From 1b3bf13890fd849b2628ca8c059f8d63c74b9572 Mon Sep 17 00:00:00 2001 From: Jean-Philippe Brucker Date: Tue, 26 Oct 2021 19:20:22 +0100 Subject: hw/i386/pc: Move IOMMU singleton into PCMachineState We're about to support a third vIOMMU for x86, virtio-iommu which doesn't inherit X86IOMMUState. Move the IOMMU singleton into PCMachineState, so it can be shared between all three vIOMMUs. The x86_iommu_get_default() helper is still needed by KVM and IOAPIC to fetch the default IRQ-remapping IOMMU. Since virtio-iommu doesn't support IRQ remapping, this interface doesn't need to change for the moment. We could later replace X86IOMMUState with an "IRQ remapping IOMMU" interface if necessary.
