Function Documentation

mod_data_create()

struct smart_amp_mod_data_base * mod_data_create

(

const struct comp_dev *

dev

)

Creates the self-declared model data struct.

Refer to "struct smart_amp_mod_data_base" for details of declaration. Args: dev - the comp_dev object for logger tracing use only. Returns: The pointer of "smart_amp_mod_data_base" which is the leading member in the created model data struct.

smart_amp_get_sink_func()

smart_amp_sink_func smart_amp_get_sink_func	(	uint16_t	comp_fmt,
		uint16_t	mod_fmt
	)

Retrieve sink processing callback matching component and module PCM formats.

Parameters

comp_fmt	Component stream frame format.
mod_fmt	Processing module internal frame format.

Returns

Sink processing function pointer, or NULL if no match found.

smart_amp_get_src_func()

smart_amp_src_func smart_amp_get_src_func	(	uint16_t	comp_fmt,
		uint16_t	mod_fmt
	)

Retrieve source processing callback matching component and module PCM formats.

Parameters

comp_fmt	Component stream frame format.
mod_fmt	Processing module internal frame format.

Returns

Source processing function pointer, or NULL if no match found.
