For a given object (plane, CRTC, encoder, etc., so +``drm_$OBJECT_state``), the state is the entire state of that object. However, +at the device level, ``drm_atomic_state`` refers to a state update for a +limited number of objects. + +The state isn't the entire device state, but only the full state of some +objects in that device. This is confusing to newcomers, and +``drm_atomic_state`` should be renamed to something clearer like +``drm_atomic_commit``. + +In addition to renaming the structure itself, it would also imply renaming some +related functions (``drm_atomic_state_alloc``, ``drm_atomic_state_get``, +``drm_atomic_state_put``, ``drm_atomic_state_init``, +``__drm_atomic_state_free``, etc.). + +Contact: Maxime Ripard <mripard@kernel.org> + +Level: Advanced + Fallout from atomic KMS ----------------------- |
