ASoC: SOF: ipc4: Support for sending payload along with LARGE_CONFIG_GET

2026-03-04T12:21:00+00:00

[ Upstream commit d96cb0b86d6e8bbbbfa425771606f6c1aebc318e ] There are message types when we would need to send a payload along with the LARGE_CONFIG_GET message to provide information to the firmware on what data is requested. Such cases are the ALSA Kcontrol related messages when the high level param_id tells only the type of the control, but the ID/index of the exact control is specified in the payload area. The caller must place the payload for TX before calling the set_get_data() and this payload will be sent alongside with the message to the firmware. The data area will be overwritten by the received data from firmware.

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.

ASoC: SOF: ipc4: Move window offset configuration earlier

2023-11-29T13:25:26+00:00

With the added exception handling support if the firmware fails to boot up we are trying to do a panic dump from the telemetry slot. The slot offsets would have been configured only after receiving the FW_READY message which makes this panic dump unusable for early boot failures. With IPC4 the DSP window offsets are at standard places unlike IPC3 where the offsets needs to be queried from the FW_READY message. Move the offset configuration to sof_ipc4_init from the fw_ready handler.

ASoC: SOF: ipc4: Handle ALSA kcontrol change notification from firmware

2023-11-24T15:38:01+00:00

The control change notification is sent as module notification with a standardized event_id (higher 16 bit is 0xA15A). Add generic code to handle the module notification and invoke the control update callback if the notification is an ALSA kcontrol change message.

ASoC: SOF: ipc4/Intel: Implement split fw library

2023-09-15T18:03:35+00:00

Merge series from Peter Ujfalusi : This series implements support for split library loading to comply with the HDA DMA programming sequence recommendation, which is: 1. DSP side DMA programming and GEN bit set to 1 2. host side DMA programming and RUN bit set to 1 The SOF support for library loading is based on this sequence, backwards compatibility with older reference firmware is supported (where only the LOAD_LIBRARY message is supported).
