      ALSA: hda - Set SKL+ hda controller power at freeze() and thaw() · 3e6db33a
      由 Xiong Zhang 提交于 
      It takes three minutes to enter into hibernation on some OEM SKL
machines and we see many codec spurious response after thaw() opertion.
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
state and slow down the system enter into hibernation.

In this patch, we put HDA into D3 hot state in azx_freeze_noirq() and
put HDA into D0 state in azx_thaw_noirq().

V2: Only apply this fix to SKL+
    Fix compile error when CONFIG_PM_SLEEP isn't defined

      ALSA: hda - Move audio component accesses to hdac_i915.c · e2dc7d7d
      由 Takashi Iwai 提交于 
      A couple of i915_audio_component ops have been added and accessed
directly from patch_hdmi.c.  Ideally all these should be factored out
into hdac_i915.c.

This patch does it, adds two new helper functions for setting N/CTS
and fetching ELD bytes.  One bonus is that the hackish widget vs port
mapping is also moved to hdac_i915.c, so that it can be fixed /
enhanced more cleanly.

      ALSA: hda - Use component ops for i915 HDMI/DP audio jack handling · 788d441a
      由 Takashi Iwai 提交于 
      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.

      ALSA: hda - Fix superfluous HDMI jack repoll · 9a5e5234
      由 Takashi Iwai 提交于 
      The recent commit [e90247f9: ALSA: hda - Split ELD update code
from hdmi_present_sense()] rewrote the HDMI jack handling code, but a
slight behavior change sneaked in unexpectedly.  When the jack isn't
connected, it tries repoll unnecessarily.

This patch addresses the flaw, to the right behavior as before.

      ALSA: hda - Allow i915 binding later in codec driver · 55913110
      由 Takashi Iwai 提交于 
      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.

      ALSA: hda - Fix noise problems on Thinkpad T440s · 9a811230
      由 Takashi Iwai 提交于 
      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.

      ALSA: hda - Don't try to bind i915 unless CONFIG_SND_HDA_I915 is set · fbaf9f9f
      由 Takashi Iwai 提交于 
      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.

      ALSA: hda - Less grumbling about lack of i915 binding · 6ee8eeb4
      由 Takashi Iwai 提交于 
      The recent commit [6603249d: ALSA: hda - Enable audio component
for old Intel PCH devices] enabled the i915 binding for HDMI/DP on old
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.

      ALSA: hda - Implement loopback control switch for Realtek and other codecs · e7fdd527
      由 Takashi Iwai 提交于 
      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.
