suspend2ram regression in snd_hda_intel

Mainline commit 785f857d1cb0856b612b46a0545b74aa2596e44a ("ALSA: hda - Set codec to D3 forcibly even if not used") breaks sound for my notebook (thinkpad x220),
looks like codec cannot wake from power-save state after resume. After reverting looks like all works fine.

how to reproduce:
* unplug the power cord (to enable hda power safe mode)
* play something and stop
* wait until the background noise disappears (codec went into power-save mode)
* suspend
* resume
* play something again and hear the silence

Bump

BTW, I don't see any locks around hda power-save code, for example hda_power_work() reads codec->power_on and codec->power_count without any locks. This seems racy.

It's a weekend, so don't expect quick responces from any normal person :)

Which 3.4-rc did you try? There was a known problem with this codec regarding the power-up sequence, but this should have been fixed in the very recent version.

If the latest Linus tree still shows the problem, try sound git tree master or for-next branch.
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git

Then attach alsa-info.sh output (run with --no-upload option) before and after S3 (i.e. working and non-working states).

Yeah, we may add an extra spinlock. But it's not too critical for the whole operation, so I didn't care much so far. At most, you'll miss one power-save cycle. Maybe a good time to fix it now for 3.5.

thanks,

Takashi

Yeah, sorry. In this country a mess with holidays and weekends.

Bug still in latest v3.4-rc6.
This is serious degradation since v3.3, so I hope it will be fixed before release.

I don't see there anything related to this problem. Bug is still there. It's 100% reproductible and disappears after reverting that commit. Looks like driver missed one power-up cycle after system-resume, after second power-save down/up cycle all work fine.

see attachments (kernel is v3.4-rc6 with changes from your branch)

start mplayer (work fine)
alsa-info.sh -> alsa-info.before
stop mplayer
suspend
resume
start mplayer (doesn't work)
alsa-info.sh -> alsa-info.after
stop mplayer
wait a second
start mplayer (work fine)

I'm afraid this code can easily miss one power-up cycle and stays in power-save mode. This can be unrelated to my problem, but from my point of view this is very careless. For example snd_hda_power_up() can easily race with hda_power_work().

OK. Could you try to pass model=auto and see whether it changes the behavior? I've checked only the auto-parser mode recently. It might be just the static quirk that got broken.

Note that the mixer elements will be renamed by this, so make sure that you adjust the mixer before testing S3.

FWIW, the below is an ad hoc fix. If this works for you, I'll queue it up for 3.4 kernel.

thanks,

Takashi

Subject: [PATCH] ALSA: hda - Fix S3 regression on Thinkpad X220

The commit [785f857d: ALSA: hda - Set codec to D3 forcibly even if not used] caused an S3 regression on Lenovo Thinkpad X220. The codec stays in D3 even after the resume by some reason.

As a simple workaround, just avoid the new behavior by that commit, i.e. going to D3 forcibly, for these Conexant codec chips.

1.7.9.2

Of course it helps, but this isn't "fix" at all!
Right fix follows...

This fixes regression in shd-hda-codec after 785f857d1cb0856b612b46a0545b74aa2 ("ALSA: hda - Set codec to D3 forcibly even if not used")

hda_set_power_state() call must be explicitly protected against recursive snd_hda_power_up/down() calls, otherwise it accidentally switches device into D0 right before suspend. As result after resume sound device stays in D3 state and does not works because driver believes that the device is on already.

Hrm, does this really fix your problem? The path is called only during the suspend. Then, in the resume path, the codec is all powered up anyway.

If the race between the leftover power-save work is really a culprit, the fix would be just calling cancel_delayed_work_sync() before that point...

thanks,

This fixes my problem: during suspend hda_set_power_state() calls snd_hda_power_up() it set codec->power_on = 1 and switches device into D0. At S3 resume codec->power_on == 1 but all devices actually in D3 state. As result on resume path device stays in D3, but after one power-save cycle all works again.

Race was always there, my problem was caused by commit which mentioned above.

Whole this code is very racy, someone needs to fix it.

Ah, thanks, that explains a lot.

Then it'd be actually better to revert the commit instead of another hack to paper over the nasty reincarnation.

The power-state change there shouldn't be involved with the whole power-up sequence. It should have been a simple "go-to-D3" sequence. But this would need the assurance that the controller side is ready, etc, and not too trivial to write with the current code base.

So, the right fix would be either implementing a straight hda_set_power_state() code without any power-up sequence but only the sanity check of the controller side, or fixing the original problem of ALC269 differently, e.g. by always resuming immediately at the resume callback but immediately performing the power-saving work.

In either way, it's too late for 3.4 kernel. And the original problem is no critical issue in comparison with this regression. So, a revert would be the best thing we can do for now, IMO.

Yeah, I know. I'll cook it up for 3.5 kernel.

thanks,

Takashi
