[PATCH 01/11] drm/vmwgfx: Add universal plane support
Sinclair Yeh
syeh at vmware.com
Mon Mar 27 22:00:54 UTC 2017
Universal support is prerequisite for atomic mode set.
Explicitly create planes for the cursor and the primary FB. With
a functional cursor plane, the DRM will no longer use the legacy
cursor_set2 and cursor_move entry points.
