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.

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_offload: increase SNDRV_COMPRESS_VERSION minor version by 1

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

Since addition of raw opus codec support we need to update
compress API minor version by one.
Bump the SNDRV_COMPRESS_VERSION to 0.4.1.

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.

ALSA: compress_offload: Add SNDRV_COMPRESS_AVAIL64 ioctl

2025-09-08T07:33:24+00:00

The previous patch introduced a 64-bit timestamp ioctl
(SNDRV_COMPRESS_TSTAMP64). To provide a consistent API, this patch
adds a corresponding 64-bit version of the SNDRV_COMPRESS_AVAIL ioctl.

A new struct snd_compr_avail64 is added to the UAPI, which includes
the 64-bit timestamp. The existing ioctl implementation is refactored
to handle both the 32-bit and 64-bit variants.

ALSA: compress_offload: Add SNDRV_COMPRESS_TSTAMP64 ioctl

2025-09-08T07:33:24+00:00

The previous patch introduced the internal infrastructure for handling
64-bit timestamps. This patch exposes this capability to user-space.

Define the new ioctl command SNDRV_COMPRESS_TSTAMP64, which allows
applications to fetch the overflow-safe struct snd_compr_tstamp64.

The ioctl dispatch table is updated to handle the new command by
calling a new snd_compr_tstamp64 handler, while the legacy path is
renamed to snd_compr_tstamp32 for clarity.

This patch bumps the SNDRV_COMPRESS_VERSION to 0.4.0.

ALSA: compress_offload: Add 64-bit safe timestamp infrastructure

2025-09-08T07:33:24+00:00

The copied_total field in struct snd_compr_tstamp is a 32-bit
value that can overflow on long-running high-bitrate streams,
leading to incorrect calculations for buffer availablility.

This patch adds a 64-bit safe timestamping mechanism.
A new UAPI struct, snd_compr_tstamp64, is added which uses 64-bit
types for byte counters. The relevant ops structures across the
ASoC and core compress code are updated to use this new struct.
ASoC drivers are updated to use u64 counters.

Internal timestamps being u64 now, a compatibility function is added
to convert the 64-bit timestamp back to the 32-bit format for legacy
ioctl callers.

ASoC: sof: ipc4-topology: Add support to sched_domain attribute

2025-08-29T18:52:20+00:00

Add SOF_TKN_COMP_SCHED_DOMAIN and connect it to struct snd_sof_widget
comp_domain member, with new get_token_comp_domain() function.

The logic is such that if the topology attribute is not present in the
widget node the corresponding IPC4 extension value is taken from the
module's manifest like before. But if the attribute is found and
recognized its value overrides what is there in the manifest.

ASoC: qcom: audioreach: cleanup and calibration

2025-08-19T17:45:33+00:00

Merge series from srinivas.kandagatla@oss.qualcomm.com:

Sorry to resend this series once again, as some of the patches seems
to be dropped/rejected by email client from previous send.

This patchset:
 - cleans up some of the audioreach tokens which are unused
 - adds missing documentation
 - add support for static calibration support which is required for ECNS
   an speaker protection support.

Tested this with Single Mic ECNS on SM8450 platform.
