[Intel-gfx] [PATCH v3 09/11] drm/i915: Update atomic modeset state synchronously, v2.

Maarten Lankhorst maarten.lankhorst at linux.intel.com
Tue Nov 8 12:55:40 UTC 2016


All of this state should be updated as soon as possible. It shouldn't be
done later because then future updates may not depend on it.

Changes since v1:
- Move the modeset update to before drm_atomic_state_get. (Ville)
