| H A D | intel_iommu_internal.h | diff 651e4cefeee8e388919e51f4e299033ab2a8b87d Thu Jul 14 00:56:22 CDT 2016 Peter Xu <peterx@redhat.com> intel_iommu: Add support for PCI MSI remap
This patch enables interrupt remapping for PCI devices.
To play the trick, one memory region "iommu_ir" is added as child region
of the original iommu memory region, covering range 0xfeeXXXXX (which is
the address range for APIC). All the writes to this range will be taken
as MSI, and translation is carried out only when IR is enabled.
Idea suggested by Paolo Bonzini.
