Field Documentation

buffer_id

probe_point_id_t probe_point::buffer_id

ID of pipeline buffer to which probe is attached.

ID of module buffer/pin to which probe is attached.

purpose

uint32_t probe_point::purpose

Probe role (PROBE_PURPOSE_*)

Extraction or injection (PROBE_PURPOSE_xxx).

stream_tag

uint32_t probe_point::stream_tag

Stream tag of DMA for injection; ignored on extraction request and populated on reply.

Stream tag of DMA providing injection data (for injection probes); ignored for extraction where firmware automatically binds the configured extraction DMA tag.
