[PATCH V1 1/4] ALSA: hda: fix controller cannot suspend when codec using jackpoll

[joakim.zhang]

From: Joakim Zhang <joakim.zhang@cixtech.com>

For current design, sync cancel jackpoll delayed work in
hda_codec_runtime_suspend(), sync means it will cancel pending
works, so jackpoll work would be called.
  hda_jackpoll_work()-->
      snd_hda_power_up_pm()-->
          if (!atomic_inc_not_zero(&codec->in_pm))
		return snd_hdac_power_up(codec);-->
		    pm_runtime_get_sync()

The point where cancel_delayed_work_sync() called not in_pm,
though it actually is. It will runtime resume codec device again,
the power usage_count increase 1, but it should be 0 when codec
is suspending, finally codec is in resume state, not suspended.

HDA controller as the parent of codec device, also cannot enter
suspend, this patch change to sync cancel jackpoll delayed work when
codec in_pm is set, so it will not resume codec again.

[PATCH V1 2/4] ALSA: hda: add no_pin_sense_update flag for jack detection

[joakim.zhang]

From: Joakim Zhang <joakim.zhang@cixtech.com>

snd_hda_jack_detect_* functions should be called when want to
detect then report jack status immediately, however it now called
from other points such as patch_ops.init which just want to
judge if the device is attached and no report behaviour.

Let take corner case into account:
1) device is de-attached before suspended, old pin sense is not present
2) attach the device when device in suspended
3) when codec resume back and the device is attached, it will update
   pin sense as present from codec init function (patch_ops.init),
   when it tries to read pin sense from jackpoll delayed work,
   the old pin sense would be present (but actaully it is not present),
   and the new pin sense also is present, so decides no changes, cause
   the device cannot be detected.

Add no_pin_sense_update flag to control if we need update the pin
sense when read the hardware pin sense.

[PATCH V1 3/4] ALSA: hda: disable jackpoll_in_suspend when system shutdown

[joakim.zhang]

From: Joakim Zhang <joakim.zhang@cixtech.com>

When do reboot test, kernel panic when system shutdown since
jackpoll delayed work tries to read registers via hda bus
but the drivers are all shut down.

The root cause is that when system shutdown but codec may in
runtime resume state, call runtime force suspend would trigger
jackpoll delayed work active again, finally cause the kernel
panic since it access registers with clocks/reset/power off.

Thanks for the patches.  Indeed the polling mode has been little cared
for now.  I'll comment / suggest in each patch reply.

That's too awkward...

I believe that, if the hda-codec doesn't set jackpoll_in_suspend flag,
we should simply disable the runtime PM.  Such a device is supposed to
be polling frequently (e.g. VIA codec) that conflicts with the runtime
PM.

For that, we can simply define the runtime_idle callback.

Another point is that hda_jackpoll_work() could simply use
snd_hda_power_up() and *_down() instead of snd_hda_power_up_pm() and
co.  We used *_pm variant because the function was called directly in
the init or the resume paths.  But we can call this only from the
work, then we can switch to the safer *_up/down() calls.  Then this
assures the runtime resume completion in the work without much races.

With those transitions, basically the cancel_delayed_work_sync() call
at hda_codec_runtime_suspend() can be dropped.  Also, the conditional
schedule_delayed_work() there, too; if we don't cancel, we don't need
reschedule, either.

So the (totally untested) PoC is something like below.
It contains also the fix corresponding to your patch 3, too.


thanks,

Takashi

I don't understand the situation well.  Do you mean "device" in the
steps 1/2/3 as a device to be connected to the jack, such as a
headphone, not the HD-audio codec device, right?

Even with that assumption, I still don't follow your logic fully...
Basically, when snd_hda_jack_report_sync() is called, this should
report the jack state changes.  I believe we should simply call
snd_hda_jack_report_sync() unconditionally, then schedule the jackpoll
work, as done in my PoC patch.

This one should be better with codec->jackpoll_interval = 0, set
before cancel_work_sync().  Then it'll guarantee that the jackpoll
work won't be called any more.

This needs a confirmation from Realtek.

That's too awkward...

I believe that, if the hda-codec doesn't set jackpoll_in_suspend flag,
we should simply disable the runtime PM.  Such a device is supposed to
be polling frequently (e.g. VIA codec) that conflicts with the runtime
PM.

For that, we can simply define the runtime_idle callback.

Another point is that hda_jackpoll_work() could simply use
snd_hda_power_up() and *_down() instead of snd_hda_power_up_pm() and
co.  We used *_pm variant because the function was called directly in
the init or the resume paths.  But we can call this only from the
work, then we can switch to the safer *_up/down() calls.  Then this
assures the runtime resume completion in the work without much races.

With those transitions, basically the cancel_delayed_work_sync() call
at hda_codec_runtime_suspend() can be dropped.  Also, the conditional
schedule_delayed_work() there, too; if we don't cancel, we don't need
reschedule, either.

So the (totally untested) PoC is something like below.
It contains also the fix corresponding to your patch 3, too.

[Joakim] Thanks Takashi for your cleanup, actually it's better to switch to the *_up/down() calls, I will test then feedback to you soon.

thanks,

Takashi

I don't understand the situation well.  Do you mean "device" in the
steps 1/2/3 as a device to be connected to the jack, such as a
headphone, not the HD-audio codec device, right?

[Joakim] Yes, you are right, what I mean is the device to be connected to the jack, what I tested is a headset.

Even with that assumption, I still don't follow your logic fully...
Basically, when snd_hda_jack_report_sync() is called, this should
report the jack state changes.  I believe we should simply call
snd_hda_jack_report_sync() unconditionally, then schedule the jackpoll
work, as done in my PoC patch.

[Joakim] Let me take realtek alc256 as an example,
hda_call_codec_resume()
    1)codec->patch_ops.resume(codec) // alc269_resume()
        codec->patch_ops.init(codec) // alc_init()
            spec->init_hook(codec) // alc256_init()
            snd_hda_jack_detect(codec, hp_pin) 
                    ....
                    snd_hda_jack_pin_sense()
                        jack_detect_update()
                            jack->pin_sense = read_pin_sense(codec, jack->nid, jack->dev_id);  // update jack->pin_sense here, but not report jack status
    2)hda_jackpoll_work(&codec->jackpoll_work.work)
            snd_hda_jack_poll_all(codec)
                 old_sense = get_jack_plug_state(jack->pin_sense);
                 jack_detect_update(codec, jack);
                 if (changes)
                      snd_hda_jack_report_sync(codec);

If the headset is not plugin before system suspending, so the jack->pin_sense = 0x0, plugin the headset when system in suspended state, system resume back, the jack->pin_sense update to 0x80000000 from codec patch_ops.init(), then jackpoll work get the old_sense = 0x80000000 (but actually it is not old sense before system suspending), and the current jack->pin_sense also 0x80000000 when calling jack_detect_update(), as a result there is no changes, finally not report the headset plugin event.

Is it logical to report jack status immediately when updating the jack pin sense? If not, the old pin sense can still be trusted?

Please correct me if anything misunderstanding, thanks, as a hda newer may not understood very deeply.

thanks,

Takashi

I confirm this issue exist in the original logic, but your PoC also fix this issue, I quite agree with your above point of view:
"I believe we should simply call  snd_hda_jack_report_sync() unconditionally, then schedule the jackpoll work,  as done in my PoC patch."

With your PoC patch, three issues(patch 1/2/3) have been solved simultaneously, please feel free to add my tested tag:

Hi Joakim,

Could you use alsa-info.sh to dump codec info to us?
Your platform was ARM Architecture. So, it's no PCI device. Right?

#The script was written for 2 main reasons:
# 1. Remove the need for the devs/helpers to ask several questions before we can easily help the user.
# 2. Allow newer/inexperienced ALSA users to give us all the info we need to help them.

#Set the locale (this may or may not be a good idea.. let me know)

Yes, our HDA controller under AXI bus based on ARM arch, so I'm a little worried whether some known fixup for pci not applied.

Attached log is dumped after the system boot with headset plugin, but the mic cannot be detected.

This usage will affect all ALC256.

Codec: Realtek ALC256
Address: 0
AFG Function Id: 0x1 (unsol 1)
Vendor Id: 0x10ec0256
Subsystem Id: 0x10ec0256   ==>  Could you assign this to 0x10EC129E ?  This codec SSID was provide from our AE. It's verb table.
Revision Id: 0x100002
No Modem Function Group found
Default PCM:

We can check Subsystem Id to let spec->en_3kpull_low = false.

Did you find anything from the log? Is it a potential issue?

You mean re-generate the verb table with SSID equal 0x10EC129E? But from the patch_realtek.c have not found any hook to fixup this SSID.

Maybe your platform need to set spec->en_3kpull_low to false.
If spec->en_3kpull_low = false will help you to get MIC JD.

Yes, but don't know what exact hardware design makes this difference, do you know it?

Indeed, it's better to add a board fixup, please ignore this patch, will upstream later after hda controller upstreamed.

I don't know. But FT(Phytium) platform was disable runtime suspend, it doesn't have this issue.
FT has not upstream his patch until now.

It can auto switch 'Headphone Playback Switch'/'Headphone Playback Volume' and
'Speaker Playback Switch'/'Speaker Playback Volume', when I plugin the headset or not,
but I have not found the related logic, could you please help clarify a bit?

Isn't it "Auto-Mute Mode"?  If it's set, the speaker is muted
automatically when the headphone/headset jack is plugged by the kernel
driver itself.

What strange is 'Auto-Mute Mode' would be disabled after headset plugin/out several times, don' t know the reason....
However, it seems that speaker and headphone/headset still can auto switch. Please see below mixer status.

"Auto-Mute Mode" is a software switch, and it means some program
must have turned it off explicitly.  e.g. the sound server like
pulseaudio or pipewire disables it.

> However, it seems that speaker and headphone/headset still can auto switch. Please see below mixer status.

Usually pulseaudio/pipewire takes over and does the switching.

OK, I see, I will dig into it, could you please tell me is there any other software switches in the mixers?

Any mixer program can change...  But basically the auto-mute is a task

I disable both pulseaudio and pipewire from the Debian, and enable the auto-mute, when the headset plugin but the switch not set correctly.
'Headphone Playback Switch'/'Headphone Playback Volume' not set, but 'Speaker Playback Switch'/'Speaker Playback Volume' enabled.
Are there any other possible reasons?

The mixer settings are exposed to user-space and user-space programs
can read or change them, sure.  But it's not clear what is your exact
purpose or goal, so I can't answer much better than that.

The auto-mute feature is implemented in the kernel driver level, so
that the automatic muting via jack plug can work without the sound
daemon.  The auto-muted state isn't exposed to user-space via ALSA
control API (mixer elements), and it looks as  if it were muted by the
hardware.  Actually there are hardware that do the auto-muting in the
hardware level, too.

Takashi, thanks for your details, I think what I want to know is what did in the kernel driver level for hp automute and mic autoswitch.

I am looking the code, it seems only update the pins and not update the mixer, right? So when the headset plugin, it will auto mute hp and auto switch to mic at the hardware level, users still need to update the mixer manually.

Further, is there any place in the hda codec driver level to update the mixers? AFAIK, for the ASoC driver, codec driver level would update some mixers dynamically based on the routing.

Thanks,
Joakim

Users don't need to update the mixer -- that's the whole point of the
driver auto-mute stuff.  When plugged, the speaker gets muted, and the
output is routed to the headphone jack with the formerly set headphone
volume and switch.  Even if you change the speaker volume/switch, it
has no effect as long as the jack is plugged.  When unplugged, the
headphone volume/switch can change but without any effect, too.

> Further, is there any place in the hda codec driver level to update the mixers? AFAIK, for the ASoC driver, codec driver level would update some mixers dynamically based on the routing.

The codec driver creates the mixer elements and handle them, yes.
Also, the virtual-master control influences on the volume of each
assigned output, too.

I have fully understood the auto-mute feature, one point you pointed out is very crucial,
" When plugged, the speaker gets muted, and the output is routed to the headphone jack with the **formerly** set headphone volume and switch."

So, the volume and switch of the both headphone and switch should be **formerly** set by user via ALSA API when auto-mute enabled, I tested and work normally.

The problem that is bothering me now is, I cannot find which thread try to control the mixers(switch/volume of headphone/speaker, auto-mute mode etc) via ALSA API, running with debian os.
