    drm: Use a nondestructive mode for output detect when polling · 7b334fcb
    Chris Wilson authored Sep 09, 2010
    Destructive load-detection is very expensive and due to failings
    elsewhere can trigger system wide stalls of up to 600ms. A simple
    first step to correcting this is not to invoke such an expensive
    and destructive load-detection operation automatically.
