+The base structure for all KMS objects is :c:type:`struct drm_mode_object +<drm_mode_object>`. One of the base services it provides is tracking properties, +which are especially important for the atomic IOCTL (see `Atomic Mode +Setting`_). The somewhat surprising part here is that properties are not +directly instantiated on each object, but free-standing mode objects themselves, +represented by :c:type:`struct drm_property <drm_property>`, which only specify +the type and value range of a property. Any given property can be attached +multiple times to different objects using :c:func:`drm_object_attach_property() +<drm_object_attach_property>`.
