[PATCH 1/2] drm: Move plane->{fb, old_fb, crtc} to legacy sub-structure

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

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Hide the plane->fb/etc. footguns better by stashing them inside
a "legacy" sub struct.

Eventually maybe we could turn 'legacy' into a pointer
that only exists on legacy drivers to completely prevent
any abuse by atomic drivers...

Side note: _dpu_plane_set_danger_state() looks completely
broken.
