aa31704fd8 ALSA: hda/ca0132: Add PCI region2 iomap for SBZ
This patch adds iomapping for the region2 section of memory on the SBZ.
This memory region is used in later patches for setting inputs and
outputs. If the mapping fails, the quirk is changed back to QUIRK_NONE
to avoid attempts to write to uninitialized memory.

It also adds a new exit sequence to unmap the iomem for the SBZ.

63177afc98 ALSA: hda/ca0132: Add pincfg for SBZ + R3Di, add fp hp auto-detect
This patch adds an unsolicited response tag for the front headphone
panel which uses the same hp_callback as the rear headphone detection.

This patch also adds pincfgs for the R3Di and SBZ which were taken from
the Windows driver. The pins are also defined in the function
ca0132_config. Both the R3Di and SBZ are also given a max out channel
value of 6 to handle 5.1 surround sound in later patches.

8a19bceef6 ALSA: hda/ca0132: R3Di and SBZ quirk entires + alt firmware loading
This patch adds PCI quirk ID's for the Sound Blaster Z and Recon3Di.
Only the currently tested ID's have been added.

This patch also adds the ability to load alternative firmwares for each
card, the firmwares can be obtained from within the Windows driver.
The Recon3Di uses "ctefx-r3di.bin" and the Sound Blaster Z uses
"ctefx-sbz.bin". If the alternative firmware for the given quirk is not
found, the original ctefx.bin will be used. This has been confirmed to
work for both the R3Di and the SBZ.

This patch also makes the character array *dirstr a const.

8e142e9e62 ALSA: hda/ca0132: fix build failure when a local macro is defined
DECLARE_TLV_DB_SCALE (alias of SNDRV_CTL_TLVD_DECLARE_DB_SCALE) is used but
tlv.h is not included. This causes build failure when local macro is
defined by comment-out.

This commit fixes the bug. At the same time, the alias macro is replaced
with a destination macro added at a commit 46e860f768 ("ALSA: rename
TLV-related macros so that they're friendly to user applications")

f4a414aa6e ALSA: hda - Enforce CONFIG_SND_DYNAMIC_MINORS for HDMI/DP codec
The DP-MST support requires more PCM streams than usual, hence
CONFIG_SND_DYNAMIC_MINORS is almost mandatory.  Currently the driver
just warns and continues even if streams are missing, but it doesn't
seem to enough convince users to switch to the modern setup.

This patch adds the enforced selection of CONFIG_SND_DYNAMIC_MINORS
from CONFIG_SND_HDA_CODEC_HDMI for covering that.

8a7d6003df ALSA: hda - Skip jack and others for non-existing PCM streams
When CONFIG_SND_DYNAMIC_MINORS isn't set, there are only limited
number of devices available, and HD-audio, especially with HDMI/DP
codec, will fail to create more than two devices.

The driver warns about the lack of such devices and skips the PCM
device creations, but the HDMI driver still tries to create the
corresponding JACK, SPDIF and ELD controls even for the non-existing
PCM substreams.  This results in confusion on user-space, and even may
break the operation.

Similarly, Intel HDMI/DP codec builds the ELD notification from i915
graphics driver, and this may be broken if a notification is sent for
the non-existing PCM stream.

This patch adds the check of the existence of the assigned PCM
substream in the both scenarios above, and skips the further operation
if the PCM substream is not assigned.

69fa6f19b9 ALSA: hda: Hardening for potential Spectre v1
As recently Smatch suggested, one place in HD-audio hwdep ioctl codes
may expand the array directly from the user-space value with
speculation:
  sound/pci/hda/hda_local.h:467 get_wcaps() warn: potential spectre issue 'codec->wcaps'

As get_wcaps() itself is a fairly frequently called inline function,
and there is only one single call with a user-space value, we replace
only the latter one to open-code locally with array_index_nospec()
hardening in this patch.

[ More notes:
  according to Kailang, the chip is 10ec:0235 bonding for ALC233b,
  which is equivalent with ALC255.  It's only used for Lenovo.
  The chip needs no alc_process_coef_fw() for headset unlike ALC255. ]

There are two front mics on this machine, if we don't adjust the

pulseaudio can't handle this situation.

After applying this FIXUP, they will have different mixer name,
then pulseaudio can handle them correctly.

3ce0d5aa26 ALSA: hda/realtek - set PINCFG_HEADSET_MIC to parse_flags
Otherwise, the pin will be regarded as microphone, and the jack name
is "Mic Phantom", it is always on in the pulseaudio even nothing is
plugged into the jack. So the UI is confusing to users since the
microphone always shows up in the UI even there is no microphone
plugged.

After adding this flag, the jack name is "Headset Mic Phantom", then
the pulseaudio can handle its detection correctly.

e02d37bf55 sound updates for 4.17-rc1
This became a large update.  The changes are scattered widely,
 and majority of them are attributed to ASoC componentization.
 The gitk output made me dizzy, but it's slightly better than
 London tube.
 
 OK, below are some highlights:
 
 - Continued hardening works in ALSA PCM core; most of the
   existing syzkaller reports should have been covered.
 
 - USB-audio got the initial USB Audio Class 3 support, as well
   as UAC2 jack detection support and more DSD-device support.
 
 - ASoC componentization: finally each individual driver was
   converted to components framework, which is more future-proof
   for further works.  Most of conversations were systematic.
 
 - Lots of fixes for Intel Baytrail / Cherrytrail devices with
   Realtek codecs, typically tablets and small PCs.
 
 - Fixes / cleanups for Samsung Odroid systems
 
 - Cleanups in Freescale SSI driver
 
 - New ASoC drivers:
   * AKM AK4458 and AK5558 codecs
   * A few AMD based machine drivers
   * Intel Kabylake machine drivers
   * Maxim MAX9759 codec
   * Motorola CPCAP codec
   * Socionext Uniphier SoCs
   * TI PCM1789 and TDA7419 codecs

a8d7bde23e ALSA: hda - Force polling mode on CFL for fixing codec communication
We've observed too long probe time with Coffee Lake (CFL) machines,
and the likely cause is some communication problem between the
HD-audio controller and the codec chips.  While the controller expects
an IRQ wakeup for each codec response, it seems sometimes missing, and
it takes one second for the controller driver to time out and read the
response in the polling mode.

Although we aren't sure about the real culprit yet, in this patch, we
put a workaround by forcing the polling mode as default for CFL
machines; the polling mode itself isn't too heavy, and much better
than other workarounds initially suggested (e.g. disabling
power-save), at least.

e40bdb03d3 ALSA: hda/realtek - Always immediately update mute LED with pin VREF
Some HP laptops have a mute mute LED controlled by a pin VREF.  The
Realtek codec driver updates the VREF via vmaster hook by calling
snd_hda_set_pin_ctl_cache().

This works fine as long as the driver is running in a normal mode.
However, when the VREF change happens during the codec being in
runtime PM suspend, the regmap access will skip and postpone the
actual register change.  This ends up with the unchanged LED status
until the next runtime PM resume even if you change the Master mute
switch.  (Interestingly, the machine keeps the LED status even after
the codec goes into D3 -- but it's another story.)

For improving this usability, let the driver temporarily powering up /
down only during the pin VREF change.  This can be achieved easily by
wrapping the call with snd_hda_power_up_pm() / *_down_pm().

07f4f97d7b vga_switcheroo: Use device link for HDA controller
Back in 2013, runtime PM for GPUs with integrated HDA controller was
introduced with commits 0d69704ae3 ("gpu/vga_switcheroo: add driver
control power feature. (v3)") and 246efa4a07 ("snd/hda: add runtime
suspend/resume on optimus support (v4)").

Briefly, the idea was that the HDA controller is forced on and off in
unison with the GPU.

The original code is mostly still in place even though it was never a
100% perfect solution:  E.g. on access to the HDA controller, the GPU
is powered up via vga_switcheroo_runtime_resume_hdmi_audio() but there
are no provisions to keep it resumed until access to the HDA controller
has ceased:  The GPU autosuspends after 5 seconds, rendering the HDA
controller inaccessible.

Additionally, a kludge is required when hda_intel.c probes:  It has to
check whether the GPU is powered down (check_hdmi_disabled()) and defer
probing if so.

However in the meantime (in v4.10) the driver core has gained a feature
called device links which promises to solve such issues in a clean way:
It allows us to declare a dependency from the HDA controller (consumer)
to the GPU (supplier).  The PM core then automagically ensures that the
GPU is runtime resumed as long as the HDA controller's ->probe hook is
executed and whenever the HDA controller is accessed.

By default, the HDA controller has a dependency on its parent, a PCIe
Root Port.  Adding a device link creates another dependency on its
sibling:

                            PCIe Root Port
                             ^          ^
                             |          |
                             |          |
                            HDA  ===>  GPU

The device link is not only used for runtime PM, it also guarantees that
on system sleep, the HDA controller suspends before the GPU and resumes
after the GPU, and on system shutdown the HDA controller's ->shutdown
hook is executed before the one of the GPU.  It is a complete solution.

Using this functionality is as simple as calling device_link_add(),
which results in a dmesg entry like this:

        pci 0000:01:00.1: Linked as a consumer to 0000:01:00.0

The code for the GPU-governed audio power management can thus be removed
(except where it's still needed for legacy manual power control).

The device link is added in a PCI quirk rather than in hda_intel.c.
It is therefore legal for the GPU to runtime suspend to D3cold even if
the HDA controller is not bound to a driver or if CONFIG_SND_HDA_INTEL
is not enabled, for accesses to the HDA controller will cause the GPU to
wake up regardless if they're occurring outside of hda_intel.c (think
config space readout via sysfs).

Contrary to the previous implementation, the HDA controller's power
state is now self-governed, rather than GPU-governed, whereas the GPU's
power state is no longer fully self-governed.  (The HDA controller needs
to runtime suspend before the GPU can.)

It is thus crucial that runtime PM is always activated on the HDA
controller even if CONFIG_SND_HDA_POWER_SAVE_DEFAULT is set to 0 (which
is the default), lest the GPU stays awake.  This is achieved by setting
the auto_runtime_pm flag on every codec and the AZX_DCAPS_PM_RUNTIME
flag on the HDA controller.

A side effect is that power consumption might be reduced if the GPU is
in use but the HDA controller is not, because the HDA controller is now
allowed to go to D3hot.  Before, it was forced to stay in D0 as long as
the GPU was in use.  (There is no reduction in power consumption on my
Nvidia GK107, but there might be on other chips.)

The code paths for legacy manual power control are adjusted such that
runtime PM is disabled during power off, thereby preventing the PM core
from resuming the HDA controller.

Note that the device link is not only added on vga_switcheroo capable
systems, but for *any* GPU with integrated HDA controller.  The idea is
that the HDA controller streams audio via connectors located on the GPU,
so the GPU needs to be on for the HDA controller to do anything useful.

This commit implicitly fixes an unbalanced runtime PM ref upon unbind of
hda_intel.c:  On ->probe, a runtime PM ref was previously released under
the condition "azx_has_pm_runtime(chip) || hda->use_vga_switcheroo", but
on ->remove a runtime PM ref was only acquired under the first of those
conditions.  Thus, binding and unbinding the driver twice on a
vga_switcheroo capable system caused the runtime PM refcount to drop
below zero.  The issue is resolved because the AZX_DCAPS_PM_RUNTIME flag
is now always set if use_vga_switcheroo is true.

40088dc4e1 ALSA: hda - Revert power_save option default value
With the commit 1ba8f9d308 ("ALSA: hda: Add a power_save
blacklist"), we changed the default value of power_save option to -1
for processing the power-save blacklist.
Unfortunately, this seems breaking user-space applications that
actually read the power_save parameter value via sysfs and judge /
adjust the power-saving status.  They see the value -1 as if the
power-save is turned off, although the actual value is taken from
CONFIG_SND_HDA_POWER_SAVE_DEFAULT and it can be a positive.

So, overall, passing -1 there was no good idea.  Let's partially
revert it -- at least for power_save option default value is restored
again to CONFIG_SND_HDA_POWER_SAVE_DEFAULT.  Meanwhile, in this patch,
we keep the blacklist behavior and make is adjustable via the new
option, pm_blacklist.

  since the platform has only a headphone jack without speaker, the

71db96ddfa ALSA: hda - Fix pincfg at resume on Lenovo T470 dock
We've added a quirk to enable the recent Lenovo dock support, where it
overwrites the pin configs of NID 0x17 and 19, not only updating the

that the pin configs are occasionally cleared when the machine goes to

so this won't be applied any longer.

On some boards setting power_save to a non 0 value leads to clicking /

figure out how to avoid these sounds, but that is not always feasible.

This commit adds a blacklist for devices where powersaving is known to
cause problems and disables it on these devices.

Note I tried to put this blacklist in userspace first:
https://github.com/systemd/systemd/pull/8128

But the systemd maintainers rightfully pointed out that it would be
impossible to then later remove entries once we actually find a way to
make power-saving work on listed boards without issues. Having this list
in the kernel will allow removal of the blacklist entry in the same commit
which fixes the clicks / plops.

The blacklist only applies to the default power_save module-option value,
if a user explicitly sets the module-option then the blacklist is not
used.

ALC256 has its own quirk to override the shutup call, and it contains
the COEF update for pulling down the headset jack control.  Currently,
the COEF update is called after clearing the headphone pin, and this
seems triggering a stall of the codec communication, and results in a
long delay over a second at suspend.

A quick resolution is to swap the calls: at first with the COEF
update, then clear the headphone pin.
