John Keeping f2227f4697 drm/rockchip: don't wait for vblank if fb hasn't changed ... As commented in drm_atomic_helper_wait_for_vblanks(), userspace relies on cursor ioctls being unsynced. Converting the rockchip driver to atomic has significantly impacted cursor performance by making every cursor update wait for vblank. By skipping the vblank sync when the framebuffer has not changed (as is done in drm_atomic_helper_wait_for_vblanks()) we can avoid this for the common case of moving the cursor and only need to delay the cursor ioctl when the cursor icon changes. We cannot add the check on legacy_cursor_update since that results in the cursor bo being unreferenced while the hardware may still be reading it. Fully supporting unsynced cursor updates is left for the future when the atomic helper framework supports async updates.
