Intel FPGA PCIe driver not working on Xavier AGX

Hi,

I try to connect Intel Stratix10MX dev kit to Xavier AGX through PCIe. the FPGA design and Intel PCIe driver works on X86_64 CPU with CentOS 7.0. I installed the driver and compile the application software on Xavier AGX and didn’t encounter any problem. When I run the test problem, the PCIe mem read/write worked but DMA read failed. The data read back through DMA read is not right. I saw some thread in this forum talked about disable SMMU for Xilinx FPGA PCIe design. is it applicable to Intel Stratix10MX FPGA?

regards,
