ALSA: hda: Disable runtime resume at shutdown

Although we modified the codec shutdown callback to perform
runtime-suspend, it's still not fully effective, as this may be
resumed again at any time later.

For fixing such an unwanted resume, this patch replaces
pm_runtime_suspend() with pm_runtime_force_suspend(), and call
pm_runtime_disable() afterward.  It assures to keep the device
suspended.

Also for code simplification, we apply the code unconditionally; when
it's been already suspended, nothing would happen by calls of
snd_pcm_suspend_all() and pm_runtime_force_suspend(), just proceed to
pm_runtime_disable().

ALSA: usb-audio: Fix regression on Sony WALKMAN NW-A45 DAC

We've got a regression report for USB-audio with Sony WALKMAN NW-A45
DAC device where no sound is audible on recent kernel.  The bisection
resulted in the code change wrt endpoint management, and the further
debug session revealed that it was caused by the order of the USB
audio interface.  In the earlier code, we always set up the USB
interface at first before other setups, but it was changed to be done
at the last for UAC2/3, which is more standard way, while keeping the
old way for UAC1.  OTOH, this device seems requiring the setup of the
interface at first just like UAC1.

This patch works around the regression by applying the interface setup
specifically for the WALKMAN at the beginning of the endpoint setup
procedure.  This change is written straightforwardly to be easily
backported in old kernels.  A further cleanup to move the workaround
into a generic quirk section will follow in a later patch.

ALSA: hda/realtek: Workaround for conflicting SSID on ASUS ROG Strix G17

ASUS ROG Strix G17 has the very same PCI and codec SSID (1043:103f) as
ASUS TX300, and unfortunately, the existing quirk for TX300 is broken
on ASUS ROG.  Actually the device works without the quirk, so we'll
need to clear the quirk before applying for this device.
Since ASUS ROG has a different codec (ALC294 - while TX300 has
ALC282), this patch adds a workaround for the device, just clearing
the codec->fixup_id by checking the codec vendor_id.

It's a bit ugly to add such a workaround there, but it seems to be the
simplest way.

approach for 5.14, and that was the commit above.

Now, since the codec drivers go runtime-suspend at shutdown for 5.15,
we can revert the change and make sure that the full runtime-suspend
is performed at shutdown of HD-audio controller again.  This patch
essentially reverts the commit above to restore the behavior.

ALSA: hda: Suspend codec at shutdown

So far we have a few workarounds at shutdown for each codec,
e.g. turning off the display power and setting the codec to D3.
But all those are basically a part of the suspend procedure.
Moreover, the streams are still active after that call, hence it might
hit the update on the codec that has been already put to D3.

In this patch, instead of calling each reboot_notify callback, simply
put the codec into the runtime-suspended state after the manual
suspend of all PCM streams.  It makes the code and the behavior more
consistent.

The reboot_notify callback is no longer used after this patch, and
will be cleaned up later.

ALSA: pcm: Add SNDRV_PCM_INFO_EXPLICIT_SYNC flag

ALSA PCM core has an optimized way to communicate with user-space for
its control and status data via mmap on the supported architectures
like x86.  Depending on the situation, however, we'd rather want to
enforce user-space notifying the applptr or hwptr change explicitly
via ioctl.  For example, the upcoming non-contig and non-coherent
buffer handling would need an explicit sync, and this needs to catch
the applptr and hwptr changes.  Also, ASoC SOF driver will have the
SPIB support that has the similar requirement for the explicit control
of the applptr and hwptr.

This patch adds the new PCM hardware info flag,
SNDRV_PCM_INFO_EXPLICIT_SYNC.  When this flag is set, PCM core
disables both the control and the status mmap, which enforces
user-space to update via SYNC_PTR ioctl.  In that way, drivers can
catch the applptr and hwptr update and apply the sync operation if
needed.

ALSA: memalloc: Count continuous pages in vmalloc buffer handler

This is an enhancement for the SG-style page handling in vmalloc
buffer handler to calculate the continuous pages.
When snd_sgbuf_get_chunk_size() is called for a vmalloc buffer,
currently we return only the size that fits into a single page.
However, this API call is rather supposed for obtaining the continuous
pages and most of vmalloc or noncontig buffers do have lots of
continuous pages indeed.  So, in this patch, the callback now
calculates the possibly continuous pages up to the given size limit.

Note that the end address in the function is calculated from the last
byte, hence it's one byte shorter.  This is because ofs + size can be
above the actual buffer size boundary.

Until now, this feature isn't really used, but it'll become useful in
a later patch that adds the non-contiguous buffer type that shares the
same callback function as vmalloc.

ALSA: hda/cs8409: Dont disable I2C clock between consecutive accesses

Only disable I2C clock 25 ms after not being used.

The current implementation enables and disables the I2C clock for each
I2C transaction. Each enable/disable call requires two verb transactions.
This means each I2C transaction requires a total of four verb transactions
to enable and disable the clock.
However, if there are multiple consecutive I2C transactions, it is not
necessary to enable and disable the clock each time, instead it is more
efficient to enable the clock for the first transaction, and disable it
after the final transaction, which would improve performance.
This is achieved by using a timeout which disables the clock if no request
to enable the clock has occurred for 25 ms.

ALSA: oxfw: fix functioal regression for silence in Apogee Duet FireWire

OXFW 971 has no function to use the value in syt field of received
isochronous packet for playback timing generation. In kernel prepatch for
v5.14, ALSA OXFW driver got change to send NO_INFO value in the field
instead of actual timing value. The change brings Apogee Duet FireWire to

As long as I investigate, _any_ value in the syt field takes the device to
generate sound. It's reasonable to think that the device just ignores data
blocks in packet with NO_INFO value in its syt field for audio data
processing.

ALSA: pcm: Check mmap capability of runtime dma buffer at first

Currently we check only the substream->dma_buffer as the preset of the
buffer configuration for verifying the availability of mmap.  But a
few drivers rather set up the buffer in the own way without the
standard buffer preallocation using substream->dma_buffer, and they
miss the proper checks.  (Now it's working more or less fine as most
of them are running only on x86).

Actually, they may set up the runtime dma_buffer (referred via
snd_pcm_get_dma_buf()) at the open callback, though.  That is, this
could have been used as the primary source.

This patch changes the hw_support_mmap() function to check the runtime
dma buffer at first.  It's usually NULL with the standard buffer
preallocation, and in that case, we continue checking
substream->dma_buffer as fallback.

ALSA: harmony: Drop superfluous address setup

Harmony driver never uses CONTINUOUS buffer type any longer, hence the
code setting the address is superfluous.  Moreover, the recent change
in the ALSA core already covered the missing address field; it's
already set up.  So let's drop the superfluous line, which includes

ALSA: pcm: Fix mmap breakage without explicit buffer setup

The recent fix c4824ae7db41 ("ALSA: pcm: Fix mmap capability check")
restricts the mmap capability only to the drivers that properly set up
the buffers, but it caused a regression for a few drivers that manage
the buffer on its own way.

For those with UNKNOWN buffer type (i.e. the uninitialized / unused
substream->dma_buffer), just assume that the driver handles the mmap
properly and blindly trust the hardware info bit.

ALSA: memalloc: Fix mmap of SG-buffer with WC pages

The code refactoring to move the WC page handling into the common

the driver is using the SG-buffer, which isn't covered by the patch.

This patch adds the mmap workaround for WC pages to SG-buffer

returning an error after setting the pgprot, so it won't work in all

ASoC: Fixes for v5.14

Quite a lot of fixes here, the biggest set being for the cs42l42 driver
which is reasonably old but has seen a sudden uptick in activity.
There's also some fixes for correctly referencing PCM buffer addresses
and the removal of some driver-local bodges that had been done for the
lack of prefix handling in DAPM which were broken by the core handling
that as expected.

ASoC: cs42l42: Fix mono playback

I2S always has two LRCLK phases and both CH1 and CH2 of the RX
must be enabled (corresponding to the low and high phases of LRCLK.)
The selection of the valid data channels is done by setting the DAC
CHA_SEL and CHB_SEL. CHA_SEL is always the first (left) channel,
CHB_SEL depends on the number of active channels.

Previously for mono ASP CH2 was not enabled, the result was playing
mono data would not produce any audio output.

ASoC: cs42l42: Constrain sample rate to prevent illegal SCLK

rates less than this would produce SCLK below the minimum when using
a normal I2S frame. A constraint must be applied to prevent this.

The constraint is not applied if the machine driver sets SCLK, to
allow setups where the host generates additional bits per LRCLK
phase to increase the SCLK frequency. In these cases the machine

ALSA: pcm: Allow exact buffer preallocation

A few drivers want to have rather the exact buffer preallocation at
the driver probe time and keep using it for the whole operations
without allowing dynamic buffer allocation.  For satisfying the
demands, this patch extends the managed buffer allocation API
slightly.

Namely, when 0 is passed to max argument of the allocation helper
functions snd_pcm_set_managed_buffer*(), it treats as if the fixed
size allocation of the given size.  If the pre-allocation fails in
this mode, the function returns now -ENOMEM.  Otherwise, i.e. max
argument is non-zero, the function never returns -ENOMEM but tries to
fall back to the smaller chunks and allows the dynamic allocation
later -- which is still the default behavior until now.

For more intuitive use, also two new helpers are added for handling
the fixed size buffer allocation, too: snd_pcm_set_fixed_buffer() and
snd_pcm_set_fixed_buffer_all().

ASoC: cs42l42: Remove duplicate control for WNF filter frequency

The driver was defining two ALSA controls that both change the same
register field for the wind noise filter corner frequency. The filter
response has two corners, at different frequencies, and the duplicate

either of the frequencies.

However, having two controls changing the same field can be problematic
and it is unnecessary. Both frequencies are related to each other so
setting one implies exactly what the other would be.

Removing a control affects user-side code, but there is currently no
known use of the removed control so it would be best to remove it now
before it becomes a problem.

addition completes, and this may lead to a use-after-free or an Oops,
even though the access to both lists are protected via mutex.

The simple workaround for this race is to change the access order for
the disconnection, namely, dest list, then src list.  This assures
that the connection has been established when disconnecting, and also
the concurrent deletion can be avoided.

ASoC: SOF: Intel: hda-ipc: fix reply size checking

Checking that two values don't have common bits makes no sense,
strict equality is meant.

ASoC: SOF: Intel: Kconfig: fix SoundWire dependencies

The previous Kconfig cleanup added simplifications but also introduced
a new one by moving a boolean to a tristate. This leads to randconfig
problems.

This patch moves the select operations in the SOUNDWIRE_LINK_BASELINE
option. The INTEL_SOUNDWIRE config remains a tristate for backwards
compatibility with older configurations but is essentially an on/off
switch.
