ASoC: SOF: Prepare set_stream_data_offset for compress API

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

[ Upstream commit 249f186d6b0211fc59d83db128030f2b298063a1 ] Make second parameter of set_stream_data_offset generic in order to be used for both PCM and compress streams. Current patch doesn't introduce any functional change, just prepare the code for compress support.

ASoC: SOF: Prepare ipc_msg_data to be used with compress API

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

[ Upstream commit 1b905942d6cd182b7ef14e9f095178376d3847e6 ] Make second parameter of ipc_msg_data generic in order to be able to support compressed streams. This patch doesn't hold any functional change. With this case we can use ipc_msg_data, to retrieve information from DSP for both PCM/Compress API.

ASoC: SOF: remove const qualifier for 'struct snd_sof_dsp_ops'

2022-04-19T11:03:39+00:00

Now that we start having multiple platforms with minor variants, the use of the const qualifier for 'dsp_ops' is starting to be sub-optimal: the structures are copied across platforms, with only a couple of members that differ. This patch removes the const qualifier without any functionality changes, and adds an optional initialization callback. In follow-up patches, the dsp_ops will revisited for Intel HDaudio platforms, with the differences added programmatically over a common baseline.
