ASoC: SOF: ipc4-loader: Return ssize_t from sof_ipc4_fw_parse_ext_man()

2022-10-26T13:18:33Z

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

2022-10-21T12:05:11Z

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

2022-10-21T12:05:01Z

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.

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

2022-09-09T17:48:48Z

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.
