Amixer kctl setting should not impact on the jack connection status. In hdac_hdmi_present_sense(), it will call hdac_hdmi_jack_report() to report the monitor connection status. This means the jack status represents the HDMI monitor connection status.

However, in the original code, hdac_hdmi_set_pin_port_mux() will also call hdac_hdmi_jack_report() when "pinx-porty Mux" setting is changed. This means the kctl setting will also impact on the jack status regardless of the monitor connection. This will introduce some troubles. For example, assuming the original amixer setting is: "pin5-port0 Mux" is set "cvt 2" "pin5-port1 Mux" is set "cvt 2" HDMI uses pin5 and HDMI is connected to the machine. After booting the system, setting "pin5-port1 Mux" to "NONE" will trigger hdac_hdmi_set_pin_port_mux() calling hdac_hdmi_jack_report(false) In this situation, user space will get the wrong status.

This patch removes calling hdac_hdmi_jack_report() in hdac_hdmi_set_pin_port_mux(). This makes jack status always represents the monitor connection status.

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.

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

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?

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.

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.

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.

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.

thanks,

Takashi

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

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?

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.

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.

...

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.

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.
