Subject:[Xen-devel] Is machine_to_phys_mapping a 4MB 'superpage'?

hi,

The machine_to_phys_mapping table is mapped permanently at 0xFC000000 (on x86-32). I would like to experiment with letting the domU map it at other locations in its virtual address space, but I suppose that for performance it is mapped as a 4MB 'super' page, and as such needs special treatment, is this correct?

Thanks, Jacob
