Hello, We have a custom board with a Xavier NX + PCIe Switch + FPGA. The Jetson is the PCIe root. All endpoints are capable of >= 256 bytes and this can be confirmed through lspci as well as the switch configuration software. I mostly do FPGA work, so I don’t work with embedded Linux much, but t…

You can download BSP source. Jetson Linux R32.6.1 Release Page NVIDIA® Jetson™ Linux Driver Package (L4T) is the board support package for Jetson. It includes Linux Kernel 4.9, bootloader, NVIDIA drivers, flashing utilities, sample filesystem based on Ubuntu 18.04, and more for the Jets…

You can download BSP source.

Decompress public_sources.tbz2 and then kernel_src.tbz2

The PCI source code path as it
=> /Linux_for_Tegra/source/public/kernel/nvidia/drivers/pci/dwc/pcie-tegra.c

You can check MPS as follows :
