Redirect GUI through PCIe interface: GPUDirect vs DRM

Hi,
I wish to redirect all GPU output through a PCIe interface to an external device instead of DP.

Here I asked regarding general GPU data redirection:

My question now is regarding redirecting the GUI frames. I know the GPU draws the GUI and outputs the frames via DP.

If I wish to output the GUI frames via PCIe interface instead DP, should I use GPUDirect RDMA as well or this case requires modifying the DRM Module and X11/wayland servers?

Thanks

Hi,

GPU direct usually requires an FPGA connection.
Please see below for info:

Thanks.

Thank you for your help. I’ll try using this demo.
