[alsa-devel] [PATCH] ALSA: hda - fix broken HDMI jack detection after S3
The HDMI codec (an NVIDIA one in this case) forgot that its pins were unsol enabled, while it was suspended. Therefore jack detection was broken after S3. With this patch, we reenable the unsol events on resume, and also do an extra check afterwards, to see if the HDMI monitor was plugged/unplugged while in S3.

snd_hda_jack_set_dirty_all() is already called in hda_call_codec_resume(), and snd_hda_jack_report_sync() is called in the init callback.
The tester (who has the hardware) has gone for the day, so I can't really verify different scenarios right now, but after having looked at hda_call_codec_resume I see what you mean...
I do notice one difference though - the order. snd_hda_codec_resume_cache, which is what writes the unsol_enable verbs, should probably be before the set_dirty_all / report_sync. If not for anything else, so for the race condition of somebody plugging/unplugging the monitor after checking the jack but before the unsol is enabled.
Could it be that the card gives wrong info if unsol is not enabled, or perhaps needs SET_PIN_SENSE in that case? I don't know.
But yeah, I'll have to wait with this patch then until I've verified more things.
Thanks.

Calling snd_hda_jack_report_sync() in init means that all jacks are checked at first, then the caches are resumed. So this won't change ENABLE_UNSOL verb setups.
The bug report doesn't give any details, so it's hard to guess what actually doesn't work. alsa-info.sh output before and after suspend would be helpful to understand.

I'm not sure I'm following. Here's the order in hda_call_codec_resume:
snd_hda_jack_set_dirty_all() generic_hdmi_init -> snd_hda_jack_report_sync() - get_pin_sense snd_hda_codec_resume_cache() - set_unsol_enable

Sorry about that. The machine is not yet released, that's why.

Well, what I'm thinking now is rather to call snd_hda_jack_report_sync() generically in hda_call_codec_resume(). The call doesn't have to be in all places. Ditto for the initialization case. It'll clean up many lines.

From: Takashi Iwai tiwai@suse.de Subject: [PATCH] ALSA: hda - Call snd_hda_jack_report_sync() generically in hda_codec.c
Instead of calling the jack sync in the init callback of each codec, call it generically at initialization and resume. By calling it at the last of resume sequence, a possible race between the jack sync and the unsol event enablement in the current code will be closed, too.

From: Takashi Iwai tiwai@suse.de Subject: [PATCH] ALSA: hda - Call snd_hda_jack_report_sync() generically in hda_codec.c
Instead of calling the jack sync in the init callback of each codec, call it generically at initialization and resume. By calling it at the last of resume sequence, a possible race between the jack sync and the unsol event enablement in the current code will be closed, too.
