From 56271170438df39c1b9a39c7aaf69010e6a4b59a Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 18 Jan 2018 10:28:14 -0300 Subject: [PATCH] perf tools: Use ui__error() for reporting --fields errors So that we can get it working for TUI, where using just pr_err() would end up making the message emitted to stderr to be erased by the TUI exit routine restoring the terminal to its previous state. Now we can see that trying to use a tracepoint field as one of the --field entries isn't working: # perf top --stdio --no-children -e syscalls:sys_enter_write --fields pid,sym,count Error: Unknown --fields key: `count' Usage: perf top [] --fields output field(s): overhead, period, sample plus all of sort keys # Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Namhyung Kim Cc: Wang Nan Link: https://lkml.kernel.org/n/tip-usy9hhy7umdd4bbblkn63t8w@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/util/sort.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/tools/perf/util/sort.c b/tools/perf/util/sort.c index 211e7f326b9f..2da4d0456a03 100644 --- a/tools/perf/util/sort.c +++ b/tools/perf/util/sort.c @@ -2887,10 +2887,10 @@ static int setup_output_list(struct perf_hpp_list *list, char *str) tok; tok = strtok_r(NULL, ", ", &tmp)) { ret = output_field_add(list, tok); if (ret == -EINVAL) { - pr_err("Invalid --fields key: `%s'", tok); + ui__error("Invalid --fields key: `%s'", tok); break; } else if (ret == -ESRCH) { - pr_err("Unknown --fields key: `%s'", tok); + ui__error("Unknown --fields key: `%s'", tok); break; } }
