ASoC: SOF: ipc4-loader: remove the CPC check warnings

2024-01-25T23:35:58+00:00

[ Upstream commit ab09fb9c629ed3aaea6a82467f08595dbc549726 ] 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-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.

ASoC: SOF: ipc4: Convert the firmware handling (loader) to library convention

2022-10-21T12:05:01+00:00

With IPC4 each DSP loadable binary is a library, which contains ext_manifest section and loadable modules. The basefw is no exception, it is always library 0 and it can contain several modules, depending on the firmware build. The current code assumes only one binary, which is the basefw and has no concept of libraries. This patch introduces the library+modules abstraction and represents the basefw as library for the IPC4 loader codebase. The basefw loading and handling is not changing, it is still done by the generic code, but it's information is cloned under the library representation. The libraries are managed via XArray to offload the list and ID management.
