Re: [Xen-devel] [PATCH 03/11] [XEN] NUMA guest tools interface

The patch adds hypercall interfaces to get/set the virtual numa layout

I don't see the need for introducing this many new interfaces. I
couldn't find a reference for the nodemap information (mfn_to_nid) to be
actually used somewhere, is there any missing part or was it just for
the sake of completeness?
Beside that, cpu_to_node is already in physinfo, and via xc_availheap
(which takes a node parameter) you can query the amount of free memory
per node. I think that is all we need to know about the host's NUMA
topology, but correct me if I am wrong.
(OK, the distance information is missing...)
From a design point of view I would avoid exporting so many host
machine information to Dom0 unless we really need it.
Regards,
Andre.
