| Thread-topic: | [Xen-devel] [PATCH] [VTD] Add a command line param to enable/disable pass-through feature |
Taking security into accout, it's not suitable to bypass VT-d translation for Dom0 by default when the pass-through field in extended capability register is set. This feature is for people/usages who are not overly worried about security/isolation, but want better performance. This patch adds a command line param that controls if it's enabled or disabled.
