drm_atomic_helper_commit_modeset_enables — modeset commit to enable outputs
void drm_atomic_helper_commit_modeset_enables ( | struct drm_device * dev, |
struct drm_atomic_state * old_state); |
This function enables all the outputs with the new configuration which had to be turned off for the update.
For compatability with legacy crtc helpers this should be called after
drm_atomic_helper_commit_planes, which is what the default commit function
does. But drivers with different needs can group the modeset commits together
and do the plane commits at the end. This is useful for drivers doing runtime
PM since planes updates then only happen when the CRTC is actually enabled.
