PCIe bandwidth degradation in Intel® Open FPGA Stack (OFS) version 2.0.0 - PCIe bandwidth degradation in Intel® Open FPGA Stack (OFS) version 2.0.0 Description When you test Intel® Open FPGA Stack v2.0.0 PCIe bandwidth, you may find the PCIe bandwidth performance degradation as below: PCIe Server Read BW(GB/s) Write BW(GB/s) Read+Write(GB/s) IOFS V2.0.0 Gen4X16 ~16 ~16 ~26 KPI numbers Gen4x16 ~20 ~20 ~34 Resolution This problem is fixed in Intel® Open FPGA Stack v2.1.0 and above. You should upgrade your OFS version to v2.1.0 and above . What’s more, you should use the below commands to test the PCIe bandwidth: host_exerciser --mode read --cls cl_4 --continuousmode true --contmodetime 10 lpbk host_exerciser --mode write --cls cl_4 --continuousmode true --contmodetime 10 lpbk host_exerciser --mode trput --cls cl_4 --continuousmode true --contmodetime 10 lpbk Custom Fields values: ['novalue'] Troubleshooting 15011140648 False ['novalue'] ['novalue'] novalue novalue ['Agilex™ 7 FPGAs and SoCs'] ['novalue'] ['novalue'] ['novalue']
