I thought the debuginfod was for perf report, not record. Maybe I'm missing something but how about moving it to report? We can talk to debuginfod after checking the local build-id cache and binary on the system.
Still, we can have perf buildid-cache to move it from the debuginfod to local cache.
Thanks, Namhyung
