Hi,

Refer to

  1. Tegra virtual Ethernet driver over PCIe
    kernel/nvidia/drivers/pci/endpoint/functions/pci-epf-tegra-vnet.c → EP driver
    kernel/nvidia/drivers/net/ethernet/nvidia/pcie/tegra_vnet.c → EP client driver in host

  2. PCIe DMA test driver which has simple directed test for both direct and linked list mode.
    kernel/nvidia/drivers/misc/tegra-pcie-ep-mem.c → EP client driver

  3. Refer to PCIE_DMA registers in PCIe IATU section of Xavier TRM.

Thanks,
Manikanta
