[scarthgap][RFC PATCH 0/3] Add pipeWire audio stack for am62dxx

[scarthgap][RFC PATCH 0/3] Add pipeWire audio stack for am62dxx

[Paresh Bhagat]

This patch series introduces PipeWire audio support for AM62Dxx platform,
replacing PulseAudio with the modern PipeWire audio server architecture.

PipeWire is a modern audio/video server that provides low-latency, high-performance
audio processing with better resource management and flexible routing capabilities.
WirePlumber serves as the session manager, providing policy management and device
configuration for PipeWire, enabling automatic audio routing and device handling.

More info can be found here:
- https://pipewire.org/
- https://docs.pipewire.org/

PipeWire offers several advantages over PulseAudio:
- Lower latency and better real-time performance.
- Unified handling of both audio and video streams.
- Better support for professional audio applications.
- Improved security model with per-client sandboxing.
- More efficient resource usage and power management.
- Native support for modern audio formats and sample rates.

The series includes:

Patch 1: Add PipeWire configuration files with capture and multichannel setup.

Patch 2: Add WirePlumber configuration with audio defaults service.

Patch 3: Enable PipeWire audio stack in tisdk-default-image for am62dxx.

This implementation provides a complete audio solution with ALSA and PulseAudio
compatibility layers, ensuring backward compatibility while leveraging PipeWire's
advanced capabilities.

As per pipewire docs [0], Audio/Source should be in quotes.

FILESEXTRAPATHS should be before SRC_URI so that bitbake knows where to
find files mentioned in the SRC_URI.

Nitpick, packaging entire ${sysconfdir} might not be a best practice, best
would be to package only the required files or the pipewire.conf.d dir. 

FILES:${PN} += "${sysconfdir}/pipewire/pipewire.conf.d/*.conf"

We do not directly bbappend recipes to maintain yoctoproject compatible 
status.  Please check other bbappends in meta-arago for examples on how 
to do this properly.  For example: 
meta-arago-distro/recipes-multimedia/libtiff/tiff_%.bbappend


This same comment applies to the other patches where you add bbappend 
files as well.

And since this is to add 2 extra conf files, alternatively this could be a 
completely separate recipe.

As per the systemd manual [0], with "Wants=" the service will still run
if wireplumber fails. From the script below I see that is not the
intension. "Requires=" would be the correct way.

FILESEXTRAPATHS should be before SRC_URI.

As per yocto docs [1], systemd bbclass will take care of installing the service files 
and the lines installing the service files can be dropped. But for this
to work inherit systemdm, should be above do_install().

[scarthgap][RFC PATCH 3/3] tisdk-default-image: Add audio server support for am62dxx

[Paresh Bhagat]

Add pipewire and wireplumber audio stack support for am62dxx:
- Include pipewire core components and tools
- Add ALSA and PulseAudio compatibility layers
- Include wireplumber session manager
- Add GStreamer pipewire plugin
- Configure pipewire with proper modules and plugins

As per yocto docs [0], `pn-pipewire` would not work inside an image
recipe. I suggest dropping PACKAGECONFIG lines, Instead put the
PACKAGECONFIG lines in `pipewire_%.bbappend`

```
PACKAGECONFIG:append:am62dxx = " pipewire-jack pipewire-modules pipewire-spa-plugins"
PACKAGECONFIG:remove:am62dxx = " jack"
```

I'm sure at some point we will want to push the "more modern" pipewire 
to other boards as well.  What is the reasoning for only doing this on 
am62d?

Please create a PIPEWIRE variable that contains the above list and then:

IMAGE_INSTALL:append:am62dxx = " ${PIPEWIRE}"

Also, for ease of looking up packages, please sort the list alphabetically.


> +PACKAGECONFIG:append:am62dxx:pn-pipewire = " pipewire-jack pipewire-modules pipewire-spa-plugins"
> +PACKAGECONFIG:remove:am62dxx:pn-pipewire = " jack"

Agree with Yogesh.  This is not appropriate in this file.  This should 
be in a pipewire bbappend.

Huh? pipewire-modules and pipewire-spa-plugins are not PACKAGECONFIGs, but 
packages...

No leading space is needed here.

Or rather generically in the distro config, as I suggested last week.
