From ba5c1649465d40a0557e67bc9819ef687a7d99f4 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 19 Feb 2021 13:00:22 +0100 Subject: drm: Rename plane atomic_check state names Most drivers call the argument to the plane atomic_check hook simply state, which is going to conflict with the global atomic state in a later rework. Let's rename it to new_plane_state (or new_state depending on the convention used in the driver). This was done using the coccinelle script below, and built tested: @ plane_atomic_func @ identifier helpers; identifier func; @@ static const struct drm_plane_helper_funcs helpers = { .atomic_check = func, }; @ has_old_state @ identifier plane_atomic_func.func; identifier plane; expression e; symbol old_state; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *state) { ... struct drm_plane_state *old_state = e; ... } @ depends on has_old_state @ identifier plane_atomic_func.func; identifier plane; symbol old_state; @@ func(struct drm_plane *plane, - struct drm_plane_state *state + struct drm_plane_state *new_state ) { <+... - state + new_state ...+> } @ has_state @ identifier plane_atomic_func.func; identifier plane; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *state) { ... } @ depends on has_state @ identifier plane_atomic_func.func; identifier plane; symbol old_state; @@ func(struct drm_plane *plane, - struct drm_plane_state *state + struct drm_plane_state *new_plane_state ) { <+... - state + new_plane_state ...+> } Reviewed-by: Laurent Pinchart Signed-off-by: Maxime Ripard Acked-by: Thomas Zimmermann Link: https://patchwork.freedesktop.org/patch/msgid/20210219120032.260676-2-maxime@cerno.tech --- drivers/gpu/drm/tidss/tidss_plane.c | 34 +++++++++++++++++++--------------- 1 file changed, 19 insertions(+), 15 deletions(-) (limited to 'drivers/gpu/drm/tidss/tidss_plane.c') diff --git a/drivers/gpu/drm/tidss/tidss_plane.c b/drivers/gpu/drm/tidss/tidss_plane.c index 795d24b44091..2674fffa67e2 100644 --- a/drivers/gpu/drm/tidss/tidss_plane.c +++ b/drivers/gpu/drm/tidss/tidss_plane.c @@ -20,7 +20,7 @@ /* drm_plane_helper_funcs */ static int tidss_plane_atomic_check(struct drm_plane *plane, - struct drm_plane_state *state) + struct drm_plane_state *new_plane_state) { struct drm_device *ddev = plane->dev; struct tidss_device *tidss = to_tidss(ddev); @@ -33,20 +33,22 @@ static int tidss_plane_atomic_check(struct drm_plane *plane, dev_dbg(ddev->dev, "%s\n", __func__); - if (!state->crtc) { + if (!new_plane_state->crtc) { /* * The visible field is not reset by the DRM core but only * updated by drm_plane_helper_check_state(), set it manually. */ - state->visible = false; + new_plane_state->visible = false; return 0; } - crtc_state = drm_atomic_get_crtc_state(state->state, state->crtc); + crtc_state = drm_atomic_get_crtc_state(new_plane_state->state, + new_plane_state->crtc); if (IS_ERR(crtc_state)) return PTR_ERR(crtc_state); - ret = drm_atomic_helper_check_plane_state(state, crtc_state, 0, + ret = drm_atomic_helper_check_plane_state(new_plane_state, crtc_state, + 0, INT_MAX, true, true); if (ret < 0) return ret; @@ -63,35 +65,37 @@ static int tidss_plane_atomic_check(struct drm_plane *plane, * check for odd height). */ - finfo = drm_format_info(state->fb->format->format); + finfo = drm_format_info(new_plane_state->fb->format->format); - if ((state->src_x >> 16) % finfo->hsub != 0) { + if ((new_plane_state->src_x >> 16) % finfo->hsub != 0) { dev_dbg(ddev->dev, "%s: x-position %u not divisible subpixel size %u\n", - __func__, (state->src_x >> 16), finfo->hsub); + __func__, (new_plane_state->src_x >> 16), finfo->hsub); return -EINVAL; } - if ((state->src_y >> 16) % finfo->vsub != 0) { + if ((new_plane_state->src_y >> 16) % finfo->vsub != 0) { dev_dbg(ddev->dev, "%s: y-position %u not divisible subpixel size %u\n", - __func__, (state->src_y >> 16), finfo->vsub); + __func__, (new_plane_state->src_y >> 16), finfo->vsub); return -EINVAL; } - if ((state->src_w >> 16) % finfo->hsub != 0) { + if ((new_plane_state->src_w >> 16) % finfo->hsub != 0) { dev_dbg(ddev->dev, "%s: src width %u not divisible by subpixel size %u\n", - __func__, (state->src_w >> 16), finfo->hsub); + __func__, (new_plane_state->src_w >> 16), + finfo->hsub); return -EINVAL; } - if (!state->visible) + if (!new_plane_state->visible) return 0; - hw_videoport = to_tidss_crtc(state->crtc)->hw_videoport; + hw_videoport = to_tidss_crtc(new_plane_state->crtc)->hw_videoport; - ret = dispc_plane_check(tidss->dispc, hw_plane, state, hw_videoport); + ret = dispc_plane_check(tidss->dispc, hw_plane, new_plane_state, + hw_videoport); if (ret) return ret; -- cgit v1.2.3
