[alsa-devel] [PATCH AUTOSEL 5.5 033/542] ALSA: ctl: allow TLV read operation for callback type of element in locked case

[Sasha Levin]

From: Takashi Sakamoto <o-takashi@sakamocchi.jp>

[ Upstream commit d61fe22c2ae42d9fd76c34ef4224064cca4b04b0 ]

A design of ALSA control core allows applications to execute three
operations for TLV feature; read, write and command. Furthermore, it
allows driver developers to process the operations by two ways; allocated
array or callback function. In the former, read operation is just allowed,
thus developers uses the latter when device driver supports variety of
models or the target model is expected to dynamically change information
stored in TLV container.

The core also allows applications to lock any element so that the other
applications can't perform write operation to the element for element
value and TLV information. When the element is locked, write and command
operation for TLV information are prohibited as well as element value.
Any read operation should be allowed in the case.

At present, when an element has callback function for TLV information,
TLV read operation returns EPERM if the element is locked. On the
other hand, the read operation is success when an element has allocated
array for TLV information. In both cases, read operation is success for
element value expectedly.

This commit fixes the bug. This change can be backported to v4.14
kernel or later.

[alsa-devel] [PATCH AUTOSEL 5.5 175/542] ASoC: SOF: Intel: hda: solve MSI issues by merging ipc and stream irq handlers

[Sasha Levin]

From: Bard Liao <yung-chuan.liao@linux.intel.com>

[ Upstream commit 7c11af9fcdc425b80f140a218d4fef9f17734bfc ]

The existing code uses two handlers for a shared edge-based MSI interrupts.
In corner cases, interrupts are lost, leading to IPC timeouts. Those
timeouts do not appear in legacy mode.

This patch merges the two handlers and threads into a single one, and
simplifies the mask/unmask operations by using a single top-level mask
(Global Interrupt Enable). The handler only checks for interrupt
sources using the Global Interrupt Status (GIS) field, and all the
actual work happens in the thread. This also enables us to remove the
use of spin locks. Stream events are prioritized over IPC ones.

This patch was tested with HDaudio and SoundWire platforms, and all
known IPC timeout issues are solved in MSI mode. The
SoundWire-specific patches will be provided in follow-up patches,
where the SoundWire interrupts are handled in the same thread as IPC
and stream interrupts.

[alsa-devel] [PATCH AUTOSEL 5.5 221/542] ALSA: usx2y: Adjust indentation in snd_usX2Y_hwdep_dsp_status

[Sasha Levin]

From: Nathan Chancellor <natechancellor@gmail.com>

[ Upstream commit df4654bd6e42125d9b85ce3a26eaca2935290b98 ]

Clang warns:

../sound/usb/usx2y/usX2Yhwdep.c:122:3: warning: misleading indentation;
statement is not part of the previous 'if' [-Wmisleading-indentation]
        info->version = USX2Y_DRIVER_VERSION;
        ^
../sound/usb/usx2y/usX2Yhwdep.c:120:2: note: previous statement is here
        if (us428->chip_status & USX2Y_STAT_CHIP_INIT)
        ^
1 warning generated.

This warning occurs because there is a space before the tab on this
line. Remove it so that the indentation is consistent with the Linux
kernel coding style and clang no longer warns.

This was introduced before the beginning of git history so no fixes tag.

[alsa-devel] [PATCH AUTOSEL 5.5 283/542] ALSA: hda/realtek - Apply mic mute LED quirk for Dell E7xx laptops, too

[Sasha Levin]

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit 5fab5829674c279839a7408ab30c71c6dfe726b9 ]

Dell E7xx laptops have also mic mute LED that is driven by the
dell-laptop platform driver.  Bind it with the capture control as
already done for other models.

A caveat is that the fixup hook for the mic mute LED has to be applied
at last, otherwise it results in the invalid override of the callback.

[alsa-devel] [PATCH AUTOSEL 5.5 288/542] ASoC: Intel: sof_rt5682: Ignore the speaker amp when there isn't one.

[Sasha Levin]

From: Sam McNally <sammc@chromium.org>

[ Upstream commit d4b74e218a8d0d6cf58e546627ab9d4d4f2645ab ]

Some members of the Google_Hatch family include a rt5682 jack codec, but
no speaker amplifier. This uses the same driver (sof_rt5682) as a
combination of rt5682 jack codec and max98357a speaker amplifier. Within
the sof_rt5682 driver, these cases are not currently distinguishable,
relying on a DMI quirk to decide the configuration. This causes an
incorrect configuration when only the rt5682 is present on a
Google_Hatch device.

For CML, the jack codec is used as the primary key when matching,
with a possible speaker amplifier described in quirk_data. The two cases
of interest are the second and third 10EC5682 entries in
snd_soc_acpi_intel_cml_machines[]. The second entry matches the
combination of rt5682 and max98357a, resulting in the quirk_data field
in the snd_soc_acpi_mach being non-null, pointing at
max98357a_spk_codecs, the snd_soc_acpi_codecs for the matched speaker
amplifier. The third entry matches just the rt5682, resulting in a null
quirk_data.

The sof_rt5682 driver's DMI data matching identifies that a speaker
amplifier is present for all Google_Hatch family devices. Detect cases
where there is no speaker amplifier by checking for a null quirk_data in
the snd_soc_acpi_mach and remove the speaker amplifier bit in that case.

[alsa-devel] [PATCH AUTOSEL 5.5 333/542] ALSA: usb-audio: Add boot quirk for MOTU M Series

[Sasha Levin]

From: Alexander Tsoy <alexander@tsoy.me>

[ Upstream commit 73ac9f5e5b43a5dbadb61f27dae7a971f7ec0d22 ]

Add delay to make sure that audio urbs are not sent too early.
Otherwise the device hangs. Windows driver makes ~2s delay, so use
about the same time delay value.

snd_usb_apply_boot_quirk() is called 3 times for my MOTU M4, which
is an overkill. Thus a quirk that is called only once is implemented.

Also send two vendor-specific control messages before and after
the delay. This behaviour is blindly copied from the Windows driver.

[alsa-devel] [PATCH AUTOSEL 5.5 335/542] ASoC: txx9: Remove unused rtd variable

[Sasha Levin]

From: Paul Burton <paulburton@kernel.org>

[ Upstream commit ec0f6a4c4a987aa20b2e77e0db2ae555276e45e6 ]

Commit a857e073ffc6 ("ASoC: txx9: txx9aclc: remove snd_pcm_ops") removed
the last use of the rtd variable but didn't remove its definition,
leading to the following warning/error for MIPS rbtx49xx_defconfig
builds:

sound/soc/txx9/txx9aclc.c: In function 'txx9aclc_pcm_hw_params':
sound/soc/txx9/txx9aclc.c:54:30: error: unused variable 'rtd'
    [-Werror=unused-variable]
  struct snd_soc_pcm_runtime *rtd = snd_pcm_substream_chip(substream);
                              ^~~

Resolve this by removing the unused variable.

[Sasha Levin]

From: Alexander Tsoy <alexander@tsoy.me>

[ Upstream commit c249177944b650816069f6c49b769baaa94339dc ]

This fixes crackling sound during playback.

Further note: MOTU is known for reusing Product IDs for different
devices or different generations of the device (e.g. MicroBook
I/II/IIc shares a single Product ID). This patch was only tested with
M4 audio interface, but the same Product ID is also used by M2. Hope
it will work for M2 as well.

From: Charles Keepax <ckeepax@opensource.cirrus.com>

[ Upstream commit 73ecf1a673d3502dff1445f06675aba65ff20ce7 ]

The recently added API that exposes firmware mixer controls to the
kernel is missing cache handling and all writes bypass the cache, this
obviously causes the cache to get out of sync with the hardware. Factor
out the cache handling into two new helper functions and call those from
both the normal ALSA control handlers and the new kernel API.

[alsa-devel] [PATCH AUTOSEL 5.5 406/542] ASoC: SOF: Intel: hda: Fix SKL dai count

[Sasha Levin]

From: Cezary Rojewski <cezary.rojewski@intel.com>

[ Upstream commit a6947c9d86bcfd61b758b5693eba58defe7fd2ae ]

With fourth pin added for iDisp for skl_dai, update SOF_SKL_DAI_NUM to
account for the change. Without this, dais from the bottom of the list
are skipped. In current state that's the case for 'Alt Analog CPU DAI'.

This patch generates a kernel oops with v5.5.6 - mainly because the 
initial commit ac42b142cd76 is missing, which ends-up creating an empty 
entry in the skl_dai[] array.

This was just reported to us, see logs at
https://github.com/thesofproject/sof/issues/2418

the same problem is likely to happen with 5.4-stable
[PATCH AUTOSEL 5.4 349/459] ASoC: SOF: Intel: hda: Fix SKL dai count

Since the initial commit to be fixed was not included, the -stable 
branches should probably revert this patch? Adding ac42b142cd76 should 
also not generate any problems, I tested it on top of v5.5.6

The 'right' fix should be to use ARRAY_SIZE instead of hard-coded 
defines, but there are multiple dependencies so we'd probably need to 
refactor the code to so so.

Let me know if you want more details or additional help,
-Pierre

[alsa-devel] [PATCH AUTOSEL 5.5 426/542] ALSA: hda/hdmi - add retry logic to parse_intel_hdmi()

[Sasha Levin]

From: Kai Vehmanen <kai.vehmanen@linux.intel.com>

[ Upstream commit 2928fa0a97ebb9549cb877fdc99aed9b95438c3a ]

The initial snd_hda_get_sub_node() can fail on certain
devices (e.g. some Chromebook models using Intel GLK).
The failure rate is very low, but as this is is part of
the probe process, end-user impact is high.

In observed cases, related hardware status registers have
expected values, but the node query still fails. Retrying
the node query does seem to help, so fix the problem by
adding retry logic to the query. This does not impact
non-Intel platforms.

[alsa-devel] [PATCH AUTOSEL 5.5 489/542] ASoC: Intel: consistent HDMI codec probing code

[Sasha Levin]

From: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>

[ Upstream commit 98ff5c262f27aafee077a4c096f71a8566e9e948 ]

Multiple Intel ASoC machine drivers repeat the same pattern in their
.late_probe() methods: they first check whether the common HDMI codec
driver is used, if not, they proceed by linking the legacy HDMI
driver to each HDMI port. While doing that they use some
inconsistent code:

1. after the loop they check, whether the list contained at least one
   element and if not, they return an error. However, the earlier
   code to use the common HDMI driver uses the first element of the
   same list without checking. To fix this we move the check to the
   top of the function.

2. some of those .late_probe() implementations execute code, only
   needed for the common HDMI driver, before checking, whether the
   driver is used. Move the code to after the check.

3. Some of those functions also perform a redundant initialisation of
   the "err" variable.

This patch fixes those issues.
