In order to follow this flow, a new global message type has been added to prepare the DSP side of the DMA: host sends LOAD_LIBRARY_PREPARE with the dma_id DSP side sets its buffer and sets the GEN bit Host sets the RUN bit Host sends LOAD_LIBRARY with dma_id and lib_id DSP receives the library data. It is up to the platform code to use the new prepare stage message and how to handle the reply to it from the firmware, which can indicate that the message type is not supported/handled. In this case the kernel should proceed to the LOAD_LIBRARY stage assuming a single stage library loading: host sends LOAD_LIBRARY_PREPARE with the dma_id DSP replies that the message type is not supported/handled Host acknowledges the return code and sets the RUN bit Host sends LOAD_LIBRARY with dma_id and lib_id DSP receives the library data.

The firmware provides a way to handle this two stage sequencing by splitting the library loading into two stage: 1st stage: LOAD_LIBRARY_PREPARE message the lib_id is 0, used to configure the DMA on DSP side 2nd stage: LOAD_LIBRARY message both dma_id and lib_id is valid, used for the actual transfer of the library In case a firmware without support for this two stage loading is used then the second stage message will trigger the loading and the first stage will return with error, which is ignored by the kernel.
