From e8c5fe101e55e4c45a2859cea2b4c374595f8867 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Mon, 21 Nov 2016 22:33:27 +0100 Subject: [PATCH] perf c2c report: Setup browser after opening perf.data Because of the early browser switch we won't get possible error messages, as it will clear the screen right after showing the message, e.g.: Before: $ sudo perf c2c report -d lcl $ After: $ sudo perf c2c report -d lcl File perf.data not owned by current user or root (use -f to override) $ $ ls -la perf.data -rw-------. 1 acme acme 26648 Nov 22 15:11 perf.data $ Signed-off-by: Jiri Olsa Tested-by: Arnaldo Carvalho de Melo Cc: Andi Kleen Cc: David Ahern Cc: Don Zickus Cc: Joe Mario Cc: Namhyung Kim Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1479764011-10732-3-git-send-email-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/builtin-c2c.c | 15 ++++++++------- 1 file changed, 8 insertions(+), 7 deletions(-) diff --git a/tools/perf/builtin-c2c.c b/tools/perf/builtin-c2c.c index c6d0dda594d9..15addb06d611 100644 --- a/tools/perf/builtin-c2c.c +++ b/tools/perf/builtin-c2c.c @@ -2535,13 +2535,6 @@ static int perf_c2c__report(int argc, const char **argv) if (c2c.stats_only) c2c.use_stdio = true; - if (c2c.use_stdio) - use_browser = 0; - else - use_browser = 1; - - setup_browser(false); - if (!input_name || !strlen(input_name)) input_name = "perf.data"; @@ -2568,6 +2561,7 @@ static int perf_c2c__report(int argc, const char **argv) pr_debug("No memory for session\n"); goto out; } + err = setup_nodes(session); if (err) { pr_err("Failed setup nodes\n"); @@ -2587,6 +2581,13 @@ static int perf_c2c__report(int argc, const char **argv) goto out_session; } + if (c2c.use_stdio) + use_browser = 0; + else + use_browser = 1; + + setup_browser(false); + err = perf_session__process_events(session); if (err) { pr_err("failed to process sample\n");
