Hi @WayneWWW

I found a topic below:

What is the actual maximum speed of Jetson AGX Xavier PCIE Ethernet?

Hi NOPUFF, Thanks for your sharing! As we have talked, due to linux kernel network stack, the PCIe virtual network not match the 10Gbps requirement. For exchanging data of “10 cameras, 1920x1080 NV12 30fps, 5 lidars”, you can base on our reference code to implement you own feature. Below patch verified Jetpack4.4 0001-gathered-all-dma-performance-test-patches.patch (11.2 KB) RP Mode DMA In the below procedure, x being the number of the root port controller whose DMA is being used for pe…

and followed the patch to modify the JP5.1.2, but the CONFIG_PCIE_TEGRA_DW_DMA_TEST=y always not effect in kernel_out/.config.
