I have two 32G AGX dev kits and have tested the pcie epf refered to the document which is found at
https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/xavier_PCIe_endpoint_mode.html#wwpID0ESHA
They are connected with Gen4 x8.speed.
When I enable CONFIG_PCIE_TEGRA_DW_DMA_TEST
and test dma read/write, how much throughput expected?
Do you have pcie performance measured on AGX dev kit?

We expect to observe around 107 Gbps

Thanks vidyas.
In PCIE DMA, Read throughput can be lower than write throughput.
How different speed in AGX?
