Subject: [RFC 6/7] hw/vfio: Remove memory_region_iommu_set_iova_ranges() call
Date: Wed, 17 Jan 2024 09:02:10 +0100	[thread overview]
Message-ID: <20240117080414.316890-7-eric.auger@redhat.com> (raw)
In-Reply-To: <20240117080414.316890-1-eric.auger@redhat.com>

As we have just removed the only implementation of
iommu_set_iova_ranges IOMMU MR callback in the virtio-iommu,
let's remove the call to the memory wrapper. Usable IOVA ranges
are now conveyed through the PCIIOMMUOps in VFIO-PCI.
