Revision as of 18:02, 26 November 2024

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 Libera.chat and arm[AT]lists.fedoraproject.org. Upstream information changes daily, so this page may be outdated.

Bootable images

Fedora 41 GA works relatively well OOTB. The Workstation raw image can be used with the following additions:

  • The kernel must be booted with arm64.nopauth clk_ignore_unused pd_ignore_unused
  • A recent firmware must be on the machine, and the linux/DT mode must be selected in the FW menus.
    • Recommend minimum version:
      • Minimum: Version: N3HET84W (1.56 )
      • Latest: Version: N3HET88W (1.60 )
  • 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 on Fedora 40 with a 6.8 kernel or older, 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. Note that this is not needed with 6.11 kernel in Fedora 41.
  • 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 follow the documented steps to unlock the modem
  • Virtualization is not 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
  • Camera is not working. There are patches going upstream. You need to add cma=128M
  • Bluetooth doesn't always work
