[Xen-devel] Fix print_vtd_entries walk VTd mapping table
DMA request to above guest physical memory will cause VTd fault, in which print_vtd_entries() tries to walk VTd mapping table. However, during walking, current Xen code didn''t check if the PTE is valid and may access to invalid memory address.
