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.

Just a minor cleanup; instead of passing an array, pass the assigned
bdl_pos_adj option value directory in struct azx. Also split the code
to get the default bdl_pos_adj value for the change that will follow
after this.

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.

The recent commit [6603249dcd: 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.

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.

We've had many reports that some Creative sound cards with CA0132
don't work well. Some reported that it starts working after reloading
the module, while some reported it starts working when a 32bit kernel
is used. All these facts seem implying that the chip fails to
communicate when the buffer is located in 64bit address.
This patch addresses these issues by just adding AZX_DCAPS_NO_64BIT
flag to the corresponding PCI entries. I casually had a chance to
test an SB Recon3D board, and indeed this seems helping.
Although this hasn't been tested on all Creative devices, it's safer
to assume that this restriction applies to the rest of them, too. So
the flag is applied to all Creative entries.

The active attribute in struct vga_switcheroo_client denotes whether
the outputs are currently switched to this client. The attribute is
only meaningful for vga clients. It is never used for audio clients.
The function vga_switcheroo_register_audio_client() misuses this
attribute to store whether the audio device is fully initialized.
Most likely there was a misunderstanding about the meaning of
"active" when this was added.
Comment from Takashi's review:
"Not really. The full initialization of audio was meant that the audio
is active indeed. Admittedly, though, the active flag for each audio
client doesn't play any role because the audio always follows the gfx
state changes, and the value passed there doesn't reflect the actual
state due to the later change. So, I agree with the removal of the
flag itself -- or let the audio active flag following the
corresponding gfx flag. The latter will make the proc output more
consistent while the former is certainly more reduction of code."
Set the active attribute to false for audio clients. Remove the
active parameter from vga_switcheroo_register_audio_client() and
its sole caller, hda_intel.c:register_vga_switcheroo().
vga_switcheroo_register_audio_client() was introduced by 3e9e63dbd3
("vga_switcheroo: Add the support for audio clients"). Its use in
hda_intel.c was introduced by a82d51ed24 ("ALSA: hda - Support
VGA-switcheroo").
v1.1: The changes above imply that in find_active_client() the call
to client_is_vga() is now superfluous. Drop it.

PM ops could be triggered before HDA is done initializing
and cause PM to set HDA controller to D3Hot. This can result
in "CORB reset timeout#2, CORBRP = 65535" and "no codecs
initialized". Additionally, PM ops can be triggered before
azx_probe_continue finishes (async probe). This can result
in a NULL deref kernel crash.
To fix this, avoid PM ops if !chip->running.

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).
(Otherwise it would only have been called for Haswell and Broadwell,
which both do not need it, so this probably was not the author's
intention.)

The previous patch tried to continue the probe if i915 binding fails.
For for simplicity reason, we haven't implemented abort even for
controller chips that are dedicated for HDMI/DP on HSW and BDW.
However, Mengdong suggested that this can be dangerous; BIOS may
disable gfx power well although the PCI entry for HD-audio is left,
and this may result in the unexpected behavior, kernel errors, etc.
For avoiding this situation, abort the probe at i915 binding failure
only for HSW/BDW chips selectively. For other chips, it still
continues.

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.

- The i915 audio component is moved to core bus and dynamically allocated.
- A static pointer hdac_acomp is used to help bind/unbind callbacks to get
this component, because the sound card's private_data is used by the azx
chip pointer, which is a legacy structure. It could be removed if private
_data changes to some core structure which can be extended to find the
bus.
- snd_hdac_get_display_clk() is added to get the display core clock for
HSW/BDW.
- haswell_set_bclk() is moved to hda_intel.c because it needs to write the
controller registers EM4/EM5, and only legacy HD-A needs it for HSW/BDW.
- Move definition of HSW/BDW-specific registers EM4/EM5 to hda_register.h
and rename them to HSW_EM4/HSW_EM5, because other HD-A controllers have
different layout for the extended mode registers.

In SKL, HDMI/DP codec and PCH HD Audio Controller are in different power wells,
so it's necessary to reset display audio codecs when power well on, otherwise
display audio codecs will disappear when resume from low power state.
Reset steps when power on:
enable codec wakeup -> azx_init_chip() -> disable codec wakeup
The callback for codec wakeup enable/disable is in drivers/gpu/drm/i915/.

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.

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.

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 the final bit of runtime PM cleanup: instead of manual
notification of the power up/down of the codec via hda_bus pm_notify
ops, use the standard runtime PM feature.
The child codec device will kick off the runtime PM of the parent
(PCI) device upon suspend/resume automatically. For managing whether
the link can be really turned off, we use the bit flags
bus->codec_powered instead of the earlier bus->power_keep_link_on.
flag. Each codec driver is responsible to set/clear the bit flag, and
the controller device can be turned off only when all these bits are
cleared.

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.)
Along with this change, the pointer argument of azx_bus_create() is
dropped as well.

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.

Merge tag 'v3.18-rc7' into for-next
... for allowing more cleanups of hda_intel.c driver-caps where both
upstream and for-next contain the changes.
User can pass snoop option to enable/disable the snoop behavior, but
currently azx_check_snoop_available() always turns it off for some
devices. For better debuggability, change the parameter as bint, and
allow user to enable/disable forcibly the snoop when specified via the
module option.

Add a new driver_caps bit, AZX_DCAPS_SNOOP_OFF, to set the snoop off
as default. This new bit is used for the checks in
azx_check_snoop_available(). Most of case-switches are replaced with
the new dcaps in each entry.
While working on it, for avoiding to spend more bits, combine three
bits AZX_DCAPS_SNOOP_SCH, AZX_DCAPS_SNOOP_ATI and
AZX_DCAPS_SNOOP_NVIDIA bits into a flat type of two bits. This
reduces the bits usages, and assign AZX_DCAPS_OFF to this empty bit
now.

A number of radeon cards have a HW limitation causing them to be
unable to generate the full 64-bit of address bits for MSIs. This
breaks MSIs on some platforms such as POWER machines.
We used to have a powerpc specific quirk to address that on a
single card, but this doesn't scale very well, this is better
put under control of the drivers who know precisely what a given
HW revision can do.
We now have a generic quirk in the PCI code. We should set it
appropriately for all radeon's from the audio driver.

AMD/ATI HDMI controller chip models, we already have a filter to lower
to 32bit DMA, but the rest are supposed to be working with 64bit
although the hardware doesn't really work with 63bit but only with 40
or 48bit DMA. In this patch, we take 40bit DMA for safety for the
AMD/ATI controllers as the graphics drivers does.

The functions kfree() and release_firmware() test whether their argument
is NULL and then return immediately. Thus the test around the call
is not needed.
This issue was detected by using the Coccinelle software.

CMI8888 shows the stuttering playback when the snooping is disabled
on the audio buffer. Meanwhile, we've got reports that CORB/RIRB
doesn't work in the snooped mode. So, as a compromise, disable the
snoop only for CORB/RIRB and enable the snoop for the stream buffers.
The resultant patch became a bit ugly, unfortunately, but we still can
live with it.

ASUS Phoebus with CMI8888 HD-audio chip (PCI id 13f6:5011) doesn't
work with HD-audio driver as is because of some weird nature. For
making DMA properly working, we need to disable MSI. The position
report buffer doesn't work, thus we need to force reading LPIB
instead. And yet, the codec CORB/RIRB communication gives errors
unless we disable the snooping (caching).
In this patch, all these workarounds are added as a quirk for the
device. The HD-audio *codec* chip needs yet another workaround, but
it'll be provided in the succeeding patch.

Since init_failed flag was moved to struct hda_intel, its access in
the commit [4da63c6f: ALSA: hda - Fix broken PM due to incomplete
i915 initialization] is also replaced with hda->init_failed
appropriately.
When the initialization of Intel HDMI controller fails due to missing
i915 kernel symbols (e.g. HD-audio is built in while i915 is module),
the driver discontinues the probe. However, since the probe was done
asynchronously, the driver object still remains, thus the relevant PM
ops are still called at suspend/resume. This results in the bad access
to the incomplete audio card object, eventually leads to Oops or stall
at PM.
This patch adds the missing checks of chip->init_failed flag at each
PM callback in order to fix the problem above.

We got a regression report for 3.15.x kernels, and this turned out to
be triggered by the fix for stream assignment order. On reporter's
machine with Intel controller (8086:1e20) + VIA VT1802 codec, the
first playback slot can't work with speaker outputs.
But the original commit was actually a fix for AMD controllers where
no proper GCAP value is returned, we shouldn't revert the whole
commit. Instead, in this patch, a new flag is introduced to determine
the stream assignment order, and follow the old behavior for Intel
controllers.

For HSW/BDW display HD-A controller, hda_set_bclk() is defined to set BCLK
by programming the M/N values as per the core display clock (CDCLK) queried from
i915 display driver.
And the audio driver will also set BCLK in azx_first_init() since the display
driver can turn off the shared power in boot phase if only eDP is connected
and M/N values will be lost and must be reprogrammed.
