Hi seanlj,

 

I hope, that every new chipset is compatible with traditional memory transactions :-) So you need to use standard memory write/read TLPs (not IO TLPs). And for direct communication from FPGA to other peripherial card (GPU) you need to use correct TLP addressing based on PCI ID identification.
