[Qemu-devel] [PATCH RFC v5 1/5] hw/vfio/common: Do not print error when viommu translates into an mmio region
Posted by Bharat Bhushan 6 years, 11 months ago
From: Eric Auger <eric.auger@redhat.com>

On ARM, the MSI doorbell is translated by the virtual IOMMU.
As such address_space_translate() returns the MSI controller
MMIO region and we get an "iommu map to non memory area"
message. Let's remove this latter.
