdmi_parse_eld() does
zero-clear of the parsed data by itself. This is safer and simplifies
the upcoming code changes.

The ELD notification can be received asynchronously from the graphics
side, and this may happen just at the moment the sound driver is
processing the suspend or the resume, and it would confuse the whole
procedure. Since the ELD and connection states are updated in anyway
at the end of the resume, we can skip it when received during PM
process.
