SYNOPSIS

void drm_atomic_helper_commit_modeset_enables(struct drm_device * dev, struct drm_atomic_state * old_state);

ARGUMENTS

dev

DRM device

old_state

atomic state object with old state structures

DESCRIPTION

This function enables all the outputs with the new configuration which had to be turned off for the update.

For compatibility 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.
