[Xen-devel] [PATCH] VT-d: remove Xen and tboot range from dom0''s VT-d table
This a step forward to fix the security hole introduced by dom0''s 1:1 mapping VT-d table: remove the critical code and data from it. The more flexible solution is to update dom0''s VT-d table on demand as what will be done for other PV domains. However, there could bring a performance issue even with software optimization. Iotlb flush of some hardware is time-consuming.
