ASoC: SOF: ipc4: Switch to use the sof_debug:bit11 to dump message payload

Use the SOF_DBG_DUMP_IPC_MESSAGE_PAYLOAD flag to print the message payload instead of the DEBUG_VERBOSE, which would need code modification and kernel re-compilation.

ASoC: SOF: ipc4: Ensure DSP is in D0I0 during sof_ipc4_set_get_data()

2023-03-22T13:17:27+00:00

The set_get_data() IPC op bypasses the check for the no_pm flag as done with the regular IPC tx_msg op. Since set_get_data should be performed when the DSP is in D0I0, set the DSP power state to D0I0 before sending the IPC's in sof_ipc4_set_get_data().

2023-01-27T12:14:11+00:00

When starting/stopping multiple streams in parallel, pipeline triggers and pipeline frees can get interleaved. So use the same mutex used for pipeline trigger to protect the pipeline frees as well. Rename the trigger_mutex to pipeline_state_mutex for more clarity.

ASoC: SOF: ipc4-pcm: Implement pipeline trigger reference counting

2023-01-27T12:14:10+00:00

Use the started_count and paused_count to implement reference counting when making decisions to start/stop/pause pipelines during the FE DAI trigger. This is necessary to trigger the shared pipelines in the FE DAI trigger properly. With IPC4, the FE trigger will issue multiple pipeline state changes, and the triggers are propagated downstream to connected pipelines by the SOF driver - not the firmware. This creates a window for race conditions where an FE trigger preempts another one, which results in inconsistent pipeline states and refcounts. This patch introduces a mutex lock for the pcm trigger that guarantees that IPC4 state and resources are accessed in a serialized manner.

ASoC: SOF: Intel/IPC4: Support for external firmware libraries

2022-10-21T19:04:19+00:00

Merge series from Peter Ujfalusi : In IPC4 all DSP loadable executable is a 'library' containing modules. The main or basefw is also a library which contains multiple modules. IPC4 allows to use loadable libraries to extend the functionality of the booted basefw. This series adds support for loading external libraries in case they are needed by the loaded topology file. The libraries must be placed to a specific firmware directory (fw_lib_prefix), which is: intel/avs-lib|sof-ipc4-lib/ followed by the platform name and in case of community key use a 'community' directory. For example for upx-i11 (community key): intel/avs-lib/tgl/community is the default path. The name of the library should be the UUID of the module it contains since the library loading is going to look for the file as .bin In case there is a need to bundle multiple modules into single library, symlinks can be used to point to the file: module_boundle.bin .bin -> module_boundle.bin .bin -> module_boundle.bin .bin -> module_boundle.bin But note that in this case all modules will be loaded to the DSP since only the whole library can be loaded, not individual modules.
