[alsa-devel] Hung task with trace after resume on kernel v3.7-rc6
Hello,
I have an Thinkpad X121e with the following soundcard: 00:01.1 Audio device [0403]: Advanced Micro Devices [AMD] nee ATI Wrestler HDMI Audio [Radeon HD 6250/6310] [1002:1314]

I added a fix recently to prevent a similar lockup but I missed the case where snd_hda_suspend is called from azx_reset_bus in turn called from snd_hda_suspend.
I'm torn between fixing this lockup and just avoiding this recursive call. Without the lockup, what state do we leave the codec in when this happens?
Am I understanding the scenario below correctly?
- do first half of suspend - verb exec error --> reset --- suspend --- resume (and queue work to suspend later - second half of suspend (Is this OK?)
Maybe a state machine of some sort could be added to manage the power state. It could notice the error and restart the suspend from the beginning. That way the codec suspend function is called again and a complete transition to suspended is performed.
Takashi, do you see a simple way of handling this?

I added a fix recently to prevent a similar lockup but I missed the case where snd_hda_suspend is called from azx_reset_bus in turn called from snd_hda_suspend.
I'm torn between fixing this lockup and just avoiding this recursive call. Without the lockup, what state do we leave the codec in when this happens?
Am I understanding the scenario below correctly?
- do first half of suspend
- verb exec error --> reset
--- suspend --- resume (and queue work to suspend later
- second half of suspend (Is this OK?)
Maybe a state machine of some sort could be added to manage the power state. It could notice the error and restart the suspend from the beginning. That way the codec suspend function is called again and a complete transition to suspended is performed.
Takashi, do you see a simple way of handling this?
I think we can ignore errors during suspend in general. It's not too critical in comparison with resume, and usually the suspend callback is only for improving the pop noise or such.
So, for this particular issue (at least the recursive suspend call), I think the easiest way is a patch like below. This is no ideal solution but would be good enough as a bandaid at this late stage for 3.7. Julian, could you check whether this works?
But, as long as I look at the code, it seems that currently we have no good protection against the suspend call during the power-saving suspend is being called. This should be fixed, but maybe we can do it for 3.8. A state machine can be a good implementation for improving these messes, yes.
thanks,
Takashi

Note that spurious responses won't be fixed by this patch at all. It's a different problem from the hung. The patch tried only avoiding the recursive suspend call.

OK, then this code path is irrelevant with the real suspend/resume, but it's in a normal power-saving path.
Could you try the patch below instead?
By the way, it seems like I get the traces every 120 seconds and not only once, forgot to mention that earlier.
The spurious call (or no proper reply for the verb) indicates that either the HD-audio controller or the HD-audio codec stalls. Is yours a machine with a discrete GPU? If so, and if you are using vga-switcheroo or anything manipulating the D-GPU, it's possibly the cause of the stall.

Could you try the patch below instead?
The patch did not apply against 3.7-rc6 but the patch below applied and let the trace disappear.
By the way, it seems like I get the traces every 120 seconds and not only once, forgot to mention that earlier.
The spurious call (or no proper reply for the verb) indicates that either the HD-audio controller or the HD-audio codec stalls. Is yours a machine with a discrete GPU? If so, and if you are using vga-switcheroo or anything manipulating the D-GPU, it's possibly the cause of the stall.
I just have an AMD-450 APU (an onboard GPU) with no vga-switcheroo or other things involved.
With best regards, Julian Wollrath

OK, then at least it can be added as a workaround.
But the spurious response still appears, right?

Hm, then something screwed up the communication...
At which moment do you see such a message? In other words, how to trigger the bug?

Yes, the spurious response still appears.

I suspend my system to ram or to disk. Then I resume it, everthing comes up again and then, aprrox 4s after the resume was initiated, the spurious response messages hit the dmesg for approx. 0.07s as you can see in my first message. Hopefully this answer the question.

Hm, then something screwed up the communication...
At which moment do you see such a message? In other words, how to trigger the bug?
I suspend my system to ram or to disk. Then I resume it, everthing comes up again and then, aprrox 4s after the resume was initiated, the spurious response messages hit the dmesg for approx. 0.07s as you can see in my first message. Hopefully this answer the question.
Hm, just got some messages, which did not appear before: [ 244.497999] snd_hda_intel 0000:00:14.2: wake-up capability disabled by ACPI [ 244.498063] snd_hda_intel 0000:00:14.2: enabling device (0000 -> 0002)
Do you have CONFIG_PM_RUNTIME=y? If yes, any difference when turn it off?
Also, apply the patch below so that we can see which device is actually stalling.

I have CONFIG_PM_RUNTIME=y, I will try it without it.
So, with CONFIG_PM_RUNTIME=n I get no spurious response messages.
OK, it's a good sign. What happens if you enable CONFIG_PM_RUNTIME again but set the option power_save_controller=0 for snd-hda-intel module?
Or, try the patch below.
There is one place left checking CONFIG_PM_RUNTIME in hda_intel.c, but I guess it's irrelevant. Let's see.
thanks,

--- From: Takashi Iwai tiwai@suse.de Subject: [PATCH] ALSA: hda - Limit runtime PM support only to known Intel chips
We've got a report that the runtime PM may make the codec the unresponsive on AMD platforms. Since the feature has been tested only on the recent Intel platforms, it's safer to limit the support to such devices for now.
This patch adds a new DCAPS bit flag indicating the runtime PM support, and mark it for Intel controllers.

Could you clear the patch and check whether power_save_controller=0 option also solves the issue?
If it works, the patch below should help. Give it a try.
The patch below does help, the spurious responses do not show up anymore.
Thank you very much for your help and your quick response, with best regards, Julian
From: Takashi Iwai tiwai@suse.de Subject: [PATCH] ALSA: hda - Limit runtime PM support only to known Intel chips
We've got a report that the runtime PM may make the codec the unresponsive on AMD platforms. Since the feature has been tested only on the recent Intel platforms, it's safer to limit the support to such devices for now.
This patch adds a new DCAPS bit flag indicating the runtime PM support, and mark it for Intel controllers.

Great, now I merged both fix patches to sound git tree. They'll be included in the next pull request.
