** Description changed: - This bug is for tracking. + For focal and oem-5.6 kernel, these all 5 patches are needed, for + groovy kernel, since the 1st patch is already in the 5.8 kernel, the + groovy kernel only needs the last 3 patches [3/5, 4/5 and 5/5]. + + [Impact] + the alsa upstream worte the ucm3 files for amd renoir audio, but to + load the ucm3, it depends on the kernel module name, and the upstream + ucm3 needs the name snd-xxx, so we need to backport the patches + from mainline kernel to change the kernel module name to meet ucm3 + requirement. BTW, there are some dmic dynamically detection patches, + we integrate them too. + + [Fix] + Backport 4 patches from upstream. + + [Test Case] + boot the kernel with these patches on amd renoir machines (lenovo + machines), the audio driver works well (via command line like + aplay or areord), then upgrade the alsa-lib and alsa-ucm-conf to + 1.2.3.2, now we could see the audio devices from gnome, and they work + well. + + [Regression Risk] + Low, this SRU are only specific to soc/amd/renoir, and we already + tested on 2 lenovo machines, their audio worked as before.
