From Fedora Project Wiki

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

Most of the following information comes from #aarch64-laptops on OFTC, #fedora-arm on and arm[AT] Upstream information changes daily, so this page may be outdated.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
    • Need to have ModemManager-1.22.0-1.fc40.aarch64 or newer installed, then follow the documented steps to unlock the modem
  • Virtualization is not yet available. The UEFI is not yet exposing the EL2 (exception level), which is required to run VMs
  • The system does not suspend correctly so you need to poweroff if leaving unused
  • Wifi address is randomized after each boot
