Other perf tool builtins already supported a DSO filter. For example: $ perf report --dsos a,b,c which only considers symbols in these dsos. Now the DSO filter is supported in 'perf script': root@kbl-ppc:~# ./perf script --dsos "[kernel.kallsyms]" perf 18123 [000] 6142863.075104: 1 cycles: ffffffff9ca77308 native_write_msr+0x8 ([kernel.kallsyms]) perf 18123 [000] 6142863.075107: 1 cycles: ffffffff9ca77308 native_write_msr+0x8 ([kernel.kallsyms]) perf 18123 [000] 6142863.075108: 10 cycles: ffffffff9ca77308 native_write_msr+0x8 ([kernel.kallsyms]) perf 18123 [000] 6142863.075109: 273 cycles: ffffffff9ca7730a native_write_msr+0xa ([kernel.kallsyms]) perf 18123 [000] 6142863.075110: 7684 cycles: ffffffff9ca3c9c0 native_sched_clock+0x50 ([kernel.kallsyms]) perf 18123 [000] 6142863.075112: 213017 cycles: ffffffff9d765a92 syscall_exit_to_user_mode+0x32 ([kernel.kallsyms]) perf 18123 [001] 6142863.075156: 1 cycles: ffffffff9ca77308 native_write_msr+0x8 ([kernel.kallsyms]) perf 18123 [001] 6142863.075158: 1 cycles: ffffffff9ca77308 native_write_msr+0x8 ([kernel.kallsyms]) perf 18123 [001] 6142863.075159: 17 cycles: ffffffff9ca77308 native_write_msr+0x8 ([kernel.kallsyms]) Committer testing: $ perf script ls 2364888 29303.010949: 1 cycles:u: ffffffffa4bbc6a9 [unknown] ([unknown]) ls 2364888 29303.010957: 1 cycles:u: ffffffffa429ef48 [unknown] ([unknown]) ls 2364888 29303.010961: 1 cycles:u: ffffffffa4260133 [unknown] ([unknown]) ls 2364888 29303.010964: 5 cycles:u: ffffffffa429efad [unknown] ([unknown]) ls 2364888 29303.010967: 41 cycles:u: ffffffffa42a4586 [unknown] ([unknown]) ls 2364888 29303.010972: 435 cycles:u: ffffffffa429efe0 [unknown] ([unknown]) ls 2364888 29303.010978: 5142 cycles:u: 7f9b95bc2abf __GI___tunables_init+0x11f (/usr/lib64/ld-2.32.so) ls 2364888 29303.011006: 38551 cycles:u: ffffffffa4290f61 [unknown] ([unknown]) ls 2364888 29303.011486: 238234 cycles:u: 7f9b95bb7741 _dl_relocate_object+0xa71 (/usr/lib64/ld-2.32.so) ls 2364888 29303.011937: 415870 cycles:u: 7f9b95a1c80e __strcoll_l+0xe (/usr/lib64/libc-2.32.so) $ Before: $ perf script --dsos /usr/lib64/libc-2.32.so |& head -5 Error: unknown option `dsos' Usage: perf script [<options>] or: perf script [<options>] record <script> [<record-options>] <command> or: perf script [<options>] report <script> [script-args] $ After: $ perf script --dsos /usr/lib64/libc-2.32.so ls 2364888 29303.011937: 415870 cycles:u: 7f9b95a1c80e __strcoll_l+0xe (/usr/lib64/libc-2.32.so) $ Signed-off-by: Jin Yao <yao.jin@linux.intel.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Jin Yao <yao.jin@intel.com> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lore.kernel.org/lkml/20210124232750.19170-2-yao.jin@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
