const char* dev_name¶

Unique device name.

Definition at line 286 of file rte_dmadev.h.

uint64_t dev_capa¶

Device capabilities (RTE_DMA_CAPA_*).

Definition at line 288 of file rte_dmadev.h.

uint16_t max_vchans¶

Maximum number of virtual DMA channels supported.

Definition at line 290 of file rte_dmadev.h.

uint16_t max_desc¶

Maximum allowed number of virtual DMA channel descriptors.

Definition at line 292 of file rte_dmadev.h.

uint16_t min_desc¶

Minimum allowed number of virtual DMA channel descriptors.

Definition at line 294 of file rte_dmadev.h.

uint16_t max_sges¶

Maximum number of source or destination scatter-gather entry supported. If the device does not support COPY_SG capability, this value can be zero. If the device supports COPY_SG capability, then rte_dma_copy_sg() parameter nb_src/nb_dst should not exceed this value.

Definition at line 302 of file rte_dmadev.h.

int16_t numa_node¶

NUMA node connection, -1 if unknown.

Definition at line 304 of file rte_dmadev.h.

uint16_t nb_vchans¶

Number of virtual DMA channel configured.

Definition at line 306 of file rte_dmadev.h.

uint16_t nb_priorities¶

Number of priority levels (must be > 1) if priority scheduling is supported, 0 otherwise.

Definition at line 310 of file rte_dmadev.h.
