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

[SZigi]

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.

Hi szigic,

This is a very good question but I would recommend you posting it on Intel® Developer Zone. Here you have the link:
