Bug description:
[SRU Justifications]
========== linux-firmware ==========
[Impact]
Audio output doesn't work on Dell Bolan platforms with CS35L56 speaker
amplifiers
[Fix]
This requires following firmware blobs:
-
https://github.com/CirrusLogic/linux-firmware/commit/367fda8e56d7dda4c138438493e2bf6b9b92ce7b
which is not landed in linux-firmware mainline yet.
[Test Case]
1. Boot up the machine of Dell Bolan platform with CS35L56 speakers
2. Verify the sof-lnl-cs42l43-l0.tplg in in the
/lib/firmware/intel/sof-ipc4-tplg/
3. Verify with checking the output of `aplay -l` command with valid sof
output device. Should never be dummy output.
[Where problems could occur]
It only affects the Dell Bolan platforms with the new CS35L56 amplifier.
Should be low low risk of regression
========== firmware-sof ==========
[Fix]
This requires following tplg file in firmware-sof
- sof-lnl-cs42l43-l0.tplg
upstream firmware-sof 2.11 will have this tplg file included.
[Test Case]
1. Boot up the machine of Dell Bolan platform with CS35L56 speakers
2. Verify with the linux-firmware with new CS35L56 amplifier support.
3. Verify with checking the output of `aplay -l` command with valid sof
output device. Should never be dummy output.
[Other Info]
The name of sof-lnl-cs42l43-l0.tplg includes useful information which
indicates that the topology is for for the cs42l43 codec connected to soundwire
bus 0 w/o other soundwire devices connected on 1/2/3. It only affects the
machines which has exactly the same soundwire configuration. The upstream
commit of a newer version usually include the topology files for the new
platforms or missing configuration on old platforms. It would be better to
catch up with upstream to have these configuration which can support more
configurations we could be missing in the future. The the addtional
0002-Add-SOF-v2.11.1-signed-Intel-binaries-for-MTL-LNL-AR.patch, it's required
for each new Intel Platform and signed by Intel. In the case, the tplg file
specify the `lnl`, a signed LunarLake DSP FW will be necessary. It would be
better to have the Intel signed DSP FW up-to-date.
[Where problems could occur]
Although there're lots of new tplg files added, but they are mostly for
missing configuration on old platforms or newly added for next-gen Intel
platform. And they are specified for particular soundwire configurations which
can hardly affect the existing machines. The risk for regression may come from
sof-hda-generic-xxx.tplg which is for generic HDA. I'll consider it as low risk.
