Intel FPGA PCIe driver not working on Xavier AGX


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?

You can try it first. Without log, we don’t know what happened.
