No. VFIO-PLATFORM-DRIVER is _always_ explicit_bind_only and thus will be statically set in the driver. See Kim's patch. > - Then for the devices user want, set device->explicit_bind_only. > - unbind DEVICE from DRIVER1 > - bind DEVICE with VFIO-PLATFORM-DRIVER.

Otherwise, it looks correct to me. Stuart
