ASoC: SOF: Intel: clarify Copyright information

2024-05-06T14:59:35+00:00

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-loader: remove the CPC check warnings

2024-01-15T14:04:52+00:00

Warnings related to missing data in firmware manifest have proven to be too verbose. This relates to description of DSP module cost expressed in cycles per chunk (CPC). If a matching value is not found in the manifest, kernel will pass a zero value and DSP firmware will use a conservative value in its place. Downgrade the warnings to dev_dbg().

ASoC: SOF: IPC4: query fw_context_save feature from fw

2023-12-15T12:57:56+00:00

Driver queries fw_context_save feature when fw is ready and can skip library reload with this feature since library is saved in persistent memory. The default value of fw_context_save is true unless fw reports false.

ASoC: SOF: ipc4-loader/topology: Query the CPC value from manifest

2023-05-22T10:18:38+00:00

The manifest's firmware module configuration section contains the measured CPC values along with a matching IBS/OBS values. The CPC can be looked up by looking for a matching IBS/OBS entry. In case of multiple matches we will use the highest CPC value. If there is no mod_cfg or no CPC value (all 0) or no match was found then print warning message and use 0 as CPC value.

ASoC: SOF: ipc4-loader: Support for loading external libraries

2022-10-21T12:05:11+00:00

In case the requested module is not available among the loaded libraries, try to load it as external library. The kernel will try to load the file from /.bin If the file found, then the ext manifest of it is parsed, placed it under XArray and the pointer to the module is returned to the caller. Releasing the firmware will be done on ipc cleanup time.
