| 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.
