The error detection event is a good indicator of when things * began to go badly. The value supplied with the event is a 1 upon error * detection, and a 0 upon reset completion, signifying no more error * exists. NOTE: Disabling hangcheck or reset via module parameter will * cause the related events to not be seen. * * I915_RESET_UEVENT - Event is generated just before an attempt to reset the * the GPU.
