From 33bf7481971a622a2b8c8aaa0e5e61a6eaeecd71 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Fri, 25 Jul 2014 16:56:15 +0200 Subject: [PATCH] perf record: Always force PERF_RECORD_FINISHED_ROUND event The PERF_RECORD_FINISHED_ROUND synthetic record governs queue flushing in reporting, so it needs to be stored for any kind of event. The lack of such periodic flushing made the tools use more memory than needed, as the reordering was being done only after processing all events. This was the case when no tracepoints were in the mix. Forcing the PERF_RECORD_FINISHED_ROUND event to be stored for all event types.
