Add trace events to track the progress of a GPU submission msm_gpu_submit occurs at the beginning of the submissions, msm_gpu_submit_flush happens when the submission is put on the ringbuffer and msm_submit_flush_retired is sent when the operation is retired. To make it easier to track the operations a unique sequence number is assigned to each submission and displayed in each event output so a human or a script can easily associate the events related to a specific submission.
