Typedefs
typedef ssize_t(*	probe_logging_hook_t) (uint8_t *buffer, size_t length)
	Callback hook invoked when a chunk of probe logging data is ready.

Functions
void	probe_logging_init (probe_logging_hook_t hook)
	Initialize the probe logging backend.
int	probe_init (const struct probe_dma *extraction_probe_dma)
	Initialize the audio probes subsystem.
int	probe_deinit (void)
	Deinitialize the probes subsystem and detach extraction DMA.
int	probe_dma_add (uint32_t count, const struct probe_dma *probe_dma)
	Configure injection DMA channels for inserting audio streams into pipelines.
int	probe_dma_info (struct sof_ipc_probe_info_params *data, uint32_t max_size)
	Query configuration information for active injection DMAs.
int	probe_dma_remove (uint32_t count, const uint32_t *stream_tag)
	Disconnect and remove active injection DMA channels.
int	probe_point_add (uint32_t count, const struct probe_point *probe)
	Attach probe points to audio pipeline buffers for stream tap/injection.
int	probe_point_info (struct sof_ipc_probe_info_params *data, uint32_t max_size)
	Query configuration of currently active probe points.
int	probe_point_remove (uint32_t count, const uint32_t *buffer_id)
	Detach and remove probe points from pipeline buffers.
static struct probe_pdata *	probe_get (void)
	Retrieve global probes private data context from SOF runtime.
