On an older thread, @Jan_Bottorff, gave a nice synopsis of his use of full fledged ETW in a driver. Mr Bottoroff, are you able to log printf like messages (sort of like as in WPP) along with being able to log structured ETW-style events in your solution?
We’re currently using WPP but would also like to be able log structured events for xperf, etc.
Thanks,

Whether the trace data is structured or unstructured is an attribute of the stream. You can’t intermix the two in the same trace.
We’ve done both… but I can’t remember if we’ve ever done both structured tracing and WPP tracing in the same driver. I don’t see why it wouldn’t work (two different trace GUIDs)… but can’t say I know for sure.

Ok - I’ll look further into it. Thanks!
of course you can - you just make a structured event that is something like ‘%s’ and then dump the unstructured data into the structured log. Whether this is useful or a good idea is another question, but it is certainly possible.
