ASoC: SOF: ipc4-topology: Add new tokens for pipeline direction

2026-02-04T13:26:05+00:00

Parse the pipeline direction from topology. The direction_valid token is
required for backward-compatibility with older topologies that may not
have the direction set for pipelines. This will be used when
setting up pipelines to check if a pipeline is in the same direction as
the requested params and skip those in the opposite direction like in
the case of echo reference capture pipelines during playback.

ASoC: sof: ipc4-topology: Add topology tokens domain_in stack & heap_bytes

2026-01-12T11:48:37+00:00

Add topology tokens for defining user-space domain_id, required stack
and heap size byte for a component. The new topology tokens are
SOF_TKN_COMP_DOMAIN_ID, SOF_TKN_COMP_HEAP_BYTES_REQUIREMENT and
SOF_TKN_COMP_STACK_BYTES_REQUIREMENT for defining required stack and
heap size for a component.

ASoC: Intel: avs: Honor NHLT override when setting up a path

2025-11-16T23:59:05+00:00

In case topology provides NHLT configuration, use it instead of relying
on the table in ACPI tree. Only gateway-related modules e.g.: Copier
care about the process. For those the order of fetching for hardware
configuration becomes:

1) check if NHLT override is set,
2) check if NHLT descriptor override is set,
3) use NHLT from ACPI directly

Such approach ensures no conflicts exist between 1) and 2) and that 1)
always takes precedence.

ASoC: Intel: avs: Allow the topology to carry NHLT data

2025-11-16T23:59:04+00:00

Typically the hardware configuration for I2S and DMIC devices resides
in the Non-HDAudio Link Table (NHLT) that is part of the ACPI tree. As
the NHLTs existing in the field are not always perfect, workaround
mechanisms are provided to patch them.

Currently the avs-driver is utilizing the ->blob_fmt override (see
topology.h and struct avs_tplg_modcfg_ext) when there is a valid entry
within a NHLT to configure the hardware for specific format but its
descriptor (header) is invalid.

A separate case is when there is no correct hardware configuration at
all within the NHLT available in the system. Patching the header won't
help and forcing ad-hoc BIOS updates for dated system is not feasible.
Allowing the topology to carry the data is the solution of choice as
replacing a userspace file that is part of /lib/firmware/intel/ is less
invasive than BIOS update and solves the problem.

ALSA: compress: document 'chan_map' member in snd_dec_opus

2025-09-28T06:29:03+00:00

When building kernel docs, the following warning appeared:

  WARNING: ./include/uapi/sound/compress_params.h:364
  struct member 'chan_map' not described in 'snd_dec_opus'

The inline struct 'snd_dec_opus_ch_map' inside 'snd_dec_opus' was not
properly documented. This patch documents the 'chan_map' member and its
fields (stream_count, coupled_count, channel_map), resolving the warning.

Merge tag 'asoc-v6.18' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next

2025-09-20T06:38:17+00:00

ASoC: Updates for v6.18

A relatively quiet release for ASoC, we've had a lot of maintainance
work going on and several new drivers but really the most remarkable
thing is that we removed a driver, the WL1273 driver used in some old
Nokia systems that have had the underlying system support removed from
the kernel.

 - Morimoto-san continues his work on cleanups of the core APIs and
   enforcement of abstraction layers.
 - Lots of cleanups and conversions of DT bindings.
 - Substantial maintainance work on the Intel AVS drivers.
 - Support for Qualcomm Glymur and PM4125, Realtek RT1321, Shanghai
   FourSemi FS2104/5S, Texas Instruments PCM1754.
 - Remove support for TI WL1273.

ALSA: compress: add raw opus codec define and opus decoder structs

2025-09-19T12:58:09+00:00

Adds a raw opus codec define and raw opus decoder structs.
This is for raw OPUS packets not packed in any type of container
(for instance OGG container). The decoder struct fields are
taken from corresponding RFC document: RFC 7845 Section 5.
