From 18fd779a41eff52b597bd2d327194f98a83de4af Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Fri, 11 Jul 2014 14:19:26 +0800 Subject: [PATCH] iommu/vt-d: Use correct domain id to flush virtual machine domains For virtual machine domains, domain->id is a virtual id, and the real domain id written into context entry is dynamically allocated. So use the real domain id instead of domain->id when flushing iotlbs for virtual machine domains.
