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: Return ssize_t from sof_ipc4_fw_parse_ext_man()

2022-10-26T13:18:33+00:00

sof_ipc4_fw_parse_ext_man() can return negative error numbers which is not
correct for the used size_t type.

Change the return value to ssize_t and use the same type where the function
is called.

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.
