From e05162c017e2e14b94dfd4e55d2f006a9a642c6d Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 19 Feb 2021 13:00:27 +0100 Subject: drm: Store new plane state in a variable for atomic_update and disable In order to store the new plane state in a subsequent helper, let's move the plane->state dereferences into a variable. This was done using the following coccinelle script, plus some hand changes for vmwgfx: @ plane_atomic_func @ identifier helpers; identifier func; @@ ( static const struct drm_plane_helper_funcs helpers = { ..., .atomic_disable = func, ..., }; | static const struct drm_plane_helper_funcs helpers = { ..., .atomic_update = func, ..., }; ) @ has_new_state_old_state @ identifier plane_atomic_func.func; identifier plane; identifier new_state; symbol old_state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_state) { ... struct drm_plane_state *new_state = plane->state; ... } @ depends on !has_new_state_old_state @ identifier plane_atomic_func.func; identifier plane; symbol old_state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_state) { + struct drm_plane_state *new_state = plane->state; <+... - plane->state + new_state ...+> } @ has_new_state_state @ identifier plane_atomic_func.func; identifier plane; identifier new_state; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *state) { ... struct drm_plane_state *new_state = plane->state; ... } @ depends on !has_new_state_state @ identifier plane_atomic_func.func; identifier plane; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *state) { + struct drm_plane_state *new_plane_state = plane->state; <+... - plane->state + new_plane_state ...+> } @ has_new_state_old_s @ identifier plane_atomic_func.func; identifier plane; identifier new_state; symbol old_s; @@ func(struct drm_plane *plane, struct drm_plane_state *old_s) { ... struct drm_plane_state *new_state = plane->state; ... } @ depends on !has_new_state_old_s @ identifier plane_atomic_func.func; identifier plane; symbol old_s; @@ func(struct drm_plane *plane, struct drm_plane_state *old_s) { + struct drm_plane_state *new_s = plane->state; <+... - plane->state + new_s ...+> } Reviewed-by: Laurent Pinchart Signed-off-by: Maxime Ripard Acked-by: Thomas Zimmermann Link: https://lore.kernel.org/r/20210219120032.260676-1-maxime@cerno.tech --- drivers/gpu/drm/xlnx/zynqmp_disp.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'drivers/gpu/drm/xlnx') diff --git a/drivers/gpu/drm/xlnx/zynqmp_disp.c b/drivers/gpu/drm/xlnx/zynqmp_disp.c index 27c0b849598b..8b87a17e9d56 100644 --- a/drivers/gpu/drm/xlnx/zynqmp_disp.c +++ b/drivers/gpu/drm/xlnx/zynqmp_disp.c @@ -1179,11 +1179,12 @@ static void zynqmp_disp_plane_atomic_update(struct drm_plane *plane, struct drm_plane_state *old_state) { + struct drm_plane_state *new_state = plane->state; struct zynqmp_disp_layer *layer = plane_to_layer(plane); bool format_changed = false; if (!old_state->fb || - old_state->fb->format->format != plane->state->fb->format->format) + old_state->fb->format->format != new_state->fb->format->format) format_changed = true; /* @@ -1195,10 +1196,10 @@ zynqmp_disp_plane_atomic_update(struct drm_plane *plane, if (old_state->fb) zynqmp_disp_layer_disable(layer); - zynqmp_disp_layer_set_format(layer, plane->state); + zynqmp_disp_layer_set_format(layer, new_state); } - zynqmp_disp_layer_update(layer, plane->state); + zynqmp_disp_layer_update(layer, new_state); /* Enable or re-enable the plane is the format has changed. */ if (format_changed) -- cgit v1.2.3-59-g8ed1b
