[alsa-devel] [BUG] [REGRESSION] [BISECTED] -rc1 breaks audio over HDMI for i915
The following change:
788d441 ALSA: hda - Use component ops for i915 HDMI/DP audio jack handling
breaks audio over HDMI on my snd_hda_intel laptop. It is the first bad commit.
This was merged for -rc1 and isn't fixed until now, so I got nervous. There are no errors in the log that stand out. I'm no sound or alsa developer, and just reverting it isn't easy since there is stuff depending on this.
I'm happy to test possible fixes and hope v4.5 not to ship with such a big regression ;)

Could you give a bit more detail about your hardware? At best, give alsa-info.sh output (run with --no-upload option). Also, give the output of dmesg, too.
In addition, what shows /proc/asound/card*/eld#*.* files? Does any of it show the proper connection state and ELD?
A simple revert of the commit is a patch like below. Does it make the HDMI audio working again?
thanks,
Takashi

It may be the audio component binding error? I met the audio component binding error in our internal kernel before. It is because the audio component name are duplicating with another i915 component and so match() function doesn't work well. But I'm not sure the ALSA kernel have the same issue. I will check it after my holiday.

It does! Everything back to normal in this case. Any idea for a proper fix? Again, I'm happy to test.

OK, then could you put some debug print in intel_pin_eld_notify() in sound/pci/hda/patch_hdmi.c? This is the callback to be called by i915 driver at enabling / disabling HDMI/DP audio. (Also, to be sure, check whether snd_hdac_i915_register_notifier() in sound/hda/hda_i915.c is called, too.)
If intel_pin_eld_notify() is registered but never called, it implies something wrong in i915 driver side. If it gets called, we need to track down: what port value was passed there, and how hdmi_present_sense() and sync_eld_via_acomp() behave there.

Put some debug prints in sync_eld_via_acomp(), e.g. check whether snd_hdac_acomp_get_eld() returns an error or snd_hdmi_parse_eld() returns an error. If you got an error, track down more deeply.
For example, the former function is defined in sound/hda/hdac_i915.c, and it calls the function i915_audio_component_get_eld() in drivers/gpu/drm/i915/intel_audio.c. You can follow what returns an error.
Similarly, the latter function is defined in sound/pci/hda/hda_eld.c. Usually you see a kernel message for parse errors, so I guess this isn't the case, though.

no error in either of the functions. size is always 0, after boot and after HDMI plugin. is that normal?

No, it means that no connection is reported back. Check the call of i915_audio_component_get_eld() as mentioned in the above. Does it return 0? Also I suppose monitor_present is set to false? If so, it implies that intel_audio_codec_enable() isn't called.
When the above is true, boot with drm.debug=0x0e, and give the kernel messages.

If i915_audio_component_get_eld() is called but returns zero, track the code flow there. It means either intel_encoder is NULL or intel_dig_port->audio_connector is NULL.

intel_pin_eld_notify() is called during HDMI plugin with
audio_ptr: ffff880242ea8800, port 1
and doesn't return early.
OK, so it was processed but the ELD wasn't updated by some reason.

snd_hdac_i915_register_notifier() is called during boot.

I'll try to look at said path, if you have no other idea in the meantime.
Put some debug prints in sync_eld_via_acomp(), e.g. check whether snd_hdac_acomp_get_eld() returns an error or snd_hdmi_parse_eld() returns an error. If you got an error, track down more deeply.
For example, the former function is defined in sound/hda/hdac_i915.c, and it calls the function i915_audio_component_get_eld() in drivers/gpu/drm/i915/intel_audio.c. You can follow what returns an error.
Similarly, the latter function is defined in sound/pci/hda/hda_eld.c. Usually you see a kernel message for parse errors, so I guess this isn't the case, though.
no error in either of the functions. size is always 0, after boot and after HDMI plugin. is that normal?
No, it means that no connection is reported back. Check the call of i915_audio_component_get_eld() as mentioned in the above. Does it return 0? Also I suppose monitor_present is set to false? If so, it implies that intel_audio_codec_enable() isn't called.
When the above is true, boot with drm.debug=0x0e, and give the kernel messages.
The above is true and -rc5 didn't fix the problem. I append "dmesg|grep drm" with drm.debug=0x0e. HDMI is plugged in at about 90 seconds in.
And how about my questions in the previous mail? Does i915_audio_component_get_eld() is called and returns 0? And is monitor_present set true or false?
i915_audio_component_get_eld() returns 0 and monitor_present is 0.
If i915_audio_component_get_eld() is called but returns zero, track the code flow there. It means either intel_encoder is NULL or intel_dig_port->audio_connector is NULL.
intel_dig_port->audio_connector is NULL!
(when called during boot and during HDMI plugin)
I'll follow it more, but I'm just posting in case anyone finds the mistake early.
thanks!

Interesting. The relevant code flow should be like:
intel_audio_codec_enable() -> acomp->audio_ops->pin_eld_notify() -> intel_pin_eld_notify() -> check_presence_and_report() -> hdmi_present_sense() -> sync_eld_via_acomp() -> snd_hdac_acomp_get_eld() -> i915_audio_component_get_eld()
So, at first, check whether intel_dig_port in both intel_audio_codec_enable() and i915_audio_component_get_eld() points to the same object address. The audio_connector must be set in intel_audio_codec_enable(), thus basically it must be non-NULL at i915_audio_component_get_eld(), too.
thanks,
Takashi

intel_dig_port is *not* the same object in these 2 places. During plugin, see:
[ 146.934091] in intel_audio_codec_enable: intel_dig_port is ffff8800a1f54000 [ 146.934121] in i915_audio_component_get_eld: intel_dig_port is ffff880244f7d000
sorry for the slow responses. I'll try to go back that direction unless again someone comes up with other suggestions.

Thanks, this makes sense. It implies that the digital port mapping is somehow wrong. There are three places setting dig_port_map[], one in intel_ddi_init(), one in intel_dp_init() and another in intel_hdmi_init(). Try to check which function creates which object assigned to which port number, together with drm.debug=0x0e debug messages.

without using drm.debug=0x0e, but by printing the kmalloc'ed objects in those 3 functions with ports, I found:
2 of them are running, only during boot:

is is correct for them to have both port 1? Any more ideas?

Adding intel-gfx ML to Cc.
Martin, is the machine SandyBridge or IvyBridge?
In anyway it's PCH_SPLIT and there can call both intel_hdmi_init() and intel_dp_init() for the same port although both functions map intel_dig_port[]. The assumption of intel_dig_port[] reverse mapping is that there is only a single intel_dig_port assigned to a port, but this doesn't look correct...

without using drm.debug=0x0e, but by printing the kmalloc'ed objects in those 3 functions with ports, I found:
2 of them are running, only during boot:
[ 2.322865] intel_hdmi_init: intel_dig_port is ffff880242564000 port 1 [ 2.322999] intel_dp_init: intel_dig_port is ffff880242f30000 port 1
is is correct for them to have both port 1? Any more ideas?

yes thanks, maybe people there have noticed this too. I can't be the only one.
Martin, is the machine SandyBridge or IvyBridge?
SandyBridge.
In anyway it's PCH_SPLIT and there can call both intel_hdmi_init() and intel_dp_init() for the same port although both functions map intel_dig_port[]. The assumption of intel_dig_port[] reverse mapping is that there is only a single intel_dig_port assigned to a port, but this doesn't look correct...

intel_dig_port->audio_connector is NULL!
(when called during boot and during HDMI plugin)
Interesting. The relevant code flow should be like:
intel_audio_codec_enable() -> acomp->audio_ops->pin_eld_notify() -> intel_pin_eld_notify() -> check_presence_and_report() -> hdmi_present_sense() -> sync_eld_via_acomp() -> snd_hdac_acomp_get_eld() -> i915_audio_component_get_eld()
So, at first, check whether intel_dig_port in both intel_audio_codec_enable() and i915_audio_component_get_eld() points to the same object address. The audio_connector must be set in intel_audio_codec_enable(), thus basically it must be non-NULL at i915_audio_component_get_eld(), too.
intel_dig_port is *not* the same object in these 2 places. During plugin, see:
[ 146.934091] in intel_audio_codec_enable: intel_dig_port is ffff8800a1f54000 [ 146.934121] in i915_audio_component_get_eld: intel_dig_port is ffff880244f7d000
sorry for the slow responses. I'll try to go back that direction unless again someone comes up with other suggestions.
Thanks, this makes sense. It implies that the digital port mapping is somehow wrong. There are three places setting dig_port_map[], one in intel_ddi_init(), one in intel_dp_init() and another in intel_hdmi_init().

On pre-HSW there can indeed be two encoders for the same port. And I'm planning to change HSW+ to follow that model as well, but I've been busy with other stuff to finish off that work [1]

So your work wouldn't fix hdmi-audio pre-HSW here?
The only question is how to pass intel_dig_port. The current code is a kind of optimization suggested after my initial patch.
Since dig_port_map[] is used only for the audio callback, we can assign it dynamically just before the callbacks.
Could you try the patch below? (It's totally untested.)
Anyways, a quick fix would be good, and if not that, remember marking future changes that fix this, for stable.
What implications would something like the following, that Takashi suggested, have on other systems?
We'd take that action as a last resort, but it should be limited to pre-HSW. So if any, we'd need the check of codec ID.
thanks,
Takashi
