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.
