description |
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. |
