ASoC: SOF: ipc4-pcm: Harmonize set pipeline state dbg

2025-06-20T10:33:05Z

Merge series from Peter Ujfalusi : The series harmonizes the debug prints for pipeline state changes. Currently we only print readable state change for single pipeline changes but when multiple pipeline's state is changed, it is omitted. Use human readable information in both cases in a harmonized way to aid debugging.

ASoC: SOF: ipc4: Add sof_ipc4_pipeline_state_str() for debugging

2025-06-19T12:19:53Z

Add sof_ipc4_pipeline_state_str() to translate enum sof_ipc4_pipeline_state into human readable form.

ASoC: SOF: ipc4/Intel: Add support for library restore firmware functionality

2025-06-19T12:19:35Z

The firmware will be able to only save and restore the context related to library management. This means that even without a full context save, the libraries do not need to be re-loaded to the firmware after second or consecutive boots. This is reported via the FW_READY notification, where BIT(15) indicates: 0 - the library restore is not done 1 - library restore is done This bit is only valid if full context save is not enabled, full context save is by definition saves and restores the library related book-keeping as well. Add a new flag to tell the platform code if the libraries have been restored, no need to reload them after boot.

ASoC: SOF: ipc4: Add support for Intel HW managed mic privacy messaging

2025-03-08T16:06:40Z

ACE3 (Panther Lake) introduced support for microphone privacy feature which can - in hardware - mute incoming audio data based on a state of a physical switch. The change in the privacy state is delivered through interface IP blocks and can only be handled by the link owner. In Intel platforms Soundwire is for example host owned, so the interrupt can only be handled by the host. Since the input stream is going to be muted by hardware, the host needs to send a message to firmware about the change in privacy so it can execute a fade out/in to enhance user experience. The support for microphone privacy can be queried from the HW_CONFIG data under the INTEL_MIC_PRIVACY_CAP tuple. This is Intel specific data, the core will pass it to platform code if the intel_configure_mic_privacy() callback is provided. Platform code can call sof_ipc4_mic_privacy_state_change() to send the IPC message to the firmware on state change.

ASoC: SOF: ipc4: Add support for split firmware releases

2025-02-06T16:28:02Z

A split SOF release consists of a base firmware and two libraries: -openmodules.ri for processing (audio) modules -debug.ri for debug and developer modules To handle this new release model add infrastructure to try to load the two library after boot optionally. This approach will allow flexibility on handling platforms in sof-bin with single or split configuration: single release: base firmware only split release: base firmware + openmodules + debug The files for the split firmware are located at the firmware directory.

ASoC: SOF: Intel: clarify Copyright information

For some reason a number of files included the "All rights reserved" statement. Good old copy-paste made sure this mistake proliferated. Remove the "All rights reserved" in all Intel-copyright to align with internal guidance.

The sof_ipc4_timestamp_info is only used by ipc4-pcm.c internally, it should not be in a generic header implying that it might be used elsewhere.
