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/arc/arcpgu_crtc.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'drivers/gpu/drm/arc') diff --git a/drivers/gpu/drm/arc/arcpgu_crtc.c b/drivers/gpu/drm/arc/arcpgu_crtc.c index 895cdd991af6..2cea17a96d5c 100644 --- a/drivers/gpu/drm/arc/arcpgu_crtc.c +++ b/drivers/gpu/drm/arc/arcpgu_crtc.c @@ -147,14 +147,15 @@ static const struct drm_crtc_helper_funcs arc_pgu_crtc_helper_funcs = { static void arc_pgu_plane_atomic_update(struct drm_plane *plane, struct drm_plane_state *state) { + struct drm_plane_state *new_plane_state = plane->state; struct arcpgu_drm_private *arcpgu; struct drm_gem_cma_object *gem; - if (!plane->state->crtc || !plane->state->fb) + if (!new_plane_state->crtc || !new_plane_state->fb) return; - arcpgu = crtc_to_arcpgu_priv(plane->state->crtc); - gem = drm_fb_cma_get_gem_obj(plane->state->fb, 0); + arcpgu = crtc_to_arcpgu_priv(new_plane_state->crtc); + gem = drm_fb_cma_get_gem_obj(new_plane_state->fb, 0); arc_pgu_write(arcpgu, ARCPGU_REG_BUF0_ADDR, gem->paddr); } -- cgit v1.2.3
