Does Jetson PCIe RC support Resize BAR?

Hi
We want to use Jetson Orin with RTX A4000 GPU plus FPGA, using rdma.
Since we need to use pin GPU memory. Its size is related to BAR1 size. We need to pin more memory. Does Jetson support adjustment? How should it be adjusted?

To connect a dGPU via PCIe is not able to work with Jetson Orin, I will suggest to use IGX devkit, you can refer to IGX | Industrial-Grade Edge AI platform | NVIDIA

I’d love to use it for validation.
Aren’t NVIDIA IGX Orin and Jetson AGX Orin the same module?

Does its PCIe support Resize BAR?

They are not the same module, not compatible.
