[PATCH v3 05/17] hw/pci-host/q35: Initialize PCI_HOST_BYPASS_IOMMU property from board code |
Date: |
Fri, 30 Jun 2023 09:37:08 +0200 |
The Q35 PCI host already has a PCI_HOST_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.
