Indeed, I have come across RoCE, and support seems to be quite active on Debian. I was looking at QLogic hardware for this, and whilst I know that firmware for such stuff is really difficult to find, I’m fine with just FOSS support on Debian
I think I misunderstood what exactly you wanted. I don’t think you’re getting remote GPU passthrough to virtual machines over ROCE without an absolute fuckton of custom work. The only people who can probably do this are Google or Microsoft. And they probably just use proprietary Nvidia implementations.
Well, I’m not a systems engineer, so I probably don’t understand the scale of something like this.
With that said, is it really hard to slap TCP/IP on top of SR-IOV? That is literally what I wanted to know, and I thought RDMA could do that. Can it not?

I believe what you’re looking for is ROCE: https://en.wikipedia.org/wiki/RDMA_over_Converged_Ethernet
But, I don’t know if there’s any FOSS/libre/etc hardware for it.
So it is RDMA.
