Adding --ldlat option to specify desired latency for loads event. Specify 50 as loads event latency: $ perf mem record -e ldlat-loads -v --ldlat 50 true calling: record -W -d -e cpu/mem-loads,ldlat=50/P true Signed-off-by: Jiri Olsa <jolsa@kernel.org> Cc: David Ahern <dsahern@gmail.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1465928361-2442-2-git-send-email-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
