Field Documentation

◆ flags

uint64_t flags

Flags related to the operation.

See also: RTE_DMA_OP_FLAG_*

◆ op_mp

struct rte_mempool* op_mp

Mempool from which op is allocated.

Definition at line 164 of file rte_event_dma_adapter.h.

◆ status

enum rte_dma_status_code status

Status code for this operation.

Definition at line 166 of file rte_event_dma_adapter.h.

◆ rsvd

uint32_t rsvd

Reserved for future use.

Definition at line 168 of file rte_event_dma_adapter.h.

◆ impl_opaque

uint64_t impl_opaque[2]

Implementation-specific opaque data. An 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.

Definition at line 170 of file rte_event_dma_adapter.h.

◆ user_meta

uint64_t user_meta

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

Definition at line 177 of file rte_event_dma_adapter.h.

◆ event_meta

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: rte_event_dma_adapter_mode::RTE_EVENT_DMA_ADAPTER_OP_NEW; RTE_EVENT_DMA_ADAPTER_CAP_INTERNAL_PORT_VCHAN_EV_BIND

Used when RTE_EVENT_DMA_ADAPTER_CAP_INTERNAL_PORT_OP_FWD is not supported in OP_FWD mode.

Definition at line 181 of file rte_event_dma_adapter.h.

◆ dma_dev_id

int16_t dma_dev_id

DMA device ID to be used with OP_FORWARD mode.

See also: rte_event_dma_adapter_mode::RTE_EVENT_DMA_ADAPTER_OP_FORWARD

Definition at line 195 of file rte_event_dma_adapter.h.

◆ vchan

uint16_t vchan

DMA vchan ID to be used with OP_FORWARD mode

See also: rte_event_dma_adapter_mode::RTE_EVENT_DMA_ADAPTER_OP_FORWARD

Definition at line 199 of file rte_event_dma_adapter.h.

◆ nb_src

uint16_t nb_src

Number of source segments.

Definition at line 203 of file rte_event_dma_adapter.h.

◆ nb_dst

uint16_t nb_dst

Number of destination segments.

Definition at line 205 of file rte_event_dma_adapter.h.

◆ src_dst_seg

struct rte_dma_sge src_dst_seg[0]

Source and destination segments.
