Hello, The following series implement a workaround for missing RMRR entries for a PVH Dom0. It's based on the iommu_inclusive_mapping VTd option.
The PVH workaround identity maps all regions marked as reserved in the memory map. Note that this workaround is enabled by default on Intel hardware. It's also available to AMD hardware, although it's disabled by default in that case. The series can be found at: git://xenbits.xen.org/people/royger/xen.git iommu_inclusive_v2 Thanks, Roger.
