Memory to memory DMA copy capability of In Xeon E-2276me

[heleboy]

Dear,

I checked all Intel Xeon E 2200 series documentation, I couldn't find any DMA transaction resource in SoC to/from PCIe FPGA device memory.

If I am wrong, could you please guide me on how to find it? In which document? Which resource?

Best regards

Dear CarlosAM_Intel,

The board is a custom board designed by a team, in which I am involved as a subcontractor to develop Fpga Windows Driver. If it is still needed I can provide customer details by e-mail. I dont want to give customer details in an online open forum. Xeon E-2200me is used.

Windows can work on board successfully. Our Fpga driver can successfully detect Fpga device, and can write/read 1/2/4/8/32 bytes to/from Fpga device. Now I am looking for higher performance ways. I checked EDS documents. As I mentioned, I couldnt find any convenient DMA resource.

Can you please help me? Is there any resource available to make DMA memory-to-memory transaction?

Best regards
