drm_atomic_helper_wait_for_vblanks — wait for vblank on crtcs
void drm_atomic_helper_wait_for_vblanks ( | struct drm_device * dev, |
struct drm_atomic_state * old_state); |
Helper to, after atomic commit, wait for vblanks on all effected
crtcs (ie. before cleaning up old framebuffers using
drm_atomic_helper_cleanup_planes). It will only wait on crtcs where the
framebuffers have actually changed to optimize for the legacy cursor and
plane update use-case.
