2025-01-15ASoC: dapm: add support for preparing streamsMartin Blumenstingl1-0/+12
Codec driver can implement .hw_params and/or .prepare from struct snd_soc_dai_ops. For codec-to-codec links only the former (.hw_params) callback has been called. On platforms like Amlogic Meson8/8b/8m2 the SoC's sound card (sound/soc/meson/gx-card.c) uses a codec-to-codec link for the HDMI codec output because further digital routing is required after the backend. The new DRM HDMI (audio) codec framework (which internally uses sound/soc/codecs/hdmi-codec.c) relies on the .prepare callback of the hdmi-codec to be called. Implement calls to snd_soc_dai_prepare() so the .prepare callback is called. In this case the mandatory part is the call to prepare the sink (which is the hdmi-codec on those platforms). Also call snd_soc_dai_prepare() for the source to stay consistent with the rest of the code (even though it's not strictly necessary to make the DRM HDMI codec framework work on Amlogic Meson8/8b/8m2). For platforms or sound cards without a codec-to-codec link with additional parameters (which applies to most hardware) this changes nothing as the .prepare callback is already called via snd_pcm_do_prepare() (as well as dpcm_fe_dai_prepare() and dpcm_be_dai_prepare()) on those.

2024-10-28ASoC: dapm: fix bounds checker error in dapm_widget_list_createAleksei Vetrov1-0/+2
The widgets array in the snd_soc_dapm_widget_list has a __counted_by attribute attached to it, which points to the num_widgets variable. This attribute is used in bounds checking, and if it is not set before the array is filled, then the bounds sanitizer will issue a warning or a kernel panic if CONFIG_UBSAN_TRAP is set. This patch sets the size of the widgets list calculated with list_for_each as the initial value for num_widgets as it is used for allocating memory for the array. It is updated with the actual number of added elements after the array is filled.

2024-10-08ASoC: dapm: avoid container_of() to get componentBenjamin Bara1-2/+2
The current implementation does not work for widgets of DAPMs without component, as snd_soc_dapm_to_component() requires it. If the widget is directly owned by the card, e.g. as it is the case for the tegra implementation, the call leads to UB. Therefore directly access the component of the widget's DAPM to be able to check if a component is available.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v6.12 This is a very large set of changes, almost all in drivers rather than the core. Even with the addition of several quite large drivers the overall diffstat is negative thanks to the removal of some old Intel board support which has been obsoleted by the AVS driver, helped a bit by some factoring out into helpers (especially around the Soundwire machine drivers for x86). Highlights include: - More simplifications and cleanups throughout the subsystem from Morimoto-san. - Extensive cleanups and refactoring of the Soundwire drivers to make better use of helpers. - Removal of Intel machine support obsoleted by the AVS driver. - Lots of DT schema conversions. - Machine support for many AMD and Intel x86 platforms. - Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek RTL1320 SoundWire and rev C, and Texas Instruments TAS2563

2024-04-21ASoC: dapm: debugfs: show the widget typeLuca Ceresoli1-0/+47
To make the widget debugfs files more informative, add a line showing the widget type string. Keeping backward compatibility is nice to have being debugfs, and ease of parsing by both humans and software is also good. To maximize both with a reasonable effort add a new line without thouching the already complex format of the first line. The syntax is meant to be a key/value pair. The existing vizdapm tool continues working after this change, ignoring the new line. The new format is: Left ADC: Off in 1 out 0 - R2(0x2) mask 0x2 stream Left HiFi Capture inactive widget-type adc out "static" "Capture" "cs42l51.0-004a" in "static" "Left PGA" "cs42l51.0-004a" Signed-off-by: Luca Ceresoli <luca.ceresoli@bootlin.com> Reviewed-by: Alexandre Belloni <alexandre.belloni@bootlin.com> Link: https://lore.kernel.org/r/20240416-vizdapm-ng-v1-2-5d33c0b57bc5@bootlin.com Signed-off-by: Mark Brown <broonie@kernel.org>
2024-04-21ASoC: dapm: debugfs: add component to route linesLuca Ceresoli1-2/+5
debugfs entries for DAPM widgets have the following form: Left ADC: Off in 1 out 0 - R2(0x2) mask 0x2 stream Left HiFi Capture inactive out "static" "Capture" in "static" "Left PGA" Lines with the "in" and "out" prefixes describe routes from/to other widgets presenting the path name and the connected widget name. This is ambiguous in case of cards having multiple widgets with the same name in different components. For example the STM32MP157A-DK1 board (arch/arm/boot/dts/st/stm32mp15xx-dkx.dtsi) has a "Capture" widget in both the "cs42l51.0-004a" and the "hdmi-audio-codec.1.auto" components. Avoid the ambiguity by adding the component name to the "in" and "out" lines. Add the new field at the end to minimize backward compatibility issues.

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct snd_soc_dapm_widget_list. Additionally, since the element count member must be set before accessing the annotated flexible array member, move its initialization earlier.

2023-08-15ASoC: dapm: Add a flag for not having widget name in kcontrol nameJyri Sarha1-0/+2
The existing soc-dapm code may add a prefix to control names, which in some cases is useful but in others leads to long and confusing kcontrol names such as "gain 2.1 Main Playback Volume". This patch suggests an added flag to prevent the widget name prefix from being added. That flag will be set in the topology file on a per-widget basis. The flag no_wname_in_kcontrol_name is added to struct snd_soc_dapm_widget, and the logic in dapm_create_or_share_kcontrol() is changed to not to add widget name if the flag is set.

2023-06-13ASoC: add N cpus to M codecs dai link supportBard Liao1-1/+23
Currently, ASoC supports dailinks with the following mappings: 1 cpu DAI to N codec DAIs N cpu DAIs to N codec DAIs But the mapping between N cpu DAIs and M codec DAIs is not supported. The reason is that we didn't have a mechanism to map cpu and codec DAIs This patch suggests a new snd_soc_dai_link_codec_ch_map struct in struct snd_soc_dai_link{} which provides codec DAI to cpu DAI mapping information used to implement N cpu DAIs to M codec DAIs support. When a dailink contains two or more cpu DAIs, we should set channel number of cpus based on its channel mask. The new struct also provides channel mask information for each codec and we can construct the cpu channel mask by combining all codec channel masks which map to the cpu. The N:M mapping is however restricted to the N <= M case due to physical restrictions on a time-multiplexed bus such as I2S/TDM, AC97, SoundWire and HDaudio.

When a widget is added to dapm via snd_soc_dapm_new_widgets, dapm_debugfs_add_widget is also called to create a corresponding debugfs file. However, when a widget is freed by snd_soc_dapm_free_widget, the corresponding debugfs is not cleared. As a result, the freed widget is still seen in the dapm directory. This patch adds dapm_debugfs_free_widget to free the debugfs of a specified widget, and it's called at snd_soc_dapm_free_widget to clean up the debugfs for freed widget.

2023-04-17ASoC: expand snd_soc_dapm_mutex_lock/unlock()Kuninori Morimoto1-61/+58
soc.h has snd_soc_dapm_mutex_lock/unlock() definition and many drivers are using it, but soc-dapm.c is not. 1st reason is snd_soc_dapm_mutex_lock/unlock() requests snd_soc_dapm_context pointer as parameter (A), but sometimes soc-dapm.c needs to use snd_soc_card (B). (A) static inline void snd_soc_dapm_mutex_lock(struct snd_soc_dapm_context *dapm) { mutex_lock_nested(&dapm->card->dapm_mutex, SND_SOC_DAPM_CLASS_RUNTIME); } ^^^^^^^^^^ (B) mutex_lock_nested(&card->dapm_mutex, SND_SOC_DAPM_CLASS_RUNTIME); ^^^^ 2nd reason is it want to use SND_SOC_DAPM_CLASS_INIT for mutex_lock_nested(), but helper is using _RUNTIME (A). The conclusion is we want to use "dapm vs card" and "_RUNTIME vs _INIT" for dapm lock/unlock. To enable this selfish request, this patch uses _Generic macro. We can use snd_soc_dapm_mutex_lock/unlock() for both dapm and card case. snd_soc_dapm_mutex_lock(dapm); snd_soc_dapm_mutex_unlock(dapm); snd_soc_dapm_mutex_lock(card); snd_soc_dapm_mutex_unlock(card); Current soc-dapm.c is using both mutex_lock() and mutex_lock_nested(). This patch handles mutex_lock() as mutex_lock_nested(..., 0), in other words, handles below as same. mutex_lock(&card->dapm_mutex); mutex_lock_nested(&card->dapm_mutex, SND_SOC_DAPM_CLASS_INIT); Because people might misunderstand that _init() is mutex initialization, this patch renames _INIT to _ROOT and adds new snd_soc_dapm_mutex_lock_root() for it. This patch also moves snd_soc_dapm_subclass definition from soc-dapm.h to soc.h to keep related code together. Because very complex soc.h vs soc-dapm.h relationship, it is difficult/impossible to define these helper into soc-dapm.h.

Currently we sequence speakers with line and headphone outputs in DAPM. This works well when speakers are integrate into a CODEC but when there is an external speaker driver connected to a line or headphone output it can mean that the speaker driver ends up getting sequenced such that it picks up pops and clicks from the CODEC. Mask this by moving speakers after the other outputs in DAPM. We may want to consider doing this for headphones too but separate drivers are less common there and headphone drivers often also function as line outputs so the situation is less clear.
