@elorriaux that looks like a known issue where an external NVIDIA GPU is used, the log is similar to #1658

@kv2019i I think you fixed this with #1731, but can it be back-ported to 5.5-stable?

[elorriaux]

@plbossart thanks Pierre for the quick answer. Actually you're wright my IT disabled the intel graphics card, I did not pay attention to that. If I reactivate it I can go through that error but my X server does not work anymore, and my other distro does not boot anymore. So I will probably have to

I was also wrong regarding the firmware, the next error is that sof-cfl.ri is missing.

[kv2019i]

@plbossart Ack, this is fixed by upstream commit "ASoC: SOF: Intel: hda: allow operation without i915 gfx" . This is currently not queued even for 5.6, so only in 5.7 queue. Mark wasn't happy recently with the volume of changes to 5.5, so not sure if this is accepted. There is going to be a fair amount of patches, so maybe this is still worth it.

UPDATE: @plbossart I'll try the patches on top of 5.5.y and if seems good, I'll send a mail to alsa-devel about this. Not 100% what's the Mark preferred process to pick up older patches for stable, but I'll follow what Jaroslav did (the most recent example I could find).

[kv2019i]

@plbossart @elorriaux Hmm, backport to 5.5.y is not really straightforward. A minimum set requires many more patches than the one mentioned. I backported three patches, but then realized that the upstream fix depends on the refactored machine selection code (in 5.5.y, bus probe is done after machine driver selection, so the upstream logic to ignore lack of i915 won't work). Backport to 5.5.y within limits of stable kernel rules (all patches need to be in upstream, <100 lines), does not seem feasible.

[plbossart]

@kv2019i I think we need to start thinking about a 5.5 SOF branch, it'd still be useful for a number of people who have non-functional devices. You can argue that 5.6 is just around the corner though but some distros will stick with 5.5. Some will even stick with 5.4 LTS.

Hi, I tried to configure bumblebee to keep intel built-in grapĥics card enabled and it solves my initial error, I can go further but it fails to load the firmware (I symlinked sof-cfl.ri tp sof-cfl.ri):

[plbossart]

@elorriaux you sure about the symlink? If the file was in the right location it'd be a different error...

[elorriaux]

@plbossart That's the first thing I checked. You are confirming that I should continue to check in that direction.

I guess that read permission on cof-cnl.ri should be sufficient?

I simply took sof-cnl-v1.4.2.ri from https://github.com/thesofproject/sof/releases and copied it to /lib/firmware/intel/sof/sof-cnl.ri and then created a sof-cfl.ri symlink. I'll try to copy it directly with the right name without symlink.

[plbossart]

@elorriaux try to use the go.sh script, it does all the symlinks for you

[plbossart]

[elorriaux]

Reinstalled all the firmwares with the go.sh script, not exactly the same error msg:

@elorriaux what was the script output ? You will need to run as root/sudo as it will be installing files under /lib/firmware (or wherever your distro places system firmware)

[elorriaux]

everything was done with root account.

If you pay attention on dmesg logs, the usage of the script to install firmware causes one additional line compared to the firmware install I did manually:

4 seconds, which means early boot... Do you have an initramfs? It's possible you may need to add the /lib/firmware/intel/sof and /lib/firmware/intel/sof-tplg folders inside the initramfs.

root ignores read/write permissions and so should the kernel module itself.
