AFAICS, FSA is a sw interface to underlying hw. Assuming intel buys into - or is arm twisted into buying into - the FSA premise, both AMD and Intel could do proprietary PCIe coherency extensions, implement FSA and still cut nv out of the picture.
IOW, implementing FSA does not require a standardized coherency-over-PCIe protocol.
The views presented here are my own and not my employer's.
