Tsirkin" Errors-To: qemu-devel-bounces+qemu-devel=archiver.kernel.org@nongnu.org Sender: "Qemu-devel" isa_superio_realize() attempts to make isa-parallel and isa-serial QOM children, but this does not work, because it calls object_property_add_child() after realizing with qdev_init_nofail(). Realizing a device without a parent gives it one: it gets put into the "/machine/unattached/" orphanage. The extra object_property_add_child() fails, and isa_superio_realize() ignores the error. Move the object_property_add_child() before qdev_init_nofail(), and pass &error_abort. For the other components, isa_superio_realize() doesn't even try. Add object_property_add_child() there. This affects machines 40p, clipper and fulong2e. For instance, fulong2e has its vt82c686b-superio (which is an isa-superio) at /machine/unattached/device[9]. Before the patch, its components are at /machine/unattached/device[10] .. [14]. Afterwards, they are at /machine/unattached/device[9]/{parallel0,serial0,serial1,isa-fdc,i8042}. Cc: Michael S.
