I want to use XDMA on Radeon Pro Duo. What is the API?
More context: I want to send data between GPUs over PCI inside one computer (under one PCI root complex), without going through the main memory of the compuer. NVIDIA cards call this GPUDirect Peer-to-Peer (P2P). However, Radeon Pro Duo uses OpenCL, and there is an extension
but is this extension supported on Radeon Pro Duo? If not, is there some other way to use XDMA?
AFAIK, at present, this extension (and also DirectGMA) is only available on selected FirePro products.
