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: ipc: replace "enum sof_comp_type" field with "uint32_t"

2024-08-26T18:29:39Z

Normally, the type of enums is "unsigned int" or "int". GCC has the "-fshort-enums" option, which instructs the compiler to use the smallest data type that can hold all the values in the enum (i.e: char, short, int or their unsigned variants). According to the GCC documentation, "-fshort-enums" may be default on some targets. This seems to be the case for SOF when built for a certain 32-bit ARM platform. On Linux, this is not the case (tested with "aarch64-linux-gnu-gcc") which means enums such as "enum sof_comp_type" will end up having different sizes on Linux and SOF. Since "enum sof_comp_type" is used in IPC-related structures such as "struct sof_ipc_comp", this means the fields of the structures will end up being placed at different offsets. This, in turn, leads to SOF not being able to properly interpret data passed from Linux. With this in mind, replace "enum sof_comp_type" from "struct sof_ipc_comp" with "uint32_t".

ASoC: SOF: ipc4: Add data struct for module notification message from firmware

2023-11-24T15:38:00Z

With the module notification message the information about the notification is provided via the mailbox with the sof_ipc4_notify_module_data struct. It contains the module and instance id of the sender of the notification, the event_id and optionally additional data which is module and event specific. At the same time add definitions to identify ALSA kcontrol change notification. These notifications use standardized event_id, modules must follow this if they support such notifications: upper 16 bit: 0xA15A as a magic identification value lower 16 bit: param_id of the changed control Signed-off-by: Peter Ujfalusi Reviewed-by: Ranjani Sridharan Reviewed-by: Pierre-Louis Bossart Link: https://lore.kernel.org/r/20231124150853.18648-3-peter.ujfalusi@linux.intel.com Signed-off-by: Mark Brown
