Include a bool to show whether the request is complete in every
tracepoint. This especially helps when tracing the flow of requests
through the HW.

Wouldn't i915_request_hw class be more interesting for things like the
preemption bug?
And you mentioned you would like to see priority in there as well?
I am just thinking is completed status to all is not an overkill. Well,
only from the angle of manually looking at the traces it may be too
noisy. Not sure yet.
