To control the way event information is printed, the user should call a set of functions in a specific sequence. These APIs are reimplemented to provide a more simple interface for printing event information. Removed APIs: tep_print_event_task() tep_print_event_time() tep_print_event_data() tep_event_info() tep_is_latency_format() tep_set_latency_format() tep_data_latency_format() tep_set_print_raw() A new API for printing event information is introduced: void tep_print_event(struct tep_handle *tep, struct trace_seq *s, struct tep_record *record, const char *fmt, ...); where "fmt" is a printf-like format string, followed by the event fields to be printed. Supported fields: TEP_PRINT_PID, "%d" - event PID TEP_PRINT_CPU, "%d" - event CPU TEP_PRINT_COMM, "%s" - event command string TEP_PRINT_NAME, "%s" - event name TEP_PRINT_LATENCY, "%s" - event latency TEP_PRINT_TIME, %d - event time stamp. A divisor and precision can be specified as part of this format string: "%precision.divisord". Example: "%3.1000d" - divide the time by 1000 and print the first 3 digits before the dot. Thus, the time stamp "123456000" will be printed as "123.456" TEP_PRINT_INFO, "%s" - event information. TEP_PRINT_INFO_RAW, "%s" - event information, in raw format. Example: tep_print_event(tep, s, record, "%16s-%-5d [%03d] %s %6.1000d %s %s", TEP_PRINT_COMM, TEP_PRINT_PID, TEP_PRINT_CPU, TEP_PRINT_LATENCY, TEP_PRINT_TIME, TEP_PRINT_NAME, TEP_PRINT_INFO); Output: ls-11314 [005] d.h. 185207.366383 function __wake_up Signed-off-by: Tzvetomir Stoyanov Cc: Andrew Morton Cc: Jiri Olsa Cc: Namhyung Kim Cc: linux-trace-devel@vger.kernel.org Cc: Patrick McLean Link: http://lore.kernel.org/linux-trace-devel/20190801074959.22023-2-tz.stoyanov@gmail.com Link: http://lore.kernel.org/lkml/20190805204355.041132030@goodmis.org Signed-off-by: Steven Rostedt (VMware) Signed-off-by: Arnaldo Carvalho de Melo --- tools/lib/traceevent/event-parse-api.c | 40 --- tools/lib/traceevent/event-parse-local.h | 4 - tools/lib/traceevent/event-parse.c | 322 +++++++++++++---------- tools/lib/traceevent/event-parse.h | 29 +- tools/perf/builtin-kmem.c | 3 +- tools/perf/util/sort.c | 3 +- tools/perf/util/trace-event-parse.c | 2 +- 7 files changed, 203 insertions(+), 200 deletions(-) diff --git a/tools/lib/traceevent/event-parse-api.c b/tools/lib/traceevent/event-parse-api.c index 988587840c80..4faf52a65791 100644 --- a/tools/lib/traceevent/event-parse-api.c +++ b/tools/lib/traceevent/event-parse-api.c @@ -302,33 +302,6 @@ void tep_set_local_bigendian(struct tep_handle *tep, enum tep_endian endian) tep->host_bigendian = endian; } -/** - * tep_is_latency_format - get if the latency output format is configured - * @tep: a handle to the tep_handle - * - * This returns true if the latency output format is configured - * If @tep is NULL, false is returned. - */ -bool tep_is_latency_format(struct tep_handle *tep) -{ - if (tep) - return (tep->latency_format); - return false; -} - -/** - * tep_set_latency_format - set the latency output format - * @tep: a handle to the tep_handle - * @lat: non zero for latency output format - * - * This sets the latency output format - */ -void tep_set_latency_format(struct tep_handle *tep, int lat) -{ - if (tep) - tep->latency_format = lat; -} - /** * tep_is_old_format - get if an old kernel is used * @tep: a handle to the tep_handle @@ -344,19 +317,6 @@ bool tep_is_old_format(struct tep_handle *tep) return false; } -/** - * tep_set_print_raw - set a flag to force print in raw format - * @tep: a handle to the tep_handle - * @print_raw: the new value of the print_raw flag - * - * This sets a flag to force print in raw format - */ -void tep_set_print_raw(struct tep_handle *tep, int print_raw) -{ - if (tep) - tep->print_raw = print_raw; -} - /** * tep_set_test_filters - set a flag to test a filter string * @tep: a handle to the tep_handle diff --git a/tools/lib/traceevent/event-parse-local.h b/tools/lib/traceevent/event-parse-local.h index 09aa142f7fdd..6e58ee1fe7c8 100644 --- a/tools/lib/traceevent/event-parse-local.h +++ b/tools/lib/traceevent/event-parse-local.h @@ -28,8 +28,6 @@ struct tep_handle { enum tep_endian file_bigendian; enum tep_endian host_bigendian; - int latency_format; - int old_format; int cpus; @@ -70,8 +68,6 @@ struct tep_handle { int ld_offset; int ld_size; - int print_raw; - int test_filters; int flags; diff --git a/tools/lib/traceevent/event-parse.c b/tools/lib/traceevent/event-parse.c index 3e83636076b2..d1085aab9c43 100644 --- a/tools/lib/traceevent/event-parse.c +++ b/tools/lib/traceevent/event-parse.c @@ -5212,24 +5212,20 @@ static void pretty_print(struct trace_seq *s, void *data, int size, struct tep_e } } -/** - * tep_data_latency_format - parse the data for the latency format - * @tep: a handle to the trace event parser context - * @s: the trace_seq to write to - * @record: the record to read from - * +/* * This parses out the Latency format (interrupts disabled, * need rescheduling, in hard/soft interrupt, preempt count * and lock depth) and places it into the trace_seq. */ -void tep_data_latency_format(struct tep_handle *tep, - struct trace_seq *s, struct tep_record *record) +static void data_latency_format(struct tep_handle *tep, struct trace_seq *s, + char *format, struct tep_record *record) { static int check_lock_depth = 1; static int check_migrate_disable = 1; static int lock_depth_exists; static int migrate_disable_exists; unsigned int lat_flags; + struct trace_seq sq; unsigned int pc; int lock_depth = 0; int migrate_disable = 0; @@ -5237,6 +5233,7 @@ void tep_data_latency_format(struct tep_handle *tep, int softirq; void *data = record->data; + trace_seq_init(&sq); lat_flags = parse_common_flags(tep, data); pc = parse_common_pc(tep, data); /* lock_depth may not always exist */ @@ -5264,7 +5261,7 @@ void tep_data_latency_format(struct tep_handle *tep, hardirq = lat_flags & TRACE_FLAG_HARDIRQ; softirq = lat_flags & TRACE_FLAG_SOFTIRQ; - trace_seq_printf(s, "%c%c%c", + trace_seq_printf(&sq, "%c%c%c", (lat_flags & TRACE_FLAG_IRQS_OFF) ?
