** Description changed: - This bug is for tracking purpose. + These 2 patches were merged to upstream kernel from v5.12, no need to + send them to impish/oem-5.13/unstable kernels. And this patch is + already in the oem-5.10 kernel, for focal kernel, since focal kernel + doesn't support soundwire audio, these 2 patches are useless for focal + kernel. + + + [Impact] + The Dell precision 5760 is a TGL-H machine, and it has soundwire audio + design, when running the hirsute kernel, the audio driver fails to + load sof-firmware, then the whole audio fails to initialize and fails + to work. + + [Fix] + Backport 2 patches, these will remove hardcoded firmware name and + allow load firmware according to the firmware name defined by pciid + + [Test] + Booting the patched kernel, check dmesg, there is no errors about + loading audio sof-firmware, playsound to spk and headphone, all worked + well, record sound from internal mic and external mic, all worked well. + + [Where problems could occur] + The patch remove the hardcoded firmware for all TGL soundwire machines, + this could make the TGL soundwire machines fail to load the + sof-firmware then the whole audio fail to work. But this possibiliy is + low, since we tested the patches on different TGL soundwire machines, + all worked well.
