Enabling CONFIG_PCIE_TEGRA_DW_DMA_TEST jetson xavior

Currently we are having a setup like one jetson xavier acts as RC and another jetson xavior acts as Endpoint.

In that, I want to try the dma test code provided in the nvidia/drivers/pci/dwc/pcie-tegra.c.
I understood from the code we can test the dma engine using the debugfs from userspace
But when i try to enable CONFIG_PCIE_TEGRA_DW_DMA_TEST thru make menuconfig command, i couldn’t found CONFIG_PCIE_TEGRA_DW_DMA_TEST options.

When i try to search

but inside bus support feature there is no Nvidia Tegra PCIe host controller option.

Can you please help us?

Rather ask this in the Jetson Xavier forums:
This forum is mainly about the x86 graphics drivers so rarely anyone knows about the arm platforms.
