Possible fix for snd-hda-intel model=no-jd failing since ~linux-3.9-rc1

Possible fix for snd-hda-intel model=no-jd failing since ~linux-3.9-rc1

[Adam Richter]

[-- Attachment #1: Type: text/plain, Size: 3419 bytes --]

Hi.

This is a bug and suggested temporary fix that I originally posted to the linux-sound mailing list about a month and a half ago.  I am grateful to Takashi Awai for informing me after my follow-up inquiry about it today that I should submit it to the alsa-devel mailing list instead.  Please feel free to redirect me further if appropriate.  I did not notice any contact information for sound/pci/hda in
linux-3.16-rc4/MAINATINERS.

Anyhow, here is the bug report and a one line proposed temporary fix.


The "model=no-jd" argument has not initialized the analog audio output jack correctly for me since linux-3.9-rc1 (if I recall correctly) through linux-3.17-rc4, although I have not tried every release candidate in between.

The symptom is that, on a computer with an analog audio output jack
that has incorrect jack sense (a hardware bug), audio output is completely muted until I physically replug the cable, even though I specified "model=no-jd" as an argument to the snd-hda-intel kernel module, which is supposed to cause the kernel to ignore the jack sense reported by hardware and just drive the audio output even if the hardware jack sense indicates nothing is plugged in.  This problem did not occur until approximate Linux 3.9-rc1.

I have found a few single line workarounds that work, of which my
favorite is the following (also attached to this email, in case any
mailer subjects this message to reformatting), because it does not add
code to anything that gets called frequently.

I consider this a workaround rather than than a perfect fix, because I
think the underlying problem seems to be some kind of initialization
order issue that I don't fully understand.  Basically, by the time
jack->phantom_jack was being set, some caller had already called
jack_detect_update(), which loaded the incorrect jack sense result
from hardware and cleared jack->jack_dirty, so the jack sense would
not be set again.  At least that is what I think the underlying
problem probably is.

Also, if a change like this is to be integrated, I'd like to know if
it might be better for the line that I added to be:

          jack->phantom_jack = !is_jack_detectable(codec, nid);

...which is what add_jack_kctl does (not sure why add_jack_kctls does
not, by the way, at the risk of making a spectacle of my ignorance).
My doubt about this approach is that perhaps is_jack_detectable()
relies on some initialization that has not occurred at that point.

Anyhow, I'd like to get the process started of either pushing this
change upstream or quickly developing a more correct fix.  If a more
correct fix does not become apparent in the next few days, I would
recommend pushing the workaround upstream now until some future code
cleanup, so people will no longer be effected by the bug.

Any technical input or advice on how to proceed is welcome.  Thanks
for taking the time to consider this.

Could you give alsa-info.sh output on your machine?  Otherwise it's
difficult to analyze.

Speaking of your patch: add_jack_kctl() itself has a check of
is_jack_detectable() for phantom jacks, so basically this shouldn't
make any difference.  So we need to check more deeply why this change
is really needed.


thanks,

Takashi

Hi Adam,

Interesting problem. Could you submit alsa-info ( 
http://www.alsa-project.org/alsa-info.sh ) and point us to it? It makes 
it possible to run the code in an emulator.

A lot of things changed with 3.9, so that makes sense. Btw, 
"model=no-jd" works only for specific machines. You can use the hint 
"jack-detect=0" instead.

Yes, this would probably be better.

I guess that somehow snd_hda_jack_enable_callback gets called for the 
phantom jack, but I'm not sure exactly how (alsa-info would help).

Nevertheless I'm attaching a patch. I assume it also resolves your problem?

Takashi, what do you think of the attached patch?

To make sure we don't enable unsol events on phantom jacks,
we move the logic for determining what a phantom jack is to
snd_hda_jack_tbl_new.

I'd comment only after I see alsa-info.sh output.  The patch above
just makes it phantom without changing the name suffix, which looks
bogus.  So, I prefer fixing in a better way.

Of course, more important to know why it happens and how.

This doesn't look good.  The pincfg isn't always reliable at this
point.  The pin connection check is used in add_jack_kctl() in the
current code just because its only caller is snd_hda_jack_add_kctls(),
which takes the pincfg explicitly.  But snd_hda_jakc_tbl_new() itself
is neutral about the pincfg.

And, another problem is that it'll result in a phantom jack secretly
without adding a proper name suffix.

In anyway, for catching such a bug, maybe we should put a WARN_ON() at
snd_hda_jack_detect_enable_callback() like the patch below.

Are you saying that codec->user_pins/driver_pins/init_pins might not be 
properly initialized at this point? If so, maybe we should instead warn 
on somebody calling snd_hda_jack_tbl_new too early?

Are you sure?

snd_hda_jack_add_kctl is called from add_jack_kctl and the hdmi driver.
Add_jack_kctl now uses the phantom_jack flag (as initialized by 
jack_new) to create a proper name, i e, no difference.
generic_hdmi_build_jack should probably replace its "is_jack_detectable" 
call to check the phantom_jack flag for consistency, but for all common 
cases it's no change there either.

Remember that enable_callback is sometimes called for non-pin nodes, 
such as the afg node in the sigmatel driver. Calling is_jack_detectable 
on non-pin nodes seems wrong to me.

No, the hda_jack stuff itself isn't necessarily depending on the
pincfg deeply.  For example, is_jack_detectable() doesn't check the
pin location (although it checks MISC_NO_PRESENCE bit as an
exception).

Hm, OK, that won't happen.  But my point is that it's wrong to check
the phantom flag there.

OK, then it's an overkill.

Looking at the alsa-info.sh output, the problem is that IDT codec
parser creates jack detection for the power-control before the generic
parser.  There is also a wrong logic in stac_init_power_map()...

An untested fix is below.

Is there a good reason why the hda_jack stuff should not depend on pincfg?

Also, if we keep the detection in snd_hda_jack_tbl_new, we could change 
all other calls to is_jack_detectable to !jack->phantom_jack instead.

Because the pincfg isn't always reliable, as you know ;)

Well, I think is_jack_detectable() is rather a helper to be moved to
hda_codec.c, i.e. its functionality is independent from what else in
hda_jack.c.  In other words, I don't think we want to tie it with
hda_jack stuff (at least in the current form of hda_jack.c
infrastructure).

I guess this was blocked by the mail server due to a too big

BTW, a part of the messes is the restriction of hda_jack stuff:
currently it supports only one callback per jack.  If we can add
multiple callbacks and actions to a jack, the code in patch_sigmatel.c
would be come much easier.  But this is a step after fixing the bug
quickly.

Re: Possible fix for snd-hda-intel model=no-jd failing since ~linux-3.9-rc1

Hi, Takashi.

I confirm that your patch, quoted below, eliminated the symptom.

Please feel free to ask me to test other patches related to this problem.

Also, by the way, it appears that linux-3.17-rc4's Intel "high defintiion audio" driver, regardless of whether this patch is applied, no longer shows Linux input subsystem devices for analog audio jack sense, although it does provide such a device for HDMI jack sense.  If that's a bug, it's completely separate, but I mention it here in case it's relevant to integrating a fix to this issue.

Thanks to you and David for your prompt and careful attention this bug once I brought it to this mailing list.

Hi, again, Takashi.

A few minute ago, I wrote a side comment that you should ignore, which was the following:

>Also, by the way, it appears that linux-3.17-rc4's Intel "high defintiion audio"
> driver, regardless of whether this patch is applied, no

In Linux 3.17-rc4, reloading the snd-hda-intel module without "model=no-jd" results in those input devices being created.  So, it is not a bug.  In fact, I think is completely correct and an improvement that mode=no-jd now causes the jack sense Linux input layer devices not to be created, which should make it easier for userspace to detect and adapt to this situation.

Sorry for the distraction.

Good to hear.  I merged the patch now for-linus branch.

OK.  I have attached it.  In a few places, I replaced text with "[DELETED]" to avoid identifying the product.

Right. This is some kind of initialization order problem where the following data flow fails: codec->no_jack_detect ==> jack->phantom_jack ==> jack->pin_sense.  The Intel driver has a lot of "codec" sub-drivers, and I wasn't sure if would would really be practical for me to understand and get the relevant codec maintainers to approve if necessary.  The fix I proposed is something I see as a temporary very low overhead workaround (only adds a few instructions, and only at initialization) until a correct fix is implemented.  However, if this can be fixed properly quicly enoughtso avoid the need for a temporary workaround, that would be great.

Thank you for your analysis of this.

Is this enumerated codec inside vm since node 0x18 and node 0x19 does not
like the real idt coded ?

It's real hardware.

Thanks for your attention to this problem.

It is strange that your hardware have the desktop pin layout plus two

Possible fix for snd-hda-intel model=no-jd failing since ~linux-3.9-rc1

[adam richter]

[-- Attachment #1: Type: text/plain, Size: 2983 bytes --]

Hi.

Please feel free to redirect me to another email address.  I did not
notice any contact information for sound/pci/hda in
linux-3.16-rc4/MAINATINERS.

The "model=no-jd" argument has not initialized correctly for me for
linux-3.9-rc1 (if I recall correctly) through linux-3.16-rc4, although
I have not tried every release candidate in between.

The symptom is that, on a computer with an analog audio output jack
that usually does not correctly sense a device is plugged in, audio
output is completely muted until I physically replug the cable, even
though I specified "model=no-jd" as an argument to the snd-hda-intel
kernel module, which is supposed to cause the kernel to ignore the
jack sense reported by hardware and just drive the audio output even
if the hardware jack sense indicates nothing is plugged in.

I have found a few single line workarounds that work, of which my
favorite is the following (also attached to this email, in case any
mailer subjects this message to reformatting), because it does not add
code to anything that gets called frequently.

I consider this a workaround rather than than a perfect fix, because I
think the underlying problem seems to be some kind of initialization
order issue that I don't fully understand.  Basically, by the time
jack->phantom_jack was being set, some caller had already called
jack_detect_update(), which loaded the incorrect jack sense result
from hardware and cleared jack->jack_dirty, so the jack sense would
not be set again.  At least that is what I think the underlying
problem probably is.

Also, if a change like this is to be integrated, I'd like to know if
it might be better for the line that I added to be:

          jack->phantom_jack = !is_jack_detectable(codec, nid);

...which is what add_jack_kctl does (not sure why add_jack_kctls does
not, by the way, at the risk of making a spectacle of my ignorance).
My doubt about this approach is that perhaps is_jack_detectable()
relies on some initialization that has not occurred at that point.

Anyhow, I'd like to get the process started of either pushing this
change upstream or quickly developing a more correct fix.  If a more
correct fix does not become apparent in the next few days, I would
recommend pushing the workaround upstream now until some future code
cleanup, so people will no longer be effected by the bug.

Any technical input or advice on how to proceed is welcome.  Thanks
for taking the time to consider this.

Adam Richter

Hello, Jaroslav and Takashi.

Could you please tell me what I need to do to get this one line change
interegrated so that it will make its way to the mailing kernel?

I apologize if I was unclear in my previous message that I do want to
see this patch integrated now until someone develops a better
solution.

This bug is a regression that began around Linux 3.9-rc1.  I described
it and a one line fix over two months ago on the linux-sound mailing
list.  I have just verified that the bug and the fix are still
applicable to newly released Linux 3.17.0-rc4, and that this change is
not already in git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git
or git://git.alsa-project.org/alsa-kernel.git .

For your convenience, I have included an attachment for this one line
patch against linux-3.17.0-rc4, although it is also shown in the text
below.

What do I need to do to get this fix on its way to upstream or get a
rejection with some kind of explanation (for example, maybe a better
fix is already in a git tree and will soon be sent to mainline)?

Thanks in advance for your attention to this, and, of course, thanks
for all of your contributions to Linux.

You're sending to a wrong list.  Please post to alsa-devel ML instead.
