[PATCH v2 06/13] hw/pci-host/q35: Initialize "bypass-iommu" property from board code |
Date: |
Sat, 4 Mar 2023 16:26:41 +0100 |
The Q35 PCI host already has a "bypass-iommu" property. However, the
host initializes this property itself by accessing global machine state,
thereby assuming it to be a PC machine. Avoid this by having board code
set this property.
