DirectGMA - PCIe topology requirements

Jump to solution

Dear AMD Community,

From what I know regarding the PCIe protocol organization, a direct peer-to-peer communication between endpoints is possible only in the presence of an intermediate PCIe switch. It could either be a discrete IC or the functionality could be integrated inside the root complex as well. Correct me if I'm wrong...

Now, because I need a peer-to-peer DirectGMA between a Kintex 7 and Radeon Pro, may you please advise what requirement I have to meet from the point of view of motherboard and chipset selection - in order to get a native PCIe switching functionality? 

Note: I won't mind if you move the thread to another section if you do not think it is relevant. The "FirePro Development" is the only section I am currently whitelisted for, that is the reason I am posting it here.
