Messages in this thread Patch in this message | | | Subject | [PATCH -tip v2 3/8] perf-probe: Show in what binaries/modules probes are set | From | Masami Hiramatsu <> | Date | Wed, 29 Jan 2014 09:14:57 +0000 |
| |
Show the name of binary file or modules in which the probes are set with --list option.
Without this change;
# ./perf probe -m drm drm_av_sync_delay # ./perf probe -x perf dso__load_vmlinux
# ./perf probe -l probe:drm_av_sync_delay (on drm_av_sync_delay) probe_perf:dso__load_vmlinux (on 0x000000000006d110)
With this change;
# ./perf probe -l probe:drm_av_sync_delay (on drm_av_sync_delay in drm) probe_perf:dso__load_vmlinux (on 0x000000000006d110 in /kbuild/ksrc/linux-3/tools/perf/perf)
