This is an embarrassing bug. The machine address we're trying to map is 0x42c000000. That is above 16GB, because the machine has 16GB of RAM plus a 2GB IO hole, meaning addresses up to 18GB are actually possible. However, the flag we use to indicate a foreign mapping is the 16GB bit, 0x400000000. (We unfortunately did not start with bits at the top of the address space.) Aside from having Xen pick another bit, we will need a Linux patch because that bit is hardcoded in some assembly. -- Hollis Blanchard IBM Linux Technology Center _______________________________________________ Xen-ppc-devel mailing list Xen-ppc-devel@lists.xensource.com http://lists.xensource.com/xen-ppc-devel
