Using QLitObject lets us get rid of most of the .set_default_value functions, and just use object_property_set_default() directly.
Signed-off-by: Eduardo Habkost <ehabk...@redhat.com> --- Changes v1 -> v2: * Instead of initializing defval to QLIT_QNULL by default, just check for QTYPE_NONE, to find out if .defval was explicitly set. This avoids extra complexity at set_prop_arraylen(). --- include/hw/qdev-properties-system.h | 2 +- include/qom/field-property-internal.h | 4 --- include/qom/field-property.h | 26 ++++++++----------- include/qom/property-types.h | 19 ++++++-------- hw/core/qdev-properties-system.c | 8 ------ qom/field-property.c | 27 ++++++++++++++------ qom/property-types.c | 36 ++++----------------------- 7 files changed, 42 insertions(+), 80 deletions(-) diff --git a/include/hw/qdev-properties-system.h b/include/hw/qdev-properties-system.h index 0ac327ae60..a586424a33 100644 --- a/include/hw/qdev-properties-system.h +++ b/include/hw/qdev-properties-system.h @@ -65,7 +65,7 @@ extern const PropertyInfo qdev_prop_pcie_link_width; #define DEFINE_PROP_UUID(_name, _state, _field) \ DEFINE_PROP(_name, _state, _field, qdev_prop_uuid, QemuUUID, \ - .set_default = true) + .defval = QLIT_QSTR("auto")) #define DEFINE_PROP_AUDIODEV(_n, _s, _f) \ DEFINE_PROP(_n, _s, _f, qdev_prop_audiodev, QEMUSoundCard) diff --git a/include/qom/field-property-internal.h b/include/qom/field-property-internal.h index a7b7e2b69d..9bc29e9b67 100644 --- a/include/qom/field-property-internal.h +++ b/include/qom/field-property-internal.h @@ -15,10 +15,6 @@ void field_prop_set_enum(Object *obj, Visitor *v, const char *name, void field_prop_set_default_value_enum(ObjectProperty *op, const Property *prop); -void field_prop_set_default_value_int(ObjectProperty *op, - const Property *prop); -void field_prop_set_default_value_uint(ObjectProperty *op, - const Property *prop); void field_prop_get_int32(Object *obj, Visitor *v, const char *name, void *opaque, Error **errp); diff --git a/include/qom/field-property.h b/include/qom/field-property.h index 0cb1fe2217..3cfd19cc14 100644 --- a/include/qom/field-property.h +++ b/include/qom/field-property.h @@ -6,6 +6,7 @@ #include "qom/object.h" #include "qapi/util.h" +#include "qapi/qmp/qlit.h" /** * struct Property: definition of a field property @@ -27,21 +28,8 @@ struct Property { const PropertyInfo *info; ptrdiff_t offset; uint8_t bitnr; - /** - * @set_default: true if the default value should be set from @defval, - * in which case @info->set_default_value must not be NULL - * (if false then no default value is set by the property system - * and the field retains whatever value it was given by instance_init). - */ - bool set_default; - /** - * @defval: default value for the property.
