ASoC: SOF: Intel: hda: Add a virtual CPU DAI

2026-02-04T13:26:10+00:00

Add a virtual CPU DAI for loopback capture for echo reference implementation. We can't use the snd-soc-dummy-dai because it is already used for the bluetooth DAI link.

ASoC: SOF: Intel: add hda_dma_prepare/cleanup helpers

2026-02-03T13:47:20+00:00

SoundWire BPT stream needs to use link and host DMAs. Thus we need helpers to prepare and cleanup the link and host DMAs. Currently the SoundWire BPT stream uses hda_cl_prepare/cleanup helpers. It works fine because we assume the SwoundWire BPT will not run with audio streams simultaneously. The new helpers are copied from hda_cl_prepare/cleanup and add a flag to reserve the paired host and link DMAs. The new helpers will be used by both code loader and SoundWire BPT.

ASoC: SOF: Intel: add hda_dsp_stream_pair_get/put helpers

2026-02-03T13:47:19+00:00

Currently, hda_dsp_stream_get/put are used to get/put the host dma. However, we may want to use a hda stream that both host and link dma are available. Add helper to find the hda stream and reserve/release it.

ASoC: SOF: Intel: only detect codecs when HDA DSP probe

2025-08-29T08:50:37+00:00

SDW codecs use the global HDaudio WAKEEN/STS to detect wakes since LNL. But the wake event is handled in the SDW driver. We should only clear WAKESTS for the HDA and IDISP codecs that was detected when HDA DSP probe. The SoundWire codec will be included in the codec_mask if we read the STATESTS register when a SoundWire codec wake event happens. The commit avoid updating bus->codec_mask in resume to not clear WAKESTS of SoundWire codecs.

ASoC: SOF: hda/ptl: Move mic privacy change notification sending to a work

2025-03-31T11:51:55+00:00

IPC message cannot be sent from the irq thread directly as the message will not receive the reply (interrupts are disabled) and it will time out - the reply is going to be received right after the we leave the irq thread. This is a different case compared to the delayed IPC messages due to DSP busy state. Add support for sending the mic privacy change notification to the firmware from a work instead of the process callback. The work needs to be canceled if there is a chance that it might be running on module remove or before system/runtime suspend.

ASoC: SOF: Intel: lnl/ptl: Only set dsp_ops which differs from MTL

LunarLake is a next generation in ACE architecture and most of the dsp_ops are the same as it is in previous generation. Use the sof_mtl_set_ops() to get the ops used for mtl and update the ones that needs different functions for LNL. Update pci-ptl at the same time to use the LNL dsp_ops as before.
