Data Fields
uint64_t	stream_start_offset
	Stream start offset (LPIB) reported by mixin module allocated on pipeline attached to Host Output Gateway when first data is being mixed to mixout module.

Detailed Description

Pipeline DMA tracking registers in Mailbox Window 0.

Field Documentation

stream_end_offset

uint64_t ipc4_pipeline_registers::stream_end_offset

Stream end offset (LPIB) reported by mixin module allocated on pipeline attached to Host Output Gateway during transition from RUNNING to PAUSED.

When data is not mixed (right after creation/after reset) value "(uint64_t)-1" is reported. When first data is mixed then value "0" is reported. In number of bytes.

stream_start_offset

uint64_t ipc4_pipeline_registers::stream_start_offset

Stream start offset (LPIB) reported by mixin module allocated on pipeline attached to Host Output Gateway when first data is being mixed to mixout module.

When data is not mixed (right after creation/after reset) value "(uint64_t)-1" is reported. In number of bytes.
