ASoC: SOF: compress: return the configured codec from get_params

2026-06-01T15:39:13+00:00

[ Upstream commit 2c4fdd055f92a2fc8602dcd88bcea08c374b7e8b ] The SOF compressed offload path accepts codec parameters in sof_compr_set_params() and forwards them to firmware as extended data in the SOF IPC stream params message. However, sof_compr_get_params() still returns success without filling the snd_codec structure. Since the compress core allocates that structure zeroed and copies it back to userspace on success, SNDRV_COMPRESS_GET_PARAMS returns an all-zero codec description even after the stream has been configured successfully. The stale TODO in this callback conflates get_params() with capability discovery. Supported codec enumeration belongs in get_caps() and get_codec_caps(). get_params() should report the current codec settings. Cache the codec accepted by sof_compr_set_params() in the per-stream SOF compress state and return it from sof_compr_get_params().

ASoC: SOF: Add support for compress API for stream data/offset

2026-06-01T15:39:13+00:00

[ Upstream commit 090349a9feba3ceee3997d31d68ffe54e5b57acb ] snd_sof_pcm_stream keeps information about both PCM (snd_pcm_substream) and Compress (snd_compr_stream) streams. When PCM substream pointer is NULL this means we are dealing with a compress stream.

ASoC: SOF: add quirk to override topology mclk_id

2022-09-19T17:11:45+00:00

Some Intel-based platforms rely on a topology file that hard-codes the use of MCLK0. This is incorrect in 10% of the cases. Rather than generating yet another set of topology files, this patch adds a kernel module parameter to override the topology value. In hindsight, we should never have allowed mclks to be specified in topology, this is a hardware-level information that should not have been visible in the topology. Future patches will try to set this value automagically, e.g. by parsing the NHLT content.

ASoC: SOF: compress: Save channel count and sample bytes

2022-08-17T12:00:23+00:00

The purpose of this change is to enable the saving of the channel count and sample container bytes format parameters for later use to compute the timestamps. This is done when setting the compress stream parameters (in sof_compr_set_params).
