From 6ed2597883b1b03ca94f62f0cfe908314cba6d6b Mon Sep 17 00:00:00 2001 From: Andy Green Date: Fri, 13 Jun 2008 16:24:05 +0100 Subject: ALSA: ASoC: Don't block system resume On OpenMoko soc-audio resume is taking 700ms of the whole resume time of 1.3s, dominated by writes to the codec over I2C. This patch shunts the resume guts into a workqueue which then is done asynchronously. The "card" is locked using the ALSA power state APIs as suggested by Mark Brown. [Added fix for race with resume to suspend and fixed a couple of nits from checkpatch -- broonie.] Signed-off-by: Andy Green Signed-off-by: Mark Brown Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela --- include/sound/soc.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include/sound/soc.h') diff --git a/include/sound/soc.h b/include/sound/soc.h index 1f5c6218100..340223a8f24 100644 --- a/include/sound/soc.h +++ b/include/sound/soc.h @@ -510,6 +510,7 @@ struct snd_soc_device { struct snd_soc_codec *codec; struct snd_soc_codec_device *codec_dev; struct delayed_work delayed_work; + struct work_struct deferred_resume_work; void *codec_data; }; -- cgit v1.2.3-70-g09d2
