The KMS framework uses two slightly different definitions for the state concept. 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. Thus, drm_atomic_state isn't the entire device state, but only the full state of some objects in that device. This has been an endless source of confusion and thus bugs. We can rename the drm_atomic_state structure to drm_atomic_commit to make it less confusing. This patch was created using: rg -l drm_atomic_state | \ xargs sed -i 's/drm_atomic_state/drm_atomic_commit/g; s/drm_atomic_commit_helper/drm_atomic_state_helper/g' mv drivers/gpu/drm/tests/drm_atomic_state_test.c drivers/gpu/drm/tests/drm_atomic_commit_test.c Acked-by: Simona Vetter <[email protected]> Acked-by: Thomas Zimmermann <[email protected]> Acked-by: Jani Nikula <[email protected]> Reviewed-by: Luca Ceresoli <[email protected]> Tested-by: Luca Ceresoli <[email protected]> Signed-off-by: Maxime Ripard <[email protected]> Signed-off-by: Dave Airlie <[email protected]> Link: https://patch.msgid.link/[email protected]
