Re: [Xen-devel] Booting Xen 3.4 with iommu=1 causes boot to hang
Hi Keir : "iommu_inclusive_mapping" ? I will try . Did the xen-3.4.0 version have much more features to surpport graphic pass through? I am working on the PCIE graphic pass through test. Could this work done without modifing the source code? Just throuhing some configuriation works .

There are plenty of broken BIOSes out there that don't correctly support
VT-d. Try adding iommu_inclusive_mapping as an extra Xen boot parameter --
this workaround is often successful.
