3.1 EDK OPB_Ethernet (EMAC) - Does this core support DMA without scatter/gather?

説明

General Description: 

Does this core support DMA without scatter/gather?

ソリューション

The opb_ethernet core has a parameter named C_DMA_PRESENT. You can check the data sheet located under <Your EDK Install>/doc for the value of this parameter. A value of three indicates that the core has scatter-gather DMA, and a value of two indicates that the core has simple DMA (no scatter/gather).
