Matt:
Dan mentioned that you had VNIF work almost done without PMT
table support for dom0, Can you share the idea with us?
Usually VNIF swap page between dom0 and domU so that network
package copy (between dom0 native driver and domU frontend driver) can
be avoided and thus achieve high performance. With this swap, we can no
longer assume dom0 gpn=mfn. So what did you ever propose to port VNIF
without PMT table?
Thanks a lot, eddie
