From f1c37e1adc6eca1fb492c74d466141d9b01e0428 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Tue, 25 Nov 2014 12:09:44 +0100 Subject: drm/plane: Pass old state to ->atomic_update() In most situations it will be useful to have the old state passed to the ->atomic_update() callback. For example if a plane is being disabled the new state's .crtc field will be NULL, but some drivers may rely on this field to program the CRTCs registers. v2: rename variable to old_plane_state and remove redundant comment as suggested by Daniel Vetter, remove an Exynos hunk that doesn't apply to drm-next and add a hunk for pending MSM mdp5 changes Reviewed-by: Daniel Vetter Signed-off-by: Thierry Reding Signed-off-by: Daniel Vetter --- include/drm/drm_plane_helper.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'include/drm') diff --git a/include/drm/drm_plane_helper.h b/include/drm/drm_plane_helper.h index c48f14d88690..fcfa969523fb 100644 --- a/include/drm/drm_plane_helper.h +++ b/include/drm/drm_plane_helper.h @@ -60,7 +60,8 @@ struct drm_plane_helper_funcs { int (*atomic_check)(struct drm_plane *plane, struct drm_plane_state *state); - void (*atomic_update)(struct drm_plane *plane); + void (*atomic_update)(struct drm_plane *plane, + struct drm_plane_state *old_state); }; static inline void drm_plane_helper_add(struct drm_plane *plane, -- cgit v1.2.3
