From: Libin Yang <libin.yang@intel.com>

This patch does the following actions:
1) move snd_soc_card_jack_new() from machine driver to codec driver.
   This is because the jack information is more lated to the codec
   Also this patch calls snd_jack_add_new_kctl() to export the jack kctl
   to userspace.

2) jack is bound to pcm in origal code. The patch binds jack to pin-port.
   This mean each pin-port (3x3) has a jack. pin-port is used for DP-MST
   mode. The port means device entry for DP-MST in hdac_hdmi
   As hdac_hdmi allows user to map the pin-port to a pcm manually, the jack
   is bound to pcm is not accurate.
   However, PA assumes jack is bound to PCM for the legacy mode.
   For example, for ubuntu, in
   /usr/share/pulseaudio/alsa-mixer/paths/hdmi-output-x.conf uses
   "Jack HDMI/DP,pcm=n" to find which jack event is used.
   This main issue is: pcm number is fixed (3, 7, 8, 9, 10) for hdmi in
   legacy mode. But it is not always the same for ASoC hdmi audio.

The question is what brings this change practically.  On the legacy
driver, as the jack is bound with the PCM, user-space (typically PA)
who receives a jack connection event opens simply the corresponding
PCM substream.  Now, for ASoC:
  1. Which PCM substream?
  2. How to set up the routing?

I assume the 1 doens't matter, any substream, unlike the legacy case.
But how is 2 done automatically?


thanks,

Takashi

For the legacy HDA, there are 2 mode (dynamic pcm assignment (DPMST) and 
static pcm assignment (NON-DPMST)).
1) For static pcm assignment, pcm is always statically mapped to pin. 
For example, pcm1 <=> pin 1; pcm <=> pin 2 and so on. So it is the same
to bind jack to pcm or to pin.
2) For dynamic pcm assignment, in generic_hdmi_build_jack(), the jack
is bound to PCM when it is created (spec->pcm_rec[pcm_idx].jack). We will
find the jack by pcm_idx. And when monitor is connected to a pin, 
update_eld() will be called. In update_eld(), it will call 
hdmi_attach_hda_pcm() to find a pcm to bind to the pin. So it can find a 
jack (from the pcm) and report its status to userspace.

So in a word for legacy HDA, it can always find a PCM (no matter in static 
mode or in dynamic mode) when the monitor is connected to a pin. This
means it can always update the status of to userspace that the pcm 
status is changed.

However, in hdac_hdmi, there is no such dynamic pcm assignment. And it
is not statically assignment of pcm to pin. PCM is statically bound to cvt.
hdac_hdmi allows user to assign a cvt to a pin with alsamixer ( in function
hdac_hdmi_set_pin_port_mux(), so this function maps the pin to the pcm).
As user may assign NONE pcm to a pin in alsamixer, this means a pin can
be assigned none of pcms. So if we mapped jack to pcm, we may not find 
any jack for the pin when a monitor is connected to the pin. This means
driver can't notify userspace of the monitor connection.
As you know, PA will use the monitor connection status to decide whether
to user it or not. So this is the problem. The root cause is pcm is bound to
cvt. And pin may be not bound to any pcm (This is the difference from the
legacy hda).

In my patch, as jack is bound to pin-port, so it can always notify userspace
that a monitor is connected. We can use configuration in /usr/share/alsa/
ucm or /usr/share/pulseaudio to configure the amixer to assign a pcm
to the pin (monitor). And userspace can playback on the monitor now.

Libin

Right, that's why the jack control has a pcm suffix.  It is bound with
the PCM stream in the end, so user-space can simply open it.

Then please prepare the UCM stuff at first and make sure that
everything works with the proposed change.  The kernel changes can be
merged once after all things get ready.

OK. I will prepare the UCM and PA configurations to check it works well and
the purpose is patch should be compatible with the old drivers.

Hi Takashi,

Sorry for a long delay for the hdmi jacks. I was busy on another critical issue
last 2 weeks. I have worked out the UCM configuration files. Please check the 
attachment. It is a long file, so I use the attachment instead of the patch mode.
Based on my test, it works well. Could you please help review if the configuration
file is OK or not. I will do more test on the meantime, including DPMST and
NON-DPMST.

Regards,
Libin

With some more tests on the new hdmi jack with UCM configuration, I found
that the kernel patch can always notify the jack hotplug event to userspace
correctly. However, the userspace can't set the amixer correctly based on
the UCM configurations sometimes.

Here is the details:
There are 3 PCMs on Intel platforms. Let's call them pcm1, pcm2, pcm3.
And there are 3 pins (pin5, pin6, pin7). For DPMST, and each pin has 3 ports:
port0, port1, port2.

For non-DPMST, we can set pin5 <=> pcm1, pin6 <=> pcm2, pin7 <=> pcm3.
This can always work.

For DPMST, as there are 9 ports using 3 pcms. So we should assign
1 pcm to 3 ports. For example, pin5-port0, pin6-port1 and pin7-port2
are using pcm1;  pin5-port1, pin6-port2 and pin7-port0 are using
pcm2; pin5-port2; pin6-port3 and pin7-port1 are using pcm3.
In this setting, we should setting the ConflictingDevice in UCM.
For example, pin5-port0 is conflicting with pin6-port1 and pin7-port2.
Hui and I found if we set one device conflicting with 2 devices, the
amixer setting will be wrong and it will not following UCM configuration
setting when we are hotplugging the monitors.
Hui and I thought this may be the alsa-lib or pulseaudio issue.
Do you have some ideas that if we can fix the issue of 3 devices
are conflicting? Thanks.

Regards,
Libin

How wrong would it behave?  Only one of them is done?

You can try alsaucm directly without PA, too.
But in general the conflicting device management is done in PA, so I'd
begin with tracking the PA UCM code at first.

Yes, only the 1st conflicting device is handled.

for example:

pin5-port0 has two conflicting devices: pin6-port1 and pin7-port2,

When pin5-port0 is active in the pulseaudio, I can see the 
pin6-port1.DisableSequece and pin7-port2.DisableSequence are called 
according to pulseaudio's log, but it looks like the commands only in 
the 1st device (pin6-port1.DisableSequence) are executed.

To call conflicting devices' disablesequence, the pulseaudio will call 
snd_use_case_set(ucm->ucm_mgr, "_disdev", dev_name) twice, but only the 
1st time calling takes effect.

Sorry for delay reply. I take annual leave these days. 
The behavior is like Hui's description. Thanks for the suggestion. I will
try alsaucm firstly for the debug.

If you reached at that point, you can continue tracking in alsa-lib :)
If it's some weird behavior in set_device(), it must be either the
list management failure in UCM or execute_sequence() misses
something.
