Enable support for the AMD Queue-based DMA subsystem. The primary
|
||
|
|
mechanism to transfer data using the QDMA is for the QDMA engine to
|
||
|
|
operate on instructions (descriptors) provided by the host operating
|
||
|
|
system. Using the descriptors, the QDMA can move data in either the
|
||
|
|
Host to Card (H2C) direction or the Card to Host (C2H) direction.
