From 1221a4746769f70231beab4db8da1c937e60340c Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Tue, 11 Jul 2017 13:56:20 +1000 Subject: memory/iommu: introduce IOMMUMemoryRegionClass This finishes QOM'fication of IOMMUMemoryRegion by introducing a IOMMUMemoryRegionClass. This also provides a fastpath analog for IOMMU_MEMORY_REGION_GET_CLASS(). This makes IOMMUMemoryRegion an abstract class.
