PCIe Interfaces - can all five be run as Root simultaneously with DMA?


Is it practical to run all five PCIe interfaces (x8, x4, x2, x1, x1) as the root port? Is there a separate DMA for each so the processor isn’t doing any of the data moving?

Thank you for your time,


Yes, all five PCIe controllers can be used simultaneously and they each have DMA. And their default mode is root port.
