Set the pci flags in xen_arch_domainconfig to enable vPCI for dom0. Signed-off-by: Stewart Hildebrand <stewart.hildebr...@amd.com> --- Julien had a suggestion to make this conditional on pci_passthrough_enabled [1]. However, in v5 of the PCI ARM SMMU series [2], we propose removing the pci_passthrough_enabled flag. If pci_passthrough_enabled is gone, the conditions under which vPCI should be enabled for dom0 aren't entirely clear to me (other than CONFIG_HAS_VPCI=y).
