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).

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. > > 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). 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. > > 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. 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. --srini > > Johan

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). > How do you test it?

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. > > 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. > > 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.

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. thanks, Srini > > Johan

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. thanks, srini

I don't know how best to implement it, but we shouldn't necessarily let that determine the user experience. > Or somehow find a way to not let the pipewire talk to devices which are > not connected. 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). Johan

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.

How is this handled for the native HDMI playback on platforms like Dragonboard 820c?

Could you please point out why there are just 3 jacks? 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. --srini

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 Srinivas Kandagatla (4): ASoC: qcom: q6dsp: parse Display port tokens ASoC: qcom: common: add Display port Jack function ASoC: qcom: sc8280xp: add Display port Jack ASoC: qcom: sm8250: fix a typo in function name sound/soc/qcom/common.c | 29 +++++++++++++++++++++++++++++ sound/soc/qcom/common.h | 3 +++ sound/soc/qcom/qdsp6/topology.c | 26 ++++++++++++++++++++++++++ sound/soc/qcom/sc8280xp.c | 14 ++++++++++++++ sound/soc/qcom/sm8250.c | 4 ++-- 5 files changed, 74 insertions(+), 2 deletions(-)
