[Fix] * Upstream v6.13-rc1 commit 4095cf872084 ("ASoC: amd: yc: Fix for enabling DMIC on acp6x via _DSD entry") * And two following fixes also from v6.13-rcX: commit 984795e76def ("ASoC: amd: yc: Fix the wrong return value") and commit 88438444fddd ("ASoC: amd: ps: Fix for enabling DMIC on acp63 platform via _DSD entry") [Test Case] 1) Check BIOS if microphone is turned on/off. 2) Ensure that microphone is present or not in OS (acp6x device binds or not) to match this policy. 3) Change policy in BIOS. 4) Ensure that OS behavior matches. [Where problems could occur] This basically checks whether the value in _WOV valid and enabled. Existing systems might found their microphone disabled then, but that's to respect the settings in BIOS. [Other Info] This affects kernel >= v5.19, and some of the changes have been backported to v6.12.x and v6.11.x. ========== original bug report ========== The context of it is a security risk that user turns off microphone in BIOS on Lenovo system but it still works in Ubuntu. The patch fixes it to look at what BIOS changes to decide whether to enable microphone. * https://github.com/torvalds/linux/commit/88438444fdddd0244c8b2697713adcca3e71599e ("ASoC: amd: ps: Fix for enabling DMIC on acp63 platform via _DSD entry") - Fixes: 0386d765f27a ("ASoC: amd: ps: refactor acp device configuration read logic") - in v6.13-rc5 - for >= v6.9 * https://github.com/torvalds/linux/commit/4095cf872084ecfdfdb0e681f3e9ff9745acfa75 ("ASoC: amd: yc: Fix for enabling DMIC on acp6x via _DSD entry") - Fixes: 5426f506b584 ("ASoC: amd: Add support for enabling DMIC on acp6x via _DSD") - in v6.13-rc1, v6.12.2, v6.11.11 - for >= v5.19 * https://github.com/torvalds/linux/commit/984795e76def5c903724b8d6a8228e356bbdf2af - Fixes: 4095cf872084 (ASoC: amd: yc: Fix for enabling DMIC on acp6x via _DSD entry) - in v6.13-rc3, v6.12.6 - for >= v6.13-rc1 To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/2093162/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
