Detailed Description
struct drm_mode_object - base structure for modeset objects @id: userspace visible identifier @type: type of the object, one of DRM_MODE_OBJECT_* @properties: properties attached to this object, including values @refcount: reference count for objects with dynamic lifetime @free_cb: free function callback, only set for objects with dynamic lifetime
Base structure for modeset objects visible to userspace. Objects can be looked up using drm_mode_object_find(). Besides basic uapi interface properties like @id and @type it provides two services:
- It tracks attached properties and their values. This is used by &drm_crtc, &drm_plane and &drm_connector. Properties are attached by calling drm_object_attach_property() before the object is visible to userspace.
- For objects with dynamic lifetimes (as indicated by a non-NULL @free_cb) it provides reference counting through drm_mode_object_get() and drm_mode_object_put(). This is used by &drm_framebuffer, &drm_connector and &drm_property_blob. These objects provide specialized reference counting wrappers.
