ASoC: SOF: Add a prepare op to IPC topology widget ops

2022-04-29T12:06:05+00:00

In order to set up a pipeline with IPC4, the total memory usage for the
pipeline needs to be calculated based on the list of connected widgets.
Add a new ipc_prepare() op to struct sof_ipc_tplg_widget_ops that will be
used to calculate the memory usage for each widget in the pipelines
associated with a PCM and prepare the widget for getting set up in the
DSP. The prepare step will be used to allocate memory for the IPC
payload, assign instance ID and update the config data for the widget
based on the runtime PCM params. Once prepared, the setup step is used
to send the IPC to create the widget in the DSP.

Add an ipc_unprepare() op to unprepare the widget i.e free the memory
allocated during prepare, free the instance ID etc. This should be
invoked after the widget is freed.

A new flag "prepared" is added to struct snd_sof_widget to track the
prepared status of widgets.

Also, IPC4 requires the platform_params and the runtime PCM params in
order to prepare a widget for set up. So modify the signature of
sof_pcm_setup_connected_widgets() and sof_widget_list_setup() to accept
these as arguments.

ASoC: SOF: pcm: remove unnecessary function declaration

2022-04-29T12:06:02+00:00

sof_pcm_setup_connected_widgets() can be a static function in pcm.c. No
need to declare it in the header.

ASoC: SOF: pcm: Move the call to snd_sof_pcm_platform_hw_params()

2022-04-29T12:05:57+00:00

IPC4 requires the platform_params be passed when invoking
sof_pcm_setup_connected_widgets(). So move the call to
snd_sof_pcm_platform_hw_params() before calling
sof_pcm_setup_connected_widgets(). This has no functional impact.

sof_pcm_setup_connected_widgets will be modified in the follow up
patches to accept the platform params as an argument.

ASoC: SOF: remove const qualifier for 'struct snd_sof_dsp_ops'

2022-04-19T11:03:39+00:00

Now that we start having multiple platforms with minor variants, the
use of the const qualifier for 'dsp_ops' is starting to be
sub-optimal: the structures are copied across platforms, with only a
couple of members that differ.

This patch removes the const qualifier without any functionality
changes, and adds an optional initialization callback. In follow-up
patches, the dsp_ops will revisited for Intel HDaudio platforms, with
the differences added programmatically over a common baseline.

ASoC: SOF: Remove redundant return statements

2022-04-04T07:39:11+00:00

After the free PCM action is executed, no matter what
the return result is, it will return directly in sof_pcm_trigger.
So the return statement here is redundant.
