Description
Due to limitation in support in OpenCL Board Support Package (BSP), Intel® Stratix® 10 GX FPGA Development Kit can only support up to PCIe gen3x8 for OpenCL, although its PCIe hard IP can support PCIe gen3x16.
Resolution
To work around this problem, you can create a custom BSP for the Intel® Stratix® 10 GX FPGA Development Kit.
There is no current plan to add PCIe Gen3x16 to the OpenCL Board Support Package (BSP) for the Intel® Stratix® 10 GX FPGA Development Kit.
