I think you should propose a concrete API and give examples of how userspace would be using it; these abstract discussions aren't really coming together in my head. Can the kernel just set up the initial routing mapping as 1:1 so userspace can ignore the pointless extra level of indirection? thanks -- PMM _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
