This patch permits adding any sysbus device (it still needs to be user_creatable) when using the -preconfig experimental option. Signed-off-by: Damien Hedde --- This commit is RFC. Depending on the condition to allow a device to be added, it may change. --- softmmu/qdev-monitor.c | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) diff --git a/softmmu/qdev-monitor.c b/softmmu/qdev-monitor.c index f1c9242855..73b991adda 100644 --- a/softmmu/qdev-monitor.c +++ b/softmmu/qdev-monitor.c @@ -269,8 +269,13 @@ static DeviceClass *qdev_get_device_class(const char *= *driver, Error **errp) return NULL; } =20 - if (object_class_dynamic_cast(oc, TYPE_SYS_BUS_DEVICE)) { - /* sysbus devices need to be allowed by the machine */ + if (object_class_dynamic_cast(oc, TYPE_SYS_BUS_DEVICE) && + phase_check(MACHINE_INIT_PHASE_READY)) { + /* + * Sysbus devices need to be allowed by the machine. + * We only check that after the machine is ready in order to let + * us add any user_creatable sysbus device during machine creation. + */ MachineClass *mc =3D MACHINE_CLASS(object_get_class(qdev_get_machi= ne())); if (!machine_class_is_dynamic_sysbus_dev_allowed(mc, *driver)) { error_setg(errp, "'%s' is not an allowed pluggable sysbus devi= ce " --=20 2.33.0
