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. Signed-off-by: Yang, Xiaowei <xiaowei.yang@xxxxxxxxx> Thanks, Xiaowei Attachment:
