struct rte_mempool* op_mp¶

Mempool from which op is allocated.

Definition at line 1063 of file rte_dmadev.h.

enum rte_dma_status_code status¶

Status code for this operation.

Definition at line 1065 of file rte_dmadev.h.

uint32_t rsvd¶

Reserved for future use.

Definition at line 1067 of file rte_dmadev.h.

uint64_t impl_opaque[2]¶

Implementation-specific opaque data. A DMA device implementation use this field to hold implementation-specific values to share between dequeue and enqueue operations. The application should not modify this field.

uint64_t user_meta¶

Memory to store user specific metadata. The DMA device implementation should not modify this area.

Definition at line 1078 of file rte_dmadev.h.

uint64_t event_meta¶

Event metadata of DMA completion event. Used when RTE_EVENT_DMA_ADAPTER_CAP_INTERNAL_PORT_VCHAN_EV_BIND is not supported in OP_NEW mode.

See also

Used when RTE_EVENT_DMA_ADAPTER_CAP_INTERNAL_PORT_OP_FWD is not supported in OP_FWD mode.
