I have a successful project using my U280 card through Vitis Accel, which is using the XDMA through PCIe to transfer data from my host software to the kernel.
My next goal is to use an RDMA through the 100 Gb Ethernet port on the U280, essentially to do the same thing. Although I only see reference designs of the ERNIC IPs for the U200 and U250, and furthermore those designs use IPs labeled specifically for 'RDMA' but when using the U280 in the project, there are no such IPs available.
So is there any formal support to use RDMA on the U280? If not, then the only other solution I see is using a Microblaze to be the middle man between the 100 Gb Ethernet port and my PL. Or are there other approaches to this?
