ASoC: SOF: Introduce container struct for SOF firmware

2024-03-26T22:20:48+00:00

[ Upstream commit 4f373ccf226e37a20fdc15a3df8034517a6045fd ] Move the firmware related information under a new struct (sof_firmware) and add it to the high level snd_sof_dev struct. Convert the generic code to use this new container when working with the basefw and for compatibility reasons set the old plat_data members used by the platforms.

ASoC: SOF: ipc4: Add support for mtrace log extraction

2022-09-09T17:48:48+00:00

One of the debugging/logging features for an IPC4 based firmware is the use of the debug window to deliver log messages to host via the shared SRAM. The initial implementation of the mtrace supports only TGL/MTL style of logging, but can be extended to support other types, like APL, SKL, CNL, etc. The window is split into 16 'slots' where the first slot contains the descriptors for the remaining 15 slots. Each DSP core logs to a separate slot and the slot allocation is not fixed, we can not assume that the first slot is always used by core0 for example. The firmware sends LOG_BUFFER_STATUS message when new log batch is available from one of the cores (after it updated the write_ptr in the given slot). Host should update the read_ptr in the same slot when it has taken out log data. The patch also updates the sof_ipc4_fw_data struct with parameters needed for the mtrace to be enabled and used safely.

ASoC: SOF: ipc4-loader: Verify ext manifest magic number

2022-08-23T18:52:38+00:00

Firmware image must start with an extended manifest. Add a check to make sure that the image does contain it. The magic number (the first u32 of a firmware image if manifest is present) for an IPC4 image must be 0x31454124 (ASCI "$AE1").

ASoC: SOF: IPC4: Add FW loader ops

2022-05-12T10:41:28+00:00

Define and add the FW loader ops for IPC4. Also, introduce a new structure, struct sof_ipc4_private_data that will be used to define some IPC4-sepcific data.
