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.

Regards,
Libin

alsa-info and dmesg are appended, and

root@laptop:/home/martin/dev# cat /proc/asound/card*/eld#*
monitor_present		0
eld_valid		0

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.

intel_pin_eld_notify() is called during HDMI plugin with

audio_ptr: ffff880242ea8800, port 1

and doesn't return early.

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.

OK, so it was processed but the ELD wasn't updated by some reason.

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.

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?

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.

i915_audio_component_get_eld() returns 0 and monitor_present is 0.

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.

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:

[    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?

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...
