rte_event_dma_adapter_runtime_params - Man Page

uint32_t max_nb
uint32_t rsvd [15]

The adapter can return early if it has processed at least max_nb DMA ops​. This isn't treated as a requirement; batching may cause the adapter to process more than max_nb DMA ops​.

Callback function passed to rte_event_dma_adapter_create_ext() configures the adapter with default value of max_nb​. rte_event_dma_adapter_runtime_params_set() allows to re-configure max_nb during runtime (after adding at least one queue pair)

This is valid for the devices without RTE_EVENT_DMA_ADAPTER_CAP_INTERNAL_PORT_OP_FWD or RTE_EVENT_DMA_ADAPTER_CAP_INTERNAL_PORT_OP_NEW capability​.
