When the device offers the probe feature, send a probe request for each device managed by the IOMMU. Extract RESV_MEM information. When we encounter a MSI doorbell region, set it up as a IOMMU_RESV_MSI region. This will tell other subsystems that there is no need to map the MSI doorbell in the virtio-iommu, because MSIs bypass it. Signed-off-by: Jean-Philippe Brucker <jean-philippe.brucker at
