Hi, This patches series add a range operation for the intel iommu. IOTLBs flushes can be really expensive on some hardware, so we need a range interface to only do the flush once, instead of for each pages. 01: intel_iommu_set_entry 02: iommu_export_set_entry 03: xc_iommu_map_batch Thanks, Jean _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
