From 62605dc50c27bf0e4ff69b7b3166f226586aff02 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 11 Nov 2013 09:44:09 -0300 Subject: perf record: Synthesize non-exec MMAP records when --data used When perf_event_attr.mmap_data is set the kernel will generate PERF_RECORD_MMAP events when non-exec (data, SysV mem) mmaps are created, so we need to synthesize from /proc/pid/maps for existing threads, as we do for exec mmaps. Right now just 'perf record' does it, but any other tool that uses perf_event__synthesize_thread(s|map) can request it.
