Suppress unsupported event warnings in quipper |
|||||||
Issue description
From tipp:
We've started getting this warning. It's harmless, but log spew is annoying. I'd like to see the type supported, or just suppress the warning.
[perf_reader.cc:1890] Event type 82 is not yet supported!
Look like this is:
PERF_RECORD_HEADER_PMU_MAPPINGS = 82,

By fixed, I mean the error message is suppressed, not that it's handled.

You had fixed it in perf_serializer.cc. I'm fixing it in perf_reader.cc.

Right, I noticed the difference when you sent the CL for review :)
