ASoC: SOF: topology: Add new token for dynamic pipeline

2021-10-01T19:48:22Z

Today, we set up all widgets required for all PCM streams at the time of topology parsing even if they are not used. An optimization would be to only set up the widgets required for currently active PCM streams. This would give the FW the opportunity to power gate unused memory blocks, thereby saving power. For dynamic pipelines, the widgets in the connected DAPM path for each PCM will need to be set up at runtime. This patch introduces a new token, DYNAMIC_PIPELINE, for scheduler type widgets that indicate whether a pipeline should be set up statically during topology load or at runtime when the PCM is opened. Introduce a new field called dynamic_pipeline_widget in struct snd_sof_widget to save the value of the parsed token. The token is set only for the pipeline (scheduler type) widget and must be propagated to all widgets in the same pipeline during topology load. Introduce another field called pipe_widget in struct snd_sof_widget that saves the pointer to the scheduler widget with the same pipeline ID as that of the widget. This field is populated when the pipeline completion callback is invoked during topology loading.

ASoC: SOF: support topology components on secondary cores

2020-09-04T09:12:22Z

Currently SOF supports running pipelines on secondary DSP cores in a limited way. This patch represents the next step in SOF multi-core DSP support, it adds checks for core ID to individual topology components. It takes care to power up all the requested cores. More advanced DSP core power management should be added in the future.

2020-04-15T23:23:17Z

FW interface for HDA DAI parameters was extended with information on sampling rate and channel count in version 3.16. Align kernel header with the FW change. This change is backwards compatible. Old firmware will ignore the values.
