From 1b53ecd909bc59bb5f54892a5cbb8721a3467ede Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Mon, 12 Aug 2019 07:23:34 +0200 Subject: memory: Fix type of IOMMUMemoryRegionClass member @parent_class MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit TYPE_IOMMU_MEMORY_REGION is a direct subtype of TYPE_MEMORY_REGION. Its instance struct is IOMMUMemoryRegion, and its first member is a MemoryRegion. Correct. Its class struct is IOMMUMemoryRegionClass, and its first member is a DeviceClass. Wrong. Messed up when commit 1221a474676 introduced the QOM type. It even included hw/qdev-core.h just for that. TYPE_MEMORY_REGION doesn't bother to define a class struct. This is fine, it simply defaults to its super-type TYPE_OBJECT's class struct ObjectClass. Changing IOMMUMemoryRegionClass's first member's type to ObjectClass would be a minimal fix, if a bit brittle: if TYPE_MEMORY_REGION ever acquired own class struct, we'd have to update IOMMUMemoryRegionClass to use it. Fix it the clean and robust way instead: give TYPE_MEMORY_REGION its own class struct MemoryRegionClass now, and use it for IOMMUMemoryRegionClass's first member. Revert the include of hw/qdev-core.h, and fix the few files that have come to rely on it.
