    User programmable DMA controller in the system with  Xeon E3-1275v3 and  C226 PCH?


      We are using Xeon E3-1275v3 and  C226 PCH on our board. I am aware that this system does not support I/OAT or NetDMA.


      Is there any user programmable DMA controller?


      We want to perform DMA transfers from the main memory (source) to PCIe devices (destination).

      Note: PCIe devices do not have DMA controller. PCIe device can be either PCIe BAR in endpoint or multicast BAR residing inside PCIe switch.
