Hello, you may want to ask also on IRC, OFTC server, #aarch64-laptops channel

Thanks Dennis,

I created the file with the following contents

install_items+=" /lib/firmware/qcom/sc8280xp/LENOVO/21BX/qcdxkmsuc8280.mbn /lib/firmware/qcom/sc8280xp/LENOVO/21BX/qccdsp8280.mbn /lib/firmware/qcom/sc8280xp/LENOVO/21BX/qcadsp8280.mbn /lib/firmware/qcom/sc8280xp/LENOVO/21BX/qcvss8280.mbn "

The last one is the video firmware described here (https://github.com/jhovold/linux/wiki/X13s#userspace-dependencies) which I manually added from the windows cabs. Not sure if this is needed for mainline kernel or just for the WIP branches but included just incase.

I think I could have included the firmware in compressed xz form but extracted it (unxz) as was unsure exactly how compressed firmware is handled. And then ran dracut --force to regenerate.

USB devices were partially working without the firmware, but as I wasn't booting from USB device I don't know if they were being reset during boot.

Thanks again for your help. Battery level is back working (and so is external monitor).

The move from dracut 059 to 060 led to some additional modules being in the initrd. A workaround is to add a dracut config snippet that includes the firmware in the initrd. after putting the file in /etc/dracut.conf.d/ you will need to rebuild the initrd. ideally the driver should try and reload the firmware once the root filesystem becomes available. a side effect of the modules being included in the initrd is that USB booting should work without the need blacklist qcom_q6v5_pas as it is what has been included and works here. What is not clear to me currently is if usb would work correctly without the firmware.

Hi all,

I have been using Fedora 40 Beta on my Lenovo X13s (followed instructions on https://fedoraproject.org/wiki/Thinkpad_X13s, thanks for those, very helpful).

However, last couple of kernel updates have brought regressions which I think are due to failing to load firmware.

dmesg has lines like : -

[ 2.596550] remoteproc remoteproc0: Direct firmware load for qcom/sc8280xp/LENOVO/21BX/qcadsp8280.mbn failed with error -2 [ 2.606506] remoteproc remoteproc1: Direct firmware load for qcom/sc8280xp/LENOVO/21BX/qccdsp8280.mbn failed with error -2

This has the impact that the power monitor doesn't seem to be able to pull battery status (pd-mapper is installed and running)

Rebooting and selecting kernel 6.8.4-300.fc40.aarch64 and this issue disappears. Is this happening to any other X13s owner? Any help a debugging the issue/resolving it without downgrading kernel would be appreciated.

Thanks

Andrew Spooner
