** Description changed:
[SRU Justifications]
[Impact]
Modern Intel platforms (RPL, MTL, LNL...etc) connect audio codecs on
Soundwire instead of HDA, but the soundwire devices are not well reflected on
the alsa-info report. In order to meet the increasing demands for SoundWire
debugging, we must enable alsa-info to provide more information about SoundWire.
[Fix]
- Backport the upstream commit cc0bcef81389 ("alsa-info.sh: log SoundWire
devices reported in ACPI"). The reported information can reflect which
soundwire devices are connected and which soundware link the device connects
to. It's quite sufficient for what driver should be ready and what
tplg/firmware file should be loaded.
+ Backport the upstream commit cc0bcef81389 ("alsa-info.sh: log SoundWire
devices reported in ACPI") of v1.2.12. The Oracular is expected to sync with
v1.2.12 and we may not have to backport to Oracular. The reported information
can reflect which soundwire devices are connected and which soundware link the
device connects to. It's quite sufficient for what driver should be ready and
what tplg/firmware file should be loaded.
[Test Case]
- 1. Find a machine with (RTK/Cirrus/TI) Soundwire audio device.
+ 1. Find a machine with (RTK/Cirrus/TI) Soundwire audio device.
2. Install the new alsa-utils debian package
3. Execute `alsa-info` to generate the report
- 4. Check if the section "ACPI SoundWire Device Status Information" exists in
the output report.
+ 4. Check if the section "ACPI SoundWire Device Status Information" exists in
the output report.
[Where problems could occur]
It's simply an additional soundwire information when ACPI exposed the
soundwire device. The risk for regression is low.
+
+ [Other Info]
+ Verify if the official Oracular starts from version v1.2.12 to determine if
we have to land it on Oracular.
