ASoC: soc-acpi / SOF: Add best_effort flag to get_function_tplg_files op

2025-12-15T14:08:35Z

When there is no fallback possibility available for the function topology use it is better to try to create a profile for the card in best effort manner, leaving out non supported links for example. As an example: some laptops present SSPx-BT link but we don't have fragment yet to support this. If we only have support for functional topology without monolithic fallback then we would fail the card creation. The reason why the monolithic topology works on the same device is that it does not have the SSPx-BT link handled, it is ignored. In case when there is no fallback possibility we should try to create the card with links that we support as best effort instead of failing and leaving the user without a card.

ASoC: soc-acpi: make some variables of acpi adr and link adr non-const

2025-10-13T10:23:22Z

Currently, we use predefined snd_soc_acpi_link_adr tables to match the link adr from ACPI table to select the machine driver and the topology. However, with the mechanism, we need to create the snd_soc_acpi_link_adr table for each audio config. The sof_sdw machine driver is used by almost all Intel platforms with SOF and we can load required topology file dynamically today. In other words, we can use sof_sdw machine driver as the default machine driver for Intel SOF SoundWire codecs and no need to create snd_soc_acpi_link_adr table for every new audio configs. To achieve it, we need to drop the const for some members and edit the link adr and acpi adr data to match the data from the ACPI table.

ASoC: soc-acpi: add get_function_tplg_files ops

2025-04-14T10:22:18Z

We always use a single topology that contains all PCM devices belonging to a machine configuration. However, with SDCA, we want to be able to load function topologies based on the supported device functions. This change is in preparation for loading those function topologies.

ASoC: soc-acpi: introduce new 'machine check' callback

2024-10-17T17:42:14Z

The existing machine_quirk() returns a pointer to a soc_acpi_mach structure. For SoundWire/SDCA support, we need a slightly different functionality where a quirk function either validates or NACKs an initial selection, based on additional firmware/DMI information.

ASoC/soundwire: remove sdw_slave_extended_id

2024-10-17T17:42:10Z

This structure is used to copy information from the 'sdw_slave' structures, it's better to create a flexible array of 'sdw_slave' pointers and directly access the information. This will also help access additional information stored in the 'sdw_slave' structure, such as an SDCA context. This patch does not add new functionality, it only modified how the information is retrieved.

ASoC: SOF: Intel: hda: support BT link mask in mach_params

2024-08-28T12:01:57Z

Add an new variable bt_link_mask to snd_soc_acpi_mach_params structure. SSP port mask of BT offload found in NHLT table will be sent to machine driver to setup BE dai link with correct SSP port number. This patch only detects and enables the BT dailink. The functionality will only be unlocked with a topology file that makes a reference to that BT dailink. For backwards-compatibility reasons, this topology will not be used by default. Chromebooks and Linux users willing to experiment shall use the tplg_name kernel parameter to force the use of an enhanced topology.

Merge tag 'asoc-v6.10' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2024-05-13T09:39:49Z

ASoC: Updates for v6.10 This is a very big update, in large part due to extensive work the Intel people have been doing in their drivers though it's also been busy elsewhere. There's also a big overhaul of the DAPM documentation from Luca Ceresoli arising from the work he did putting together his recent ELC talk, and he also contributed a new tool for visualising the DAPM state. - A new tool dapm-graph for visualising the DAPM state. - Substantial fixes and clarifications for the DAPM documentation. - Very large updates throughout the Intel audio drivers. - Cleanups of accessors for driver data, module labelling, and for constification. - Modernsation and cleanup work in the Mediatek drivers. - Several fixes and features for the DaVinci I2S driver. - New drivers for several AMD and Intel platforms, Nuvoton NAU8325, Rockchip RK3308 and Texas Instruments PCM6240.
