[PATCH 02/15] drm/i915: Use drm_mode_get_hv_timing() to populate plane clip rectangle

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Use drm_mode_get_hv_timing() to fill out the plane clip rectangle.
No functional changes since pipe_src_w/h are already filled via
drm_mode_get_hv_timing().

Once everyone agrees on this we can move the clip handling into
drm_atomic_helper_check_plane_state().
