There's an event mechanism still to come - mostly for communicating fences and shader interrupts back to userspace, but also used for "device change" notifications, so no polling of sysfs. That could would be interesting. On i915 my plan is to internally use the recently added struct fence from Maarten. For the external interface for userspace that wants explicit control over fences I'm leaning towards polishing the android syncpt stuff (currently in staging). But in any case I _really_ want to avoid that we end up with multiple different and incompatible explicit fencing interfaces on linux.
