Intel posts an RFC for DRM Fabric, a vendor-neutral topology layer for GPU and accelerator scale-up interconnects

Sources: Phoronix report, discussion
Summary: Intel sent an RFC series proposing DRM Fabric, a vendor-neutral kernel layer that exposes scale-up interconnect topology for GPUs and accelerators through a Generic Netlink uAPI. The RFC ships no production provider implementation and records direct adjacency only.
Why it matters: Scale-up interconnect topology has been per-vendor, and this proposes one Generic Netlink uAPI over it, though the RFC ships no production provider implementation and records direct adjacency only.
Follow-up: Maintainer response on the mailing list, and whether a vendor commits a production provider.
