--- Comment #5 from Chris Wilson <chris at chris-wilson.co.uk> ---
The fencing in the kernel is enabled (not even opt out). X/Prime has been
assuming this works since its inception, but there may still be a bug or two in
delaying batches, a missing flush, when surfaces have been passed between
drivers. Both DRI2 and DRI3 with xrandr should just work. Outside of X, I'm not
sure what the current state is.
