From c3492a3a4e58117f18d96125e67b0bed7c4231e1 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Tue, 12 Jul 2016 19:04:54 +0900 Subject: perf probe: Make --list show only available cached events Make "perf probe --cache --list" show only available cached events by checking build-id validity. E.g. without this patch: ---- $ ./perf probe --cache --add oldevent=cmd_probe $ make #(to update ./perf) $ ./perf probe --cache --add newevent=cmd_probe $ ./perf probe --cache --list /home/mhiramat/ksrc/linux/tools/perf/perf (061e90539bac69 probe_perf:newevent=cmd_probe /home/mhiramat/ksrc/linux/tools/perf/perf (c2e44d614e33e1 probe_perf:oldevent=cmd_probe ---- It shows both of old and new events but user can not use old one. With this; ---- $ ./perf probe --cache -l /home/mhiramat/ksrc/linux/tools/perf/perf (061e90539bac69 probe_perf:newevent=cmd_probe ---- This shows only new events which are on the existing binary.
