I think you actually moved the min/max_vbl asignment to happen after this tracepoint is called. So this is busted.

Same could be done for the i915_pipe_update_end tracepoint, but there we'd have to pass it in obviously since we don't keep the end values in the struct. But these two are purely optional ideas.
