No functional changes as the code already uses crtc_state->mode to populate the clip, which is also what drm_mode_get_hv_timing() uses. Once everyone agrees on this we can move the clip handling into drm_atomic_helper_check_plane_state(). v2: Rebase due to tegra_plane_state_add() relocating to plane.c Cc: Laurent Pinchart Cc: Thierry Reding Cc: linux-tegra@vger.kernel.org Signed-off-by: Ville Syrjälä Acked-by: Thierry Reding Reviewed-by: Thierry Reding Link: https://patchwork.freedesktop.org/patch/msgid/20171123190502.28449-13-ville.syrjala@linux.intel.com --- diff --git a/drivers/gpu/drm/tegra/plane.c b/drivers/gpu/drm/tegra/plane.c index 36a06a9..7267a01 100644 --- a/drivers/gpu/drm/tegra/plane.c +++ b/drivers/gpu/drm/tegra/plane.c @@ -82,7 +82,7 @@ int tegra_plane_state_add(struct tegra_plane *plane, { struct drm_crtc_state *crtc_state; struct tegra_dc_state *tegra; - struct drm_rect clip; + struct drm_rect clip = {}; int err; /* Propagate errors from allocation or locking failures. */ @@ -90,10 +90,9 @@ int tegra_plane_state_add(struct tegra_plane *plane, if (IS_ERR(crtc_state)) return PTR_ERR(crtc_state); - clip.x1 = 0; - clip.y1 = 0; - clip.x2 = crtc_state->mode.hdisplay; - clip.y2 = crtc_state->mode.vdisplay; + if (crtc_state->enable) + drm_mode_get_hv_timing(&crtc_state->mode, + &clip.x2, &clip.y2); /* Check plane state for visibility and calculate clipping bounds */ err = drm_atomic_helper_check_plane_state(state, crtc_state, &clip,
