On the other side, we have the zdev support, which both requires s390

Is there a reason why CONFIG_VFIO_PCI_ZDEV exists? Why not just always
return the s390 specific data in VFIO_DEVICE_GET_INFO if running on
s390?
It would be like returning data from ACPI on other platforms.
Agree.
all agree that I remove it ?
we already have a check in the code:
if (ret && ret != -ENODEV) {
pci_warn(vdev->vpdev.pdev, "Failed to
setup zPCI info capabilities\n");
return ret;
}
so in case its not zdev we should get -ENODEV and continue in the good flow.
It really seems like part of vfio-pci-core
