Page to keep track of Linux support development for Thinkpad X13s (SoC codename sc8280xp), the first Thinkpad with ARM CPU.

Most of the following information comes from #aarch64-laptops on OFTC, #fedora-arm on Libera.chat and arm[AT]lists.fedoraproject.org. Upstream information changes daily, so this page may be outdated.

Bootable images

Fedora Rawhide images are bootable as of the 15th of December, 2023, with some additional user interaction.

  • The kernel must be booted with arm64.nopauth clk_ignore_unused pd_ignore_unused rd.driver.blacklist=msm
  • A recent firmware must be on the machine, and the linux/DT mode must be selected in the FW menus.
    • Recommend minimum version:
      • Version: N3HET84W (1.56 )
  • A 6.5 or newer device tree must be placed on the ESP of the internal NVMe disk and named sc8280xp-lenovo-thinkpad-x13s.dtb
  • To boot from USB, modprobe.blacklist=qcom_q6v5_pas must be added to the boot arguments. This keeps the USB from being reset and the storage device from being renamed mid-boot.
  • Once the system is running, installing the x13s copr, will pull in the remaining dependencies and correct a few configuration items: 
    • dnf copr enable jlinton/x13s; dnf install x13s
      • Reboot
  • After major kernel updates, it is probably wise for the time being to run 
    • cp /boot/dtb-`uname -r`/qcom/sc8280xp-lenovo-thinkpad-x13s.dtb /boot/efi

Known Problems

  • Audio works but is quiet
  • TPM support is missing
  • 5G Modem
    • While waiting on a new release of ModemManager we can take the following steps
sudo ln -s 105b /usr/share/ModemManager/fcc-unlock.available.d/105b\:e0c3
sudo mkdir -p /etc/ModemManager/fcc-unlock.d
sudo ln -sft /etc/ModemManager/fcc-unlock.d /usr/share/ModemManager/fcc-unlock.available.d/*
