[PATCH 08/20] drm/i915: Don't use encoder->new_crtc in intel_modeset_pipe_config()

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

 



Move towards atomic by using the legacy modeset's drm_atomic_state
instead.

v2: Move call to drm_atomic_add_affected_connectors() to
    intel_modeset_compute_config(). (Daniel)
