rte_dma_inter_domain_param - Man Page
Synopsis
#include <rte_dmadev.h>
Data Fields
enum rte_dma_inter_domain_type type
uint16_t src_handler
uint16_t dst_handler
uint64_t reserved [2]
Detailed Description
Parameters for inter-process or inter-OS DMA transfers.
- Warning
EXPERIMENTAL: this API may change without prior notice.
This structure defines the parameters required to perform DMA transfers across different domains, such as between processes or operating systems. It includes the domain type and handler identifiers for both the source and destination domains.
When domain type is RTE_DMA_INTER_DOMAIN_NONE, both source and destination handlers are invalid, DMA operation is confined within the local process.
For DMA transfers between the local process or OS domain to another process or OS domain, valid source and destination handlers must be provided.
