Hi, When dom0 boots it prints out a couple of lines like these: Xen p2m: assign p2m table of [0x0000003000000000, 0x0000003024000000) Xen p2m: to [0x000001b040000000, 0x000001b043ffc000) (65536 KBytes) I am trying to figure out where the addresses in the first line originate from. They are obviously picked by Xen and provided to dom0 somehow, but how and where? I see dom0 finds it via allocate_resource() in the resource tree, but it's not obvious to me where we export this resource to dom0 from Xen. Just hoping somebody knew where these addresses where assigned? Cheers, Jes _______________________________________________ Xen-ia64-devel mailing list Xen-ia64-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-ia64-devel |
