firmware-sof doesn't have an SRU exception[1] that allows it to add such bulk changes without a specific process.
This bug here claims to be enabling just "cs42l43 and cs35l56 audio on Intel LNL", but the commit is far more reaching than that claim. If I look at the previous update[2], only one topology file was added[3]: sof-tplg-v2.2.13/sof-rpl-cs42l43-l0.tplg > 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. This rationale is not always true. Such a type of update can also bring with it other bugs, which would mean a regression for ubuntu stable release users. See [4] for some examples and arguments in favor of minimal changes. Why do you claim that bringing in all those other 90+ topology files is better and less risky than updating just the one we need to fix this bug? I'm definitely not the expert in this package, but I see a huge amount of changes, to other pieces of hardware, and I have to wonder: - how can we be sure we are not regressing all those other sound cards? - we are testing just "intel NL", what about all the other changes? - Why can you claim that this update will not affect other hardware? You state, in the bug description: "It may break cirrus audio support.". But I see many topology files that don't seem to be limited to "cirrus audio". What is the risk in updating/adding just the files we need for "cs42l43 and cs35l56 audio on Intel LNL"? 1. https://wiki.ubuntu.com/StableReleaseUpdates#Documentation_for_Special_Cases 2. https://launchpad.net/ubuntu/+source/firmware-sof/2023.12.1-1ubuntu1.4 3. https://git.launchpad.net/ubuntu/+source/firmware-sof/commit/?h=ubuntu/noble-devel 4. https://documentation.ubuntu.com/sru/en/latest/explanation/requirements/#explanation-minimal -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2106394 Title: [SRU] enable cs42l43 and cs35l56 audio on Intel LNL Status in HWE Next: New Status in alsa-ucm-conf package in Ubuntu: Fix Committed Status in firmware-sof package in Ubuntu: Fix Released Status in linux package in Ubuntu: New Status in linux-firmware package in Ubuntu: In Progress Status in alsa-ucm-conf source package in Noble: Fix Committed Status in firmware-sof source package in Noble: Incomplete Status in linux source package in Noble: Won't Fix Status in linux-firmware source package in Noble: Fix Committed Status in alsa-ucm-conf source package in Oracular: Fix Committed Status in firmware-sof source package in Oracular: Incomplete Status in linux source package in Oracular: Fix Committed Status in linux-firmware source package in Oracular: Fix Committed Status in alsa-ucm-conf source package in Plucky: New Status in firmware-sof source package in Plucky: Fix Released Status in linux source package in Plucky: New Status in linux-firmware source package in Plucky: New Bug description: [Impact] No audio input/output for cs42l43 and cs35l56 on Intel LNL of ThinkPad.
