Re: [libvirt] [PATCH v2 1/2] conf: new function virDomainPCIAddressSetAllMulti()

This utility function iterates through all devices looking for any with a PCI address that has function != 0 (which implies that multiple functions are in use on that slot), then uses an inner iterator to find the device that's on function 0 of that same slot and sets the "multi" in its virDomainDeviceInfo (as long as it hasn't already been set explicitly by someone who presumably has better information than we do).   It isn't yet called from anywhere, so will have no functional effect.

+static int +virDomainPCIAddressSetMultiIter(virDomainDefPtr def ATTRIBUTE_UNUSED, +                                virDomainDeviceDefPtr dev ATTRIBUTE_UNUSED, +                                virDomainDeviceInfoPtr info, +                                void *data)

+static int +virDomainPCIAddressSetAllMultiIter(virDomainDefPtr def, +                                   virDomainDeviceDefPtr dev ATTRIBUTE_UNUSED, +                                   virDomainDeviceInfoPtr info, +                                   void *data ATTRIBUTE_UNUSED) +{ +    virPCIDeviceAddressPtr testAddr; + +    if (!info || info->type != VIR_DOMAIN_DEVICE_ADDRESS_TYPE_PCI) +       return 0; + +    testAddr = &info->addr.pci;

+    if (testAddr->function != 0) { +        ignore_value(virDomainDeviceInfoIterate(def, +                                                virDomainPCIAddressSetMultiIter, +                                                testAddr)); +    } + +    return 0; +}
