ASoC: SOF: pipelines: Harmonize all functions to use struct snd_sof_dev

2021-10-07T14:45:45+00:00

First thing the pipelines function which have "struct device *dev" as
parameter do is:
struct snd_sof_dev *sdev = dev_get_drvdata(dev);

and in all cases the passed dev is actually coming from sdev->dev.

Skip this steps and pass directly the sdev to all pipelines related
functions as few of them already does this.

ASoC: SOF: Intel: hda: add new flags for DAI_CONFIG

2021-10-05T12:08:12+00:00

The DAI_CONFIG is used for both hw_params and hw_free. Use flags to
specify what stage the configuration applies to.

the DAI_CONFIG IPC may be sent also during the widget setup so each
flag is cleared after the IPC to restore the state.

ASoC: SOF: topology: Add kernel parameter for topology verification

2021-10-01T19:48:31+00:00

Add a kernel debug flag to enable a one-shot topology
verification for all pipelines including the dynamic
ones. If the debug flag is set, all the topology
component loading will be verified during the complete
callback.

ASoC: SOF: Add support for dynamic pipelines

2021-10-01T19:48:30+00:00

Add support for dynamic pipelines by modifying the PCM
hw_params ioctl implementation to determine the widgets
required for a PCM stream by querying the list of
connected DAPM widgets. This list is saved as part of
snd_sof_pcm_stream struct and will be used to setup the widgets.

The sof_widget_list_setup/free routines setup and free connected
DAPM widgets when a PCM is opened/closed. These routines accept
a list of connected DAPM widgets as input and determine the SOF
widgets, their corresponding pipeline widgets and connections
between them that need to be setup before the PCM is triggered.

Please note that the dynamic pipeline feature will only be enabled
for those pipelines whose dynamic_pipeline_widget flag is set in
topologies. Add a new token called SOF_TKN_SCHED_DYNAMIC_PIPELINE
that when set in topology will be applied to the
dynamic_pipeline_widget flag of the pipeline widget.

ASoC: SOF: Intel: hda: make sure DAI widget is set up before IPC

2021-10-01T19:48:29+00:00

With the implementation of the dynamic pipeline feature, widgets
will only be setup when a PCM is opened during the
hw_params ioctl. The BE hw_params callback is responsible for
sending the DAI_CONFIG for the DAI widgets in the DSP.
With dynamic pipelines, the DAI widgets will need to set up
first before sending the DAI_CONFIG IPC in the BE hw_params.

Update the BE hw_params/hw_free callbacks for all ALH, HDA and SSP
DAIs to set up/free the DAI widget before/after DAI_CONFIG IPC.

ASoC: SOF: Introduce widget use_count

2021-10-01T19:48:28+00:00

Add a new field, use_count to struct snd_sof_widget to keep track
of the usage count for each widget. Since widgets can belong to
multiple pipelines, this field will ensure that the widget
is setup only when the first pipeline that needs it is started
and freed when the last pipeline that needs it is stopped. There is
no need to protect the widget use_count access as the core already
handles mutual exclusion at the PCM level.
Add a new helper sof_widget_free() to handle freeing the SOF
widgets and export the sof_widget_setup/free() functions.

ASoC: SOF: Don't set up widgets during topology parsing

2021-10-01T19:48:27+00:00

In preparation for supporting dynamic pipelines, move the
widget setup, DAI config IPCs to the complete callback
during topology loading. For current topology where all
the pipelines are static, all the pipelines will be set up
during complete. For topologies with dynamic and static pipelines,
this will enable setting up only the static ones  during
topology loading. Reuse the sof_restore_pipelines() function for
this purpose and rename it to sof_set_up_pipelines().

2021-10-01T19:48:24+00:00

Add two new fields to save the source widget and sink widget
pointers in struct snd_sof_route to make it easier to look up
routes by source/sink widget. Also, add a flag to indicate
if the route has been set up in the DSP. These will be used
when the dynamic pipeline feature is implemented and routes
will have to be set up at run time.

Also, add a new sof_tear_down_pipelines() callback, that will
used to reset the set up status for all routes during suspend.
