perf test vmlinux: Clarify which -v lines are errors or warning
When the 'perf test -v vmlinux' test fails, it is not clear which of the lines are errors or warnings, clarify that adding ERR/WARN prefixes: # perf test -F -v 1 1: vmlinux symtab matches kallsyms : --- start --- Looking at the vmlinux_path (8 entries long) Using /lib/modules/4.8.0-rc4+/build/vmlinux for symbols ERR : 0xffffffffb7001000: diff name v: xen_hypercall_set_trap_table k: hypercall_page WARN: 0xffffffffb7077970: diff end addr for aesni_gcm_dec v: 0xffffffffb707a2f2 k: 0xffffffffb7077a02 WARN: 0xffffffffb707a300: diff end addr for aesni_gcm_enc v: 0xffffffffb707cc03 k: 0xffffffffb707a392 WARN: 0xffffffffb707f950: diff end addr for aesni_gcm_enc_avx_gen2 v: 0xffffffffb7084ef6 k: 0xffffffffb707f9c3 WARN: 0xffffffffb7084f00: diff end addr for aesni_gcm_dec_avx_gen2 v: 0xffffffffb708a691 k: 0xffffffffb7084f73 WARN: 0xffffffffb708aa10: diff end addr for aesni_gcm_enc_avx_gen4 v: 0xffffffffb708f844 k: 0xffffffffb708aa83 WARN: 0xffffffffb708f850: diff end addr for aesni_gcm_dec_avx_gen4 v: 0xffffffffb709486f k: 0xffffffffb708f8c3 ERR : 0xffffffffb71a6e50: diff name v: perf_pmu_commit_txn.part.98 k: perf_pmu_cancel_txn.part.97 ERR : 0xffffffffb752e480: diff name v: wakeup_expire_count_show.part.5 k: wakeup_active_count_show.part.7 ERR : 0xffffffffb76e8d00: diff name v: phys_switch_id_show.part.11 k: phys_port_name_show.part.12 WARN: Maps only in vmlinux: ffffffffb7d7d000-ffffffffb7eeaac8 117d000 [kernel].init.text ffffffffb7eeaac8-ffffffffc03ad000 12eaac8 [kernel].exit.text WARN: Maps in vmlinux with a different name in kallsyms: WARN: Maps only in kallsyms: ---- end ---- vmlinux symtab matches kallsyms: FAILED! # Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Masami Hiramatsu <mhiramat@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/n/tip-n5ml8m7y9x8kzvxt09ipku88@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
