Thread-topic: [Xen-devel] [PATCH] [VTD] Enable pass-through translation for Dom0
If pass-through field in extended capability register is set, set
pass-through translation type for Dom0, that means DMA requests with
Untranslated addresses are
processed as pass-through in Dom0, needn't translate DMA requests
through a multi-level page-table.
