Hi Gregory,

Sorry for the late reply.

I took a look at the exclusive-node RFC. The approach looks useful for
device-backed private memory without a firmware-described NUMA node.
Thanks for the pointer.

We are currently looking into the private-node and CRAM design as a
whole. I noticed that CRAM was not included with the v5 series, and saw
that others were also interested in a v5 version.

If you already have a CRAM branch or patches based on v5, even if they
are still work in progress, would you mind sharing them? It would be
very helpful for us to continue testing the overall design.

Thanks,
Qiqi
