[PATCH v2 0/4] ASoC: qcom: display port changes

[srinivas.kandagatla]

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patchset adds support for.
	1. parse Display Port module tokens from ASoC topology
	2. add support to DP/HDMI Jack events.
	3. fixes a typo in function name in sm8250

Verified these patches on X13s along with changes to tplg in 
https://git.codelinaro.org/linaro/qcomlt/audioreach-topology/-/tree/topic/x13s-dp?ref_type=heads
and ucm changes from https://github.com/Srinivas-Kandagatla/alsa-ucm-conf/tree/topic/x13s-dp

Thanks,
Srini

Changes since v1:
	- Fixed unused variable warning.
	- fixed warning 'break;' to avoid fall-through

[PATCH v2 1/4] ASoC: qcom: q6dsp: parse Display port tokens

[srinivas.kandagatla]

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

DP Module needs to know the data format type which is specified in the
tplg file, parse that info before setting up the module.

The function is called dp_jack_setup() so shouldn't the parameters
reflect that and be called dp_jack etc. for consistency (i.e. even if
you plan on using this interface also for hdmi)?

It looks like your UCM changes are still muxing the speaker and *each*
displayport output so that you can only use one device at a time (i.e.
only Speaker or DP1 or DP2 can be used).

As we discussed off list last week, this seems unnecessarily limited and
as far as I understood is mostly needed to work around some
implementation details (not sure why DP1 and DP2 can't be used in
parallel either).

Can you please describe the problem here so that we can discuss this
before merging an unnecessarily restricted solution which may later be
harder to change (e.g. as kernel, topology and ucm may again need to be
updated in lock step).

From what I could tell after a quick look, this series does not
necessarily depend on muxing things this way, but please confirm that
too.

Shouldn't these be split in dedicated HDMI and DP jacks too? What if you
have a machine with HDMI and DP jacks which would otherwise both claim
"HDMI/DP0"?

that is true.

What is the use-case to use more than one audio sink devices at the same 
time for a laptops?

How do you test it? I never tested anything like that on a full desktop 
setup.

May be some manual setup in Wireplumber, but not 100% sure about 
multiple stream handling.

It is absolutely possible to run all the streams in parallel from the 
Audio hardware and DSP point of view.

One thing to note is, On Qualcomm DP IP, we can not read/write registers 
if the DP port is not connected, which means that we can not send data 
in such cases.

This makes it challenging to work with sound-servers like pipewire or 
pulseaudio as they tend to send silence data at very early stages in the 
full system boot up, ignoring state of the Jack events.

These patches have nothing to do with how we model the muxing in UCM or 
in tplg.

so these can go as it is irrespective of how we want to model the DP 
sinks in the UCM or tplg.

I can imagine streaming audio and video to a TV (or audio to a soundbar)
over DP while playing systems sounds and doing video conferencing using
the internal speakers (or the other DP port).

You can select the sink per application in pavucontrol. Just verified
that playing audio over the 3.5 mm jack while playing system sounds
using the internal speakers works just fine.

This bit sounds like it can and should be worked around by the driver to
avoid hard-coding policy which would prevent use cases such as the ones
mentioned above.

These map to the Jack's added as part of qcom_snd_dp_jack_setup and 
belong to DISPLAY_PORT_RX_0, DISPLAY_PORT_RX_1, DISPLAY_PORT_RX_2.

If its going via USB-C DP controller it will be either DP or an HDMI ?

This is the most common naming for the USB-C DP/HDMI jack events.

Qualcomm LPASS in some older SoCs had a dedicated HDMI interface which 
is different to this one.

Usual Other ways to connect HDMI is via external HDMI Bridge using I2S 
interface which totally different to this DP interface.

So none of these will conflict.


hope this clarifies.

This is not simple as you say. We have to fit these into a proper DPCM.
Either we have a dummy Backend connected for each of these pcm 
sub-devices when DP port is not connected and then switch back to DP 
when its connected.

Or somehow find a way to not let the pipewire talk to devices which are 
not connected.

It will always be DP out of the machine even if an adapter can convert
to HDMI internally.

The DRM ports are called "DP-1" and "DP-2" so it seems we should match
that.

> This is the most common naming for the USB-C DP/HDMI jack events.

It looks like some Intel machines use names like "HDMI/DP, pcm=%d Jack"
(with a pcm device number), but we also have "DP Jack". Not sure which
are are used with USB-C, though. (Or if the former actually support HDMI
altmode.)

Sure, but if there's ever a design with such a port then it will be
called "HDMI Jack" and then the "HDMI in "HDMI/DP0 Jack" is unnecessary
and confusing when it is always DP out.

I don't know how best to implement it, but we shouldn't necessarily let
that determine the user experience.

Yes, perhaps it requires a change in user space.

But it seems the kernel should be able to fake whatever probing user
space currently does to determine if the there is a DP jack (even when
there is nothing connected).

I checked this on my machine which has usb-c and I can confirm using 
HDMI/DP naming for these jack.

Either way I don't mind having any names, but my point here is to be 
more consistent across.

Hi Srini,

I tested this series on SM8550 with tplg in [1] and ucm in [2]. But the 
kernel output errors attached below. Headphone does work properly 
without DisplayPort in the ucm.

What could be the possible cause of this? Is there any significant 
change from sc8280xp to sm8550?

Is the DP cable connected?

if its not connected the dsp will throw this error.

due to this issue I did workaround this issue by modeling it as 
conflicting device to Speaker in x13s ucm.

I see in your ucm setup its not the case.
which is why you might be hitting this issue.

Can you try
amixer -c 0 cset iface=MIXER,name='DISPLAY_PORT_RX_0 Audio Mixer 
MultiMedia2' 1
aplay -D plughw:0,1 some-wav-file.wav

both with and without display connected.

I'm sure that the cable is connected and I have desktop on external display.
If it's not connected, kernel gives the following error when using aplay:

I fear it is till not consistent. On the Intel laptop I see following
jacks:

numid=18,iface=CARD,name='HDMI/DP,pcm=3 Jack'
numid=24,iface=CARD,name='HDMI/DP,pcm=7 Jack'
numid=30,iface=CARD,name='HDMI/DP,pcm=8 Jack'

On the other hand Mediatek and RockChip use just 'DP Jack'.

I'd suggest settling on the latter option. We are closer to MTK and
RockChip rather than Intel.

BTW: a platform can easily have 4 (x1e8100) or even 8 (sc8280xp) DP
outputs. Could you please point out why there are just 3 jacks?

Using hdmi_ prefix for DP jacks is counterintuitive at best.

I'd suggest either using DISPLAY_PORT_RX here or adding a comment to
point out that DP RX ids are not sequential.

Consider multi-seat setup, with each monitor having its own set of
keyboard, mouse, headphone and user behind it.

How is this handled for the native HDMI playback on platforms like
Dragonboard 820c? As far as I was able to test, playback fails with -EIO
if HDMI output is not enabled or if the DVI monitor is connected.

that is fine with me.

The CRD platform that I have access to has 3 ports which is why I 
started with 3 ports, but we can add more ports as and when we can 
really test them.

For sm8550 you would need this patch for tplg

https://git.codelinaro.org/krzysztof.kozlowski/audioreach-topology/-/commit/d8ef47bc85700a7cdfabee5e06808d9f359b0a26

can you try this as the Container CAP Id changed for platforms from sm8550.

Kryzstof verified Display port tplg and these patches on x1e80100.

That exactly solved the previous problem, thanks!

Hot-unplugging type-c caused `fail to close APM port` error, and DP 
audio will no longer work after that. But I guess that would be another 
issue anyway :)
