Starting qemu with
qemu-system-x86_64 -S -M isapc -device {amd|intel}-iommu
leads to a segfault. The code assume PCI bus is present and
tries to access the bus structure without checking.
The patch series moves the error checks from vtd_realize()
and amdvi_realize() to the generic x86_iommu_realize() and
adds a check for PCI bus presence.
Mohammed Gamal (2):
x86_iommu: Move machine check to x86_iommu_realize()
x86_iommu: check if machine has PCI bus
