100 GbE on a Jetson AGX Orin dev kit


What is our best chance to use a 100 GbE NIC (with DPDK) in a Jetson AGX Orin dev kit? So far, we tried:

  • an NVIDIA MCX653105A-ECAT: not detected with lspci after booting (not even after echo 1 >/sys/bus/pci/rescan).
  • an Intel e810: works fine with the ice driver, but not with DPDK, as the vfio_pci driver complains that IOMMU group 12 is not viable
  • a QNAP QXG-25G2SF-CX6: works (also with DPDK), but needs multiple boot attempts to be detected, and is only dual 25 GbE.
    We use JetPack 5.0.2 with the Jetson Linux 35.1 BSP. Solutions as described in SOLUTION/TUTORIAL: Jetson ORIN Enabling PCIE power and Jetson AGX Orin board not able to enumerate FPGA PCIe card (Latest kernel 35.1.0) did not solve our problems. The dmesg output is attached. Any help is more than welcome!

Sorry for the late response, is this still an issue to support? Thanks

Yes, we still did not find a way to make any type of 100 GbE NIC work in the AGX Orin, either because the NIC is not detected at boot time, or because the vfio_pci driver used by DPDK does not work (we need DPDK to avoid prohibitive OS overhead). We use the Orin’s tensor cores for signal processing, and they are so fast that we think that it can handle close to 100 Gb/s of input in less than 75 Watt (including NIC), which would set a new milestone in energy efficiency. But we need a working 100 GbE NIC for that.

Hey John, I was in a very similar situation. My ConnectX-5 EX was not recognized by the Jetson AGX Orin. The solution was to update the ConnectX FW, PXE, and UEFI. After the update was made, the board is now recognized by the Jetson.

Great; I will give it a try. I assume that you did the update in another machine that did recognize the card?

Yes, the update was made on an X86 desktop. The card was connected on a PCIe 3.0 x8 (in x16) slot (not important but worth mentioning).

Updating the firmware solved the problem with our ConnextX-6 NIC too. The NIC originated from a Lenovo server, and it turned out that Lenovo installed its own firmware. The NIC is now properly detected by the Orin. Thanks for the tip; it was really helpful!
