The payload to specify memory requirements of Data Processing components, running as independent processes in SOF firmware. But more importantly it adds a payload of similar purpose to the pipeline create message, e.g. sof_ipc4_glb_pipe_payload. It sums up the memory requirements of individual Low Latency components in the pipeline and sends the summed up values in pipeline create message.

ASoC: SOF: ipc4: Add support for Intel HW managed mic privacy messaging 2025-03-08T16:06:40+00:00 Peter Ujfalusi peter.ujfalusi@linux.intel.com 2025-03-07T11:28:13+00:00 eea84a7f0cdb693c261a7cf84bd4b3d81479c9a6 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.
