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/atmel-hlcdc/atmel_hlcdc_plane.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_plane.c') diff --git a/drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_plane.c b/drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_plane.c index a32d45bcc386..cff52098e087 100644 --- a/drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_plane.c +++ b/drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_plane.c @@ -733,12 +733,13 @@ static void atmel_hlcdc_plane_atomic_disable(struct drm_plane *p, static void atmel_hlcdc_plane_atomic_update(struct drm_plane *p, struct drm_plane_state *old_s) { + struct drm_plane_state *new_s = p->state; struct atmel_hlcdc_plane *plane = drm_plane_to_atmel_hlcdc_plane(p); struct atmel_hlcdc_plane_state *hstate = - drm_plane_state_to_atmel_hlcdc_plane_state(p->state); + drm_plane_state_to_atmel_hlcdc_plane_state(new_s); u32 sr; - if (!p->state->crtc || !p->state->fb) + if (!new_s->crtc || !new_s->fb) return; if (!hstate->base.visible) { -- cgit v1.2.3
