Change the ftrace events to also print the component name, to make it clear which part of the code is involved. This requires changing the passed value from a struct snd_soc_card, where the DAPM context is not kwown, to a struct snd_soc_dapm_context where it is obviously known but the a card pointer is also available. With this change, the resulting trace becomes: aplay-247 [000] 1436.357332: snd_soc_bias_level_start: card=vscn-2046 component=(none) val=1 aplay-247 [000] 1436.357338: snd_soc_bias_level_done: card=vscn-2046 component=(none) val=1 aplay-247 [000] 1436.357340: snd_soc_bias_level_start: card=vscn-2046 component=(none) val=2 aplay-247 [000] 1436.357343: snd_soc_bias_level_done: card=vscn-2046 component=(none) val=2 kworker/u8:4-215 [000] 1436.357437: snd_soc_bias_level_start: card=vscn-2046 component=ff560000.codec val=1 kworker/u8:5-231 [000] 1436.357518: snd_soc_bias_level_start: card=vscn-2046 component=ff320000.i2s val=1 kworker/u8:5-231 [000] 1436.357523: snd_soc_bias_level_done: card=vscn-2046 component=ff320000.i2s val=1 kworker/u8:5-231 [000] 1436.357526: snd_soc_bias_level_start: card=vscn-2046 component=ff320000.i2s val=2 kworker/u8:5-231 [000] 1436.357528: snd_soc_bias_level_done: card=vscn-2046 component=ff320000.i2s val=2 kworker/u8:4-215 [000] 1436.383217: snd_soc_bias_level_done: card=vscn-2046 component=ff560000.codec val=1 kworker/u8:4-215 [000] 1436.383221: snd_soc_bias_level_start: card=vscn-2046 component=ff560000.codec val=2 kworker/u8:4-215 [000] 1436.383231: snd_soc_bias_level_done: card=vscn-2046 component=ff560000.codec val=2 kworker/u8:5-231 [000] 1436.383468: snd_soc_bias_level_start: card=vscn-2046 component=ff320000.i2s val=3 kworker/u8:5-231 [000] 1436.383472: snd_soc_bias_level_done: card=vscn-2046 component=ff320000.i2s val=3 kworker/u8:4-215 [000] 1436.383503: snd_soc_bias_level_start: card=vscn-2046 component=ff560000.codec val=3 kworker/u8:4-215 [000] 1436.383513: snd_soc_bias_level_done: card=vscn-2046 component=ff560000.codec val=3 Signed-off-by: Luca Ceresoli --- include/trace/events/asoc.h | 29 ++++++++++++++++------------- sound/soc/soc-dapm.c | 4 ++-- 2 files changed, 18 insertions(+), 15 deletions(-) diff --git a/include/trace/events/asoc.h b/include/trace/events/asoc.h index 4d8ef71090af..b7ac7f100bb4 100644 --- a/include/trace/events/asoc.h +++ b/include/trace/events/asoc.h @@ -17,38 +17,41 @@ struct snd_soc_card; struct snd_soc_dapm_widget; struct snd_soc_dapm_path; -DECLARE_EVENT_CLASS(snd_soc_card, +DECLARE_EVENT_CLASS(snd_soc_dapm, - TP_PROTO(struct snd_soc_card *card, int val), + TP_PROTO(struct snd_soc_dapm_context *dapm, int val), - TP_ARGS(card, val), + TP_ARGS(dapm, val), TP_STRUCT__entry( - __string( name, card->name ) - __field( int, val ) + __string( card_name, dapm->card->name) + __string( comp_name, dapm->component ? dapm->component->name : "(none)") + __field( int, val) ), TP_fast_assign( - __assign_str(name, card->name); + __assign_str(card_name, dapm->card->name); + __assign_str(comp_name, dapm->component ? dapm->component->name : "(none)"); __entry->val = val; ), - TP_printk("card=%s val=%d", __get_str(name), (int)__entry->val) + TP_printk("card=%s component=%s val=%d", + __get_str(card_name), __get_str(comp_name), (int)__entry->val) ); -DEFINE_EVENT(snd_soc_card, snd_soc_bias_level_start, +DEFINE_EVENT(snd_soc_dapm, snd_soc_bias_level_start, - TP_PROTO(struct snd_soc_card *card, int val), + TP_PROTO(struct snd_soc_dapm_context *dapm, int val), - TP_ARGS(card, val) + TP_ARGS(dapm, val) ); -DEFINE_EVENT(snd_soc_card, snd_soc_bias_level_done, +DEFINE_EVENT(snd_soc_dapm, snd_soc_bias_level_done, - TP_PROTO(struct snd_soc_card *card, int val), + TP_PROTO(struct snd_soc_dapm_context *dapm, int val), - TP_ARGS(card, val) + TP_ARGS(dapm, val) ); diff --git a/sound/soc/soc-dapm.c b/sound/soc/soc-dapm.c index bffeea80277f..7e8a2a5312f5 100644 --- a/sound/soc/soc-dapm.c +++ b/sound/soc/soc-dapm.c @@ -725,7 +725,7 @@ static int snd_soc_dapm_set_bias_level(struct snd_soc_dapm_context *dapm, struct snd_soc_card *card = dapm->card; int ret = 0; - trace_snd_soc_bias_level_start(card, level); + trace_snd_soc_bias_level_start(dapm, level); ret = snd_soc_card_set_bias_level(card, dapm, level); if (ret != 0) @@ -739,7 +739,7 @@ static int snd_soc_dapm_set_bias_level(struct snd_soc_dapm_context *dapm, ret = snd_soc_card_set_bias_level_post(card, dapm, level); out: - trace_snd_soc_bias_level_done(card, level); + trace_snd_soc_bias_level_done(dapm, level); return ret; }
