[Qemu-devel] [PATCH 0/4] Remove some qdev_get_machine() calls from CONFIG_USER_ONLY

[Eduardo Habkost]

This series moves some qdev code outside qdev.o, so it can be
compiled only in CONFIG_SOFTMMU.

The code being moved includes two qdev_get_machine() calls, so
this will make it easier to move qdev_get_machine() to
CONFIG_SOFTMMU later.

After this series, there's one remaining qdev_get_machine() call
that seems more difficult to remove:

    static void device_set_realized(Object *obj, bool value, Error **errp)
    {
        /* [...] */
        if (!obj->parent) {
            gchar *name = g_strdup_printf("device[%d]", unattached_count++);

            object_property_add_child(container_get(qdev_get_machine(),
                                                    "/unattached"),
                                      name, obj, &error_abort);
            unattached_parent = true;
            g_free(name);
        }
        /* [...] */
    }

This one is tricky because on system emulation mode it needs
"/machine" to already exist, but in user-only mode it needs to
implicitly create a "/machine" container.

Eduardo Habkost (4):
  machine: Move gpio code to hw/core/gpio.c
  move qdev hotplug code to qdev-hotplug.c
  qdev: Don't compile hotplug code in user-mode emulation
  qdev-hotplug: Don't check type of qdev_get_machine()
