drm/atomic: Pass the full state to planes atomic_check
The current atomic helpers have either their object state being passed as an argument or the full atomic state. The former is the pattern that was done at first, before switching to the latter for new hooks or when it was needed. Let's convert all the remaining helpers to provide a consistent interface, starting with the planes atomic_check. The conversion was done using the coccinelle script below plus some manual changes for vmwgfx, built tested on all the drivers. @@ identifier plane, plane_state; symbol state; @@ struct drm_plane_helper_funcs { ... int (*atomic_check)(struct drm_plane *plane, - struct drm_plane_state *plane_state); + struct drm_atomic_state *state); ... } @ plane_atomic_func @ identifier helpers; identifier func; @@ static const struct drm_plane_helper_funcs helpers = { ..., .atomic_check = func, ..., }; @@ struct drm_plane_helper_funcs *FUNCS; identifier f; identifier dev; identifier plane, plane_state, state; @@ f(struct drm_device *dev, struct drm_atomic_state *state) { <+... - FUNCS->atomic_check(plane, plane_state) + FUNCS->atomic_check(plane, state) ...+> } @ ignores_new_state @ identifier plane_atomic_func.func; identifier plane, new_plane_state; @@ func(struct drm_plane *plane, struct drm_plane_state *new_plane_state) { ... when != new_plane_state } @ adds_new_state depends on plane_atomic_func && !ignores_new_state @ identifier plane_atomic_func.func; identifier plane, new_plane_state; @@ func(struct drm_plane *plane, struct drm_plane_state *new_plane_state) { + struct drm_plane_state *new_plane_state = drm_atomic_get_new_plane_state(state, plane); ... } @ depends on plane_atomic_func @ identifier plane_atomic_func.func; identifier plane, new_plane_state; @@ func(struct drm_plane *plane, - struct drm_plane_state *new_plane_state + struct drm_atomic_state *state ) { ... } @ include depends on adds_new_state @ @@ #include <drm/drm_atomic.h> @ no_include depends on !include && adds_new_state @ @@ + #include <drm/drm_atomic.h> #include <drm/...> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Maxime Ripard <maxime@cerno.tech> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20210219120032.260676-4-maxime@cerno.tech
