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?
