From 270bbbe80d82fad8b698d0b407eb3ad67cc3492b Mon Sep 17 00:00:00 2001 From: Li Zefan Date: Thu, 17 Sep 2009 16:34:51 +0800 Subject: [PATCH] perf tools: Increase MAX_EVENT_LENGTH The name length of some trace events is longer than 30, like sys_enter_sched_get_priority_max and ext4_mb_discard_preallocations. Passing those events to perf-record will fail, try: # ./perf record -f -e syscalls:sys_enter_sched_get_priority_max -F 1 -a Signed-off-by: Li Zefan Acked-by: Frederic Weisbecker Cc: Peter Zijlstra LKML-Reference: <4AB1F4AB.7050205@cn.fujitsu.com> Signed-off-by: Ingo Molnar --- tools/perf/util/parse-events.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/perf/util/parse-events.c b/tools/perf/util/parse-events.c index 034245e4681..910283cbbc8 100644 --- a/tools/perf/util/parse-events.c +++ b/tools/perf/util/parse-events.c @@ -145,7 +145,7 @@ static int tp_event_has_id(struct dirent *sys_dir, struct dirent *evt_dir) (strcmp(evt_dirent.d_name, "..")) && \ (!tp_event_has_id(&sys_dirent, &evt_dirent))) -#define MAX_EVENT_LENGTH 30 +#define MAX_EVENT_LENGTH 512 int valid_debugfs_mount(const char *debugfs) { -- 2.20.1
