I.e.: $ cat ~/share/perf-core/strace/groups/file access chmod creat execve faccessat getcwd lstat mkdir open openat quotactl readlink rename rmdir stat statfs symlink unlink $ Then, on a quiet desktop, try running this and then moving your mouse to see the deluge of mouse related activity: # perf probe 'vfs_getname=getname_flags:72 pathname=filename:string' Added new event: probe:vfs_getname (on getname_flags:72 with pathname=filename:string) You can now use it in all perf tools, such as: perf record -e probe:vfs_getname -aR sleep 1 # # trace --ev probe:vfs_getname --filter-pids 2232 -e file 0.042 (0.042 ms): mousetweaks/2235 open(filename: 0x14e3910, mode: 438 ) ... 0.042 ( ): probe:vfs_getname:(ffffffff812230bc) pathname="/home/acme/.icons/Adwaita/cursors/xterm") 0.100 (0.100 ms): mousetweaks/2235 ...

Now, if you're bored, please write some more syscall groups, like the ones in 'strace' and send it our way :-) Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Borislav Petkov <bp@suse.de> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Milian Wolff <mail@milianw.de> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-a42xklu59lcbxp7bbnic74a8@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
