ASoC: SOF: topology: use kzalloc_flex

2026-03-30T19:11:31+00:00

Simplify allocation by using a flexible array member. Add __counted_by for extra runtime analysis. Signed-off-by: Rosen Penev Link: https://patch.msgid.link/20260326023053.53493-1-rosenp@gmail.com Signed-off-by: Mark Brown

ASoC: SOF: sof-audio: pcm_id is __le32

2026-03-10T14:53:04+00:00

The pcm_id value is __le32 so convert it before passing to the dev_dbg function to be printed. Also fixup some other uses of __le32 data and a couple of places where %u should have been used instead of %d Picked up by sparse prototype for variadic and printf function checking. Fixes a large number of sparse warnings, such as: sound/soc/sof/pcm.c:84:25: warning: incorrect type in argument 4 (different base types) sound/soc/sof/pcm.c:84:25: expected unsigned int sound/soc/sof/pcm.c:84:25: got restricted __le32 [usertype] pcm_id Signed-off-by: Ben Dooks Acked-by: Peter Ujfalusi Link: https://patch.msgid.link/20260310125106.178944-1-ben.dooks@codethink.co.uk Signed-off-by: Mark Brown

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: pcm: Split up widget prepare and setup

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

Widgets are set up in 2 steps, first ipc_prepare followed by the actual IPC sent to the DSP to set up the widget. Split these 2 steps to do the ipc_prepare during hw_params and the setting up in the prepare callback. This will allow for future modifications to pipeline set up to be split up between the FE and BE DAI prepare ops.

ASoC: SOF: sof-audio: Add a new op in struct sof_ipc_tplg_ops

Add a new host_config op in struct sof_ipc_tplg_ops and define it for IPC4. This will be used to configure the host widget during prepare after a suspend/resume or after an xrun.

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: SOF: Relocate and rework functionality for PCM stream freeing

2025-02-06T11:25:41+00:00

Move the sof_pcm_stream_free() from sof-audio.c to pcm.c as static function and add wrapper to free all active stream, which is going to be used in ipc3/4 topology code (removes duplicated code). With this change most of the PCM stream related code is located in one source file for easier lookup and simplified flow.
